G7 Color Management for Metal Can Printing Industries

Huayuan Packaging obtains world’s first metal printing G7 certification utilizing CGS ORIS color management

In September 2021, IDEAlliance GBA (International Digital Enterprise Alliance Greater Bay Area Branch) notified Huayuan Packaging (Qingyuan) Co., Ltd. That it became the world’s first (and so far, the ONLY) metal can printing company who has received a G7 certification:

As the leading company in the metal printing field, Huayuan Holdings was established in 1998 as a comprehensive packaging solutions provider, integrating solutions planning, packaging design and product manufacturing as its core business. At present, there are more than 20 production facilities throughout China – 5 lithographic plants, 10 metal can manufacturing plants, 2 metal cover plants, plus 8 plastic packaging production plants. 

In 2020, Huayuan Holdings invested and established Huayuan Packaging (Qingyuan) Co., Ltd. in Qingyuan, Guangdong. This facility attaches great importance to the application of innovative metal can manufacturing technologies and processes. After extensive research, they partnered with CGS ORIS and its regional partner Shenzhen Surewell Technology, to implement the full suite of color management solutions from CGS ORIS.

In August 2021, Huayuan Packaging successfully implemented expanded color gamut printing on a 7-color metal printing press as well as a digital inkjet metal packaging proofing system. CGS ORIS color management solutions and the professional technical service team of Suwei Technology helped Huayuan execute this project to success; Using CGS ORIS’ FLEX PACK packaging proofing system with an Epson eco-solvent printer, color matching of over 90% of brand colors printed on Huayuan’s presses were achieved. Furthermore, CGS ORIS’ X GAMUT was used to successfully implement expanded color gamut (ECG) printing innovation on Huayuan’s 7-color metal printing press, and helps Huayuan to flexibly manage its short run, multi-spot-color printing.

In order to meet the stringent requirements of Huayuan Packaging’s high-end brand customers, and the demanding challenges of the international printing standards facing metal printing companies, a decision was made to implement G7 certification together with the multi-color separation project. 

Because of its difference from general offset printing processes on paper, advanced standardization and managed quality control for multi-color metal printing presses is quite rare in the field of metal printing; after the initial metal printing is completed, an in-line UV varnish is applied before a curing process of as high as 320 degrees Fahrenheit – as one could imagine, this is a difficult process to manage.

Even so, the powerful CGS ORIS solutions X GAMUT, FLEX PACK, CERTIFIED and CXF TOOLBOX, plus diligent group efforts of CGS ORIS, Surewell Technology and the entire team at Huayuan Packaging accomplished its goals exceptionally. The final measured data from Huayuan’s CMYKRGB metal printing process achieved the G7 gray balance standard, as well as meet the tighter G7 Target level compliance.

The G7 certification of Huayuan Packaging in the field of metal printing is an unprecedented achievement in the metal printing industry. It strongly illustrates that the G7 color correction method can be applied to not only any CMYK four-color process printing arena, but also be carried out in the multicolor, expanded color gamut metal printing field.

This accomplishment fills a much needed gap within the metal printing industry globally, as well as in Greater China. This certification creates a benchmark reference for metal printing companies by providing empirical, measured data, and at the same time sets an example and model for the global metal printing industry of what can accomplished.

Mr. Zhang Xinyi, General Manager of Huayuan Holdings, said, “Science and technology are the primary productive forces. The concept of standardization is extended to the field of metal printing. G7 certification not only promotes Huayuan Packaging as a leader in the industry, but we also clearly see the improvement of product quality through visual color results. In the future, we will expand these processes to the other branches of our companies to promote G7 color management technology. Let Huayuan’s color become a business standard for the metal printing industry, and Huayuan’s quality become a standard for the global metal industry to follow.”
