I recently acquired a NuArc thanks to a good friend. The bulb is essentially new. I am using a contact frame on top of the vacuum glass rather than the vacuum. While testing to determine settings for printing my negatives an unusual problem arose. Regardless of process if I print on Arches Platine a dot pattern appears in the mid and lower tones which is similar to a dot screen and very sharp. It does not appear on linen stationery or Stonehenge. It has nothing to do with the glass in the frames as they are the ones I have used for 50+ years. I have not tested my other papers yet. Has anyone else experienced this problem?

Thanks,
Jim
