Dear contributors The initial question in this thread was whether the onboard tools from Adobe can achieve qualitatively comparable results as the third-party software from callas. Many responses have been received that delve deep into the topic. Thanks for that!
Unfortunately for me, at a certain point I reach the limits of my knowledge when it comes to the physics of color management. Also due to lack of time and lack of influence on the entire workflow, it is not in my hands to change basic processes (such as the exclusive use of RGB images). Therefore, I can unfortunately not implement some well-intentioned advice. What really helps me here is a "brave", concrete answer as to whether my settings are objectionable in this form when exporting to InDesign, or whether they are correct (see attached image in my first post). They look logically correct to me, but unfortunately sometimes you don't see everything yourself. So I take from rob days' first answer that they are probably correct. It's good. Also, his answer confirms my suspicion that you don't actually need any additional software. The only thing I miss here is the (automatic) identifier "FOGRA40". I don't know how important that is. The printer's specifications require it. It can be entered manually in the export settings under "Identification of the initial condition". This has no effect, it is only displayed. The only reason I haven't marked the answer as correct so far is that I'm still unsure overall. As described, I get different results with the two methods. See also my 4 attachments with the color samples. That led me to my next question: about the settings in callas. These are numerous and require a lot of expertise. But I don't want to go into that any further now. As I noticed, only a few people in this forum have experience with the pdfToolbox. Nevertheless, I have attached a screenshot of the profile I created in callas.
Thanks again to everyone who contributed to this. regards
