OK, you seem to be on the right track at this point.
For what it is worth, the MK does not play well with digital negatives. For starters, it has way more UV blocking strength than any of the other inks in the K3 set, which can cause a grainy look, and it does not dry hard on OHP.

I serially decreased the ink levels first with the matt ink and then the
photo ink and got very close with a reduction of 5% of ink levels
compared to the levels you sent me.
