Problem with SCP800

[abozakaria]

Hi all
I have Epson P800 printer and iam using ConePro ink with it and I was very satisfied with results(Sharp vivid prints) until before about 6 weeks I notice  prints comes out not sharp when I print a colormunki profile I notice colors in some patterns near black smears (PLZ see images attached) and also dark blues not smooth
as you know we always refile with ink and I feel that some of new ink bottles may be bad ink
I contact inkjet mall support for more than one month and he didn't figure where exactly the problem
I think one ink color may be bad >>but how to know exactly what color <<
is there a rip or some thing else software I can exactly print one of the 8 colors of the Epson p800 in order to figure where is the problem

You can download free color purge files here:

They have a set of single-color files and one that includes all eight colors in one file (the black, of course, is either PK or MK depending on which is currently in use.)
