What should be noted when printing BOPP thermal synthetic paper?

When printing BOPP thermal synthetic paper, the following key points should be noted to ensure printing quality and effect:

1、 Paper processing and preparation

Paper inspection:

Before printing, the BOPP thermal sensitive synthetic paper should be carefully inspected to ensure that the surface of the paper is flat, scratch free, and stain free.

Check the batch and shelf life of the paper to avoid using expired paper.

Environmental adaptation:

Place the paper in advance in the printing workshop to adapt to the temperature and humidity environment, avoiding paper deformation or printing problems caused by environmental changes.

2、 Printing parameter settings

Printing temperature:

Reasonably set the printing temperature based on the thermal characteristics of BOPP thermal sensitive synthetic paper. Low temperature may result in unclear printing, while high temperature may damage the paper or print head.

Printing speed:

Adjust the printing speed appropriately while ensuring the printing quality. A printing speed that is too fast may result in poor printing quality, while a speed that is too slow may reduce production efficiency.

Printing density:

Adjust the printing density according to actual needs to ensure that the printed image or text is clear and full.

3、 Printing equipment adjustment

Device compatibility:

Before printing, confirm the compatibility between the printing equipment and BOPP thermal synthetic paper to avoid printing problems caused by equipment mismatch.

Print head cleaning:

Regularly clean the print head to avoid printing quality issues caused by clogging or contamination of the print head.

Tension control:

During the printing process, it is important to control the tension of the paper reasonably to avoid deformation or tearing caused by excessive tension.

4、 Printing process monitoring

Color monitoring:

Real time monitoring of printed color effects to ensure color consistency with expectations. If there is a color deviation, the printing parameters should be adjusted in a timely manner.

Alignment monitoring:

Pay attention to printing alignment marks to ensure that the printed content is accurately positioned on the paper.

quality testing:

During the printing process, regular quality checks are conducted on the printed samples to ensure stable printing quality.

5、 Subsequent processing and storage

Drying treatment:

After printing is completed, dry the paper to ensure that the printing ink is completely dry and avoid blurring or sticking problems caused by ink not drying.

Dust and pollution prevention:

Store the printed BOPP thermosensitive synthetic paper in a dry, ventilated, and dust-free environment to prevent dust and pollutants from adhering to the paper.

Avoid long-term storage:

Reasonably purchase and store paper according to actual needs to avoid paper aging or quality problems caused by long-term backlog.

In summary, when printing BOPP thermal synthetic paper, attention should be paid to paper handling and preparation, printing parameter settings, printing equipment adjustments, printing process monitoring, and subsequent processing and storage. Only by comprehensively considering and properly addressing these issues can we ensure printing quality and effectiveness.
