How to ensure the clarity of printing on hanging tag copperplate paper?

Ensuring printing clarity is crucial in the printing process of hang tag copperplate paper. Here are some key measures to ensure clear and high-quality images and text are printed:

1、 Optimize printing equipment settings

Adjust printing pressure:

Ensure that the pressure setting of the printing machine is appropriate, which can ensure good adhesion between ink and paper, and avoid dot enlargement or wear caused by excessive pressure.

Adjust the pressure of the printing cylinder appropriately according to the thickness of the paper and the characteristics of the ink.

Control printing speed:

Excessive printing speed may result in insufficient contact time between ink and paper, affecting printing clarity.

Set a reasonable printing speed to ensure that the ink has enough time to dry and solidify on the paper.

Regular maintenance of printing equipment:

Regularly inspect the drum, ink hopper, scraper and other components of the printing machine to ensure that they are in good condition.

Clean up ink residue and impurities inside the printing machine to avoid negative impact on printing quality.

2、 Choose high-quality ink and paper

Choose ink suitable for copperplate paper:

Choose ink that is compatible with copperplate paper to ensure the fluidity, dryness, and adhesion of the ink during the printing process.

Select ink with appropriate viscosity and color according to printing requirements.

Choose high-quality copperplate paper:

Ensure that the surface of the paper is flat and smooth, which is conducive to the uniform adhesion of ink and the improvement of printing clarity.

Choose copperplate paper with good ink absorption and dimensional stability.

3、 Adjust printing process parameters

Adjust the uniformity of ink coating:

Ensure even application of ink on the paper to avoid ink accumulation or shortage.

Use professional ink coating equipment or techniques, such as scraper coating, roller coating, etc.

Control the wear and tear of the printing plate:

Regularly check the wear and tear of the printing plate and replace the aging printing plate in a timely manner.

Use high-quality printing materials to extend the service life of printing plates.

Adjust the color and viscosity of the ink:

Adjust the ink color and viscosity according to printing requirements to ensure the accuracy and clarity of printing colors.

Use professional color grading equipment and tools, such as colorimeters, viscometers, etc.

4、 Pay attention to printing environment control

Control temperature and humidity:

Maintain stable temperature and humidity in the printing workshop to avoid performance changes of paper and ink due to environmental changes.

Use professional temperature and humidity control equipment, such as air conditioners, dehumidifiers, etc.

Avoid contamination by dust and impurities:

Ensure that the printing workshop is clean and dust-free, avoiding negative effects of dust and impurities on printing quality.

Use professional cleaning equipment and tools, such as vacuum cleaners, dust-free cloths, etc.

In summary, ensuring the clarity of hanging plate copperplate paper printing requires starting from multiple aspects such as printing equipment settings, ink and paper selection, printing process parameter adjustment, and printing environment control. By taking these measures, it can be ensured that high-quality and clear hang tag products are printed.
