As food packaging safety standards continue to evolve, HAURTYI Paper Bag has adopted mineral oil-free inks compliant with EU and French regulations on MOSH/MOAH, providing a safer and more sustainable printing solution for paper packaging.

One challenge we encountered during implementation was that most commercially available color guides are printed with conventional mineral oil-based inks, making them unsuitable as reliable color references for mineral oil-free printing.

To achieve consistent color reproduction, we invested considerable effort in sourcing a color management solution aligned with international standards. We ultimately adopted the ISO CMYK Color Guide, developed by National Taiwan University of Arts in accordance with ISO 15339. Printed with mineral oil-free inks and available for both coated and uncoated substrates, it provides standardized color references for consistent color communication and process control.

As the first edition had long been out of print, we were fortunate to obtain a copy through the generous support of Tung Ming Printing Ink and Jerry of T-Lab Color. This valuable resource further strengthens HAURTYIs color management capability for mineral oil-free printing.

We sincerely thank General Manager Cho Hsun-Chun, together with the professional teams at Tung Ming Printing Ink and T-Lab Color, for their expertise and support.

Customers may never notice the difference in the inks we use, or the effort invested behind every color standard.

But we believe true brand value lies in perfecting the details customers never see—and consistently exceeding expectations.

At HAURTYI Paper Bag, every paper bag represents more than packaging. It reflects our commitment to quality, food safety, color consistency, and sustainability.
