Hello, It’s been more than five years since I visited the forum last, with a lot of questions concerning tritone printing. After my book “Stockholm/Brussels” came out, I was quite satisfied with the state of affairs in printing. However, a new book is in preparation, in color this time. I recently heard about a new printing standard for my favorite Lumisilk coated sheet paper, called Fogra 51. Alas, unable to choose it from among the alternatives provided by Adobe in the Photoshop menu "Color settings”. Could someone more experienced walk me through how to install this new standard in all my versions of Photoshop, CS5, CS 2017 and CS 2021? Cheers Emil emsvision.com
