Various Printing Types 2
Hot stamping, commonly known as "hot stamping", has a long history in my country. It refers to the words and patterns of materials such as colored foils hot stamped on the first or fourth cover and the back of the hardcover book cover, or the titles or patterns of various convex and concave books are imprinted by hot pressing.
Flat screen printing
The printing die is a polyester or nylon screen (pattern) fixed on a square frame with a hollow pattern. The color paste can be penetrated at the patterned part of the flower plate, and the mesh is closed with a polymer film layer at the non-patterned part.
When printing, the pattern plate is pressed against the fabric, the color paste is placed on the pattern plate, and the scraper is used to scrape and press back and forth, so that the color paste penetrates the pattern and reaches the surface of the fabric.
Flat screen printing has low production efficiency, but has wide adaptability and flexible application, and is suitable for the production of small batches and multiple varieties.
Screen printing is to stretch silk fabric, synthetic fiber fabric or metal mesh on the screen frame, and use the method of hand-carved paint film or photochemical plate making to make screen printing plate.
Modern screen printing technology uses photosensitive materials to make screen printing plates by means of photolithography (so that the screen holes in the graphic part of the screen printing plate are through holes, and the screen holes in the non-graphic part are blocked. live).
During printing, through the extrusion of the squeegee, the ink is transferred to the substrate through the mesh of the graphic part to form the same graphic as the original.
Screen printing equipment is simple, easy to operate, easy to print and plate making, low cost, and has strong adaptability.
Screen printing is widely used in common prints: color oil paintings, posters, business cards, binding covers, commodity signs, and printed and dyed textiles.
