Idealliance, known for creating legendary print standards and specifications such as GRACoL®, SWOP®, and G7® has released an Expanded Color Gamut (ECG) characterization chart for use in characterizing and calibrating multicolor print processes. The Expanded Color Gamut (ECG) Characterization Chart was created by a subcommittee within the Idealliance Print Properties and Colorimetric Council as a part of the Idealliance Global ECG project. The Idealliance Global ECG is designed to make 7 color process printing as predictable and normal as current CMYK printing specifications such as GRACoL and SWOP. The characterization chart will complement a comprehensive Expanded Color Gamut (ECG) Project Kit which contains guidelines, proofing control strips, and other tools for print users.

The Idealliance ISO 12647-7 Control Wedge 2013 has 3 rows and 84 patches vs. the 2-row 54 patches in the original 2006 version. The wedge is intended primarily as a control device for prepress proofs but may also be used to control production printers or presses. The target must pass through exactly the same imaging process as a live image, including RIP curves, color management, screening, etc. The target MUST be included on all proofs submitted for Idealliance Proofing System certification. Values measured from the target will be used as part of the Idealliance proofing system certification process. The target SHOULD be included on all production proofs and measured to confirm the accuracy of every proof. The previous version, Idealliance ISO 12647-7: 2009 Digital Control strip, can be downloaded here.

The IT8.7/5 (TC1617x) is a new CMYK printer characterization target combining the unique patch values in the standard IT8.7/4 target with all the patch values in columns 4 and 5 of the P2P51 target. The TC1617x maintains the same patch count as the IT8.7/4 (1,617 – hence the name) by removing 29 duplicate patches from the IT8.7/4 and replacing them with the 29 patches in columns 4 and 5 of the P2P51 that were absent in the IT8.7/4.
These are the IT8.7/5 / TC1617x datasets for Characterized Reference Printing Conditions 1-7.
The first of its kind for this segment of the industry, the Idealliance Large Format – Industrial – Textile Printing Control Wedge was created by the Idealliance Print Properties & Colorimetric Council in order to support the wide format, industrial and textile print segments of the industry. The control wedge is designed to help digital print users on non-traditional substrates exceptionally control their print processes. The control wedge comes in a variety of configurations and can be read with devices that have larger apertures and work especially well in situations with uneven surfaces, textiles, and wide format printing.
The Idealliance Print Properties and Colorimetric Council have created a kit detailing steps which can improve the proof to press match by using SCCA (Substate Corrected Colorimetric Aims) adjusted versions of CRPC (Characterized Reference Print Conditions) profiles, and/or by creating custom versions of CRPC and substrate profiles using custom daylight color temperatures. The kit contains extensive documentation on how to improve the press to proof match. In addition, the Idealliance Print Properties Council has created SCCA adjusted versions of GRACoL® 2013 with higher levels of OBAs.

PrintWide is a new, extremely large-gamut CMYK dataset designed to encompass the gamut of virtually all inks or colorants in all known color printing systems and serves as a CMYK translation space and G7 aligned saturation booster. Although the dataset has only four channels (CMYK), its gamut includes the effect of typical “extended-gamut” inks such as OGV (Orange, Green and Violet) or RGB (Red Green and Blue) often used in ink-jet, flexo or offset printing.

*Updated 2019* The Substrate Relativity Calculator allows advanced users the ability to recalculate industry-standard or custom characterization data sets based on the CIELAB values of a given substrate. The procedure utilizes the tristimulus correction methodology defined in ISO 13655 Annex A for correcting measurements based on two backing materials. Once the data is modified relative to the new CIELAB values, the user is provided an idea of how the substrate’s color will affect the final printed result. The recalculated data can be used to generate profiles for more accurate proofing/converting, and the reported CMYK, RGB, and Gray patches can be used for new process control aims when on press with the new substrate. A video introduction & walk-thru is also available to accompany the SCCA calculator, click here.
XCMYK is a new color space representing expanded gamut printing that can be achieved on offset and digital devices. The XCMYK dataset and profiles can reproduce a larger gamut than that of GRACoL®, the industry’s current standard for print quality. Profiles can be used on traditional four-color presses as well as on a variety of digital devices to produce a color space larger than current traditional printing.
