Hallo zusammen,

ich benötige dringend eine Lösung, wie ich unsere Pantone Hausfarbe nachträglich in einen von der Druckerei ausgerechneten Referenzwert (CMYK-Wert) erstetzen kann.

Leider ist das Ersetzen des volltonwertes in Indesign nicht möglich, das Farbfeld kann nicht gelöscht werden, da die Funktion inaktiv ist.

Daher suche ich weitere möglichkeiten. Kann eine Farbe auch nachträglich über Acrobat im PDF ersetzt werden? (Das wäre mir lieber, da auch die Volltonfarben in eingefügten Grafiken direkt ersetzt werden.)

 

Vielen Dank und liebe Grüße

Hi,

you can't measure a physical paint colour in CMYK. BUT you can mearure as Lab.

Once you have the Lab measurement you can then use Photoshop to convert the Lab values to (the correct) CMYK colourpace for your print process. 

 

WAre tou really using a spotcolor printing process? So many users place Pantone values [which are the values of specially mixed "spot colour" inks] and just hope for the best when the colour is actually created out of CMYK inks.

 

Calculating the CMYK properly is the best way.

 

I hope this helps

You can use Acrobat to replace an existing spot color with a specific CMYK value. Go to Tools> Print Production> Preflight> Fixups (the blue wrench icon).

Find the existing Fixup named "Map spot color with a specific name and color values" To edit this Fixup, you will first need to duplicate it, use the fly-out options menu at the upper right corner of the panel, give the Fixup a new name. The attached screen shot shows a custom Fixup that converts all instances of PANTONE Red 032 C to yellow (0,0,100,0).
