[ECI-EN] Delta E tolerances for proofing

Hi Everyone, I was wondering if anybody would have any information on what delta e tolerances different organisations are using with regard to the maximum and average delta e differences between a proof and a printed sheet, and also between proofs on a day to day repeatability basis. 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. Thanks, Bee Belinda Beckinsale Sinnott Bros Pty Ltd 4/85-91 O¹Riordan Street, Alexandria NSW 2015 Ph (02) 93539527 Fax (02) 93134597
