Silk Screen Printing Rickets Analysis - Uneven Color Patterns

5. The shades of shades are uneven

The pattern of the same color on the fabric is inconsistent in color and shade. When the pattern area is large, it shows an irregular pattern of scattered flake or horizontal color and a regular longitudinal color pattern. The patterns are called uneven shades of shade.

Reasons: 1 When the printing operation, the speed and pressure of the scraper run inconsistent or uneven with the slurry, so that the pattern of the amount of slurry to give more or less, the fabric of the pattern of more pulp color darker. 2 When the running squeegee bounces or slightly lifts, the residual paste on the pattern surface passes through the mesh to the fabric, resulting in a darker horizontal color pattern. (3) The blade of the rubber blade is not evenly curved, and the pressure and the amount of slurry are not uniform when the blade is scraped, so that the pattern on the fabric exhibits a regular, inconsistent longitudinal color pattern. (4) The local low-convex or printed plate layout of the printing station is far from the fabric on the ink pad, which can also cause the pattern to be lack of pulp and light color.
