Combined printing method ADAPTS to the development of modern printing industry needs and format design, to the printing manufacturers have brought rich profits, rapid development. In foreign countries, more than 10% of the label products use combination printing. For example, transparent material labels. Clear material labels usually require screen printing of the background color, followed by color or convex printing of the logo and pattern. The printing effect of this method is different from that of ordinary label printing. It can improve the quality of products very well.
The current label market has higher and higher requirements for printing technology. The requirements of label product printing mainly include: they need to be eye-catching, have a strong visual impact, be subtle in local details, and have a three-dimensional sense of surface decoration; Can produce higher added value, with good anti-counterfeiting effect. Obviously, a single printing method can not meet these requirements of label product printing.
1. Strong printing adaptability. The three methods of gravure printing generally can only be printed on a flat surface. Screen printing can be printed not only on a flat surface, but also on a curved surface. Printing on spherical and concave surfaces;
2. Thick ink layer, strong three-dimensional sense, rich texture. The ink layer thickness of offset printing and convex printing is generally 5 microns, the ink layer thickness of concave printing is about 12 microns, and the ink layer thickness of flexible printing is 10 microns. The ink layer thickness of screen printing is much higher than the above ink layer thickness, which can generally reach about 30 microns. Screen printing ink layer is thick, printing quality is rich, three-dimensional sense is strong, other printing methods can not be compared. At the same time, screen printing can not only be monochrome printing, but also can be color printing;
3. Soft layout. Screen printing layout is soft, with a certain degree of elasticity. It is not only suitable for printing soft things such as paper and fabric, but also for printing hard things such as glass. Ceramics, etc.;
4. Various types of ink can be used for screen printing. Namely: oily. Water-based. Synthetic resin emulsion type. Various types of ink, such as powder;
5. Screen printing has small imprint power. Due to the low pressure used in the printing process, it is also suitable for printing on fragile objects.
