How to solve the problem when printing round color copperplate label paper?

To solve the problems that occur when printing round color copper plate label paper, you can start from the following aspects:

First, paper selection and preparation

1. Paper quality:

Select high-quality round colored copper label paper to ensure that the surface of the paper is smooth and smooth, without wrinkles, damage and other defects.

Pay attention to the ink absorption performance of the paper, coated paper ink absorption ability is poor, may need to adjust the ink characteristics or use special inkjet ink.

2. Paper pretreatment:

Check the curvature of the paper before printing to ensure that the paper is smooth and avoid print quality problems caused by paper bending.

Keep the balance of temperature and humidity of the paper storage environment to avoid paper deformation.

Second, printing equipment and Settings

1. Equipment selection:

Select a printer suitable for printing round color copperplate label paper to ensure that the printer has high precision and high stability.

2. Print Settings:

Adjust the printer's print Settings according to paper type and size, including paper type, print quality, ink flow, and more.

Try using a different print mode, such as "CD/DVD mode", to improve the print result.

Third, ink and ink management

1. Ink selection:

Use inks that are compatible with round colored copper label paper to ensure that the ink adheres smoothly to the surface of the paper and dries at a moderate speed.

If necessary, consider using a dedicated inkjet ink or adjusting the viscosity of the ink to improve printing results.

2. Ink Management:

In the printing process, the viscosity and fluidity of the ink are regularly checked to ensure stable ink quality.

The use of heat and light resistant ink to adjust the base color ink to improve the durability of printed matter.

Fourth, operation skills and precautions

1. Pad technology and printing pressure adjustment:

Strictly control pad technology and printing pressure adjustment to ensure uniform and bright printing ink layer. The printing pressure of coated paper should be uniform and appropriate to avoid excessive pressure leading to powder drop or insufficient pressure leading to weak impression.

2. Anti-sticking measures:

Coated paper has weak ink absorption and smooth back, which is easy to produce sticky and dirty problems when multi-color overprinting. Anti-stick measures can be taken, such as adding an appropriate amount of anti-stick agent to the ink, but pay attention to control the amount so as not to affect the quality of the ink.

3. Cutting and post-processing:

Control the cutting pressure when cutting the finished product to avoid the phenomenon of "slipping paper" or embossing marks.

The printed round color copperplate label paper should be taken out in time and stored properly to avoid paper jam or deformation.

Fifth, problem diagnosis and solution

1. Loose ink, flow ink, pile ink phenomenon:

Check the ink characteristics, the ink absorption capacity of the paper, and the printer Settings, and try to reduce the ink flow rate, increase the ink setting rate, or use a heating device.

2. Color deviation and white spot problems:

Check whether the ink allocation is uniform, whether the printing pressure is uniform, and whether the plate is worn and aging, resulting in color deviation and white spot problems. According to the specific situation, adjust the ink ratio, replace the plate or adjust the printing pressure and other measures.

To sum up, to solve the problems in the printing of circular color copperplate label paper, it is necessary to consider paper selection and preparation, printing equipment and Settings, ink and ink management, operation skills and precautions, and problem diagnosis and solution. Through careful inspection and adjustment, we can ensure the printing of high-quality round color copper plate label paper.
