For example, increasing the sharpness could make text appear crisper, but decreasing it could make photos appear smoother. ● Darkness: Increase or decrease the amount of white and black used in colors in scanned images. ● Contrast: Increase or decrease the difference between the lightest and the darkest color on the page. ● Background Cleanup: Remove faint colors from the background of scanned images. For example, if the original document is printed on colored paper, use this feature to lighten the background without affecting the darkness of the image. ● Automatic Tone: Available for Flow printers only.
