Thermal Label Paper

Thermal label paper is by the high heat-sensitive thermal coating of paper, the high sensitivity of the surface material applicable to low voltage print head, so the small print head wear. Thermal paper is devoted to electronic, said the cash register of a hot fight on paper, thermal paper tests the easiest way: on paper with a fingernail across the force, will leave a black scratch. Thermal Paper for the cold storage, refrigerator shelves and so signed on the size of most of its fixed 40mmX60mm standards.
Thermal label paper selection and quality of the identification
Thermal paper is devoted to thermal printers and thermal printing paper fax machines, its quality directly affects print quality and save time, and even affected the life of the printer and fax machine.
Currently on the market mixed thermal label paper, the state has not promulgated national standard, many users do not know how to distinguish the quality of thermal paper, which for many businesses keep the system provides a convenient low-grade thermal paper, causing losses for the user, Light is the thermal printing paper storage time shorter, illegible, heavy damage to printer. The following thermal paper to tell you how to identify the strengths and weaknesses, so as not to be taken in again.
Thermal printing paper is generally divided into three layers, the bottom of the paper-based, and the second layer is heat-sensitive coating, the third layer protective layer, the main impact of the quality of thermal printing paper for the thermal coating or protective layer, if Thermal paper coating uneven printing result, some local color deep in some places light in color, print quality and significantly reduced, if the chemical formula unreasonable thermal coating will lead to saving time, thermal paper very short, good printing paper after printing can be saved (at room temperature, avoid direct sunlight conditions) 5-year, and now you can save more 10 years of long-term thermal paper, thermal coating formulations, but if not reasonable thermal paper may only save a few months.
Protective coating for the preservation of time after printing is also critical, it can result in thermal coating absorb part of the chemical reaction of light, slow degeneration of printing paper, thermal printer, and to protect components from damage, but if the protection coating layer of uniform, not only will greatly reduce thermal protection coating, and even appears in the print process of protective coating of small particles fall off the printer's thermal components of friction, resulting in damage to the printed heat-sensitive components.
Differential thermal label paper has the following pros and cons of several ways:
1, Appearance: If the paper is white, indicating the protective coating and heat-sensitive paper coating unreasonable, excessive phosphor added, should be slightly better pan-green paper. Paper finish is not high or looks uneven, indicating uneven coating of paper, if the paper looks very strong reflected light, the phosphor is added too much, quality is not good.  
2, broiled: with fire method is simple, with a lighter in the paper on the back of heating, if heating, paper stand out for the brown color, indicating less thermal reasonable formula to save time may be short, if part of the paper on a small black stripes or color blocks uneven, indicating uneven coating. Good quality paper in black after heating because of the green (with a little green), and blocks of color uniformity, from the center of the color gradually fades to four weeks.
3 Identification of sunlight contrast: will print out on paper with a highlighter smear sun drying (this can speed up the response to light thermal coating), the fastest black paper which shows that the more time can be saved Short.
