Adjusting the Finished Result in the Preview Window

At the preview window, you can adjust the brightness, contrast, and gamma correction. An image with clearly

dened light and dark areas produces attractive printed results.

Brightness

This adjusts the overall brightness.

Making the value too large can destroy

the balance, so it may be a good idea

to adjust it to the absolute minimum

necessary.

Contrast

This mainly adjusts highlights (the bright-

est areas) and shadows (the darkest ar-

eas). Using this can be eective when you

want to achieve a sense of tension with a

good balance of light and dark.

Gamma

This mainly adjusts the brightness

of tones of intermediate brightness

between bright and dark areas. Using

it is effective in adjusting the overall

brightness.

The dark and bright areas are printed as

shown in the gure.

Dark-color areas are not struck, and light-

color areas are struck forcefully.

Also, the printing results before and after

adjustment are as shown below.
