G7 standards in printing and their importance to the packaging industry
Facing the challenge of color differences in packaging from proof to press, between different printing presses, Hoang Vuong Paper Packaging has applied and achieved the G7 standard – a globally reputable color control method.
This certification contributes to demonstrating the capability and innovation in Hoang Vuong’s production, ensuring stable and consistent print quality for large quantities of finished packaging. We hope this article is helpful for you.
The G7 standard is an internationally recognized system designed to calibrate and control the printing process.
Introduction to G7 – Calibration and Control Method for the Printing Process
The G7 method is a process used to reproduce color visually accurately by emphasizing the alignment of gray balance between different printing processes. G7 stands for Gray plus seven colors – “7 colors of ISO CMYK and RGB.” This method is used in various printing applications, such as offset lithography, because it utilizes a one-dimensional neutral print density curve (NPDC) to match neutral tones between two G7-calibrated printing systems.
Using the G7 method to calibrate a print job is a manual process and is not device-dependent. G7 can be applied to any printing device that allows operation with raster image processing or computer-to-plate information, indicating how the digital signals from an image printed with ink are.

G7 Standard in Packaging Printing
The G7 certification is awarded to packaging manufacturers with printing facilities that achieve quality and consistency in imaging across various processes and printing devices. This certification is issued by IDEAlliance, a global association of graphic communication experts, based on the G7 method—a set of technical specifications for calibrating printers and proofing systems.
The G7 certification must be renewed annually, and it requires the support of a G7 Expert to guide the print provider through the G7 assessment process. G7 Experts and program trainers must pass a comprehensive G7 exam, and their certification is renewed every two years.
As a significant breakthrough in printing technology and innovation, the G7 standard brings maximum quality and provides nearly perfect color-matching capability. Finished products produced by a G7-certified company will adhere to a rationalized process, allowing for shorter processing times while maintaining strict quality control throughout the entire process.

G7 is an internationally recognized system designed to calibrate and verify printing systems, ultimately raising the standards for color accuracy. G7 has become an industry leader in meeting requirements, ensuring consistency and accuracy across all prints. It achieves this by selectively adjusting the CMYK levels on printing devices to match colors. G7 calibration can be implemented on nearly any printing press or imaging device, as long as it is done to the G7 standard. In simple terms, G7 makes the process of proofing and final printing more standardized, resulting in higher quality.
The role of the G7 printing standard in the packaging industry
Packaging samples that meet the G7 printing standard are used for both proofing and final printing systems. G7 uses “gray balance” data to achieve a gray balance result conforming to the ISO 10128:2009 neutral print density standard.
The G7 standard in the packaging industry has several advantages:
- It helps control grayscale tones across increasing levels from 0% to 100%.
- Adjusts curves for the three CMY components and black K color.
- Ensures consistent prints during proofing and maintains quality and color consistency when printing on actual products.
- Demonstrates the professionalism and expertise of the manufacturer and printer when achieving the G7 standard.
- Commitment to consistency in large-scale printing to attract customers to choose printing services at the company.
The G7 method is applicable to various packaging printing technologies such as offset, flexographic, digital printing, silk screen printing, etc. It is used for all types of inks and printing materials, including non-ISO standard materials.
G7 uses “tone value” data to achieve a color balance that conforms to the ISO 10128:2009 neutral print density standard.
Why is it necessary to control print quality on packaging?
Controlling print quality on packaging is a crucial step in the packaging production process. Packaging plays a vital role in protecting the product, ensuring its safe and convenient transportation and storage. If the print quality on packaging is not well-controlled, it can lead to issues such as loss of goods, reporting errors, and even customer loss.
