Many silicone products need to be printed, and the printing methods are roughly divided into the following types: silicone screen printing, silicone pad printing, silicone color printing, silicone transfer printing, and silicone film printing; the following Rongjin silicone printing and processing custom manufacturers separately treat these types of silicone A brief introduction to the printing process and methods, please correct me if it is wrong.
Silicone silk screen: silk screen is the first printing method. Silk screen printing requires a screen, so it is also called screen printing. Generally, the screen printing ink will be thicker and brighter, and the printed pattern will have a three-dimensional effect. Silk screen printing can also print relatively thin lines and is also suitable for large-area printing. The disadvantage is that the printing is too slow and the productivity is not high, because it is scratched by hand, and some patterns will be a little ghosted if you don't pay attention to it. Screen printing can only print one color at a time. If you need to register, print the first color first, then bake it, adjust the position of the screen, and then print the second color. Recommendation: silicone screen printing buttons
Silicone pad printing: The pad printing is made of steel plate, which is printed by machine. The principle is to engrave the logo on the steel plate. When the pad printer scratches once, the ink will gather in the engraved area, and the silicone head on it can be printed on the product by dipping the ink. The advantage of pad printing is that the printing speed is fast, and it is possible to register several colors of the logo at the same time. The disadvantage is that compared to silk screen printing, the ink is slightly thinner and not so bright.
Silicone color printing: color printing is also called digital printing, digital printing, cmyk printing. The principle of color printing is the chemical reaction between silica gel ink and silica gel itself, so the background color of color printing products is generally required to be white, otherwise the color of the color printing pattern will change color. If the background color of the color-printed product needs to be other colors, a layer of white background is required, that is, a layer of white ink is printed with silk screen or pad printing first. But because there will be dust during the printing process, when doing color printing, there will be small dust particles on the surface.
Silicone transfer transfer: transfer is divided into thermal transfer and water transfer. Rong Jin will focus on thermal transfer below. Silicone thermal transfer can print logos in many colors, which is a way of secondary printing after the product is finished. It is similar to the film printing principle, similar to a layer of film paper printed on the product. The edition fee is a bit more expensive, and there is no requirement for product color.
Silicone film printing: The film printing is to directly press the pattern on the product when making the product, without secondary processing and printing. The film and paper plate fee is more expensive! The delivery time for film printing is faster for large orders!
