Adjusting the gray balance of reproductions on various substrates and achieving the desired visual appearance has been one of the most critical challenges and the primary source of the large volume of material waste and unproductive time.

G7® calibration reduces operation costs by reducing production cycles.

G7® is a specification and a calibration method that allows process control in any CMYK reproduction method and defines a grayscale's visual appearance. From a colour proof to the final printed sheet, it offers consistency, and it's relatively easy to implement.

G7® drive processing time and reduces waste

The efficiency of traditional lithography and digital printing depends on the work completed before the printing processes. Within the prepress stages is where the G7® methodology allows managing and optimizing the reproductions consistently.

The rapid make-readies, job changeovers without delay, and stable and consistent reproduction steps during production directly impact OEE.

G7® expands efficiencies and has a direct and positive effect on the printing process OEE.

Process standardization of make-readies and production are some of the benefits of the G7® methodology. This calibration methodology offers drastic reductions in make-ready times and applies to any printing equipment, substrates, or process inks.

The results obtained are consistent and produce a perfect gray balance and tonalities required to match the colour-proof and the colour rendering to satisfy the client.

G7® is at the center of process excellence

The G7® methodology is a vital part of the standardization of make-ready procedures, allowing consistency and predictable results. It also increases productivity, process stability, and the quality customer wants of the reproductions during production.

For technical evaluations and implementation of the G7® methodology or obtain the Master G7® international qualification, contact us directly at 416 697 8814. 

The G7® Master qualification indicates that the service provider has equipment and systems accurately calibrated to produce gray-balanced proof to finished products. That their printed products are consistent with G7® specifications, no matter the industry segment, equipment vintage, make, or reproduction technology.
