So many things happening in this video and we explain at the end. The basics are that we have created an ICC profile for separating an RGB image into four CMYK photogravure plates. To get there we had to do a lot of research & development and testing.
The process includes inking and printing test targets which we can measure to get data. We have all of the available cyan, magenta, yellow and black process inks. Each of them had to be tested in combination with each other in order to discover which combination had the largest color gamut (biggest range of printable colors.)
We write the software that we use to measure the data. We write the software that we use to linearize and calibrate the output. This software is proprietary to the studio, although we offer a commercial version to other printers.
During this process we also had to discover what ink additives would produce the least amount of offset during the printing of the four plates. We were trying to find a way to modify our inks so that the least amount would be pulled off of the paper by subsequent printings. We also tested chemicals we use in formulating inkjet inks. We left no stone unturned to arrive at highest color gamut.
During the printing we had to develop new methods for trimming the plates and registering them during the four plate printings.
Eventually, we arrived at the color gamut we were seeking. The registration method came together. The photogravure printed and matched the image on our calibrated display and the detail was extremely tight in the print.
We now have a way to commercially print full color images in photogravure.
