Silk screen printing defects analysis - exposed

3. The exposed bottom (dry version)

The pattern on the fabric did not get enough color paste, the color was light and unclear, and the phenomenon that the bottom color of the fabric or the fine pattern was broken appeared as the exposed bottom.

Reasons: (1) Due to the deformation of the plate, the layout tilted away from the fabrics laid on the table, so that some of the patterns were insufficient (even produced desizing). 2 The speed of the scraper is fast, the pressure is small, the amount of slurry is insufficient, the scraper rubber is too hard, the cutting edge is too sharp, etc. It is easy to make the pattern insufficient. 3 pattern, part of the mesh plugging and color paste is too thick, so that the rate of color paste over the net, the fabric pattern on the lack of pulp. 4 Thick fabrics with coarse yarns or sparse tissue, due to the uneven surface of the fabric, the concave portion is easily pulped. 5 Partially low ink stamping pad or pad uneven, so that the fabric pattern on the lack of pulp. 6 The severe wrinkles of the fabric are not fully developed on the ink pad, or serious wrinkles are caused when the fabric piece is applied. The creases on the inside and the wrinkles on the sides of the printing cannot obtain the color paste, and the background color of the fabric is exposed.
