IT8
From Wikipedia, the free encyclopedia
IT8 is a set of American National Standards Institute (ANSI) standards for color communications and control specifications. Formerly governed by the IT8 Committee, IT8 activities were merged with those of the Committee for Graphics Arts Technologies Standards (CGATS) in 1994.
[edit] Standards List
The following is a list of the IT8 standards, according to the NPES Standards Blue Book:
[edit] IT8.6 - 2002 - Graphic technology - Prepress digital data exchange - Diecutting data (DDES3)
This standard establishes a data exchange format to enable transfer of numerical control information between diecutting systems and electronic prepress systems. The information will typically consist of numerical control information used in the manufacture of dies. 37 pp.
[edit] IT8.7/1 - 1993 (R2003) - Graphic technology - Color transmission target for input scanner calibration
This standard defines an input test target that will allow any color input scanner to be calibrated with any film dye set used to create the target. It is intended to address the color transparency products that are generally used for input to the preparatory process for printing and publishing. This standard defines the layout and colorimetric values of a target that can be manufactured on any positive color transparency film and that is intended for use in the calibration of a photographic film/scanner combination. 32 pp.
[edit] IT8.7/2 - 1993 (R2003) Graphic technology - Color reflection target for input scanner calibration
This standard defines an input test target that will allow any color input scanner to be calibrated with any film dye set used to create the target. It is intended to address the color photographic paper products that are generally used for input to the preparatory process for printing and publishing. It defines the layout and colorimetric values of the target that can be manufactured on any color photographic paper and is intended for use in the calibration of a photographic paper/scanner combination. 29 pp.
[edit] IT8.7/3 - 1993 (R2003) Graphic technology - Input data for characterization of 4-color process printing
The purpose of this standard is to specify an input data file, a measurement procedure and an output data format to characterize any four-color printing process. The output data (characterization) file should be transferred with any four-color (cyan, magenta, yellow and black) halftone image files to enable a color transformation to be undertaken when required. 29 pp.
