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

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

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.
