 I only tried the old (plain Premium TPU100) once and gave up trying to do MK ink -  like you I was also trying to get a better opacity for printing out paper.  Never tried on the new Utlra one.  

Also, apologies to the OP - I see I missed that my question about which transparency was already answered earlier - HP Clear Film.  They seem to claim it is good for both pigment and dye inks.  No idea how it performs on an Epson - could have some compatibility issues.

Actually I use MK ink with Pictorico ULTRA PREMIUM film and I raise the ink density specifically on Pictorico but it still dries perfectly in a few hours if I just hang it up.  And I live in the tropical humidity of Barbados.  I do this because I use these particular negs for uranotype printing which has one of the longest scale indices (seems longer than salt).

 When you say acetate negative, do you mean one that is designed for inkjet printing specifically like Fixxons or Pictorico - just trying to make sure.  Those and others have a special coating to receive the ink.  Also, please check that you are using PK and not MK ink by any chance, the latter will take very long to dry for sure if not for days - will also run or smudge.

 I'm printing large cyanotypes (60"x24" typically), and I'm now printing
acetate negatives on an Epson SureColor P9000 which produces beautiful
negatives, but the negatives don't dry completely-- for days. I'd welcome
any suggestions. Heat? Chemical treatment?
