Thermal Paper Introduction
Thermal paper is generally divided into three layers, the bottom is paper-based, the second layer is heat-sensitive coating, the third layer is a protective layer that primarily affects their quality of thermal coating or protective layer，
If uneven coating of thermal paper, will lead to printing, color depth in some places, some places light color, print quality significantly reduced, if the thermal coating chemical formula is unreasonable, will lead the paper to save time becomes very short, a good paper after printing can be saved (at room temperature, out of direct sunlight conditions) five years, and now you can save more long-term thermal paper for 10 years, but if the thermal coating formulations unreasonable could only be saved for months.
Protective coating for the preservation of printed time is very critical, it can absorb some of the heat-sensitive coating resulting chemical reaction produces light, slow deterioration of paper, and can protect the printer's thermal components from damage, but if the protective coating uniform layer, will not only greatly reduce the protection of heat-sensitive coating, even in the printing process will be small particles off the protective coating, a thermal printer friction element, leading to printing thermal damage to components.
Differential thermal paper has the following advantages and disadvantages of several ways:
1、Appearance: If the paper is very white, indicating that the protective coating and thermal paper coating unreasonable, add too much phosphor, the paper should be slightly better pan. Paper finish is not high or appear uneven, indicating uneven coating of paper, if the paper looks strong reflected light, but also added a plethora of phosphor, the quality is not very good.
2、Roasted: with fire method is also very simple, with a lighter in the back of the paper heated, if heated, the paper emerges the color is brown, indicating that the thermal formulation is not reasonable, saving time may be relatively short, if the paper some have small black streaks or uneven color, indicating uneven coating. Good quality paper after heating is due to the black and green (with a little green), and the color evenly from the center to the surrounding color gradually fades.
3、Sunlight contrast identification: the printed paper with a highlighter pen smear and placed out in the sun (this can accelerate the heat-sensitive coating reacts to light), what kind of paper the fastest black, indicating that the shorter the time can be saved.
