Are you using standard Epson OEM inks? If so, I have no way to explain why your cyan would be blocking more than the same ink in other K3 printers. It is possible that the OHP you are using, or the exposure unit, is giving some UV blocking that others are not getting.

BTW, you can see another example of a palladium print made with an ink separation page, this one using PK, on p. 8 of Clay Harmon tutorial on QTR.

The odd thing about this is that if you measure the UV blocking of the cyan with a densitometer that reads UV in the 370 nm range, the UV blocking of the cyan is almost as high as that of the PK and Y.

It is bizzar, i agree...
Maybe I will just change the ink??
