Mastering Thermal Paper Production: From Coating to Slitting & Flexo Printing Techniques

Thermal paper is divided into three layers: the bottom paper base, the middle thermal coating layer, and the protective layer.

It is mainly used in POS applications (such as supermarkets, shops, banks, and courier services), as well as in industries such as labeling, ticketing, and gambling.

Thermal paper is a type of printing paper used in specialized printers and fax machines.

The quality of thermal paper directly affects the quality of the printed output and the longevity of the paper, which in turn can affect the lifespan of the printer.

The uniqueness of thermal paper lies in the special structure of its coating.

Thermal paper typically undergoes two coating processes on the base paper.

The outermost layer is the color-developing layer, responsible for the thermal paper’s color development.

When the paper passes through a heated print head, the color-developing agents and color developers in the color-developing layer react to heat, resulting in the corresponding patterns or text appearing on the paper.

Uneven coating of the color-developing layer can lead to variations in color depth during printing, significantly reducing print quality.

Between the base paper and the color-developing layer lies the base coating layer, which has very low thermal conductivity.

This layer effectively reduces heat loss during printing, ensuring that the color-developing layer reaches the color-developing temperature range uniformly.

When thermal paper is heated, colorless dyes react with color developers to produce color.

Therefore, when using thermal paper to receive signals for printing on fax machines or directly printing with thermal printers, images and text appear.

Since there are many varieties of colorless dyes used, the resulting ink colors vary, including blue, magenta, black, etc. Thermal paper is commonly used in lottery tickets.

The production principle of thermal paper involves applying a layer of “thermal coating” on a high-quality paper base.

The main thermal components in the thermal paper coating are typically two types: colorless dyes, also known as latent color dyes, and color developers. This type of thermal paper is also known as two-component chemical thermal recording paper.

The main components of the thermal paper coating include trace amounts of colorless dye fluorescent compounds.

  1. Color developers, which account for less than 20%, commonly include bisphenol A and hydroxybenzoate esters.
  2. Sensitizer, accounting for less than 10%, such as benzene sulfonamide compounds.
  3. Fillers, accounting for less than 50%, commonly calcium carbonate (particles), which increase the opacity of the paper and enhance the contrast between imaging and background.
  4. Adhesives, accounting for less than 10%, such as polyvinyl acetate, which provide the coating with good surface strength and printing performance, while forming a colloid protective film between the dye and color developer to isolate them to prevent premature reactions.
  5. Stabilizers, accounting for a few percent, such as phenolphthalein diphenylsulfone; and lubricants, accounting for a few percent, typically wax-like substances used to prevent contamination of the thermal head.

Standard thermal paper ink tends to have unstable color development and is prone to fading, making it unsuitable for long-term preservation. High-quality thermal paper can be preserved for approximately 30 years.

Now, let’s delve into the general thermal paper production process.


The coating process of thermal paper involves applying thermal coating onto the surface of the paper.

This step is crucial in the production of thermal paper and requires specialized coating equipment.

Thermal coating consists of various components, including color developers, sensitizers, and adhesives.

During coating, it is essential to control the coating amount and uniformity to ensure the quality of the thermal paper.

After coating, the thermal paper needs to undergo a drying process to remove moisture and solvents from the paper’s surface.

Drying must be carried out in a constant temperature and humidity environment to prevent adverse effects on the performance of the thermal coating.

After drying, the thermal paper should remain flat and free of wrinkles.


The dried thermal paper is then subjected to a cutting process to produce the desired width and length.

During cutting, it is essential to ensure clean cuts without jagged edges to improve the effectiveness and lifespan of the thermal paper.

To meet market demands, thermal paper rolls is typically used in small printers, so subsequent processing techniques include slitting rewinding and flexographic printing.

Subsequent Processing Techniques:

Slitting Rewinding:

Thermal paper is generally sold in roll form, with common specifications such as 80mm×Φ60mm and 57mm×Φ50mm.

The first number denotes the width of the paper roll, while the second represents the diameter.

