      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?


      Regards,
