Thermal label paper is coated by a high heat-sensitive thermal paper material, highly sensitive surface material suitable low voltage print head, and thus minimal wear on the print head. Thermal paper is devoted to electronic scales, cash registers inside a hot beat paper, thermal paper tests the easiest way: with a nail firmly on the paper across, will leave a black scratches. Thermal paper for refrigerator, freezer, etc. shelves sign, the size of most fixed 40mmX60mm standards.
Optional thermal paper label
Thermal paper is designed for thermal printers and thermal fax paper, and its quality directly affects print quality and save time, and even affect the life of the printer, and fax machines.
Currently on the market varies greatly thermal label paper, the state has not yet introduced GB, many users do not know how to identify the quality of thermal paper, which for many businesses to keep the system provides a convenient low-quality thermal paper, resulting in losses for the user, lightweight thermal paper storage time is shorter, illegible, heavy damage to the printer. Here to tell you how to identify the advantages and disadvantages of thermal paper, so as not to be fooled again.
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, mainly affecting the quality of thermal paper for 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 to thermal paper to save time 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 up to 10 more years of long-term thermal paper, but not if the thermal coating formulations reasonable thermal paper may only save a few 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.
Identification of thermal paper label
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, broiled: 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 part of the paper with tiny 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 more time can be saved shorter. |
