Executing Special Functions Printer Profile This selects the profile to suit the type of document. Generally, you will use the Recommended by Canon setting. Recommended by Canon lists the color features that are suitable for the BJ cartridge, paper size, print quality, halftoning, etc. Gamma Correction Gamma Correction enables the adjustment of halftone contrast between perfect white and perfect black. If you want to adjust the contrast, place a check in this box and move the slider left or right to set a value. When Gamma Correction is not to be performed, clear the check mark from the checkbox. Color Balance The color intensity is set separately for cyan, magenta, yellow, and black. The color intensity is adjusted by dragging the slide bar for each color to the right or left. For example, if you feel that the blue (cyan) component is too strong, drag that slider in the negative direction (to the left). On the other hand, if you think that the blue (cyan) is too weak, drag the slider in the positive direction (to the right). Once you have made the adjustment, the balance of the four colors changes and the overall color tone changes as well. It's a good idea to make such adjustments in very small steps. Density Moving the slider to the right increases the density while moving it to the left decreases the density. Using the Macintosh Printer Driver 236
