It has a very big gamut, slightly bigger than ProPhoto RGB color space.Ĭalibrating all devices involved in the process chain (original, scanner/digital camera, monitor/printer) is required for an authentic color reproduction, because their actual color spaces differ device-specifically from the reference color spaces.Īn IT8 calibration is done with what are called IT8 targets, which are defined by the IT8 standards. This is an IT8 color target made in EGM Laboratories in Barcelona, Spain. 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. 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. IT8.7/3 - 1993 (R2003) Graphic technology - Input data for characterization of 4-color process printing 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. It is intended to address the color photographic paper products that are generally used for input to the preparatory process for printing and publishing.
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. IT8.7/2 - 1993 (R2003) Graphic technology - Color reflection target for input scanner calibration 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. It is intended to address the color transparency products that are generally used for input to the preparatory process for printing and publishing. IT8.7/1 - 1993 (R2003) - Graphic technology - Color transmission target for input scanner calibration The information will typically consist of numerical control information used in the manufacture of dies. This standard establishes a data exchange format to enable transfer of numerical control information between diecutting systems and electronic prepress systems. The following is a list of the IT8 standards, according to the NPES Standards Blue Book: IT8.6 - 2002 - Graphic technology - Prepress digital data exchange - Diecutting data (DDES3) 1.4 IT8.7/3 - 1993 (R2003) Graphic technology - Input data for characterization of 4-color process printing.1.3 IT8.7/2 - 1993 (R2003) Graphic technology - Color reflection target for input scanner calibration.1.2 IT8.7/1 - 1993 (R2003) - Graphic technology - Color transmission target for input scanner calibration.
