For many customers to identify the quality of thermal paper
may only focus on the price and feel of paper, and do not know how to correctly identify the thermal paper, today we will give you a popular, thermal paper identification method, in the end how to identify the quality of your thermal paper?
First of all from the appearance, if the paper is very white, that paper protection coating and thermal coating is unreasonable, added too much phosphor.
Good quality thermal paper should be slightly green. If the paper smoothness is not high or looks uneven, that thermal paper coating is not uniform, if the thermal paper seems to reflect light is strong, but also added too much phosphor powder, the quality is not good, there will be too much paper scraps, too much dust.
Secondly we can use the method of fire, roast method is simple, with a lighter heating on the back of the paper, if after heating, 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 black, and some with small stripes or uneven color piece, uneven coating. Better quality paper in the heat should be black green (with a little green), and color block uniform, color from the center to the surrounding gradually light, this kind of thermal paper is color good with long storage time.
Thirdly, we can use the method of comparison and identification of sunlight exposure: the paper printed with a fluorescent pen daub in the sun (this can speed up the reaction of the thermal coating to the light), which paper is the fastest to black, indicating that the shorter the preservation time.
