Quality assurance

Providing products with competitive quality, costs, and delivery times

At Sogo Printing, we believe that maintaining and improving the quality of our products is of the greatest importance. To this end, we have formulated permanent policies on product quality, and established ISO 9001-compliant quality management systems at all our business sites. Since required levels of quality requirement have been increasing every year, going forward we intend to pursue further improvements in both the level and efficiency of our management systems.

ISO 9001 Quality Management System

Printed materials range widely from packaging and display materials to advertising and promotional materials. Our main products—pharmaceuticals and cosmetics packaging, labels, and package inserts—require particularly high quality and reliability. All our business sites have acquired ISO 9001 certification, and we are continuously working to improve and enhance quality by implementing our quality management system based on that standard.
