How to optimize the printing effect of BOPP color thermal synthetic paper?

To optimize the printing effect of BOPP color thermal synthetic paper, you can consider and operate from the following aspects:

First, choose the appropriate printing equipment and ink

1. Printing Equipment:

Select high-precision, high-resolution printing equipment to ensure that the print head can precisely control the size and position of the ink dot, thereby improving the clarity and detail of the printed image.

Consider using printing equipment with corona processor or flame impact processing capabilities that can surface treatment BOPP color thermal synthetic paper before printing, improving ink adhesion and printing results.

2. Ink selection:

Select special inks suitable for BOPP color thermal synthetic paper, these inks should have good fluidity and adhesion, and can be uniformly attached to the surface of the paper to form a clear, full printing effect.

Pay attention to the drying speed and curing performance of the ink to ensure that the ink can be dried and cured quickly after printing to avoid the occurrence of adhesion and blurring.

Second, optimize the printing process parameters

1. Printing pressure:

Reasonably adjust the printing pressure of the printing press to ensure that the ink can be evenly transferred to the surface of the paper, while avoiding excessive pressure resulting in paper deformation or ink penetration.

2. Printing speed:

Control the printing speed so that the ink has enough time to spread and dry on the surface of the paper to avoid uneven or fuzzy printing caused by too fast speed.

3. Drying temperature:

Adjust the drying temperature according to the drying characteristics of the ink to ensure that the ink can dry quickly at the appropriate temperature to avoid the occurrence of adhesion and blurring.

Third, surface treatment

1. Corona treatment:

Corona treatment is carried out on BOPP color thermosensitive synthetic paper before printing to increase the polarity of the paper surface through oxidation, improve the adhesion of the ink and printing effect.

2. Plasma treatment:

High energy surface treatment methods such as plasma treatment can also be used to improve the surface energy and printing adhesion of the paper.

Fourth, control environmental factors

1. Humidity and temperature:

Keep the humidity and temperature of the printing shop stable, avoid excessive humidity resulting in paper hygroscopic deformation or uneven ink diffusion, and excessive temperature resulting in ink drying too fast or paper deformation.

2. Cleanliness:

Ensure the cleanliness of the printing equipment and the environment, avoid dust, impurities and other pollution of the paper surface, affecting the printing effect.

Fifth, quality control and testing

1. Regular testing:

Regular quality testing of printing equipment and ink to ensure stable equipment performance and ink quality.

2. Sample testing:

Sample testing before printing to ensure that the printing results meet customer requirements and quality standards.

Through the comprehensive application of the above measures, the printing effect of BOPP color thermal synthetic paper can be effectively optimized, the clarity and adhesion of printed matter can be improved, and the needs of customers for high-quality printed matter can be met.
