END_DATA
Download sample file for X-42, B-42 or I-42 Target
Virtual_Colorimeter sample file
Other Targets
Create a corresponding to Target CGATS file.
CMYK reference values have to be exactly as specified for specific Target (second decimal place)
Tips
Some software that drives Instruments may build Job Template using list of patches - in most cases,
a CGATS file can be uploaded.
If your software can manage metadata:
PRESS_NAME "auto-recognition"
PAPER_NAME "auto-recognition"
you may use it for the auto-recognition feature. Files uploaded to user root FTP directory will be auto-recognized. This requires corresponding auto-recognition setting on Instrument/Target side.
Sample Instrument: Color Muse
