G7® Master Facility Qualification


Idealliance G7 Master Facility Qualification is a three-level compliance program that is granted to physical facilities such as printing companies or other graphic solutions providers, creative and premedia proofers, conducted by Idealliance certified G7 Experts and G7 Professionals. G7 Master status indicates the facility has calibrated certain equipment and systems to G7 gray balance and neutral tone curves and is capable of delivering G7 proofs and print products.

G7® is Idealliance’s global industry-leading set of specifications for achieving visual similarity across all print processes.

Globally Recognized Qualification Benefits

For business owners, the benefits of being a G7 Master Facility are simple. Your print products are consistent, which helps maintain the integrity of your customers’ brand—and turns these customers into repeat customers. Your customer base will increase due to print buyers actively seeking out suppliers who are G7 certified. And lastly, your costs will go down because of reduced paper waste and ink consumption.

How To Become a G7 Master Qualified Facility

Have an Idealliance G7 Certified Expert visit your print facility

You can hire G7 expert consultant by visiting 

He/She will be conduct and review your calibration data

An online application and print verification will be submitted to an independent 3rd party analysis lab.


Once approved, your G7 Master Facility Qualification will be granted.

Two Options for Getting G7 Master Facility Qualified

An Idealliance certified G7 Expert is required to qualify print facilities for the first time. A G7 Expert must be onsite to conduct and review calibration data, then submits an online application to Idealliance for 3rd party verification. Final G7 Master Facility Qualification is granted by Idealliance.

G7 Master Facility Qualification Compliance Levels

Qualification is granted according to three distinct compliance levels: Gray, Targeted, and Colorspace.

What G7 Compliance Level is Right for Your Business?

Gray Balance Tonality Shared Neutal Appearance Overprint Entire Colorspace
Close match in neutral grays but may exhibit differences in colored areas
Close match in grays but may have differences in some colors
Close match across a G7-based color space

This is the fundamental level of G7. Regardless of printing technology, if we can ensure that a printer or press prints the neutral tone ramp well, then all other colors will tend to fall into line more easily.

Grayscale is the level that we are used to seeing. A target print is printed on a stable printing system and measurements of that target are used to correct the ink curves to bring the printing system into alignment with the G7 ideal neutral density curve.

Aligning the printing of various printing methods in a plant to this same neutral aim point is a tremendous step forward in getting these disparate printers to match. While achieving this G7 level will naturally help all the colors to be consistent, the only thing that is required at this level is for the K and CMY neutrals to be aligned to the G7 tone curve and the CMY neutrals gray balanced. 

This is the intermediate level of G7 and G7 Targeted is achieved when G7 Grayscale is achieved, plus the solid ink measurements for primaries and secondaries (CMY and RGB) and substrate color are also within spec to one of the G7-based TARGETED color spaces.

This can be achieved according to the absolute white point or using substrate-relative condition. G7 Targeted compliance is not limited to only the reference print conditions in ISO 12647-2 or in ISO PAS 15339, any G7-calibrated dataset can be used as G7 reference print condition.

Those who want, can use their own color reference in place of the standard CRPC’s, but their files must be verified as being compliant with G7 Grayscale.

G7 Targeted achievement lets customers know that not only can a facility hit G7 Grayscale, but they can also achieve a higher level of compliance and their strongest colors can hit, for example, the specific LAB values for GRACoL 2013. 

This is the highest level of G7 compliance and the most stringent. G7 Colorspace includes all the requirements of the G7 Targeted level (and therefore the G7 Grayscale level) and adds the matching to an entire Reference Print Condition. This level demonstrates that you are maintaining extremely tight tolerances throughout the whole color space. An entire IT8.7/4 target is compared against the targeted color space and the average of all the 1617 patches needs to be with a narrow range of tolerances. This assures that the printing system can consistently reproduce the entire color space and not just the primaries and secondaries (CMY and RGB).

G7 Colorspace can also be relative to either the absolute white point or the substrate-relative aim values. 

G7 Colorspace level is also further divided into two separate purposes, Printing or Proofing. There are slightly more stringent requirements (tolerances) for proofing.
