Combined printing, the hottest topic in recent years, represents the latest trend in high-end label and packaging printing today. Combined printing, as the name implies, is a processing method that combines various printing methods together with different post-processing techniques to produce finished or semi-finished products. It combines the advantages of various printing and post-processing, and also combines the disadvantages of various printing and post-processing! How to make full use of their advantages and avoid shortcomings is the direction of joint efforts of various suppliers and printing companies for many years. Thank you very much for the development of contemporary science and technology, especially the development of servo control technology, to turn the goal of years of joint efforts into reality! The equipment supplier has solved the problem from the equipment and turned the idea into reality; the printer has fully exerted the performance of the equipment, and the beautiful products, beautiful packaging and colorful world are displayed in front of everyone.
Combination printing, everyone has a different understanding, what are the main combination methods? At present, the main combination methods are: the combination of flexo and screen printing; the combination of flexo and gravure printing; the combination of flexo printing and offset printing; the combination of flexo printing and relief printing; the combination of flexo printing and silk printing; the combination of flexo printing and silk printing Combination of screen printing and gravure printing; combination of flexo printing and silk printing, embossing printing; combination of flexo printing and offset printing, silk printing; combination of offset printing, silk printing, flexographic printing and gravure printing; offset printing, flexographic printing, silk printing, gravure printing and post-processing Combination of processes; plus printing of variable information in conjunction with digital printing or inkjet. Different printing combinations have created brilliance at different stages, such as the McAndy 4150 in the 1990s, the Jetlas EM model at the beginning of this century, the MO of Newport, etc., but with the development of technology, the competition Intensified, the improvement of life requirements, people have put forward higher requirements for combination printing, so what can really represent the highest level of label and packaging combination? It must combine today's most important and advanced printing methods and post-processing procedures, namely: offset printing, flexo printing, silk screen printing, gravure printing, digital printing and post-processing procedures such as cold transfer, hot stamping, laminating, indentation, unevenness , A combination of slitting, die cutting and inline quality inspection. How to combine flexo printing with light pressure printing, gravure printing with heavy pressure, hot stamping, offset printing with long ink path, etc., is a problem in itself. It is a model that can truly combine these high-end technologies and produce economic benefits. That is a limited number of companies: Nuova Gidue srl of Italy New Kiddu; Gallus of Switzerland; Nilpeter of Newport of Denmark; the model is the Spande Xpannd of New Kiddu and RCS of Gelasi , MO of Newport Corporation.
Let us know the advantages and disadvantages of the main printing methods:
In the printing combination, 'no offset printing is not a real combination'! Offset printing, China's most extensive and popular printing method, includes everything from advertising designers to all practitioners and end users. Everyone has a 'offset printing' vision to see everything. The printing cost of offset printing is low, the resources are quite abundant, and the technical personnel are sufficient. The printing overprint is quite accurate within +/- 0.02, the dot reproduction is the best, the excessive or excessive transition is very beautiful, and the dot restoration in the most deformable dot area will not exceed 10-15%. Usually printed products range from 175 to 300 LPI. Its printing method is transferred to the blanket through the PS plate and then transferred to the substrate. However, the offset printing has some shortcomings in the field, and it is difficult to keep the ink color consistent. Sometimes, the large field needs to be printed twice.
Flexo printing is a developing environmentally friendly printing, also known as green printing, which is a very common printing method in Europe and America. The range of printing materials is very wide, excellent field, line printing and glazing. Large-area field printing is reflected in saturation and consistency, the colors are bright and beautiful, and the printed matter can keep the ink color consistent! Usually print 133-175LPI products, water ink, alcohol ink and UV ink are commonly used ink. The printing is a short ink path, the ink transfer roller transfers the ink to the resin plate through the mesh mosquito roller and then directly prints on the substrate, and the printing is light pressure. However, flexographic dot printing has large deformation, and consumables such as ink and printing plates are relatively expensive compared to other printing methods.
Gravure printing is a wide and universal printing method other than offset printing. The excellent solid (30um thick ink layer) and metal ink printing are most commendable; usually printing 100-359LPI products, high printing quality; high production efficiency, hue consistency Good, good material adaptability, high printing durability; gravure printing with other printing can print metallic luster, similar to hot stamping, cost-effective. Gravure printing is the most direct heavy pressure printing. The metal plate roller is directly inked and printed on the substrate. Gravure printing mainly uses solvent ink, which is not environmentally friendly, and gravure printing water-based ink is still in development; fine dot printing is lacking, and dots are easy to lose.
Screen printing is a supplementary printing, which is mainly reflected in higher ink hiding power and color strength. The thickness of the ink layer is 20-100um. It is more suitable for special surface treatment, uneven surface finishing, transparent film primer, Braille printing and so on. Due to the thick ink layer, the printing speed is slow, and the rotary screen is relatively expensive.
Relief printing is used in many ways in Chinese label printing. It has low cost, low edition fee, limited printing quality and printing speed. Due to the great correlation between ink color transfer and speed, contact time and temperature, it leads to lack of on-site printing. The consistency is poor, and it is a printing method eliminated in Europe and America.
