Thermal paper is different from ordinary paper? _ printing equipment

thermal paper is a kind of special printing consumables, so we use in our daily life it what is the difference between the general paper? Top for you to do a professional analysis.

the principle of thermal paper is on the general paper base powder coated particles, composition is colorless dye phenol or other acidic substances, with thin film apart, under the condition of heat, melt film, powder mixed chromogenic reaction. Color of handwriting on thermal paper is not stable, easy to fade, it is difficult to identify the file content.

on the thermal paper is specially used for thermal printers and thermal fax paper, its quality directly affect the print quality and preservation time, and even affect the service life of the printers and fax machines. At that time, the good and bad are intermingled of market of thermal paper, the state has not issued national standard, many users don't know how to distinguish the quality of thermal paper, it is for many businesses keep inferior thermal paper supplies the bento, for the user to lose, light storage time shorten, handwriting confused, heavy damage to the printer. Thermal printer paper generally divided into three layers, the bottom of base paper, the 2nd is thermal coating, the third layer of protective layer, first for affecting the quality of its thermal coating or coating; Where is the difference between thermal paper and ordinary paper?

if uneven thermal paper coating, printing, cause, in some places darker in some places the color shallow, significantly lower print quality, if thermal coating chemical formula is not reasonable, cause printing paper keeping time very short, can keep after good printing paper printing ( Under the condition of normal temperature, avoid direct sunlight) Five years, and now have more long-term thermal paper can keep ten years, but if the thermal coating formula is not reasonable, can only keep a few months.

the difference between thermal paper and ordinary paper in where? Protective coating on print after the storage time is also very crucial, it absorbs the light some chemical reaction causing thermal coating attack, reduce the metamorphosis of printing paper, and can protect the thermal element is not affected by the damage of the printer but if protective coating is not even, not only can greatly reduce the thermal protection coating, even in the printing process will appear in the protective coating of fine particles falling, resistance temperature sensor for the printer, causing harm to print heat sensitive components.
