Negative Photoplot

Hi Folks!

Can someone explain me how to do an home-made negative photoplot of PCB with P - C @ D 2**2? :(

I can make positive photoplot without problems.
I used a HP laser printer with a transparent sheet and it works fine for positive.
For negative I've tried many color options unsucessfully. I search for any option to "revert" the PCB but I not found it.

Please, help.

Thanks in advance.

Negative Photoplot

If the artwork is on PDF, OPEN IN 100% SIZE, select the PCB area and Copy and paste it on to paint software found in windows.

Now in the Paint, click- Image- Invert colors.

At this stage the image becomes Negative. -- Save it as a bitmap, with suitable name.

Note: at the same time you can also Flip Horizontal or Flip vertical for getting a mirrored image if you need one.

All the best.
