  • Where is thermal transfer printing used?

Thermal transfer printing is a method of applying an image to an intermediate medium (tape or ribbon (English)) with its further transfer to the prepared material. The fixing process is carried out by short-term exposure (from 5 to 30 seconds) of temperature from 120 °C to 190 °C. Thermal transfer printing is characterized by high durability of fixing the ink on the material. At the same time, it is beneficial to use this type of printing even with a small order.

How does thermal transfer printing work?

Thermal transfer printing is preferred by many today. This is due to the wide scope of its application. What does she represent? With this printing method, the ink is applied to the substrate using thermal transfer ribbons that are heated at designated locations.

Thermal transfer printing allows you to choose a material that has optimal protective properties and performance characteristics.

For the first time, the thermal transfer printing technique using ribbon began to be used in Japan for printing hieroglyphs. The pioneer of this printing method was the Japanese corporation SATO, which also introduced thermal transfer printing into production. Since the 1980s, this type of printing has been used for bar coding and automatic product identification.

Thermal transfer printing of barcodes quickly became popular, as it can be applied directly at the workplace without unnecessary difficulties and fully meets the requirements of automatic identification systems.

Thermal Transfer Printing vs. Thermal Printing: Differences and Benefits of Each Type

Thermal transfer printing- a printing method in which the thermal head of the printer heats the thermal transfer ink ribbon and the ink layer from the thermal transfer ribbon is transferred to labels for thermal transfer printing (you can use a large number of materials made of paper or synthetics - this depends on the class of thermal transfer ribbon).

thermal printing is carried out in the following way: the thermal head of the printer heats the thermal label (consumable), resulting in an image. The printers used for this type of printing are called "thermal printers". Thermal printing is relevant in the following cases, if:

  • the goods on which the drawing will be applied require a short storage period (then the burnout of thermal labels is not critical);
  • products will not be exposed to high temperatures or high humidity;
  • products will not be repeatedly sorted and transported from place to place.

Thermal transfer printing using thermal transfer ribbon guarantees no fading over time, and also allows you to achieve greater resistance to abrasion and external negative influences, especially when using RESIN class thermal transfer ribbon.

Thermal transfer printing is considered more difficult and costly than other printing methods. This is due to the fact that this technology requires the presence of an additional consumable - a thermal transfer ribbon. But the use of this technology also has its advantages (depending on the class of thermal transfer ribbon):

  • the image retains color for quite a long time even with active external influences;
  • the resulting pattern has resistance to abrasion;
  • the image will be resistant to the influence of aggressive environments;
  • high speed printing;
  • high-resolution barcode printing, which makes them easier to read by a scanner;
  • printing on various materials (various types of paper – coated, uncoated, varnished; cardboard (even laminated); synthetic materials – PE, PP, PET…).

How laser transfer printing works

To print the selected image, a full-color laser printer and thermal transfer paper are used. The composition of the toner for a laser printer includes only 2% coloring pigments, the remaining 98% is plastic. Plastic during printing on thermal transfer paper melts and is transferred to paper. Then it solidifies at room temperature. The melting of the toner base under the influence of high temperature is the basis for the operation of laser thermal transfer. Thermal transfer paper for laser printing with a frozen image is applied to the intended place of the printed product and pressed with a heat press. The plastic layer of the thermal transfer paper, together with the plastic image, melts again and sticks to the fabric. That is, thermal transfer paper in this case acts like an artist's brush: it absorbs paints and transfers them to the printed material.

What is thermal transfer printing used for?

Ribbons for thermal transfer printing

In thermal transfer printing, the key role is played by the ink thermal transfer ribbon - ribbon:

  • a coloring layer is applied to a synthetic material (usually a polyester film);
  • when the print head of the printer moves, the solid dye heats up and melts;
  • during the melting process, parts of the image are transferred to the printed material.

The thermal transfer ribbon class determines the material options that can be printed on.

