What do I need to do before printing color label paper?

Before printing color label paper, you need to do the following preparations:

First, material preparation

1. Coated paper:

Select the coated paper suitable for printing, considering its thickness, smoothness, ink absorption and other factors to ensure the printing quality.

2. Printing ink:

According to the design requirements of the label, choose a printing ink with rich colors and moderate consistency.

3. Coated adhesive (if required) :

To enhance the waterproof, antifouling, and durability of the label, prepare an appropriate amount of laminating glue.

4. Other auxiliary materials:

Such as transparent film (used to make transparent mold), moistening liquid and so on.

Second, equipment inspection and adjustment

1. Copper plate making equipment:

Ensure that the copper plate making equipment is in good working condition and can accurately transfer design patterns and text to the copper plate.

2. Printing machine:

Check the press pressure, speed, ink flow and other Settings to ensure that they meet the requirements of printing coated paper.

According to the paper characteristics and printing needs, adjust the relevant parameters of the press.

Third, layout production

1. Design pattern and text:

Use design software or graphic editing software to design the label's pattern and text, ensuring that they are clear and accurate.

2. Make transparent mold:

The designed pattern and text are transferred to the transparent film by printing or hand-painting to form a transparent standard mold.

3. Copper plate making:

Apply the moistening solution on the surface of the copper plate and place the transparent mold on the copper plate.

After exposure, plate opening, development, plate washing and other steps, the production of publishing surface.

Fourth, test and analysis

1. Paper test:

Test and analyze each batch of coated paper, including smoothness, pH, absorption, dryness, flexibility and surface bonding strength.

According to the characteristics of the paper, adjust the printing process parameters, such as the viscosity, fluidity, dryness and anti-sticking measures of the ink.

2. Printing test:

Before the formal printing, the printing test is carried out to check whether the printing effect meets the requirements.

According to the test results, adjust the press pressure, speed, ink flow and other Settings to ensure stable printing quality.

Fifth, environmental preparation

1. Temperature and humidity control:

In the printing process, the temperature and humidity need to be strictly controlled to ensure the stability of the printing quality.

Adjust the temperature and humidity in the workshop according to the printing equipment and paper requirements.

2. Clean the work area:

Keep the working area clean to avoid dust and paper scraps and other debris affecting the printing quality.

Sixth, personnel training

1. Operation training:

Train operators to ensure that they are familiar with the operating methods and printing processes of the printing equipment.

Emphasis on operational norms and safety precautions to improve printing efficiency and quality.

2. Quality awareness training:

Cultivate the quality awareness of operators, so that they understand the importance of printing quality to the effect of label use.

Operators are encouraged to actively find problems in the printing process and solve them in time.

Through the above preparation, you can ensure that the printing quality of color copper plate label paper is stable and reliable to meet the needs of use.
