Hi,

I need some help with the overprinting and knockout functions.

I made a flyer that has orange headlines on a black background. To be
able to print it in the print shop I enabled the color management
system, used a color profile and created all colors in the cmyk color
space.

Then I exported the flyer to PDF X-3 and checked the lookout in Adobe
Acrobat reader. The Problem was, that I couldn´t see the orange text.
I could only see the black background of the orange headline.

I played around a little bit and found out, that everything works, if
I change the overprinting option of the text box to knockout.

Because knockout seems not to be the default option for text boxes,
I´m insecured a little bit. Is knocking out the text the right option
for printing light text on dark background?

Shouldn´t it be possible to overprint the black background with other
colors? I´m not a professional so I don´t know how this really works
in the printer afterwards but I read something about artefacts in some
situations with one of these options.

I would be pleased if you can clarify this a little bit for me because
I want to print the flyer in a higher quantity and the need to print
the flyer again would not be so cheap for me ;)

Kind regards
Clemens John
