How to avoid color inconsistency in BOPP thermal synthetic paper during the printing process?

To avoid color inconsistency during the printing process of BOPP thermal sensitive synthetic paper, the following aspects can be taken into consideration:

1、 Choose high-quality materials

Paper selection:

Select BOPP color thermal sensitive synthetic paper with more advanced coating formula and finer production process to ensure uniform and stable thermal sensitive coating on the paper, reducing the possibility of color inconsistency.

Ink selection:

Choose ink that meets the printing color requirements and follow the procurement process to avoid using ink from different manufacturers for color matching. It is best to use ink from the same manufacturer to ensure the stability and consistency of the ink.

2、 Control printing parameters

Printer settings:

Check and correctly set the various parameters of the printer, such as printing temperature, pressure, speed, etc., to ensure that these parameters are suitable for the BOPP color thermal synthetic paper used.

Print head maintenance:

Regularly inspect and maintain the print head to ensure its cleanliness and proper functioning, avoiding unclear or inconsistent colors caused by dirty or damaged print heads.

3、 Optimize storage conditions

Storage environment:

Store BOPP thermosensitive synthetic paper in a dry, ventilated, and dust-free environment, avoiding direct sunlight and high temperature and humidity conditions. Improper storage environment may lead to a decrease in material performance and affect printing results.

Storage time:

Control the storage time of paper to avoid material aging caused by prolonged storage. Although the specific shelf life may vary depending on material quality and storage conditions, prolonged storage may affect the color and physical properties of printed products.

4、 Establish a color management system

Color standard:

Determine the upper and lower limits of product color standards with customers, develop "standard samples", and conduct quality control based on the color of the standard samples during the production process.

Color detection:

Use color measuring instruments to measure and calibrate the color of printed materials to ensure color accuracy. Regularly conduct color checks to promptly identify and resolve color differences.

Initial and final sample signing and inspection:

Improve the sample signing and inspection system for the first and last pieces to ensure color consistency during the production process. Workshop managers and operators should strengthen inspections and spot checks to promptly detect and handle products that exceed the reasonable range of color difference.

5、 Pay attention to operating standards

Avoid scratching and contamination:

During use, be careful to avoid scratching and contaminating the paper to avoid affecting the appearance quality and information readability of the printed product.

Device compatibility:

Confirm the compatibility of the printer and printing equipment used with BOPP thermal synthetic paper to avoid color inconsistencies caused by device incompatibility.

In summary, by selecting high-quality materials, controlling printing parameters, optimizing storage conditions, establishing color management systems, and paying attention to operating standards, the problem of color inconsistency in BOPP thermal synthetic paper during the printing process can be effectively avoided.
