What impact does the surface smoothness of BOPP thermal sensitive synthetic paper have on printing?

The surface smoothness of BOPP thermal sensitive synthetic paper has a significant impact on the printing effect. The following is a detailed analysis of the relationship between the surface smoothness and printing effect of BOPP thermal sensitive synthetic paper:

1、 The influence of surface smoothness on printing clarity

The surface smoothness of BOPP thermal sensitive synthetic paper is an indicator of the smoothness of the paper surface, which reflects the smoothness of the paper at the microscopic level. The smoother the paper, the finer and more uniform the surface, which can better absorb and disperse the heat of the print head. This enables ink dots to be more evenly distributed on the surface of the paper, thereby improving the clarity of printing. On the contrary, paper with a rough surface may result in uneven distribution of ink dots, reducing printing clarity.

2、 The influence of surface smoothness on printing speed

Under the same printing conditions, BOPP thermal sensitive synthetic paper with high smoothness usually supports faster printing speeds. This is because heat conduction is more efficient on a smooth paper surface, allowing the print head to heat up and release ink dots faster. However, paper with a rough surface may require more time and heat to ensure even distribution of ink dots, thereby reducing printing speed.

3、 The influence of surface smoothness on printing durability

Smoothness is also closely related to the durability of printed information. The surface of BOPP thermal sensitive synthetic paper with high smoothness is not easily worn, which can better protect the printed content from external environmental influences. This means that information printed on smooth paper can maintain longer readability and clarity. On the contrary, paper with a rough surface may be more susceptible to wear and contamination, leading to rapid fading or blurring of printed information.

4、 Considerations in practical applications

When choosing BOPP thermal synthetic paper, in addition to considering surface smoothness, a comprehensive evaluation should also be conducted based on specific application scenarios and requirements. For example, for occasions that require high-definition printing (such as medical diagnostic reports, supermarket price labels, etc.), BOPP thermal sensitive synthetic paper with high smoothness should be selected to ensure printing quality. For some application scenarios that do not require high printing quality (such as express waybills, temporary labels, etc.), the requirement for smoothness can be appropriately reduced to lower costs.

In summary, the surface smoothness of BOPP thermal sensitive synthetic paper has a significant impact on printing clarity, printing speed, and printing durability. When selecting and using BOPP thermal synthetic paper, these factors should be fully considered to ensure stable and reliable printing quality.
