All ink batches manufactured by InkTec are managed by objective quality control. We ensure stable quality of the inks by evaluating the passing or failure of each batch by our own criteria. Furthermore, the printing properties, which are the critical determining factors during the development of new inks, are also tested to check the ink performance.

The physical properties are also measured by a precise analytical system and are recorded on our COI (Certification of Inspection) which is available for public viewing. By testing the manufactured inks for the conditions that were already checked during the development, we ensure that our quality control system is complete and thorough.
