I have been using Kicad for about a month for my project. While finishing up the 2 layer design, I wanted to print out a negative plot on a butter paper.
I tried the plot/pdf option and print option from the file menue.
In the plot-pdf option, the output PDFs were on different scales so the printout was not accurate as all footprints changed because of no scaling.
In the print option, there is no negative plot option, so I used two softwares to try and invert the content inside the edge-cut. I used gimp and inkscape. In both the softwares, I faced the scaling issues as well, while exporting the inverted layers.
The not so good final way I resorted to, was to scale the printout at the Ctrl+P stage, by taking the print of wrongly scaled top and bottom from plot/pdf option and print(+ gimp/inkscape) option, measure how much it was off by, and then decide the scale, and input it at Ctrl+P.
Is there anything that I am missing?