It, in turn, is determined by the material used for the ink layer - the most commonly used wax-based thermal transfer ribbon ( WAX), resin-based ( RESIN) or based on wax and resin ( WAX/RESIN).

Thermal transfer ribbon is a synthetic film on one side of which there is a dye that melts under the influence of elevated temperature. The reverse side is treated with a special coating that protects the printer's print head from the accumulation of static electricity.

Thermal transfer ribbon color options: blue, black, red, green, gold. If you use a ribbon of the same color, the image will be monotonous - this means that it will have a color identical to the ribbon dye. When the task is to print a multi-colored image, printing is carried out in stages: ink ribbons replace each other as many times as there are shades in the picture. The thermal transfer ribbon itself looks like a roll of polyester ribbon.

Depending on the type of thermal transfer printer used, the following two types of winding are used:

  • IN- ink layer inside (thermal transfer printers from Datamax);
  • OUT– ink layer outside (Argox, Citizen, Godex, Zebra printers).

The thermal transfer ribbon consists of the following elements:

  • Ribbon top cover. It is applied over the ink layer to make the adhesion between the ink and the printed material even better, to increase the resistance of the image to external influences.
  • Coloring layer is a hot-melt dye, the thermal transfer ribbon is heated by the printer's thermal head at different points, due to which the image is gradually transferred to the printed material; the type of thermal transfer ribbon depends on the material: WAX (wax-based), RESIN (resin-based), WAX/RESIN (based on a mixture of wax and resin).
  • Primer promotes the transfer of dye directly from the tape to the printed material. As the ribbon heats up, the primer prevents the dye from fixing to the transfer ribbon.
  • synthetic material(usually polyester film) is the basis of the thermal transfer ribbon, which ensures its integrity and strength.
  • bottom cover, which protects the printer's print head from untimely abrasion, is a special layer necessary to evenly heat the ribbon and remove static electricity.

Thermal transfer printer

This is a device for transferring images to various surfaces. First of all, the printer is needed to print all kinds of labels with a high level of wear resistance. Images can be applied to fabric, metal, plastic, thermal cardboard or thermal transfer tape. If thermal transfer printing is carried out in accordance with all the rules, then the finished image, even under the influence of negative environmental factors, will remain unchanged for three years.

A thermal transfer printer is used for applying barcodes or company logos to goods, for marking goods.

Consumables for such a printer are thermal and roll labels, thermal transfer ribbons, tags.

Printing an image from such printers is called "thermal transfer" and is carried out under the influence of the temperature of the plate and the pressure of the thermal press with a certain shutter speed.

Organization of the printing process

The thermal transfer printer applies the image in four stages. For this you need:

  1. Create a visual appearance of the label (shape and dimensions).
  2. Design a layout (you can resort to standard Windows programs or turn to specialized "label designers".
  3. Connect printer to PC via USB cable or infrared port (RS 232 interface or Wi-Fi).
  4. Start the printing process (in the "File" menu, "Print" tab).

Where is thermal transfer printing used?

The maximum time required for printing is three minutes. The image can be one- and multi-color, with various effects (glare, night glow).

As a basis for applying thermal transfer printing, the following are most often used:

  • T-shirts and T-shirts (synthetic and natural materials);
  • caps;
  • work clothes;
  • flags;
  • signboards;
  • pennants;
  • Leather Products;
  • mugs;
  • labels;
  • plastic and metal plates;
  • cups and dishes;
  • stripes;
  • sports uniform;
  • scarves, bandanas;
  • promotional underpants (there are some);
  • socks;
  • bags, backpacks;
  • puzzles - mosaic;
  • mouse pads;
  • clock - dials;
  • diplomas on metal, wood;
  • key rings;
  • nameplates.

