Eagle negative PCB output for printing

To make a PCB by using Dry Film photo resist, I need the PCB layout in negative mode. However, in Eagle PCB design software, I cannot print the PCB design in negative mode directly. After a few searches, I have found a good way to get negative films of my PCB designs from Eagle PCB software and it is very easy. There are  3 steps.

1. Click ‘CAM’ on the menu bar

cam-select

2. Select ‘PS_INVERTED’ as the output device and then select layers that you want to export

cam-output

3. Click ‘Process Job’ and it’s done!

 

The output is ‘yourfile.eps’ which is an encapsulated PostScript. You can use Adobe Illustrator or similar Vector based graphics applications to view/edit/print it.
