Hi Belinda, the Fogra requirements for Delta E tolerances for proofing (average of 4 and a maximum of 10) are according to ISO 12647-2:2004 (Process Standard Offset). We are recommending the same values in our "MedienStandard Druck 2004" (i.e. Media Standard Print, english translation available with next edition September 2005). Lower tolerances might be necessary for "critical appraisal" eg. of grey tones. Some customers require lower tolerances (eg average 2.5 or 3 instead of 4 for the patches of Fogra mediawedge www.mediawedge.com) but this is *not* the standard requirement (ISO).

The only thing I have been able to find is that fogra demand an average of 4 and a maximum of 10 based on their media wedge. Does anyone know what standards other bodies use, or have any relevant information on what would be an acceptable standard to expect and why (if possible)? Any help would be greatly appreciated.
