I've been having an issue on projects whenever I am printing a fine, straight line - let's say between .75pt and 1pt. I get this subtle wobbly distortion (see image), which is actually pretty noticeable when viewed at arms length. I looked at the film and it's perfect, so the distortion must be occurring during exposure or washout. Upon further inspection of the burnt screen, it appears that the distortion is visible in the stencil. So the question is, how did it become distorted during the exposure or washout. I have a vacuum exposure unit. I am using a 255 screen. Could it just be a characteristic of the mesh that I just haven't noticed before, that "just happens" with screenprinting. Anyone have this issue before? Anyone know what is causing it? Any ideas for fixing the problem.
Thoughts would be greatly welcomed!
