What are the advantages of using screen printing for packaging boxes in packaging printing

We expect the printed boxes to reach the expected results of our customers and our printers, and all the printing elements can be met, reducing the printing workload and shortening the delivery cycle of the products.

What are the advantages of using screen printing in the printing of packaging boxes?

First, the ink layer is thick.

This is unmatched by other printing methods. Under general conditions, the thickness of the ink layer of screen printing can reach more than 20μm, and some can reach 100μm. Therefore, the boxes printed by screen printing have the characteristics of rich and thick ink, strong three-dimensionality, and clear colours. Need a thin ink layer of packaging boxes we are also able to screen printing to complete, screen printing ink layer can also reach about 6μm, can be said that the adjustable and selective screen printing is very strong.

Second, the adaptability of the ink is strong.

We know that the other printing methods have high requirements for the ink, specifically to use uniform distribution, very fine particles and good flow of printing ink; although screen printing in order to improve the quality of the print, but also to use good quality ink, but because it is the choice of leakage printing method, relatively speaking, the requirements of the ink is not particularly severe, liquid ink, powder oil black, water-based ink, oil-based ink are able to use of.

Third, the printable surface of the substrate is wide.

Screen printing has “all-purpose printing”, can say that in addition to water and air, screen printing can print all things, sounds a bit exaggerated, but this is the fact of existence. Screen printing can be printed on substrates such as rigid plastics, flexible packaging plastics, plastic woven bags, wood, metal, glass, ceramics, and so on, and not constrained to a variety of shapes, sizes.

Fourth, printing pressure is small.

Because the screen printing version of the choice of soft and flexible materials, its printing pressure is small, and can be printed on easily damaged items. In addition to a large number of advantages, there are some of its own lack, such as printing accuracy is not, generally can not meet the requirements of fine printing; in addition, suitable for packaging printing mechanization and automation of a higher degree of equipment is also less, so the share in the field of packaging printing is still relatively small. However, in accordance with the current level of development, I believe that in the near future this status quo will change.

We in the choice of packaging printing methods, not only to consider the advantages and disadvantages of different printing methods, such as printing costs, print quality and other aspects of consideration, but also based on the characteristics of the substrate, for example, flexographic printing equipment input is relatively small, while gravure printing equipment is generally more expensive. However, the quality of flexographic printing is now less than gravure printing, but with the improvement of anilox production skills and flexographic plate making skills, flexographic printing quality will gradually improve.

In terms of consumables, flexographic printing requires a large number of consumables dependent on imports, while gravure printing consumables have been completed domestically, and domestic consumables can be completely self-sufficient. In terms of environmental protection, flexographic printing has a very high environmental protection, while gravure printing is relatively poor, to be improved. From the perspective of printing costs, flexographic printing is more economical when printing small quantities of products, while gravure printing is more suitable for high-volume printing. However, no matter which printing method is chosen, the characteristics of the box are taken into account.

We generally expect the printing equipment we use to meet the following requirements:

1, printing equipment can adapt to a variety of different properties of the substrate material;

2, printing equipment printing out of the packaging box can reach the ideal quality requirements;

3, because the packaging products are basically mass production, to ensure the consistency of the printed colour, and to reduce the equipment in the production process downtime;;

4, the overall energy consumption of the printing equipment should be low;

5, from the perspective of environmental protection, the equipment should be selected to close the structure, and has a waste solvent recovery equipment.
