What is the production process of color copperplate label paper?

The production process of colored copper plate label paper is a complex and fine process, mainly including the following steps:

First, preliminary preparation

1.Design draft: First of all, you need to determine the design draft of the label, including the layout and collocation of colors, patterns, text and other elements. This step is usually done by designers, who design according to customer needs or market trends.

2.Color analysis: Analyze the color of the design drawing, determine the number and collocation of the required colors, and the way of printing (such as four-color printing, spot color printing, etc.).

3.Material preparation: Prepare the materials required for production, mainly colored coated paper. Coated paper is a paper coated with white paint, with good gloss and color expression, suitable for printing high-quality labels.

Second, print version production

1.Plate making: The production of printed plates according to design drawings. The platemaking process involves the use of computer software to convert design drawings into platemaking documents, and then the required plate material is produced on the platemaking machine. This step is one of the key links of printing quality.

2.Exposure: The produced plate is placed in the exposure machine for exposure processing, so that the pattern and text on the plate can be solidified. Exposure time and intensity need to be adjusted according to plate type and design requirements.

Third, printing

1.Ink mixing: Adjust ink colors according to the requirements of design drawings and printing plates. Performance parameters such as ink color, viscosity and drying speed need to be precisely controlled to ensure printing quality.

2.Printing operation: the prepared ink is evenly spread on the printing plate, and then the color coated paper is placed on the press for printing. During the printing process, parameters such as printing pressure, speed and ink volume need to be controlled to ensure that the ink can be accurately and evenly transferred to the paper.

Fourth, cutting and forming

1.Cutting: The whole printed label paper is cut according to the requirements to form labels of various sizes and shapes. The cutting process requires maintaining the sharpness of the tool and the accuracy of the cutting precision.

2.Molding: For labels that require special shapes (such as circles, ovals, etc.), molding processing is also required. The molding process usually uses molds for pressing or cutting to get the desired label shape.

Fifth, post-processing

1.Glazing: In order to improve the gloss and beauty of the label, the surface of the label is usually glazed. The glazing process is to coat the label surface with a layer of transparent paint (such as glazing oil), and then get a glossy label surface after drying and calender.

2.Inspection and packaging: Quality inspection of the finished product label to ensure that there are no defects, color differences and other problems. Labels that pass the inspection will be packaged for storage and transportation.

In summary, the production process of color copper plate label paper includes multiple links such as preliminary preparation, printing plate production, printing, cutting and molding, and post-processing. Each step requires careful operation and control of parameters to ensure the quality and performance of the final product.
