3 Calibration

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, paper weight, and screening method.

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

●Inline spectrophotometer: Enables you to automatically calibrate and create profiles for your digital press. The automatic calibration tool allows you to create calibration curves for several screening types.

●Calibration wizard: The Calibration wizard guides you through printing a color chart, scanning the streams of color patches in the color chart, and creating 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 the actual, measured density level, and the target level, the target density.

You should create calibration tables in the following instances:

●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)

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