The factors that affect the thermal performance of PET matte silver thermal paper mainly include the following aspects:
1、 Thermal sensitive coating formula and uniformity
Chemical formula: The chemical formula of the thermosensitive coating is the key factor determining its thermosensitive performance. The proportion and types of colorless dyes, colorants, sensitizers, stabilizers, and other components in the formula directly affect the printing effect, storage time, and weather resistance of thermal paper.
Coating uniformity: The uniformity of thermal sensitive coatings has a direct impact on the printing effect. If the coating is uneven, it can result in uneven color depth during printing, affecting overall aesthetics and readability.
2、 Protect the quality of the coating
Protective performance: The protective coating can absorb some of the light that causes chemical reactions in the thermosensitive coating, slowing down the deterioration of the thermosensitive paper and extending its service life. At the same time, it can also protect the thermal sensitive components of the printer from damage.
Coating uniformity and adhesion: The uniformity and adhesion of the protective coating are equally important. If the coating is uneven or has poor adhesion, it not only cannot effectively protect the thermal sensitive coating, but also may cause small particles to fall off during the printing process, further damaging the thermal sensitive components of the printer.
3、 Quality of paper substrate
PET material properties: As the substrate of matte silver thermal paper, PET's own properties also have a certain impact on its thermal performance. High quality PET materials have good flatness, strength, and weather resistance, which can provide stable support for thermal sensitive coatings.
Surface treatment of substrate: The treatment of the substrate surface can also affect the adhesion and printing effect of the thermal sensitive coating. If the surface treatment of the substrate is improper, it may lead to problems such as poor coating adhesion and unclear printing.
4、 Storage and usage conditions
Temperature and humidity: PET matte silver thermal paper needs to avoid prolonged exposure to high temperature and high humidity environments during storage and use. Such an environment will accelerate the chemical reaction of thermal sensitive coatings, resulting in poor printing performance and shortened storage time.
Lighting conditions: Long term exposure to light can also accelerate the deterioration of thermal paper. Therefore, during storage and use, direct sunlight or strong light sources should be avoided as much as possible.
5、 Printer parameters and print head status
Printer parameter settings: The parameter settings of the printer (such as print density, print speed, etc.) will directly affect the printing effect. Reasonable parameter settings can ensure that the printed images and text are clear and durable.
Print head status: The cleanliness and wear of the print head can also affect the printing effect. Regular cleaning of print heads and replacement of severely worn ones can ensure the stability of print quality.
In summary, there are multiple factors that affect the thermal performance of PET matte silver thermal paper, including the formulation and uniformity of the thermal coating, the quality of the protective coating, the quality of the paper substrate, storage and use conditions, as well as printer parameters and print head status. When selecting and using PET matte silver thermal paper, it is necessary to consider these factors comprehensively to ensure the best printing effect and service life.
