The Purchase Of Thermal Paper

Thermal paper is specially used for thermal printers and thermal fax machine printing paper, its quality directly affects the printing quality and storage time, and even affects the service life of printers and fax machines. The thermal paper on the market is uneven, and the country has not yet issued a national standard, and many users are not clear about how to identify the quality of thermal paper, which provides convenience for many businesses to produce and sell inferior thermal paper, causing losses for users, and the light storage time becomes shorter, the handwriting is blurred, and the heavy damage to the printer. This article tells you how to identify the advantages and disadvantages of thermal paper so as not to be fooled again. Thermal printing paper is generally divided into three layers, the bottom layer is the paper base, the second layer is the thermal coating, the third layer is the protective layer, and the main impact on its quality is the thermal coating or protective layer.

If the coating of the thermal paper is uneven, it will lead to printing, some places are dark, some places are light, and the printing quality is significantly reduced, if the chemical formula of the thermal coating is unreasonable, it will cause the printing paper to be stored for a very short time, and the good printing paper can be stored for 5 years after printing (at room temperature and under the condition of avoiding direct sunlight), and there is a long-lasting thermal paper that can be stored for 10 years, but if the formula of the thermal coating is not reasonable, it may only be stored for a few months.

The protective coating is also critical for the storage time after printing, it can absorb a part of the light that causes the chemical reaction of the thermal coating, slow down the deterioration of the printing paper, and can protect the thermal element of the printer from damage, but if the protective coating is uneven, it will not only greatly reduce the protection of the thermal coating, but even the fine particles of the protective coating will fall off during the printing process, rubbing the thermal element of the printer, resulting in damage to the thermal element of the printing.

Thermal paper is generally sold in the form of rolls, generally 80mm× Φ60mm, 57mm× Φ50mm and other specifications are the most common, the front number indicates the width of the paper roll, the back is the diameter, the width of the general error of 1, 2mm has no impact on the use, because the printer generally can not print on the edge, but the diameter of the paper roll has a greater impact on the buyer, because the total length of the paper rolled by the paper roll is directly related to the cost performance of the roll of paper, if the diameter is indicated is 60mm, but the actual is only 58mmThe length of a roll of paper will be reduced by about 1 meter (the specific reduction depends on the thickness of the paper), but the thermal paper rolls sold on the market are generally marked with X0, and the actual diameter is often less than X0. It should also be noted that the diameter of the core in the middle of a roll of paper, some businesses will also do tricks and feet on the core, choose a larger core, and the length of the paper will be shortened a lot. Simple way, the buyer can bring a small ruler to measure whether the diameter is consistent with the diameter marked in the box, and the diameter of the die also needs to be paid attention to, so as not to cause the buyer to suffer a loss due to the shortage of unscrupulous merchants.
