-A part of printed surface becomes blebby with a rough appearance like that of sharkskin. It occurs due to unsuitability of colour paste viscosity and screen mesh and uneven adhesion.
-A printed motif blurs and as a result the outline of the design appears unclear. This may due to - the viscosity of the colour paste is too low, the concentration of the dyestuff in the print paste is too high and the amount of colour paste printed or the amount of hygroscopic agent used id too high.
Staining during steaming
-Stains are transferred when a poorly washed printing table is used, the printing cloth is piled up after insufficient drying or a part of the cloth touches another during steaming
-Colour tone gaps appear horizontally at the same distance from each other. This may be to bad screen frame, a poorly installed squeegee and uneven squeegee pressure
Poorly adjusted screen
-Disfigured designs or overlapped motifs. This is due to the belf drive and point adjustments, etc are not properly done
-Designs printed are a little off. Disfigured designs, poor engraving, pooer cloth adhesion, etc are the cause of this problem
-When the print bends or is of different with in different areas
-Stains or unevenness due to the drops. Drain(condensed water) or drops are the cause.
