how to identify thermal label paper?
thermal printing paper generally divided into three layers: the bottom for thermal coating for paper base, the second floor, the third layer of protective layer, mainly affecting the quality of thermal printing paper for thermal coating or coating.
thermosensitive coating: if uneven thermal paper coating, can lead to print label color shades, significantly lower quality; If thermal coating chemical formula is not reasonable, can affect the thermal print labels save time;
protective coating, protective coating can absorb part of the chemical reaction that generates heat sensitive coating of light, slow the deterioration of paper, and the thermal sensor can protect the printer is not damaged. 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.
heat-sensitive paper labels on the market at present the good and bad are intermingled, many users don't know how to identify the quality of the thermal paper. Editor is here and you talk about how to identify thermal label paper.
1, appearance: if the paper is very white, shows that the protective coating and thermal coating of paper is unreasonable, added too much phosphors, a good paper should be slightly green; If the paper is bright and clean degree is not high or look uneven, illustrate the paper coating is not uniform; If the paper looks the reflected light is very strong, is added too much phosphors, the quality is not very good.
2, fire: use lighter heating on the back of the paper, if the paper is now out of color to brown after heating, thermal formula is not reasonable, print the handwriting save time may be shorter; 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.
