The distinguish method of thermal paper _ printing devices
Thermal paper is the thermal paper as raw material through simple processing production of a volume type printing paper. Also known as: volume thermal cash register paper, thermal printing paper. Thermal paper mainly USES in the cashier system thermal printers, thermal paper has hair color uniformity, smoothness is good, high whiteness, long shelf life without printing consumables, in use process without carbon belt, ribbon, or the cartridge, therefore in the cashier system thermal paper to replace the ordinary paper. Thermal paper is now widely used in supermarkets, hotels, Banks, telecommunications, medical and other industries. Paper thermal printing paper generally divided into three layers, the bottom of base paper, the 2nd is thermal coating, the third layer of protective layer, thermal coating as a kind of special capsule, heat-sensitive color. Mainly for affecting the quality of its thermal coating or coating. Paper, thermal paper, the characteristics of the choose and buy method: thermal paper is specially used for thermal printers and thermal fax paper, its quality directly affect the print quality and save time, and even affect the service life of the printers and fax machines. Thermal paper currently on the market the good and bad are intermingled, the country and has not issued national standard, many users don't know how to identify the quality of thermal paper, it is for many businesses keep inferior thermal paper provides convenient, causes losses to the user, light save time shorten, blur, heavy damage to the printer. Top electronics here tell you how to identify the pros and cons of thermal paper, so as not to fall for it again. Store cash register paper thermal printing paper generally divided into three layers, the bottom of paper base, the 2nd is thermal coating, the third layer of protective layer, mainly for affecting the quality of its thermal coating or coating, if uneven thermal paper coating, will lead to print, in some places darker, some local color shallow, significantly lower print quality, if thermal coating chemical formula is not reasonable, will cause the printing paper to save time is short. Good printing paper printing can be stored (after Under the condition of normal temperature, avoid direct sunlight) 5 years, are now more long-term thermal paper can save ten years, but if the thermal coating formula is not reasonable, may be only a few months. The ink paper protective coating for print after the save time is also key. It absorbs some of chemical reaction that generates heat sensitive coating light, slow the deterioration of paper, and the thermal sensor can protect the printer is not damaged, but if the protective coating is not even, not only can greatly reduce the thermal protection coating, even in the printing process will appear tiny particles protective coating fall off, friction printer thermal element, lead to the damage of print heat sensitive components. Thermal paper quality to identify 1, appearance: if the paper is very white, to explain the protective coating of paper and thermal coating is unreasonable, added too much phosphors, a good paper should be slightly green. Paper smoothness is not high or look uneven, paper coating is not even, if the paper looks the reflected light is very strong, is added too much phosphor powder, the quality is not very good. 2, fire with fire: baking method is simple, with a lighter heating on the back of the paper, if after heating, the paper is now out of brown color and specification thermal formula is not very reasonable, save the time may be more short, if the paper is on the black part with thin stripes or uneven color piece, uneven coating. Good quality paper after heating for the dark green is ( With a little green) And uniform color piece, from the center to color become weak gradually. 3, sunlight contrast identification: will print out the paper with fluorescent pen after daub on the sun, This can accelerate the thermal coating light reaction) , fastest turn black, what kind of paper that can save the shorter the time.
