Thermal Paper Protective Coating

Thermal Paper Protective coating

Thermal paper is designed for thermal printers and thermal fax machine printing paper, the quality of its direct impact on print quality and save time, and even affect the printer and fax machine life. Currently on the market thermal paper varies greatly, the state has not yet issued a national standard, many users are not sure how to identify the quality of thermal paper, which for many businesses to control the inferior thermal paper provides a convenience for users to cause damage to light The shorter the save time, blurred, heavy damage to the printer. This article tells you how to identify the pros and cons of thermal paper, so as not to be fooled again. Thermal printing paper is generally divided into three layers, the bottom of the paper-based, the second layer of heat-sensitive coating, the third layer for the protective layer, the main impact on the quality of the thermal coating or protective layer,

Uneven coating of thermal paper can lead to darker colors in some areas of printing, lighter colors in some areas, and significantly lower print quality. If the chemical formulation of the thermal coating is not reasonable, it can result in a change in the retention time of the printing paper Very short, good print paper can be stored after printing (at room temperature, to avoid direct sunlight conditions) 5 years, and now more can save 10 years of long-term thermal paper, but if the formula is not reasonable thermal coating , May only save a few months.

The protective coating is also critical for the shelf life after printing, as it absorbs a portion of the light that causes the chemical reaction of the thermal coating, slows the deterioration of the printing paper, and protects the thermal elements of the printer from damage, but if the protective coating The unevenness of the layer not only greatly reduces the protection of the thermal coating, and even small particles that may have a protective coating during printing come off, rubbing the thermal elements of the printer, resulting in damage to the printed thermal elements.

Thermal paper is generally sold in the form of rolls, usually 80mm × Φ60mm, 57mm × Φ50mm and other specifications are the most common, the front of the paper said the width of the roll, the back is the diameter, the width of the general error of 1, 2mm has no effect on the use because Printers generally do not print on the edges, but the diameter of the roll has a greater impact on the purchaser because the total length of roll paper is directly related to the cost performance of the roll. If the diameter is 60 mm, the actual Only 58mm, the length of a roll of paper will be reduced by about 1 meter (depending on the specific reduction depends on the thickness of the paper), but the market for thermal rolls are generally marked X0, the actual diameter is often less than X0. There is also a need to pay attention to a roll of paper in the middle of the diameter of a die, some businesses will die on the die again, the choice of larger die, the length of the paper has to be shortened a lot. Simple way buyers can take a small ruler diameter and the diameter of the box labeled diameter is consistent, the die diameter also need to pay attention to avoid the unscrupulous merchants Quejue short lead buyers to suffer losses.
