Many friends don't know how to choose thermal label paper to be able to choose the right product for them. Next, Putie Technology will give you a brief introduction to what you need to pay attention to before purchasing thermal label paper. Simply answer some caveats;
Before buying thermal label paper, we can start with the appearance of the product and some small methods of testing;
1. Appearance: Before purchasing thermal paper, you can carefully check the appearance of the product. From the color, you can distinguish the quality of its protective coating and thermal coating to a certain extent. If the surface of the paper is too white, it means that the protective coating and thermal coating of the paper are unreasonable, and it is likely that too much phosphor is added. If the paper is slightly greenish, the product quality is good, and if the paper looks smooth and flat, it means that the thermal coating is relatively uniform, otherwise, it means that the coating of the paper is uneven, and the uneven coating may affect the final printing. Effect.
2. Contrast in sunlight exposure: The method of sunlight exposure is very simple, as long as two different sheets of paper are printed, painted with the same highlighter and placed in the sun, eventually they will all turn black, check the two sheets of paper. Blackening speed, the longer it takes to turn black, it means that the thermal paper can be stored for a longer time and has a longer service life.
3. Use fire to bake: You can use a lighter to slowly heat the back of the paper, and the color of the paper will change with heating. If the final color is brown, it means that the thermal formula is not reasonable, and the storage time may be shorter. Shorter, if fine streaks or scattered patches of color are visible on the paper, the coating is uneven. On the contrary, the thermal paper with better quality will eventually appear black-green after heating, with uniform color blocks, and the color will gradually become lighter when viewed from the center of the heating to the surroundings.
