Re: Test Targets

2011-05-01 by Bob

Hi Betho,
Thankyou for sharing with the group. The test image is a good one. It shows that my printer does much better horizontally than vertically.

I processed your Gerber file into a Tiff at 1000 dpi and printed it with Innovue to a file. I looks like it is being printed at 360 dpi.

I Tried another image printing program yesterday called 'Irfanview' which also prints at 360 dpi. So I still don't have anything that can do a better job of printing.

Bob
