Measure Toll Comparing

[FaroMojahedi]

I am trying to understand Measure Toll Comparing
What is an acceptable DE tolerance level when I compare my chart reading against the reference file?

It depends on the color software,device,proofing paper and the proofer ink you use~It`s hard to give a specific number

As well as the subject, the specific color itself, and the formula used to determine DeltaE.

Fogra has set tolerances for proofing in Europe. If that is what you mean. Average DeltaE is 3 or less and max Delta E deviation is 6 or less. And here Delta E is the "basic" Delta E. DE= sqr((L1-L2)^2+(a1-a2)^2)+(b1-b2)^2)
