I'm looking for an article that discusses the variable accuracy &

with Ink Jet printers when calibrating and profiling these devices in a
color managed workflow.
Well, if you read a continental European language, the answers you
want are for instance here,
FOGRA Forschungsbericht 10.037, 'Eignen sich Low-Cost-Farbdrucker und
Softproof als Andruckersatz'.
If you don't read a continental European language, the short and
sweet answer is that heat-based digital color printing systems (dye
sublimation and color lasers) are no match for a self-calibrating
PostScript inkjet like the HP 5000PS which is an interesting teacher.
If you have an automatic spectrophotometer and the MeasureTool module
of ProfileMaker, or the older developer-oriented ColorLab, it's easy
to check device drift. Just print a small testchart across the format
fifty or a hundred times, measure up, and compare.
Visually, with dye subs you may get streaking in transitions between
areas of solid color. Bruce Lindbloom has a neat test file to help
you check for this on the Picto site. With color lasers you may get
ghosting in areas of solid color.
