Hi!
I'm going to calibrate and profile wide format solvent printer: Roland XJ-740.
RIP software i'm using (VersaWorks) has ability to calibrate printer... but
i want to disable it (by setting linear curves) and use Argyll all the way
through (i want profile with calibration)
This is my calibration & profiling procedure:
=== Calibration ===
1. targen -v -d4 -s50 -e4 -f0 Roland_XJ-740_calibration
2. printtarg -v -ii1 -R13 -pA4 Roland_XJ-740_calibration
3. printing "calibration test chart"
4. chartread -H Roland_XJ-740_calibration
5. printcal -v -p -D"Roland_XJ-740 calibration" -i Roland_XJ-740_calibration
=== Profiling ===
6. targen -v -d4 -G -g11 -s11 -f1323 Roland_XJ-740
7. printtarg -v -ii1 -R13 -pA4 -K Roland_XJ-740_calibration.cal Roland_XJ-740
8. printing "profiling test chart"
9. chartread -H Roland_XJ-740
10. colprof -v -D"Roland_XJ-740" -qm -S sRGB.icm -cmt -dpp Roland_XJ-740
11. applycal -v Roland_XJ-740_calibration.cal Roland_XJ-740.icm
Roland_XJ-740_calibrated.icm
Hence i have a couple of questions:
A) Are above steps right? Maybe You have some comments or advices...
B) Do I have to additionaly apply calibration file to the created profile (step
11) or
"-K Roland_XJ-740_calibration.cal" in printtarg (step 7) sufficient?
In other words... by using -K option is calibration file passed to colprof
or it is used only while printing "profiling test chart" (step 8)?
C) Is colprof smart enough to use ink limits from the calibration file or I
have to give them to colprof explicitly?
D) Is setting up ink limits at RIP required (for example total ink limit:
250%)?
or limits contained in icc profile are sufficient (while RIP individual
limits are set to 100%, total ink limit: 400%)?
Best regards
Michał
