Subject: Qualifying a CMYK Press Profile
'I'd like to hear from the experts regarding qualifying a CMYK press
profile
for proofing and separations.
What do most of you look for when deciding whether or not a given
profile
is acceptable?'
Hi James,
You may view a press profile Subjectively - Does the profile render
pretty pictures, good grey balance, saturation, smooth vignettes, etc.
etc.
and
You may view a press profile Objectively - through colorimetric &/or
spectral measurements.
However, regardless of the 'Quality' of output from your proofer when
using the press profile, the proof will only be accurate if the press
remains in the same state as when the profile was created.
Therefore, it is essential to establish the condition of the press prior
to profiling and ensure that this condition is repeatable time after
time. i.e. No mechanical instability, same dot gain characteristics -
which is a function of the plate type and physical press set-up.
Drop me a line 'Off-List' if you want a little more info.
Regards,
Stuart Peel
