Hi again, I'm glad it was of help to you Christiane. I double-checked here on my files again and when checking the black text elements in the Preflight tool Enfocus Pitstop, it is reported as (as you say) "Gray" with 0% "Brightness". Although when using the Output Preview advanced function in Acrobat 7 Pro itself, the same elements are reported as "Process Black 100%" (when holding the mouse pointer over those elements). I don't do any color conversion in the Distiller settings.
I don't know why it is reported with different names in the two tools (maybe someone else can explain this?), but I am almost sure it wont create any problems in the printing process anyway. /Martin > -----Original Message----- > From: > framers-bounces+martin.aronsson=sonyericsson.com at lists.frameus > ers.com > [mailto:framers-bounces+martin.aronsson=sonyericsson.com at lists .frameusers.com] On Behalf Of Christiane Crety (CC) > Sent: torsdag den 9 november 2006 09:28 > To: Aronsson, Martin; Framers at frameusers.com > Subject: RE: CMYK/RGB conversion > > Thanks a lot, Martin! > You were right about my printer settings.