Thermal transfer printing on T-shirts

The most commonly used thermal transfer printing on T-shirts. The technology of applying various prints on T-shirts consists of several stages. Do not forget that the picture is first applied to paper, which acts as an intermediate material, therefore, the print should be applied to paper in a mirror image, and on a T-shirt it will already be displayed correctly.

In order to get the finished image, you need to carry out several preparatory steps:

  • Using a computer program, make a layout of the future image. For us, this is a number, an inscription and, if necessary, additional images. All this is determined by the customer, based on their own wishes.
  • The image will be printed on special thermal transfer paper. In addition to the paper base, it contains a thin film on which the picture falls, and then transferred to the fabric along with it. A special cutting device (plotter) makes the shape of the film follow the contours of the picture.
  • The image on the film / paper is applied to a T-shirt / sweatshirt, etc. The fabric with a layer of paper is placed in a heat press, where, under the influence of high pressure and elevated temperature, the film is literally implanted in a certain place.
  • In the heat press, the thing is kept for some more time, after which the product cools down, and is now ready to be worn without restrictions.

Thermal transfer film printing is considered convenient because:

  • The result is an image with a high degree of clarity: the smallest or thinnest lines and elements of the image are printed and transferred without problems. This is especially true if you need to print inscriptions made in thin fonts.
  • Thermal transfer printing can be used to print on hard-to-reach areas of clothing. If it is quite easy to apply an image to a T-shirt or sweatshirt, then problems can arise with applying images to garments of a complex cut. But you won't have these problems with thermal transfer printing. Thermal transfer printing makes it possible to transfer the image even to the most inconvenient place.
  • With thermal transfer printing, you can print any number of things: make an exclusive T-shirt in a single copy or create a batch of sweatshirts for the staff of one company. The customer only needs to decide on the circulation.
  • The image applied using thermal transfer printing technology is pleasant to the touch. The pattern is embossed and pleasant to touch (whereas direct ink can be uncomfortable to touch).
  • Thermal transfer printing has a high level of image durability (especially when compared with silkscreen or batik). Such clothes need to be looked after more carefully than clothes bought in a store, but there are no complicated clauses in the care rules.
  • Thermal transfer creates a full-color drawing, its quality is close to photographic. When it comes to T-shirts with your own design, this is often the deciding factor in choosing the printing method. With the help of thermal transfer, you can transfer images or photos of any level of complexity and color palette onto fabric.

Thermal transfer printing on fabric also has limitations:

  • It is not recommended to wash printed clothes in a washing machine: despite the durability of the image, such an aggressive impact, sooner or later, can begin to destroy its structure.
  • Thermal transfer printing on colored fabrics is usually more durable than on colored items.

Thermal transfer can be called one of the most accurate, fast and permanent ways to print on any garment. For this, only a breadboard, film, plotter and heat press are needed.

Thermal transfer printing on cups

After T-shirts, this is the second most popular application for thermal transfer printing. To improve grip, it is better to take mugs with a special coating, with good adhesion. After printing, the surface of solid objects is usually coated with a polymer varnish.

Of course, despite some disadvantages, thermal transfer printing technology has shown itself well in various circumstances and will be an excellent option for those wishing to start a printing business.

Thermal stickers and thermal applications

  • accentuate corporate identity;
  • make the brand more recognizable;
  • contribute to the formation of unity in the firm;
  • create special differences from competitors;
  • bring pleasure to people of all ages, especially children.

Thermal transfer label printing

Note that any trading company in its activities cannot do without a printer for printing labels. In reality, the presence of a thermal transfer printer makes it possible to reduce the time for performing certain operations and create a truly unique type of product.

It is advisable to resort to thermal printing if you need to make a label, coupon, receipt or tickets for an event. This procedure will not take much time (and money). However, the print is sensitive to temperature and may darken with prolonged use.

Thermal transfer labels are usually applied to nylon, cardboard or self-adhesive paper. This happens quite quickly, even if the circulation is very large. Thermal transfer printing can also be used for printing on fabric labels, tags, and it will be able to withstand washing at high temperatures.

