The document discusses color management in printing. It defines color management as using ICC profiles to accurately portray colors across different devices and color spaces. It explains that ICC profiles describe how a device or color space represents colors, allowing colors to be converted between devices and spaces. The document provides examples of common ICC profiles used in printing and outlines important aspects of color management like solid ink density values, adjusting tonal value increase curves, and standards for contract proofs.

 PDF Export from ID
 In this field it is very important to
select the proper colour conversion
settings yourself:
– please check with your output
provider which ICC profile is
appropriate, or select the ICC
profile that was used for converting
images to CMYK in PhotoShop or
InDesign.
– For WebCmykHiRes _1v4, we
recommend you to use the
ISOcoated_v2_300_eci ICC profile
 Colours in your document will
change if:
– objects in RGB colour space with
or without ICC profiles are used in
the document
– CMYK objects with different ICC
profiles are placed in the document

8. ICC profiles
 In color management, an ICC profile is a set of data that characterizes a
color input or output device, or a color space, according to standards
promulgated by the International Color Consortium (ICC).
 Profiles describe the color attributes of a particular device or viewing
requirement by defining a mapping between the device source or target
color space and a profile connection space (PCS). This PCS is either CIELAB
(L*a*b*) or CIEXYZ. Mappings may be specified using tables, to which
interpolation is applied, or through a series of parameters for
transformations.

9. ICC profiles
 Every device that captures or displays color can be profiled. Some
manufacturers provide profiles for their products, and there are several
products that allow an end user to generate his or her own color profiles,
typically through the use of a tristimulus colorimeter or preferably a
spectrophotometer.
