Screen printing belongs to stencil printing, which is known as one of the four major printing methods along with flat printing, embossed printing, and gravure printing. Perforated printing includes transfer plates, hollow pattern plates, spray printing, and screen printing. The principle of stencil printing is that during printing, the ink is transferred to the substrate (such as paper, ceramics, etc.) through the holes in the stencil (made on the substrate of a paper film or other plate) under a certain pressure, forming an image or text. Transliteration printing, the simplest form of stencil printing, began in the late 19th century. This type of printing is made on specially made wax paper using a typewriter or iron pen to create wax paper graphic plates. Ink rollers are used to print on the wax paper plates, resulting in ideal printing effects on the substrate. The most widely used method in stencil printing is screen printing.
Screen printing is also the most common surface character process in our silicone products, among which silicone buttons and silicone toys use this process more widely. According to the character design, adjust the oil difference color, and then use the positioning fixture and screen to print the required characters.
The silk screen part of silicone products may have a convex feeling when touched by hand, and it needs to be carefully understood. Silk screen is a very important process in the silicone product industry. During the operation, it is necessary to pay attention to whether the surface of the silicone product is clean, the baking temperature and time after silk screen printing, and especially not to use low-quality silk screen ink or other materials to replace silk screen ink in order to save costs. This will lead to the occurrence of batch defects.
Strong printing adaptability, thick ink layer, strong three-dimensional sense, rich texture, strong light resistance, bright color, printing area, can be summarized as follows:
1、 Screen printing can use various types of inks. Namely: oil-based, water-based, synthetic resin emulsion type, powder and other types of inks.
2、 The layout is soft. The screen printing layout is soft and has a certain degree of elasticity, which is not only suitable for printing on soft items such as paper and fabric, but also suitable for printing on hard items such as glass, ceramics, etc.
3、 Screen printing has low embossing force. Due to the low pressure used during printing, it is also suitable for printing on fragile objects.
4、 The ink layer is thick and has strong coverage.
5、 Not limited by the surface shape and area size of the substrate. As mentioned above, screen printing can not only print on flat surfaces, but also on curved or spherical surfaces; It is not only suitable for printing on small objects, but also for printing on larger objects. This printing method has great flexibility and wide applicability.
