Hi.
When I want to send file separation containing only spot colours, sometimes it comes with empty CMYK separations printed.
Lets say an artwork may be only one colour, so when printed the outcome should be just that colour, but instead I end up with 5 separations printed - the one I wanted to print plus cmyk bits all blank (empty pages with only registration pieces imprinted).
Neither on artwork nor separation preview there's no process colours whatsoever, so do any of You know what may cause this?
I'm using the same print template and it happens form time to time. (not a problem for me but my colleagues complain about it all the time).
