What is the impact of the coating amount of PET thermosensitive silver paper on the printing effect?

The coating amount of PET thermosensitive silver paper has a significant impact on the printing effect. The following is a specific analysis:

1、 The impact of coating amount on printing clarity

The amount of coating directly affects the thickness of the thermosensitive coating on the PET substrate. An appropriate amount of coating can ensure even distribution of the thermosensitive coating, resulting in clear images or text during printing. If the coating amount is insufficient, the thermal sensitive coating may be too thin, resulting in poor printing effects such as blurry handwriting and insufficient color saturation. On the contrary, if the coating amount is too large, the thermal sensitive coating may be too thick, which not only increases costs, but also may affect the normal contact of the print head, thereby affecting the printing clarity.

2、 The impact of coating amount on printing speed

The coating amount can also affect the printing speed. In the thermal printing process, the print head needs to heat the thermal coating to make it color. If the coating amount is too large, the print head requires more energy and time to heat the coating, resulting in a decrease in printing speed. On the contrary, an appropriate amount of coating can ensure that the print head can quickly and effectively heat the coating, thereby improving printing speed.

3、 The impact of coating amount on durability

The coating amount also has a certain impact on the durability of PET thermosensitive silver paper. An appropriate amount of coating can ensure that the thermosensitive coating has sufficient thickness and strength to resist external environmental erosion and wear. If the coating amount is insufficient, the thermal sensitive coating may be more susceptible to damage, causing the printed content to fade or blur. However, excessive coating may also lead to a decrease in the overall strength of the paper, making it prone to tearing or damage.

4、 The impact of coating amount on cost

The amount of coating directly affects production costs. Excessive coating amount will increase the usage of raw materials, thereby increasing production costs. An appropriate amount of coating can reduce production costs and enhance product competitiveness while ensuring printing quality.

In summary, the coating amount of PET thermosensitive silver paper has a significant impact on the printing effect. To ensure the best printing effect, it is necessary to choose the appropriate coating amount based on specific printing requirements and paper specifications. At the same time, the uniformity and stability of the coating amount should be strictly controlled during the production process to ensure the consistency and reliability of product quality.
