As I've mentioned before. we are a pre-press provider for publishers and
printers worldwide. We use an Indigo Press as a proofer and 95% of the time
print/proof is on the actual press stock. This paper is mostly supplied to
us by the printer themselves. As I look into our press room I would say
that I probably have about 150 different papers; three quarters of which
are uncoated stocks heavily laden with OBA's. Using the i1Pro2 in M1 mode I
have measured all the papers.
I cannot possibly have 150 different colour managed Hot Folders with
individual colour tables based on each stock we proof on. (It would be a
nightmare to build and control). I want to group papers into groups based
on LAB M1 measurements. Example: 94, 1.0, -9 might be one group. My colour
managed Hot Folder would have a colour set up created from 94, 1.0, -9 and
I'm wondering if there are any "rule of thumb" tolerances I could use for
my groups. Say Group 1 has been set up with 94, 1.0, -9 and my tolerance is
L+/- 2, *a +/- 1, *b+/- 2. I could now group all papers that fall within
those specs. I realize colour would not be an exact match for each sheet;
but should be close enough to allow a printer to "match" the proof.
Has anyone done this and does anyone know if my tolerances are out of
whack? My +/- 2 could become quite a large tolerance if ..
94, 1.0, -9
92, -1.0 -7 Is this to large of a gap?
Any help would be appreciated.
