I find all affordable color lasers to have inconsistanct color over time, due
to humidity and other factors. The solution I typically leave with clients is
ColorVision's ProfilerCMYK (or ProfilerPRO if they have other devices to
profile as well), with directions on how to use the scanner based profiling
method, and instructions to reprofile every morning, or as needed. The
process only takes a few minutes, since the scanner is used to read the
target patches. While the accuracy is reduced by the use of a scanner instead
of a spectro, laser toner and laser paper are pretty good for scanner
readings, and I have often set up the shop's scanner with a good profile as
well, which simplifies things even further. The laser profile is saved with
the exact same name each day, and used to convert images on the fly (and not
save them), rather than to hard convert and save images, to avoid problems
with varying profiles under the same name. Ironically this method, with a
$200 software package and no new hardware, often outproduces the most
expensive custom profiles (since it reflects the *current* state of the
device), and is far more likely to be used than an expensive in-house
spectro-based package (since it's simple and fast).
If your RIP can't convert on the fly color server software would be in
order... and if you need to hand out a CMYK profile for preconversion, rename
an average day's profile as LaserCMYKStandard.icc or some such, and let the
software convert files from that profile to the profile-of-the-day, which
should have similar black generation setting, but with corrected densities.
