What are the problems that may occur during the printing process of BOPP color thermal sensitive synthetic paper?

BOPP color thermal sensitive synthetic paper may encounter the following issues during the printing process:

1、 Color rendering issue

Uneven color rendering:

Reason: Uneven application of thermal sensitive coating, improper temperature control of print head, uneven heating of paper, etc.

Solution: Ensure even application of the thermal sensitive coating, adjust the print head temperature to a suitable range, and maintain smooth paper transport during the printing process.

Unclear color rendering:

Reason: Poor quality of thermal sensitive coating, low printing resolution, aging print head, etc.

Solution: Choose high-quality thermal sensitive coating materials to improve printing resolution, and regularly replace aging print heads.

Color deviation:

Reason: Unstable thermal coating formula, printing temperature fluctuations, paper batch differences, etc.

Solution: Optimize the thermal sensitive coating formula, stabilize the printing temperature, and ensure consistency between paper batches.

2、 Printing quality issue

Printing blur:

Reasons: print head wear, fast printing speed, uneven paper surface, etc.

Solution: Regularly clean and replace the print head, adjust the printing speed to a suitable range, and ensure that the paper surface is flat.

Print broken line:

Reasons: clogged print head, poor ink ribbon quality, poor contact between paper and print head, etc.

Solution: Clean the clogging of the print head, replace the high-quality ink ribbon, and ensure that the paper is in close contact with the print head.

Paper jam:

Reason: Paper size does not match the printer, printer feed mechanism malfunction, etc.

Solution: Choose a paper size compatible with the printer, check and repair the printer's feed mechanism.

3、 Paper damage issue

Paper deformation:

Reason: High temperature and moisture on the paper during the printing process.

Solution: Control the printing temperature to ensure that the paper is stored and used in a dry environment.

Paper damage:

Reason: Poor paper quality, printer feed mechanism too tight, etc.

Solution: Choose high-quality paper and adjust the tension of the printer's feed mechanism.

4、 Other issues

Short lifespan of print head:

Reason: Use of inferior paper, frequent cleaning of print heads, etc.

Solution: Choose high-quality paper to reduce unnecessary cleaning of the print head.

Slow printing speed:

Reason: Insufficient printer performance, improper print settings, etc.

Solution: Upgrade printer hardware and optimize print settings to improve printing speed.

In summary, the possible problems that may occur during the printing process of BOPP color thermal synthetic paper involve multiple aspects such as color development, printing quality, and paper damage. To ensure printing quality, it is recommended to choose appropriate paper and printer, optimize printing settings, and regularly maintain and upkeep the printer.
