Apologies if this has been asked before. One way to make PCB's is to print the PCB template with a laser printer onto acetate. The acetate is then ironed to to plain copper clad PCB with a hot iron, the ink transfers to the copper and when set board is ready to etch.
My problem is, what viewing size gives actual size components? In PCBnew the 3D viewer can show top view or bottom view (copper) and then export as JPG or PNG image. Pressing F1 or F2 zooms in/out but I dont know which view ratio is actual size, can anyone help? After exporting the copper layer I can change it to black using Gimp but its getting component, pads and track sizes correct. Thanks in advance.
