I’m noticing when measuring the Fogra Media Wedge with our GM
EyeOne (rev2)
for proof verification that –
say for FOGRA27 max primary which has a 5 dE tolerance –
I’ll get a measurement of 5.44 – which is over the tolerance and
causes the
proof verification to fail.
But when I went back later and re-measured I got a new measurement
of 4.83 –
which is now under the <5 dE –
On what printer, ink, paper combo.
how long time after the printing was the first measurement done and
when was the second done? I am of course suspecting that the print
has changed between measurements so you can fully expect the same
measurements.
Have you tried making several consecutive measurements, with
calibration in between and without? This will give you a more
accurate picture of the instrument variability...
