Altium schematic printing with NO background colour

(1/3) > >>

AlfBaz:
I cant seem to find a way to disable printing a background colour when printing schematics. The best I can see is setting the background to all white (all RGB values to 255) is this how you turn off background printing?

T3sl4co1l:
Err... huh...

I mean, I don't think there's such a thing as through-page transparency in PDF.  Objects on the page, maybe?

It's not impossible to suppose that one could actually format a page this way.  The printer would know what kind of media to use, based on the background: a 100% transparent background would be printed on acetate, a partial transparency might be printed on matte (translucent) stock, an opaque background on paper or other; etc.

But, I don't think this is done at all, and so, what's printed, is always an additive pigment (subtractive color) process.  And for that, by definition, white is the absence of all color, yup.

(Not to be patronizing, if this is a misinterpretation of your intent -- rather, just to entertain the thought of a document format that supports transparency literally everywhere.  :P )

More to the point, though -- let me guess, you've printed it on laser and found the disgusting dither pattern because Altium's default sheet is just slightly off white?  Yeah, I fixed that shit long ago on my templates... |O

Yes, that is how you turn it off. I think color 233 is White and 3 is black BTW.

T3sl4co1l:
The color palette is silly.  I never use it.  Always either the color picker grid (true grays, from #fff white to #0 black, are the bottom row), or custom 24 bit color on the other tab.

If in doubt, RGB doesn't lie :)

AlfBaz:
Thanks guys

and supposing weird things is how I've gotten by with altium/protel for years :)
