Advantages And Disadvantages Of Screen Printing
Screen printing is a printing technology with very distinctive printing characteristics and imaging processes. Because of the flexibility and lack of adaptability of screen printing, more design works even use screen printing instead of offset printing in printed materials that use paper as a printing carrier to express creative design ideas more vividly. The choice is indeed a good idea.
Screen printing equipment is simple, easy to operate, easy to print and plate, and low in cost. Screen printing requires the following elements: printing station, screen printing screen, ink, scraper and printing carrier.
The screen printing screen is different from the offset printing. The screen printing screen has a net structure. The screen holes on the printing plate are ink holes instead of the screen holes on the non-text portion. Extrusion allows the ink to be transferred to the substrate through the mesh of the graphic part to form the same graphic as the original. After the drying process, the screen printing process can be completed.
Of the four common types of printing, offset printing, embossing, or gravure are all printing methods that use flat materials as the main carrier, but screen printing is even better. So what are the advantages of screen printing?
First of all, screen printing can use paper as a carrier, and also can use other materials such as plastic products, metal or leather products as printing materials to print, which has a wider adaptability.
Secondly, offset printing, embossing, or four-printing are all flat printing, and screen printing can be printed on spherical, curved or even uneven surfaces. The application of Fan Guozhi is beyond the reach of other printing methods. Screen printing has become a designer Use of very common process techniques in print design.
The advantages of screen printing are irreplaceable in terms of using dark-colored paper as a print carrier. This is due to the thick ink layer of screen printing, which is 5-6 times thicker than offset printing, and the coverage is much stronger than other printing methods. The surface texture is also richer and brighter than the offset printing ink. In offset printing, four-color images are printed on dark paper, which must be printed with white ink first, and then printed in four colors. The efficiency and effect are not as good as screen printing.
In addition, the wide range of inks that can be used for screen printing is not limited by oiliness or water, which makes screen printing have a wider application space. The maximum printing format of screen printing can reach 300cm or even 400cm. If the technology for making screen printing screens can be further improved, it will not be difficult to produce larger-sized printed matter.
Screen printing has such a wide range of printing scenes, can it replace other printing processes? Definitely not. Screen printing also has its drawbacks.

First of all, in terms of the quality of printed materials, the quality of screen printing cannot be better than offset printing. Due to the screen printing screen and the squeegee operation (especially when manual operation), you cannot expect the printed products to have excellent quality assurance. You also need to be mentally prepared, because manual screen printing can cause a lot of waste and defective products.

Secondly. It is relatively difficult to produce screen printing products in large quantities. Printing products that can be completed in a few minutes in offset printing may require double the man-hours in screen printing.

Third, the four-color overprint gradient image cannot be realized freely in screen printing like offset printing.

In short, it may be more appropriate to understand screen printing as being easier to complement ordinary offset printing. When special printing carriers or different artistic effects are required, screen printing is another option that designers can try to apply.
