Colored silk screen overprinting of packaging containers (1)

With the development of the times, screen printing technology has undergone miraculous changes, and advanced automatic equipment has completely replaced the use of manual ink on the substrate. Regardless of speed, control or registration capabilities, today's presses have replaced traditional line printing and multicolor overprinting in most workshops. Moreover, automation has become demanded, even necessary, in companies that have used manual printing to gain profits. Today's image printing shop wants to maintain its competitive position, and has no choice but to adapt to customer requirements as quickly as possible and produce high-quality products. And gradually, to meet customer needs has been involved in the screen printing industry, container printing is no exception. Although many screen printers in the United States believe that it is possible to print screen images directly onto a container, it is quite different from printing on a flat object. Therefore, although the machines and systems that have been printed on containers have been significantly improved over the past 10 years, very few container printers have invested in this new device. This article provides a screen printing of direct printing onto containers, observing market changes and reminding container printers of the importance of opportunities. It considers why most container printers are reluctant to perform screen half-tone printing of containers, showing the basic steps required to perform this task. Why not use color screen printing? Why is it that the color screen printing is still delayed? Most people think that it is very difficult to color overprint objects on the same plane. It is obviously more difficult to print containers with uneven surfaces. In fact, there is no big difference in the color screen overprint between flat surface objects and uneven surface objects. The most obvious difference is the container itself. It usually must be pre-treated before ink can be attached, but usually the printed line or image part must be On the inflated surface of the container, to ensure that the squeegee passes over a flat surface. In the process of container printing decoration, the substrate is the only challenging part. In addition to checking the nuances of color overprinting, each container must also be lightly treated. These processes are mainly directed at the low or high points, flat areas, unstable parts of the space and Other inherent due to the container itself. The variable ingredients. Also note that fast printing is an important requirement, which makes the printing of containers with uneven surfaces more difficult. Some of these factors are not easily overcome, but beautiful prints can be produced with stable, high-quality printing equipment, as shown in Figure 1. ***** Figure 1: Container color registration ***** When North American container printers gradually adopt direct color screen printing, Europe has been successfully used for several years. As shown in the figure, beautiful images can be printed on various shapes of containers by controlling various aspects of printing.
