Setting Up the Gray Balance
PowerColor’s Gray Balance table should be adjusted for each press environment
you intend to use. PowerColor provides a number of easy-to-use tools for cus-
tomizing tables for different ink or printing conditions. To bring up the Gray
Balance window (see Figure 5–3) select Gray Balance in the Correction menu.
The gray balance table shows the corresponding Magenta and Yellow values for
Cyan dot percentages in increments of 5%. Depending on specific press character-
istics, you might, for example, want to make sure that at a 50% Cyan dot, the
Magenta channel is not too strong. This table could be used to reduce the
Magenta value to, for example, 39% by typing 39 in the Magenta field at Cyan
50%.
Note: Gray Balance affects only the reproduc-
tion of the neutral areas. It does not affect the
reproduction of hues.
