							Color Reproduction for the HP Large Format Color Copier products family. 51/52 
It distinguishes light from dark areas. 
LUT file 
A Look-Up Table (LUT) file. It correlates n-dimensional 
entries with m-dimensional outputs. In this instance, it 
correlates a 1-dimensional entry (the lightness) with a 3-
dimensional output (the corresponding Red, Green and 
Blue values). 
Media 
The physical material on which an image is formed 
(printed). 
Media profile 
A description of the media and printing system’s behavior, 
including which colors can be reproduced on the media 
and how to reproduce them. 
Non-reproducible color 
A color that cannot be reproduced by the system either 
because the color is not correctly “seen” by the scanner 
(which detects it as a different color) or because it cannot 
be printed by the printer (ink/media limitation). 
Original 
The printed media that has the original image formed on 
it. 
Printhead alignment 
The process of setting printer parameters to minimize ink 
drops placement errors when printing. It is performed 
automatically each time a printhead is replaced or may be 
started manually. 
Printing 
The transfer of ink onto paper or other media to reproduce 
text and images. 
Saturation 
The purity of a color’s hue, moving from gray to the pure 
color. A high saturation corresponds to a strong color. 
Conceptually equivalent to a scale from pale/weak (low 
saturation) to pure/strong (high saturation). 
Scan resolution 
The resolution at which the scanner digitizes the original 
image. It is reported in dpi (dots per inch). 
Scanning 
The digitizing of the original image. 
Sharpen 
To enhance the contrast at the edges of light and dark 
areas, with the effect of making an image appear better 
defined, more in focus. 
Stitching 
The process of aligning the two cameras of the scanner so 
that when the two images are composed the differences 
along the overlapping area are minimized. It is executed 
every time the operator performs scanner maintenance.  
Touch screen 
The interface between the user, the scanner and the 
printer. 
Type of original 
A template that describes the characteristics of an original 
image and the color management and image 
enhancements it requires.
