I tried my hands at calibrating newsprint using the G7 method,
yesterday.
Printed the P2P23xn target at press density. Used linear plates.
Measured
targets with DTP70 in ColorPort. Results fed into IDL : got the
weirdest
curves I ever seen. Took me a while to figure this out -- thank god
for
utilities like BabelColor's PatchTool (who provides invaluable
analysis for
any serious color work) every other row is "skipped" by the
instrument.
Bottom line, the whole test is unusable. Culprit: the design of the
target
which does not work for newsprint
You're blaming the target for a failed attempt to measure it? Isn't
that kinda' like blaming your car for your speeding ticket?
