Flat Screen Printing Machine printed technical points

   Flat Screen Printing Machine is a large -scale device in the printing industry. It has been widely used in our lives and work. Almost all things except liquid and air can be printed with Flat Screen Printing Machine. Flat Screen Printing Machine's printing and controlling the mesh distance when printing is one of the important factors for its quality. Flat Screen Printing Machine Silk Printing Union has adjusted the Flat Screen Printing Machine seal in order to ensure the quality of printing.

as follows:

    1. Flat Screen Printing Machine printing process

    If Flat Screen Printing Machine is printed when printing is high, the amount of ink is large, but the online version is easy to deform, so the scraping pressure should not be high. The scraping speed is often 60 ~ 200mm/s. The scraping speed is fast, the amount of ink is less, but it is not easy to block the net. Therefore, the ink of easy to block the net should be faster.

    Flat Screen Printing Machine should be printed on the printed route when printing. Select according to the flatness of the printers and graphics and texts. When the length of the scraping line is long and the ink consumes a large amount of ink, the amount of ink should be more or even scrapeed a layer of ink first, and then scrapeed.

2. Flat Screen Printing Machine before printing

    The degree of judgment of the degree of thickness: The degree of thickness is better to use the ink through the silk mesh, and there is no silk mesh or drawing on the printing surface. The degree of sparseness is on the silk network, and the ink can reach the mesh through the pores without dripping by its own weight. When the lines of printing are thin, the adjustment is thin, otherwise, the adjustment point is strong.

3. Selection of printed scraper for Flat Screen Printing Machine

Most of the materials used in the scraper are polyurethane. Polyurethane rubber scraper wear resistance, solvent resistance, and reflection elasticity is better. Its hardness is 60 ~ 80 Shao. The online version of the tension, the surface of the surface with good surface flatness should choose a high -hardness scraper. Conversely, low hardness should be selected.

When printed on the bearing of the curved surface, low spherical or flat, the width of the scraper should be narrow or width.

4. Flat Screen Printing Machine Selection before printing

The quality of the silk cloth is uniform with the diameter of the wire, the number of mesh is accurate and consistent, and the quality is stable.

The webmarks that are generally selected are 450 ~ 500 mesh. The seal with high fine lines and inks and poor absorption should be selected. On the contrary, the web version with a low number of networks should be selected.

   The location of the graphic and text on the version of the version and the size of the network should be determined according to the structure, size and the location of the graphic in the printed matter. If the design is not good, it will affect the quality of the wire printing and even cannot even. In addition, the graphic on the same seal is best printed with a web version. If it is divided into more than two online printing printing, the process will mostly reduce the qualification rate of the silk printing.
