Consistency is key. In the packaging industry, the GMI standard is a necessary certification to control viscosity in print quality. In this article, we will learn the role and meaning of GMI standards in the printing and packaging industry.
What is the GMI standard?
GMI (abbreviation for Graphic Measures International) is the world’s leading measurement organization for the quality control process of packaging printing. In other words, GMI is a standardized system that brands use to evaluate the quality and consistency of printed products.
In printing and manufacturing export packaging, certifications such as GMI, ISO 12647, GATF, Gracol, and PSO are essential for packaging companies. In particular, GMI is like a passport to participate in the global supply chain, especially for customers in the US market, such as Walgreens, Target, Lowe’s, Home Depot, CVS, and Mondelez.
In addition, GMI is used as a common standard to evaluate print quality and uses GMI to resolve print quality disputes. The printing manufacturer must follow a rigorous system to achieve this certification. Currently, about 1,000 companies in the world are conducting GMI, of which about 300 are located in China. This number in Vietnam is very modest; most are FDI companies.
GMI certification assesses five key components: process and documentation control, equipment maintenance, training procedures, operator competence, and equipment performance.
The importance of GMI certification for packaged products
GMI helps control variables and ensure brand integrity through printer certification, in-process sample measurement, and in-store packaging assessment.
The GMI process is based on ISO 12647 – one of the best standards in the printing industry. GMI takes these standards and applies a scoring system to them. Brands can choose the metrics they want to track, and GMI sets the parameters for each. During the packaging printing process, GMI will check the printed samples and evaluate the score, and the score will be between 0 and 3, specifically:
- 0 is ideal; there are no flaws.
- 1 and 2 indicate minor flaws.
- 3 shows a significant error with the entire print job.
Printing to GMI standards is like playing gold; the fewer points, the better. The higher the score, the more disadvantageous, sometimes having to start from the beginning.

How to maintain GMI certification?
After a printer achieves GMI certification, the journey is still ongoing; a lot of work must be done to maintain print quality and standards. They need to be responsible, ensuring continuity and consistency in each printed product before it is delivered to customers. In addition, there are three levels of GMI certification for printers:
- Platinum: High-performance printing supplier, continuity score not less than 90%
- Gold & Silver: Good print supplier condition, continuous score in the range of 80% – 89%.
- Bronze: Printer under review, under 79% GMI typically adds about 15% to the cost of any print job.
The brand will pay this cost to GMI to track and inspect its printed materials. GMI certificate is becoming popular because it helps printing units create trust for domestic and export partners and customers.
