"What kind of DeltaEab number are you talking?"

Max deltaE CMC: starts around 2.5 (day after profiling), then creeps up to 4-4.5.
Ave deltaE CMC: around 1 (as high as 1.4)

Max deltaE Lab 1976: about 4.5.
Ave deltaE Lab 1976: around 1.5

(This is on 373 patches (Monaco target) imaged daily. All readings are compared to the target that was imaged immediately after profiling.)

Dear Walter

The above would have me running for cover, but then I may be reading different samples and getting a different picture. Could you tell me what you are measuring for these number please?

Cheers

Richard
