My reason for approaching you is the fact that we can no longer get image setters positive here in Denmark so I am again using the Pictorico OHPs. Like earlier I often encounter measles in the highlights and midtones something I have not been used when doing other alternative techniques. However, searching the internet I came across your advice of using Kreene plastic instead of glass and got some Kreene from Boxcar Press. But after testing twice I still get the same result of measles. The plates we are using here are the KM73. Have you any idea of what could be the problem?<\/p>\n<p>Thanks in advance for any suggestion that might solve this.<\/p>\n<p>Best regards,<\/p>\n<p>Lene<\/p>\n<hr \/>\n<p>On Jan 27, 2012, at 6:20 PM, Jon Lybrook wrote:<br \/>\nHI Lene,<\/p>\n<p>Thanks for your message.

That step should be performed<br \/>\nwhenever exposing the plate using inkjet film such as Pictorico. The<br \/>\nfilm has a tendency to retain moisture. By drying it in a conventional<br \/>\nprint drier to remove the moisture you remove some of its tacky quality.<br \/>\nLikewise the light dusting of baby powder on the plate allows the film<br \/>\nto slide smoothly over the plate when drawing down in the vacuum frame,<br \/>\nhelping to give tight, continuous contact between the plate and film.<\/p>\n<p>Feel free to send me a scan of one of your prints so I can better see<br \/>\nwhat you&#8217;re talking about.<\/p>\n<p>Kind regards,<br \/>\nJon<\/p>\n<hr \/>\n<p><em><em>Hi Jon,<\/em><\/em><\/p>\n<p>Thanks a lot for your reply.<br \/>\nYes, I m usually drying the film about 10-20 min in a warm film\/plate drying cabinet and the baby powder I have been using for a long time.<br \/>\nBut I must admit that when testing the Kreene by exposing the attached steptablet I forgot to dry the film &#8211; probably because it is an old one having been dried earlier.<\/p>\n<p>By searching on the internet I have come across info about the new Pictorico ohp films having a tendency to give more problems &#8211; could this be correct?

This is good info.<\/p>\n<p>Looking closer at your sample test, I&#8217;m inclined to believe you have a contact issue with your film positive. I notice the percentages listed where the measles occur more prominently are slightly out of focus, which would suggest less than perfect contact. Look at 38% and compare it to 50% in terms of the relative sharpness. Likewise compare 96% to 100%. The perimeter is fuzzy.
