Other Targets
Create a corresponding Target CGATS file.
CMYK reference values have to be exactly as specified for a specific Target (second decimal place)
Tips
Some software that drives Instruments may build a Job Template using a 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 by Uploader will be auto-recognized. This requires a corresponding auto-recognition setting on Instrument/Target side.
