In textile applications, black is the most important color, and textile dyeing companies select black inks that enhance the companies’ competitiveness. This applies to inkjet inks, where achieving blacks comparable to that found in conventional printing is of great value. Konica Minolta’s Reactive dye ink TYPE – P, which was launched in 2011, has received high praise on the market for its superior color tone and high print density, but a higher density black ink has been requested and developed. In this report, we will introduce the technological development of two types of high-density black ink, together realizing the industry’s highest black densities.
