Printing plate

Stenograph bar is used to provide proper exposure conditions for PS plate and film, and can be used to detect the sensitivity of the developer for maintenance purposes.

Switzerland Ugra--imported print control bar, UGRA print control bar is the printing plate development and exposure control bar developed by the German Institute of Printing and Copying Technology, is the world's most advanced control bar

Ugra plate control wedge (PCW) The 1982 print control bar features five functional segments, each with its own distinct function.

The first paragraph: used to control the development of the plate, you can also check the exposure of the plate;

The second paragraph: Microcoils are used to control the exposure time;

The third paragraph: network segment, 10% network point to 100% field 10 blocks. Used to check exposure development, also used as a benchmark for printing characteristic curve measurements;

The fourth paragraph: Fine network lines along different angles allow the printer to visually inspect the printing machine for dot distortion and ghosting;

The fifth paragraph: Fine network segment points are 0.5% to 5% for positive images and 95% to 99.5% for negative images, which are used to check if there are any dot reductions in the printing process.

Print control strip

The German FOGRA--Printing control strip can not only check the dark tone, the halftone dot enlargement, but also can check the dot distortion and the ink overprinting.

BRUNNER Brunel

Switzerland Brunner-Brunner color signal strips, added printing quality control strips, and increased the ink control section and ultra-fine measurement section, can not only control the quality of the printing but also control the printing quality.

Using the point shape change of the hyperfine segment, it is possible to visually judge and check the deformation of ghosts and dots, etc.
