An interesting aside, we used multiple Epson printer models (4800,
4880,
etc). Used Bill's 5202 patch target. Read three targets from multiple
printers into the iSis. The Epson 4800's had an average deltaE 2000
of 0.81!
The 3800 was a fraction over 1. Even the 2400 had very low average
deltaEs.
No offense, but that's not usually good enough for most contract
proofing applications. An average dE2000 of .81 is probably closer to
1-1.2 dE76 and doesn't address peak dE numbers. With an average of 1
dE, you'd typically see max dE values of 3-5. For contract proofing,
I would expect to hold multiple printers to < .75 dE76 and < 2 dE
max. Perhaps fine art/photo printing doesn't have quite those sort of
tolerance requirements but I know that one of the goals of fine art
printing is to be able to print something today and then print the
same thing months from now and expect them to match. I'd be curious
as to what fine art printers consider to be an acceptable dE tolerance.
