What is the production process of self-adhesive copper plate label paper?

The production process of self-adhesive copper plate label paper is a complex process involving multiple steps. The following is a detailed analysis of the process:

First, design and typesetting

1.Requirements collection and design: According to customer requirements, design the label pattern, text, color and other content. This step is usually done by the customer or a professional designer, ensuring that the label design matches the customer's brand image and usage needs.

2.Software typesetting: Use professional design software, such as Adobe Illustrator, CorelDRAW, etc., to typesetting labels. During the design process, it is necessary to ensure that the resolution of the design file is high enough (usually not less than 300dpi) to guarantee the subsequent printing quality.

Second, preparation for printing

1.Material selection: The selection of coated paper as the base material of the label, because the coated paper surface is smooth, high whiteness, uniform ink absorption, suitable for printing high-quality labels. At the same time, prepare self-adhesive materials to ensure that the stickiness of the self-adhesive is suitable for the paste needs of customers.

2.Printing plate production: According to the design document to produce printing plate, such as CTP or resin plate. The production accuracy of the printing plate directly affects the printing effect, so it is necessary to ensure that the production of the printing plate is accurate.

Third, printing

1.Printing on the machine: the prepared coated paper and self-adhesive materials are sent to the printing machine and printed according to the design document. In the printing process, it is necessary to choose the appropriate printing method (such as offset printing, flexo printing, gravure printing, etc.), and adjust it according to the quantity, quality requirements and cost of the label.

2.Quality control: In the printing process, the accuracy and consistency of the color need to be strictly controlled to avoid color differences. At the same time, it is also necessary to pay attention to the overprinting accuracy and printing quality to ensure that the printing effect of each label meets the standard.

Fourth, post-processing

1.Die cutting: Use a die cutting machine to die cut the printed label so that it becomes a single label shape. The die cutting process needs to be adjusted precisely according to the shape and size of the label to ensure the quality of the die cutting.

2.Waste removal: Remove the label waste after die cutting, leaving only the required label. Be careful not to damage the edges and surfaces of the labels during the waste removal process.

3.Slitting: The label after waste is slitted to make it the appropriate size. The selection and adjustment of the slitting machine also needs to be precisely adjusted according to the size and requirements of the label.

4.Surface treatment: According to the need, the label surface treatment, such as coating, glazing, etc., to increase the durability and beauty of the label.

Fifth, inspection and packaging

1.Quality inspection: The quality inspection of the label after cutting is carried out to check whether the quality, size and color of the label meet the requirements. If there are unqualified labels, they need to be removed or reworked.

2.Packaging: The qualified labels are packaged, usually in roll or flat packaging. During the packaging process, pay attention to the protection of the label to avoid damage.

Sixth, delivery and after-sales

1.Delivery: The packaged labels will be shipped according to customer requirements. Check the order information before shipping to ensure that it is correct.

2.After-sales service: Provide perfect after-sales service, including label use guidance, quality problem handling, etc., to ensure customer satisfaction.

In summary, the production process of self-adhesive copper plate label paper is a complex process involving multiple steps such as design, printing, post-processing, inspection and packaging. Each step requires strict quality control to ensure that the quality of the final product meets customer needs.
