CCD screen printing machine: screen printing machine technical characteristics and printing elements

　　First, the technical characteristics of the screen printing machine

　　1. Screen printing machine can use a variety of ink types. Namely: oil, water, synthetic resin emulsion, powder ink and other types.

　　2. The layout is soft. Silk screen printing machine layout is soft and flexible. It is not only suitable for printing on soft materials such as paper and cloth, but also suitable for printing on hard materials such as plastic, glass and ceramics.

　　3. Screen printing machine impression is small. Due to the low pressure used in printing, it is also suitable for printing on fragile objects.

　　4. Thick ink layer, strong coverage.

　　5. Not limited by the surface shape and area size of the substrate. Silk screen printing machine can print not only on a flat surface, but also on a curved or spherical surface. It is not only suitable for printing on small objects, but also suitable for printing on large objects, with great flexibility and wide applicability.

　　Two, the printing elements of the screen printing machine

　　1. Screen printing machine board

　　Three methods can be used to produce screen printing machine: direct coating method, direct film method, indirect film method. According to the type of substrate, plate making process should fully consider the screen printing machine tension, mesh number, plate film thickness, screen frame size and other important parameters. To combine the type of ink to choose water - based or oil - based photosensitive adhesive.

　　2. Screen printing ink

　　Screen printing machine can choose solvent screen printing ink, UV screen printing ink and a variety of functional pulp, screen printing ink should be based on the material of the substrate, the test selection.

　　3. Screen scraper

　　Screen printing machine scraper is the source of screen printing machine, plays the role of transfer ink and leakage ink. Rectangular sections are usually used for planar substrates, and triangular sections are usually used for curved substrates. CD can be regarded as special scraping, soft scraping for rough surface, hard scraping for smooth surface.

　　Step 4: Jig

　　In order to ensure the accuracy and consistency of the overprint position, it is necessary to make a stable and good logo fixture. The cutting plane of the highest point of the plane fixture is parallel to the screen surface, while the bending fixture requires that the shaft end of the transmission gear with a circular diameter be equal to the circular surface of the bottom plate.
