DocuSP color management • Black Overprint compensates for the band of white that may appear when black text is printed directly on top of a color. NOTE: Black Overprint produces sometimes-unexpected results using iGen3, due to its unique technology. Therefore, you should avoid using this feature on the iGen3. • Anti-aliasing reduces the jagged appearance of lines and curves in text and line art. Expert color Expert color contains a set of tools for the skilled user to optimize color quality. • The Source color tab provides access to a list of source color profiles. This selection is used to translate undefined data in the incoming job. DocuSP honors embedded source profiles. • The Output color tab provides access to a set of tools that are applied as part of the color transformation from the device independent space to the print engine CMYK space. - Halftones are screen patterns achieved by printing dots or lines in a specific pattern. The distance between the dots is fixed. Dot size varies in accordance to the strength of the color. The darker the color the larger the dot. Halftones supported on the iGen3 include 150 dot, 175 dot, 200 dot and stochastic screens. The DC 20xx/60xx series supports 150 dot, 200 dot, 200 line, 300 line, and 600 line screens. Stochastic halftones randomly apply screens when the difference in tone varies by different concentrations of dots and by dot sizes. - Image Resample Interpolation is a method to achieve maximum image quality. Interpolation estimates a value of function between two known values and attempts to produce a smooth transition between adjacent samples rather than replicating pixels which would result in "blocky" images. The supported interpolation methods include: Nearest neighbor Bi-linear Smart Color Management Guide 2-11
