What are the post-processing processes of round color copper plate label paper after printing?

There are a variety of post-processing processes for circular color copperplate label paper after printing, which aim to improve the quality, appearance and functionality of the label paper. Here are some common post-treatment processes:

1. Film coating process

Coating type: Coating process can be divided into two kinds of coating subfilm and coating bright film. Although the subfilm is not as bright as the bright film, it is more elegant.

Performance improvement: The film can enhance the performance of moisture, sun protection, wear resistance, anti-fouling, water resistance, heat resistance and so on.

2. UV printing

Process characteristics: UV printing is a printing process by ultraviolet light drying, curing ink.

Effects and advantages: UV printing can increase the brightness and artistic effect of the product, protect the surface of the product, with high hardness, corrosion friction resistance, not easy to scratch and other characteristics. Some of the coating products are changed to UV, which can also meet the environmental protection requirements.

Note: UV products are not easy to bond, and sometimes need to be solved by local UV or polishing.

3. Gold/silver stamping

Process description: Metal foil (gold, silver foil) is hot printed on the surface of the printed matter using the method of thermal pad printing, so that the surface of the printed matter has a metallic texture and effect.

Application: This process is often used to enhance the high-end sense and visual effect of label paper.

4. Embossing/stamping

Process characteristics: The use of pressure to press graphics or text on the surface of the print to achieve a special touch and visual effect.

Effect: The surface of the label paper after embossed will have a concave and convex feeling, increasing the sense of touch.

5. Flocking

Process description: Brush a layer of glue on the surface of the printed matter, and then paste some fluff material to make the surface of the printed matter have the effect of flannelette.

Application: This process is suitable for label paper that needs a soft touch.

6. Embossing

Process characteristics: The use of concave and convex die, under a certain pressure to produce plastic deformation of the printed matter, so that the surface of the printed matter art processing.

Effect: After embossing, the surface of the printed matter presents different patterns and textures in different shades, which has an obvious three-dimensional sense of relief and enhances the artistic appeal of the printed matter.

7. Glazing

Form: There are three forms of glazing, which are coating, calender and UV glazing.

Performance improvement: It can enhance the moisture, sun protection, wear resistance, anti-fouling and water resistance of the printed matter.

8. Die cutting

Process description: According to the design requirements of the printed matter, a special die cutter is made, and then the printed matter or other substrate is rolled and cut into the desired shape or mark under the action of pressure.

Application: The die cutting process is particularly common in the production of label paper and is used to cut the label paper into a circle or other desired shape.

9. Folding and indentation

Although mainly used for book binding: in the production of some special shapes of label paper, folding and indentation processes may also be involved to form a specific three-dimensional structure.

10. Punch holes

Application: Punch holes in printed matter according to size as required, commonly seen in label paper that needs to be hung or used for specific purposes.

11. Drop plastic

Process characteristics: The thermoplastic polymer material is molded into the design shape according to the requirements, and the printing surface is cured at room temperature to obtain the crystal convex effect.

Application: This process is often used to enhance the high-end and decorative sense of label paper.

The application of these post-treatment processes can be selected according to the specific needs and design of the label paper to achieve the best results and performance.
