thanks for the reply,
You are absolutely right about transparency making a difference.
From the 8 brands I've tried, each one behaves different. And
yes, the best transparencies are the ones the manufactures
recommended. So it not just all to do with marketing and sales.
It seems obvious manufactures will optimize their ink and media
compatibility. I'm will still be testing non OEM brands.
However , what I have found is the recommended printer setting
for transparencies is not the best choice for PCB photomasks.
For the Epson Stylus; "Photo Paper", at 720 dpi
The Cannon seemed to print best on "High Resolution Paper" mode.
Th. Epson stuff still wins with darkest and no pin holes.
