This completes the EX7750 calibration process.
Calibrating from the Control Panel using VisualCal
VisualCal is a calibration method that allows you to calibrate your printer to a color
output standard defined by the manufacturer. The calibration calculations performed
by the controller software are based on a series of values entered on the Control Panel.
The values used in the calculations are determined by evaluating toner densities and
color combinations produced on two specially designed calibration pages printed from
the Control Panel.
Limits and 30% Match
The first VisualCal page, “Limits and 30% Match,” provides the basis for calculating
the most acceptable luminosity (brightness) of the toners. This page consists of rows of
CMYK dots in a graduated range of toner densities.
The variables needed to recalculate the density of the colored toners are determined by
identifying the leftmost dots that can be fully distinguished against their fields in each
row, and sequentially entering their corresponding numeric values on the Control
Panel. The variable needed to recalculate the
luminosity of the toners is determined in a
slightly different way—you identify the black dot that best matches a 30% dot gain
field. When all values have been entered, the printer’s toner density and luminosity
settings are recalculated.
