Calibration
One of the most important issues in obtaining satisfactory print quality is
steady toner density. Toner density is affected by many factors such as heat,
humidity and service settings. You can perform a daily calibration to
compensate for these factors.
The calibration process corrects the printer colors by measuring their
density and creating calibration look-up tables. The Spire CXP6000 color
server uses the data in these tables to compensate for the differences
between the actual, measured density level and the target level, the target
density.
You should perform calibration in the following instances:
•
When you use a new paper stock
•
When you use a different screening method
•
At least once every eight hour shift for every combination of paper
stock and screening method used
•
When prints show “color casts”
•
After machine maintenance or hardware changes—for example,
replacing a “charge corona”
•
On drastic ambient changes (temperature and humidity)
Important: Perform a different calibration for every combination of media and
screen type you are going to use for printing. When calibrating, always use the
same media that you intend to use for printing.
Tip: You can set a reminder to remind you to calibrate the Xerox DocuColor
6060 Digital Color Press. For more information, see Calibration Reminder on
page 427.
