2. Color correction is complicated, and once the version is finalized, it cannot be modified;
3, the process is complicated and the production cycle is long;
4. Screen printing dots cannot be eliminated, and mass production is needed;
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. 1, suitable for any material, with a wide range of compatibility.
2, plate making is not needed, the printing speed is high, the cost is low, various output software can be used, and various file formats are supported.
3, equipped with professional color management software, can change color anytime and anywhere, no extra charge.
4, one-step completion, that is, printing and taking, to meet the needs of rapid proofing and finished products.
5, a large number of printing can be matched with template printing, saving time and effort.
6. Full-color images can be completed at one time, and the progressive colors completely reach the photo quality effect, with accurate positioning and zero rejection rate.
7. You don't need professional skills, you only need 30 minutes to master and make fine products.
8, computer operation, no personnel dependence, large upgrade space.
