G7+ Calibration and Qualification

Professional G7+ Print Standardization Services

Prestia Consulting offers G7+ calibration of print systems through Alder Color expertise. G7+ Qualification submissions to Printing United Alliance are handled for both initial qualifications and bi-annual re-qualifications.

Even for operations not seeking formal Qualification, G7+ is a method to calibrate a printing system for Universal Consistency, Enhanced Gray Balance, Smoother Tonality, and Substrate-Specific Control (SCCA). G7 Colorspace Compliance ensures that printed colors match not just in neutral tones and highlight-to-midtone colors, but also in saturated colors.

G7+ implementation differs from legacy G7 in that it positions qualified shops to match the Universal Characterization Dataset (UCD), which may replace other standards including GRACoL, SWOP, and some Fogra standards in the future.

G7+ Expert Certified

Lou Prestia is a G7+ Expert and is also certified to perform G7+ calibrations and submissions. In some cases he may deliver these services on behalf of Alder Color. He has completed over 50 G7 certifications.

Key Benefits

Who Needs G7+ Services?

G7+ calibration and qualification is essential for print providers seeking to meet industry standards and expand business opportunities:

Process and Methodology

The G7+ qualification process follows a comprehensive methodology to ensure consistent, repeatable results:

Step-by-Step Process

1. System Inspection: Inspect and qualify printing system for consistency and base calibration.

2. Test Printing: Print test forms containing targets required for G7 neutral density curve calculation and other press performance criteria using ISO 12647-x targets for the specific print process.

3. Measurement & Analysis: Measure G7+ targets from multiple samples to generate neutral print density curves.

4. Curve Loading: Load curves on prepress equipment for qualification print run.

5. Qualification Submission: Submit samples to Printing United Alliance for G7+ Qualification.

6. Color Profiling: Generate color profiling targets so that the press can be confirmed for G7+ Colorspace conformance and matched to other print systems or substrates.

We train everyone involved in this process about what each step is, how to perform it, and how it contributes to a successful G7+ implementation. We also train additional personnel such as sales and marketing teams on the technical basics of G7+ and the value it adds, so they can communicate it effectively to customers.
