It all sounds interesting although you lost me with the different printing methods. As a boy my father use to take me around the news paper where he worked back when it was linotype machines and hot metal. I remember that when the presses were running they could be felt throughout the building and up close they were monsters as were the rolls of paper (elephants I think).
I'm with you on Adobe. I tried to help my daughter with Illustrator (industry standard ha) and found that while it was loaded with features the actual implementation of those features was often quite crude, for instance fine positioning of a control point on a curve was very hard work whereas in Affinity Designer it was simple. However, I should stress that I don't know what I'm talking about but think it is a pity that Universities perpetuate the myth that its Adobe or nothing. I had a quick peek at Esko website - looks good but I did not find any prices, so will mark it down as reassuringly expensive.
. Well not that my code will ever be competition but my delving inside raw files is due to me refusing to rent Lightroom from them. Ever since "upgrading" to Catalina my 16/32 bit version of Lightroom has stopped working ; neat trick by Adobe the app is 32 bit but the installer and licensing app is 16 bit. Anyway I now using a collection of Apps to manage my image collection but I still needed something better than the Finder to move images from the memory card to the hard drive. The files have to be renamed and stored in sub folders according to capture date and I want to ensure images are not imported twice.but I'd really LOVE for Adobe to have some real competition again!
I'm just starting my third redesign and its partly your fault

best wishes
