| Confirm that your inkjet positives are truely opaque enough by recoating a screen, putting your inkjet artwork on one side and cover the other half of the screen with something known to be absolutely opaque. Expose with appropriate UV dosage. Both side should develop similarly, with the opaque sheet covered side washing out completely. If that side washes out fine, but the artwork side still has the "skinning" problem, then it would be logical that opacity of the ink jetted films is the issue. If both sides have the same skinning issue where the emuslsion should wash away, then the issue may be related to improper safe lights, excessive heat when drying the screen after coating. A test like this will eliminate/identify film opacity, or suggest something else in your process may be globally crosslinking the emulsion to some degree. | ||
