GRACoL: General Requirements for Applications in Commercial Offset Lithography

In 1966 a graphics arts task force was formed by the Graphic Communications Association (GCA) to develop a document containing general guidelines and recommendations that could be used as a reference source across the industry for quality color printing, focused on sheetfed offset printing. The GRACoL Committee developed the printing guidelines that have since become de facto standards on many pressrooms. Today, GRACoL is an Idealliance Working Group, with the mission of improving communications and education in the graphic arts by maintaining the accuracy and the relevance of the GRACoL document in reporting the influence and impact of new technologies in the workflow of commercial offset lithography.

Idealliance ISO 12647-7, 3-Row Digital Control Wedge 2013
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 accuracy of every proof.

M1 Implementation Kit
Includes Idealliance GRACoL 2013 Adobe Color Settings Files for Use with Adobe CC/CS Applications. Idealliance 2013 Proof Verifier for use with GRACoL 2013, SWOP 2013 and as well as complete family of 7 G7 based datasets for different substrates and printing processes (ISO 15339/CGATS 21). Also includes 2013 Substrate Relative Calculator for use with GRACoL 2013, SWOP 2013 and as well as complete family of 7 G7 based datasets for different substrates and printing processes (ISO 15339/CGATS 21).

Proof Verifier for GRACoL 2013 / SWOP 2013
Idealliance 2013 Proof Verifier for use with GRACoL 2013, SWOP 2013 and as well as complete family of 7 G7 based datasets for different substrates and printing processes (ISO 15339/CGATS 21). This download contains a spreadsheet that allows for manual verification of Idealliance print conditions.

Substrate Relativity Calculator Kit
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 on how the substrates 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.

XCMYK Datasets and Profiles
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.
