The TC1617 developed by the Idealliance Print Properties Committee has been designated as the IT8.7/5 print characterization target. Developed over several years, as a successor to the IT8.7/4, the optimized IT8.7/5 includes critical K and CMY patches for gray balance reference in the P2P51 (columns 4 & 5 of the P2P51), while removing 29 duplicate patches to maintain the exact patch count and chart size utilized across many global print technologies and solutions. Since 2019, global adoption of the TC1617 has been widespread with these and other benefits for print workflows warranting the adoption by ANSI, CGATS, and ISO as the IT8.7/5 as part of ISO 12642-3.
