- Thread-topic: Rendering Intent
Most of the time when we print our guide prints (inkjet proofs) for
reproductions of paintings, or other artwork with a full range of color, we
use the relative colorimetric rendering intent and achieve a pretty good
screen to print match. When printing old master prints and drawings (most
often on old, yellowed paper) we find that we achieve the best guide print
if we use the absolute colorimetric rendering intent. When we do this, the
screen to print match is okay, but not as good as with paintings. I believe
the reason is because works on paper are more monochromatic and near neutral
which is a region where some funny things can happen in ICC profiles. In
principle, color is encoded device-independently, but in practice, that same
data can be interpreted in dramatically different ways depending on the
rendering intent used.
The problem is that when we send our file, with guide print, to the printer
we do not indicate which rendering intent was used to make the guide print
(it seems to me that this might be specific to our printer or our profile,
so I¹m hesitant to dictate a rendering intent). Often, at the printer they
will use a different rendering intent than we did and the results can
sometimes show a significant difference.
My question is whether there is some convention regarding rendering intent
for proofs/printing that people are using? Would you recommend that we
should dictate what rendering intent to use (or at least indicate which one
we used)? The nature of the artwork that we are reproducing makes it
necessary for us to use different rendering intents, so we can¹t standardize
on just one. I was wondering if others use multiple rendering intents and
whether or not you indicate what was used when you send files out to be
printed?
