Stock Management and Calibration

Color DocuSP systems achieve high-quality color results due to
an efficient and flexible stock management model. Stock
associations, calibration, and characterization are important
processes used for stock management.
Calibration is a process that is used to return the print engine to
a known standard to achieve and maintain consistent color
quality for each stock or color group and halftone.
DocuSP calibration uses the X-Rite DTP41 Spectrophotometer
to measure and adjust the gray balance of the CMYK color
output. You should calibrate the X-Rite DTP41 daily. Refer to the
DocuSP on-line help for complete calibration instructions.
Calibration is generally performed once for each color group/
halftone combination. If you do not use a specific halftone for
printing, you need not calibrate it.
Once a stock is calibrated, DocuSP saves that calibration and
automatically selects the latest calibration for the stock when the
stock is required by a job. DocuSP can save up to five
calibrations per stock. These saved calibrations are assigned to
the color group in which the stock resides, for use with any stock
within that color group.
Characterization is the process of creating a destination color
profile for stocks. Stocks have different characteristics such as
coated and uncoated, color, and weight which impact how color
appears on the sheet. For most users, characterization is not
recommended for a new stock; instead, you should place the
new stock in an existing color group.
DocuSP comes with 3 pre-installed color groups, containing
Xerox Qualified Stocks. Xerox Qualified Stocks are automatically
part of one of the pre-installed color groups and have a
destination profile pre-assigned to them; therefore, they do not
require characterization.
