Calibration overview

Obtaining the most satisfactory print quality on your printer depends on a number of issues. One of the most important issues is steady toner density. Toner density is affected by many factors such as heat, humidity, and service settings. Toner density also tends to vary over time. Such variations cannot be totally eliminated, but you can perform the calibration process to compensate for them.

The calibration process consists of creating calibration tables that are mapped to a specific media type, and screening method.

You can create calibration curves using either of the following options:

●Off-the-glass calibration: Enables you use the scanner platen to create calibration tables.

●X-Rite i1 spectrophotometer: Enables you to print a color chart, scan the streams of color patches in the color chart, and create a calibration table based on the scanned measurements.

The CX print server uses the data in this table to compensate for the differences between the actual, measured density level and the target density level.

You should create calibration tables in the following instances:

●Every 24 hours, to compensate for potential variations in toner density

●When you use a new paper stock

●When prints show “color casts”

●After machine maintenance or hardware changes

●If there are drastic ambient changes (temperature and humidity)

In the job parameters window, under Color > Calibration, the Linked option is selected by default. Any job that meets the media attributes and screening that you selected during the calibration process will automatically be mapped or linked to that calibration table. When you send your job to print, the calibration table that is linked to the selected media type and screening is automatically used for printing the job.
