Thermal paper is a kind of paper with a special coating that enables printing without ink. When heat is applied to the coating using a thermal paper printer, the result is a, strong and clear image as well without having the need to use ink or ribbons.

The thermal paper offers fast, high-resolution, and reliable images. The technology of thermal paper is widely used in various industries.

Specific areas, such as medical care, depend on high-quality images. The images are produced by thermal printing. The thermal printing is used for important, high-tech prints requiring accuracies, such as ultrasound impressions, ECGs and prescription labels.

Retailers also utilise thermal paper for point-of-sale uses such as gas stations, grocery stores and ATMs to assure speedy and precise service. 

Lottery systems, ticket agencies, Warehousing and other industries requiring high-volume, perfect printing depend on thermal paper.Thermal Paper Facts.

If you wonder how the thermal paper is produced, you can read the following information from KPL International Limited.

The paper surface is coated with a solid mix of a dye and an appropriate matrix. The coating consists of chemical in 4 different types:

The dye can change colours between two chemical forms, one of which is colourless. Generally, in thermal paper, the dyes used are fluoran dyes or triaryl methane phthalide dyes or Crystal Violet Lactone dyes.

Sensitizers are also included to the surface of the paper to maximise the dyeing temperature and to aid the leuco-developers and dyes mixing during melting.

Basically, developers are organic acids that are also fused with leuco dyes to give more colour, such as sulfonylureas, phenols, and also zinc salts of substituted salicylic acids.

Stabilizers are included to stabilise the layer or glass produced by the leuco dye, sensitiser and developer, or the glass, and to avoid the colours from going back to their original colourless crystalline form when put under humid or hot conditions.

The following is the explanation about the work of thermal paper according to POS Supply Solution.

For the thermal paper to produce image, it requires a static heat source like a thermal print head. This is achieved by a series of very fine spots that are heated and cooled while the paper is being conveyed through the print head by a step motor.

The image density can be calculated by the image result like how dark the image is when it receives different energy levels. The density or darkness is calculated with a densitometer, and the paper must have a complete image or reach a density reading of 1.2 to achieve the best image life for such grade.

Paper or synthetic base sheet that are available in various calipers which are coated to the sheet.

Used as a base to seal the substrate and give a surface to which the thermal coating adheres.

This is the thermal coating. It is originally a Leuco dye-based chemical system which produces the image when the heat is used.

A clear PVA layer that seals the active layer and gives environmental resistance and greater image life normally used in stressed and harsh environments.

This coating is used to the back of some papers. However, it is frequently used as an antistatic coating on synthetic base sheets such as polypropylene-based thermal grades that can produce or diffuse static electricity and burn electronic components.

According to early twentieth-century scientists, products containing asbestos were the best insulation to guard keep save your homes from burns, fires, or other high-temperature risks. Thermal paper was one such product that was extensively employed for this purpose. The paper was used to wrap pipes or machine parts to keep them save from extreme temperatures

The asbestos contained in the thermal paper are fully intact unless the paper product is too old or damaged or changed. However, the thermal paper often had to be cut to insulate it, exposing the worker to asbestos fibres floating in the air. The same exposure may occur if the paper is torn or damaged, for instance in an older building the renovation. Therefore, when dealing with asbestos removal during renovation you should use a professional service asbestoswatchperth.com.au is the place to visit when you need information about asbestos removal.
