For the commercial printers out there - linearization / Profiling
I am in a bit of a crossroads on a project that has been more than a year in the works. Not sure how to post without getting into specific details. Every single challenge that has come with this project, we have been able to pass. From product flow to pilot site integration. All except this one thing....

I have a test file, photographic image, that will be the death of me. I can build linearization and ICC with peak dE less than 2 using any compatible low gain photographic media. All day long I can build fantastic profiles with good media and this image prints excellent. I can stay less than dE 4 with most inkjet coated media and some compatible offset (with heaters) using this ink.

The moment I build a profile for 24# plain paper, (yes, I know.. but it is the task in front of me) no matter what dE goes sky high. This is to be expected. But the print result is awful. Clearly can be improved. In fact, if I curve and level the image manually in Photoshop, the print result looks so much better using the same Lin and ICC. Clearly I am missing something. I'm just at a loss. The image should not look this washed out and flat (proven with the Photoshop test and same RIP settings for plain). I just don't know where to go from here. They say crap in, crap out when printing but this crap doesn't have to be so bad

Any advice, places to look would be fantastic

Latest TAC 180% with acceptable artifacts. Lower obviously reduces gamut, higher overloads the paper. The media should really set 160% max and arguably 120% for minimum artifacts. With such bad luck on this image, I suspect its the black weight settings? Latest profile I kept K max 100% to allow best text and solids (which is a requirement), maybe this is washing out color weight.

I'm sorry, but I have literally no idea what you're talking about.

WARNING I'm pretending to know much more than I really do; however, you appear to be in the industrial/commercial of mass printing, which is why your tech terminology is incomprehensible to us.

I have always known that laser printing colour or otherwise gives superior results; therefore, why not use laser?

The printing machine has to be re-calibrated to accept 24# plain paper which I think maybe software related.

What I've just said has not come out my mouth!!!

However, as you have been a forum member for 14 years it would be interesting to know the technical specifics of what is involved.

PS if you want to know how to spin your car wheels using only two frames, then I'm yer man.
