Homebrew PCBs

A while ago I tested many different inkjet transparencies on 
several printers (Epson 660, HP 640 Deskjet) and found 
surprising large differences in quality of the prints. You 
can get very opaque and solid filled prints with and Epson 
660 (or any model with same black ink composition), and 
Epson transparencies. I have not tried the CLASSEN TRON 
XEROMAT I Universal. The black ink in the Epson Photo 1200 
may be compatible with these transparencies. One day I'll 
get around to making a web page   explains inkjet and 
transparencies for producing photomaks.

One thing I have learned is that the ink and transparency 
MUST be compatible for good results. Looks like you found 
one such combination, Thanks Carsten for showing us.
