Exposure and washout times?
- Hi everybody, well the Heidelberg is up and running, I just need a little
information re the photopolymer plate that I have had to make for this
particular job, can somebody tell me what exposure times they use under UV
lights, I use a upright plate maker with a bank of 6 UV tubes about one and
a half to two inches away from the image, and expose it for around 3
minutes, and wash it out in a wash out tank for approximately 8 minutes.
The smaller print doesn't tend to come out very well the rest of it looks
just fine, I am wondering if my washout time is too long or I haven't
exposed it long enough or too much, can anyone help?
