Hi!

Can anyone tell me why the holes on my PCB Layout Diagram are filled in in white and not black like they would be on a conventional layout diagram in a book, magazine or service manual please?

I have set the "Top Silk" to Black and the Background to White and everything comes out in pdf as I expected except the holes are white and not black!

Also, is there a means of printing the tracks only in grey like they would normally be in a magazine layout diagram or service manual layout diagram?

1) Because you have set the Background colour to White and you are effectively "seeing" through the holes. The holes will appear in the background colour. If you choose a Black background, White Board (PCB edge) and check the "Print Background" box, you'd get a Black PCB with White edges and Black holes.

2) But, the pcb substrate will appear White in your example, -which, although "as you expect", isn't strictly correct either (should perhaps be FR4 "green"?) but this facilitates pcb design -which is the objective of the EasyPC package.

3) You can specify light/mid/dark "Grey" (or any other colour) as the copper colour in Design Tech and it will print out as grey, -if the "All Colours Black" check box isn't ticked. As for "printing the tracks only in grey like they would normally be in a magazine layout diagram or service manual layout diagram", this refers to the (bad) old days when commercial printing was usually restricted to Black/Grey on White (and sticky black crepe paper tape was universally used for pcb design!) before full colour Desktop Publishing/Printing took off . Modern publications usually have "full colour" pcb layouts.

edrees is quite correct but to expand on that, when you're setting up the design colours, you can save them to a named colour file. That gives you the ability to save your colours, set up your preferred printing colours, save those as well, print, then restore your original colours. The 'printing colours' will then be available to load in the same way for future designs.