Thermal transfer printing technology is relevant for the identification of long-term storage products, as well as for the creation of outdoor labels located on products that are stored in harsh operating conditions.

In addition to thermal transfer printing, there are many ways to apply images and texts to various media and materials.

    We have recently switched to thermal transfer printing. In general, of course, compared to printing the usual heaven and earth. It looks more aesthetically pleasing and lasts longer. What I like the most is that it is waterproof. This is important for us, because the product comes into contact with water during defrosting.

    Morozov Vlad

    For me, all thermal transfer printers are basically the same. They generally do not differ in quality, only the printing speed can. It seems to me that you need to ask what consumables you will pick up, the main thing here is high-quality material and ribbon. So if you don’t find really high-quality consumables for such printers, then it’s better to consider another type of printer.

    • Denis I

      Vlad, don't tell me. There are differences in the quality of printers and very noticeable. Here is the build quality, and the reliability of the printing elements, and some kind of system glitches, the error rate. Yes, you can always save money and buy something simpler, but how long will it last you? Even with the highest quality consumables.

    Oleg

    In my work I use a thermal printer from Atol, model BP 41. I did not choose for long, I prefer Atolov products since my first cash desk. The brand guarantees the quality and indestructibility of devices, proven by practice! As for this printer, a normal working device. If you are looking for something for small print volumes, this is it. I make up to 2 thousand labels a day on it and I am quite pleased with the result.

    Mila

    I re-read the article three times, but still did not understand which type of printing is more suitable for labeling boxes in a warehouse? Now I plan to buy a printer, I don’t want to spend a lot. On the one hand, only black labels are needed, the main thing is that the device would give out a couple of thousand a day without overheating. Here, in theory, thermal printing will fit. But what about this type of printing with resistance to external influences and did not subtract. Specify please, this moment who faced.

    • Site

      Mila, warehouses often have difficult operating conditions, so it is best for you to use thermal transfer labels. With thermal transfer printing, the direct impact of the printer head on the media is excluded by placing an ink ribbon between them. They are not erased under moderate mechanical stress, do not fade under the sun's rays, the paint is not washed off under the influence of moisture. Most likely, you will need to print large quantities of barcodes, so choose printers with long yields, narrow prints and low resolutions, such as the Godex G500.

In contact with

Or labels, then you need to understand the terminology and get answers to the main questions that arise when choosing the type of printing (respectively, the label printer) or consumables.

Ordinary laser printer or specialized label printer?

  • label printer Designed to apply information that varies (varies) from label to label.
  • no need to cut the printed labels from the sheet. It saves time and paper.
  • A thermal/thermal transfer printer is able to print labels at high speeds and high resolutions that a conventional laser printer cannot.
  • Industrial-grade thermal/thermal transfer printers have a ruggedized iron body, making them suitable for use in industrial or warehouse environments.
  • support for printing most barcode symbols.
  • a large number of optional devices that improve the efficiency of the labeling process, such as a built-in cutter, printed label separator, print quality verifier, etc.

Print type. Direct thermal or thermal transfer printing. What are the differences?

  • Direct thermal. The thermal paper label is heated by the printer's thermal head to form an image.
  • Thermal transfer printing. The thermal head of the printer heats the intermediate carrier - a thermal transfer ink ribbon (ribbon). The coloring layer from the ribbon is transferred directly to the label made of paper, cardboard or synthetics.

Choosing the perfect type of print for you and your business?

The choice of printing type is dictated by the requirements for the label.

The main qualities of the label:

  • material,
  • durability,
  • resistance to sunlight, temperature changes and other weather conditions,
  • abrasion resistance,
  • resistance to aggressive environments.

Having determined the requirements for the label, you will not make a mistake in choosing the type of printing.

