Hi Carl,
I was able to get on Techniks www.techniks.com web site. I noticed they
recommend the blue PnP for high quality and wet PnP for hobby quality.  Have
you seen quality differences between the 2?  It sounds like you prefer the
wet over the blue.  Do you have any experience using a photocopier rather
than a laser printer?  Can you get good results from a photocopied image? I
need to spend $275 to get my laser printer back on line but can easily do an
inkjet print and photocopy it. thanks...
