Color tab in the job parameters window 103

Parameter	Option	Description
	CMYK rendering	All printers, monitors, and scanners have a gamut or range
	intent	of colors that they can output (or view in the case of a
		scanner). If a color needs to be output and is outside the
		gamut of the output device, it must be mapped or
		approximated to some other color that exists within the
		gamut. Rendering intent compresses out-of-gamut colors
		into the color capability of the press you are using. When
		working with ICC profiles, it is important that you select the
		rendering intent that best preserves the important aspects
		of the image. Each rendering method specifies a CRD for
		color conversions.
		Provides the following options:
		● Auto—Select this option when your file includes
		different objects on the same page—for example, a
		presentation that includes JPEG pictures, text, and
		Excel graphs. A different rendering intent is
		automatically applied to each type of object (image, text,
		and graphic). If RGB images and CMYK graphic
		elements are on the same page, the RGB images will
		use the perceptual rendering intent, while the CMYK
		graphic elements will use the relative rendering intent.
		Note: Preserve pure CMY colors is not affected by this
		rendering intent option.
		● Relative—This is the default option for CMYK. This
		rendering intent maps some closely related colors in the
		input color space to the closest possible color in the
		output color space. This mapping reduces the number of
		colors in the image.
		● Absolute—Select this method for representing
		"signature" colors (colors that are strongly identified with
		a commercial product). Colors that fall inside the output
		color space are represented very accurately.
		● Saturation—Select this method for artwork and graphs
		in presentations. In many cases, this option can be used
		for mixed pages that contain both presentation graphics
		and photographs.
		Note: Select Saturation to achieve smoothness when
		you print RGB vector graphics (non image graphics).
		● Perceptual—This is the default option for RGB. Select
		this method when working with realistic images such as
		photographs, including scans and images from stock
		photography CDs. All or most colors in the original
		images are changed, but the relationship between the
		colors does not change.