  • material only heat-sensitive paper (possibly with different coatings),
  • not durable (service life up to 6 months under ideal conditions),
  • not resistant to sunlight, heat,
  • not resistant to abrasion
  • not resistant to aggressive environments.

Conclusion: thermal printing is used where long-term operation of the label is not required, there are no significant temperature changes (for example, food products with a short shelf life, mail, registration badges, goods with a fast expiration date, etc.).

  • material paper, cardboard, synthetic film, plastic, etc.,
  • durable,
  • weather resistant,
  • abrasion resistant,
  • can be resistant to aggressive environments

Conclusion: thermal transfer printing for marking various equipment or goods with a long shelf life or use. By selecting the label material and the corresponding ribbon, you can achieve the necessary print qualities, such as resistance to weather conditions or aggressive media (oil, gasoline, etc.), resistance to strong heat, etc.

Thermal printer or thermal transfer printer? What is more profitable?

Direct thermal a more economical option, despite the fact that the cost of a thermal label is higher than the cost of a thermal transfer label. Thermal printing does not involve the use of additional consumables - ribbon (thermal transfer ink ribbon).

Buying a printer, working in thermal transfer mode, you get two types of printing in one device, since the printer allows you to print both with and without ribbon. The absence of a thermal transfer unit in the printer limits its capabilities to direct thermal printing only.

With direct thermal printing, the thermal head of the printer is subjected to more stress, as it is in direct contact with the label, which causes increased wear on this element. During thermal transfer printing, the thermal head works in a gentle mode, since printing occurs through an intermediate medium (ribbon).

Determining the required print resolution?

Printing at 203dpi is a solution for printing simple labels that are readable by the operator. As a rule, such resolution does not imply the printing of compact two-dimensional symbols. Printing at 305dpi is the standard resolution for logistics labels using narrow compact barcodes, 2D symbologies, including simple graphics. 609dpi printing is the ultra-compact label printing solution most commonly used in the electronics industry. Labels usually contain compact linear or two-dimensional barcodes.

Selection of the type of thermal transfer ink ribbon (ribbon) ?

There are three main types of ink ribbon: wax-based, wax-resin, and resin.

Wax are designed mainly for printing on paper labels (semi-gloss, matte).

Wax-resin for printing on paper and cardboard, in cases where it is necessary to achieve greater durability of the image.

Resin ribbons for printing on synthetic materials (labels made of polyethylene, polypropylene, textile ribbons, etc.).

Ribbon size selection?

The ink ribbon winding length is limited by the printer you are using. As a rule, compact class printers use 70-140m long ribbon, industrial class printers use ribbon up to 600m long.

When choosing a ribbon, pay attention to such an important parameter as the winding side. It can be ink layer out (OUT) or ink layer in (IN). This setting is also determined by the printer manufacturer.

The use of polymeric materials for labels

Material type

Application area

Polyethylene The material has high adhesive strength over a wide temperature range. It is used, in particular, for marking pallets that have been in open warehouses for a long time. High material resistance to solvents and chemicals. Operating temperature from -10 to +80 degrees. Celsius. The minimum temperature of the gluing surface is +5 degrees. Celsius. The material is recyclable.
Polyolefin The material provides exceptionally stable label dimensions. High resistance of the material in aqueous, slightly acidic, alkaline, saline, albumin solutions. Print speed up to 152 mm per second. Working temperature of self-adhesive labels - from -40 to +100 degrees. Celsius. The minimum temperature of the gluing surface is +5 degrees. Celsius.
PVC Used for marking on curved and uneven surfaces. The material provides high resistance to atmospheric precipitation. Print speed up to 101 mm per second. Operating temperature from -20 to +100 degrees. Celsius. The minimum temperature of the gluing surface is +5 degrees. Celsius.
Polypropylene For labels, biaxially oriented polypropylene of exceptionally high transparency is used, as well as matte white or matte color. It is used for marking in the chemical, medical and food industries. High material resistance in oils, alcohols, blood and water. Operating temperature from -20 to +100 degrees. Celsius. The minimum temperature of the gluing surface is +5 degrees. Celsius.
Polyester The material provides exceptionally high print quality and label adhesion to the surface over a wide temperature range. High material resistance in oils, alcohols, blood and water. Operating temperature from -40 to +150 degrees. Celsius. The minimum temperature of the sticking surface is 0 degrees. Celsius.
Polyamide The material provides exceptionally high print quality under extreme conditions. High material resistance in chemically aggressive environments. Operating temperature from -40 to +190 degrees. Celsius. The minimum temperature of the gluing surface is +4 degrees. Celsius.

