Setting which colors become black or white in black & white bitmaps

This procedure only applies to color images that will be using the Black

&White Bitmap output type. It allows you to create special effects, or to correct for originals on colored paper.

Images consist of pixels. In color images, each pixel has a varying amount of Red, Green, or Blue to create its specific color. You can determine whether the Red, Green, or Blue in each pixel turns to black or white in the final scanned image.
