What are the disadvantages of traditional screen printing?

1, the screen printing cost of the film is high, and the printing cost is expensive;

2, the color is complex, and once the version is finalized, it cannot be modified;

3, the process is complicated and the production cycle is long;

4. The cost of screen printing is high, and screen printing spots cannot be eliminated, so mass production is needed to reduce the cost;

5. Thermal sublimation ink is used for thermal transfer printing. First, print the picture on the transfer paper, and then transfer it to the surface of the medium. There are several problems: color deviation and positioning deviation. The finished drawing is also easy to scrape off and has poor firmness. Generally, protective film should be sprayed. In addition, the transfer of special media also requires flexographic printing.

6. Traditional sign production generally adopts the way of carving+corrosion+colored paint filling, or laser carving, which can only make monochrome signs, but can't do anything about color patterns.

7. Repeated overprinter has high rejection rate and large color difference.

8. Skilled printing technicians with many years of rich experience are needed.

9. The demand for personnel is high, and the proportion of manual production is high.
