Q: How is the Chromira SE Lab calibrated?

A:  Primary calibration of the Chromira SE Lab is done by printing a test image.  The calibration image has a series of gray patches ranging from white to black.  The gray patches are read with a densitometer that connects into the computer.  The Chromira SE Lab calibrates automatically from these densitometer readings.  The process is generally called “linearizing” the machine.
