Copy color balance and density adjustment
(Manual adjustment)
a. General
The color balance adjustment (Manual adjustment) is used to
adjust the copy density of CMYK. This is used at the following situ-
ation. When the result of auto adjustment described above is not
existing within the range of reference. When a fine adjustment is
required. When there is request from the user for changing (cus-
tomizing) the color balance.
This manual adjustment is executed only for the color patch which
could not adjusted properly in the automatic adjustment.
If the color balance is improper, execute the automatic color bal-
ance adjustment in advance, and execute this adjustment for better
efficiency.

When, however, the color balance is adjusted according to a
request from the user, there is no need to set to the standard
color balance stated above.
If the color balance of each patch of the process black (CMY
mixed color) is slightly shifted to Magenta, it means that the
adjustment is proper. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color cor-
rection table in an actual copy mode. (When the color balance
target is DEF 1.)

The adjustment value is set in the range of (1 - 999). When
SIM 46-24 is used to adjust the automatic color balance and
density, all the set values of this simulation are set to 500.
To increase the density, increase the adjustment value. To
decrease the density, decrease the adjustment value.

Referring to the black/gray patches, adjust so that each pro-
cess (CMY) black/gray patch color balance of A - Q (MAX)
approaches the black/gray patch level as far as possible.
