Values set upon installation of software.
Density
Refers to the deepness of a color in an image.
Device error
An error which requires troubleshooting by a service engineer.
Dither
The process by which a group of dots is arranged to reproduce the density of grayscale. Grayscale density is reproduced by
configuring preset dot patterns. This method requires less memory compared to multilevel gray.
dpi (dots per inch)
A measurement of resolution which is used for scanners and printers. Higher dpi indicates better resolution.
Driver
A program specifically designed for operating systems, which enables interaction with a hardware device.
Dropout color
A function which removes a specified color from a scanned image.
E
Edge Extract
A function which traces the boundaries between black and white areas, and extracts them as outlines.
Emphasis
A function which decreases the density of bright colors (except for white) around black areas. Increasing the value for this
function removes dotted image noise and also produces "softened" images.
