Packaging material printing process 01
1. Screen printing
Utilizing silk screen as the plate base, the screen plate with pictures and images is created through the photosensitive plate making method. Screen printing involves five essential elements: screen plate, scraper, ink, printing table, and substrate. By applying ink onto the graphic part of the mesh on the screen printing plate while preventing it from reaching non-graphic areas of the mesh, a distinct concave-convex effect is achieved after printing due to the layer of ink. Regular cylindrical bottles can be printed in one go using silk screen printing; irregular shapes may incur additional charges. Color selection also incurs a one-time expense. Self-drying ink and UV ink are two available options for this process. Self-drying ink tends to fade over time but can be easily wiped off with alcohol, whereas UV ink provides an evident concave-convex texture that is difficult to erase.
2. Hot stamping
Also known as hot foil stamping or hot press transfer, hot stamping is a decorative print technique where a metal plate is heated and foil is applied onto prints to create gold text or designs. This process utilizes electrochemical aluminum foil as its primary material for achieving special metallic effects by transferring an aluminum layer chemically onto the surface of substrates.
3. Water transfer printing
It is a way to print the color pattern on the transfer paper on the surface of three-dimensional products by using water pressure. The printed lines are inconsistent. And they are more expensive.