The two most popular label printing technologies today are direct thermal and thermal transfer.

This article highlights all the differences between the two thermal label printing technologies, which can help you choose the best printing method for your labeling requirements.

Direct Thermal vs. Thermal Transfer - Quick Comparison:

Direct thermal is only suitable for labels with a short lifespan, as the period before fading is several months, depending on the temperature conditions. The cost of such printing is much lower than thermal transfer and does not require ink, toner or ribbon, but it only prints in black.

Thermal transfer printing for longer term applications requiring high print quality. Thermal transfer printing requires the use of consumables such as ink ribbons and can print in color.

The biggest difference between thermal transfer and direct thermal is that thermal transfer requires ink ribbons (ribbons) while direct thermal requires nothing more than a printer and thermal paper.

Temperature is a major component in thermal printing; thermal barcode label printers work on the following principle: the printer head heats the label with a thermally sensitive layer and this is how the image appears.
Thermal label printers, both industrial and desktop, are ideal for barcode printing as they produce accurate and high quality images.

Thermal printers are compact and are used for printing in very limited space. With direct thermal printing, there is no ink or toner consumption, and you will only need a supply of thermal label stock.

In contrast, in the thermal transfer printing process, the print head heats up an ink ribbon (ribbon) that transfers the wax or resin onto paper or film labels. Printing can be either black or color.

Thermal transfer label printing
Advantages of thermal transfer printers:

  • Provide excellent image quality and can be used for many applications
  • Accept a wider range of print media such as paper and films including polyester and polypropylene materials
  • Creates highly durable labels for labeling products stored in a variety of environments
  • Labels printed in this way are great for harsh environments and can withstand extreme temperatures, exposure to ultraviolet light, chemicals, sterilization, some solvents, and more.
  • Can print in both color and black.

Disadvantages of thermal transfer printers:

  • High operating cost
  • Replacing an ink ribbon can be a difficult and time-consuming process.
  • Takes longer to load consumables than direct thermal
  • It is always necessary to accurately select the necessary ink ribbons (ribbons)
  • Low-grade ribbons can cause excessive ink buildup, requiring more frequent cleaning
  • Disposal of used ink ribbons can be considered as an unsustainable process.

Applications for thermal transfer labels:

  • Delivery and logistics, mailing, parcel identification;
  • Archives, tracking files and folders;
  • Inventory identification;
  • retail labels,
  • Laboratories, storage in freezers.

Thermal label printing
Benefits of direct thermal printers:

  • The cost of printing is less than inkjet, laser, and thermal transfer printers
  • No need for ink ribbon, ink or toner
  • Durable and easy to use
  • More environmentally friendly as you don't have to dispose of used ink ribbons.

Disadvantages of direct thermal printers:

  • Images on thermal labels may fade over time
  • Overheating of the material from which the labels are made can lead to darkening of the labels, while the information printed on them becomes unreadable.
  • The label smudges if rubbed well.
  • Limited choice of label materials
  • Causes more printhead wear, so more frequent printhead replacement is expected
  • Black and white printing only

Applications for direct thermal labels:

  • shipping labels,
  • retail labels,
  • Inventory identification;
  • receipts,
  • Labels coupons, event tickets;
  • parking tickets
  • Passes and other short-term markings.
