Default Re: UV Dry Film PCB technique - experiences to date.

Since last post, I've been playing with various programs to try and solve the size change program and my results --
1 - I design the PCB layout in PCB Express ,which lets me keep the maximum amount of copper by inserting a ground plane.
2 - copy ( Prntscr) to Adobe Photoshop Elements and remove colour, then Invert and auto adjust brightness/contrast to get best black/white contrast .
3 -Paste into Photodraw 2000 and use the resize facility to reset the board size to that in design, and also lets you reset the size of the paper you will be printing on, independent of the PCB size.
4 print from photodraw ,which lets you modify the size of sheet to print onto .
David -can you advise on how well the attached will come out ?
OH-BTW- I did try greaseproof paper .On it's own in my printer, it wouldn't feed in as it's too thin, and with a sheet of A5 ,it's too shiny, so that's another idea up the swanny.