Minor discrepancies in width, within 1 or 2mm, usually do not affect usage significantly, as printers typically cannot print to the very edge of the paper.

However, the diameter of the paper roll can have a more significant impact on the buyer’s choice.

If purchasing thermal paper rolls directly from the paper mill, they typically come in widths of 700-1400mm.

To cut large rolls into smaller ones, you would need an appropriate slitting machine.

Jota Machinery has over 20 years of experience in selling thermal paper slitting machine, which are available in economic, semi-automatic, fully automatic, and coreless thermal paper roll-specific versions.

These machines can handle roll widths of 700/900/1400mm.

Flexographic Printing:

The water-based ink used in flexographic printing is a critical material that directly affects the production efficiency and practical effects of printed products.

Nowadays, there are numerous brands of water-based ink, with significant differences in quality and price.

It is essential for printers to select water-based ink reasonably, which is a fundamental skill for printing professionals.

paper roll business

Given the wide range of applications for printing materials, it is crucial to select suitable water-based ink that matches the printing substrate.

The types of water-based ink used for absorbent and non-absorbent materials are entirely different.

Even for absorbent materials, the selection of water-based ink should consider the specific requirements of the printed product, as different materials have different surface properties.

When selecting water-based ink, practical considerations include printing suitability, viscosity, adhesion, drying properties, water resistance, abrasion resistance, acid and alkali resistance, among others.

For example, beer labels must withstand friction during labeling, immersion in ice water during sales, and separation during bottle washing; pressure-sensitive labels require resistance to friction on packaging assembly lines; film printing requires adhesion and peel strength, among other factors, all of which impose different requirements on water-based ink.

Therefore, when selecting water-based ink, attention should be paid to the following points:

  1. Differentiate between the types and qualities of printing substrates;
  2. Understand the practical requirements of printed products;
  3. Custom-order specialty inks from manufacturers or assign specific personnel from printing factories;
  4. Stabilize the pH value and viscosity of water-based ink;
  5. Control the amount of additives;
  6. Do not mix water-based inks from different brands.

Ceramic Anilox Roller:

The ceramic anilox roller is considered the “heart” of the flexographic printer, highlighting its importance.

The ceramic anilox roller, paired with the doctor blade, accurately and stably transfers water-based ink.

Therefore, the ceramic anilox roller is also known as a metering roller or volume roller, ensuring that the ink layer remains within the selected BCM (anilox ink transfer volume) range throughout ink transfer.

The principle of “no color deviation” in flexographic products relies on this.

Commonly used ceramic anilox rollers have the following line counts:

  • For solids: 250-400 lines per inch
  • For text and line work: 400-600 lines per inch
  • For screens: 550-800 lines per inch (suitable for 133-150 screen mesh), 700-1000 lines per inch (suitable for 175 screen mesh)

When selecting an anilox roller for a specific color printing plate to meet ink transfer requirements, not only should the line count be considered, but also the comparison of BCM values within the same line count range.

This ensures a reasonable selection.

Generally, it is better to equip multiple anilox rollers to accommodate variations in ink volume requirements for different products.

Mixing ink colors to compromise should be avoided, as it may result in suboptimal ink volume and ink layer thickness, as well as difficulty in achieving the desired color hue.

This approach not only wastes time and ink but also leads to unsatisfactory print quality.

Thus, the losses incurred far exceed the cost of purchasing additional ceramic anilox rollers.

Doctor Blade

The doctor blade, together with the ceramic anilox roller, forms the ink transfer system.

Modern flexographic printers are equipped with insert-type reverse doctor blades, which are convenient to operate and provide excellent ink transfer.

Doctor blade materials include steel and plastic, with the blade edge ground to an angle for efficient ink removal.

The pressure adjustment of the doctor blade should ensure that any excess ink on the surface of the anilox roller is completely removed, without applying excessive pressure that could damage the ceramic anilox roller.

Worn doctor blade blades should be replaced promptly to ensure ink transfer quality.

Above is the whole introduction for mastering the thermal paper production: from coating to slitting & flexo printing techniques.
