In producing high quality inks for our digital printing solutions, several process steps must be taken. The first step involves sourcing the best raw dyes available. This is the ingredient that gives the inks it’s color. The better the quality of the raw dye, the more brilliant the color and the higher the quality of the end product.

Even first-class raw dyes contain minerals and other additives that can impact the quality of inks, which in turn determine the image quality of the printed fabric. Therefore, the next step in the production process is to purify the raw dyes and remove as much of unnecessary additives as possible. This process is done by means of a Dye Purification Unit – the DPU.

Each year, our production teams set out to control and, whenever possible, reduce the use of chemicals, waste and - specific for the DPU – demineralized water. The team, led by Bart Hanraets, created a hypothesis to optimize the use of the DPU in production circumstances. 

Production data of the DPU was available as of 2019, so proper analysis and comparisons could be made. After several tests and iteration cycles the team found an optimum. The results are impressive!
