What are the die-cutting processes of color copperplate label paper?

The die-cutting process of color copperplate label paper mainly includes the following steps:

First,Preliminary preparation

1.Design: First of all, according to the actual needs of the label design, including the selection of appropriate colors, fonts, patterns and other elements, and determine the size and shape of the label.

2.Plate shooting: According to the requirements of the label design draft, the corresponding printed version is produced (although the question is mentioned in the copper plate, but in the modern printing process, the photosensitive resin version or CTP version is more commonly used), and the image and text information is transmitted to the printed version.

Second,Printing

The printing plate is placed on the printing press, the printing ink is smudged on the printing plate through the printing roller, and then the pattern on the printing plate is printed on the colored coated paper through the pressure of the printing press.

Third,Die cutting process

1.Drawing die drawing: Die drawing is the full plate label expansion drawing after the printing process, which is a key link in the production of die cutting plate. If you use a full-page assembly system, you can directly output the die drawing in the printing process to ensure that the printing plate and the die cutting plate have a uniform standard.

2.Cutting knife template: According to the knife mold diagram, use a laser cutting machine or other high-precision cutting equipment to cut the knife template. Laser cutting is controlled by computer with high precision.

3.Install die cutter and indentation line: Install die cutter and indentation line on the knife template. Die cutter according to the different shape of the cutting edge commonly used standard knife and double peak knife, indentation line is used to complete the indentation work at the folding of the label, its thickness and height should be selected according to the thickness of the label paper.

4.Open connection points: Use special equipment (such as knife line punch machine) to open connection points on the die cutting plate to ensure that the label can be smoothly discharged during die cutting, while avoiding damage to the knife line and lap Angle.

5.Adhesive strip: In order to prevent the die cutter and indentation line from sticking to the paper during die cutting, it is necessary to paste elastic die cutting rubber strips on both sides of the knife line. The choice of die cutting rubber strip should be determined according to the speed of the die cutting machine and the conditions of the die cutting live parts.

6.Test cutting plate: After the die cutting plate processing is completed, it is necessary to test cut on the die cutting machine. If the test cutting result is not ideal (such as local cut opaque), it is necessary to carry out the plate treatment, that is, the die cutter is highly compensated.

7.Make indentation bottom template (if necessary) : For some labels that need to be folded, you also need to make indentation bottom template to ensure that the folding line is accurate and beautiful.

8.Trial die cutting and signing production: After the above steps, carry out formal die cutting and signing production to ensure that the die cutting labels meet the design requirements.

Fourth, post-processing

According to the needs, the labels after die cutting are pressed, hot stamping, laminating and other post-processing processes to improve the overall texture and use effect of the labels.

It should be noted that the specific steps of the die-cutting process may vary depending on equipment, materials, design requirements and other factors. Therefore, in actual operation, it is necessary to adjust and optimize according to the specific situation. At the same time, with the continuous progress of technology, the die-cutting process is also constantly developing and improving.
