Ok to start, I know this isn't related to dye sublimation. But I'm tearing my hair out with this;
I am having a repeat of an issue i had a few years ago now, where I'm printing full colour, and the black is coming out sort of matt looking and not properly fixed to the page, and rubs off and easily scratched off. Another thing I've noticed is in a certain light it is reflective and looks silver?!
I'm using an Epson 1500w inkjet, cis with pigment inks from city ink express, onto self adhesive inkjet glossy vinyl from photopaperdirect. I havent changed profiles / printer settings at all for a long while. I was having this issue with pigment black back in 2015 when using different inks in my set up so on recommendation went back to using cie inks which till now have worked perfectly, haven’t had an issue.
Just wondered if anyone could throw any light? As far as I know nothing has changed in my print settings/ machine set up so I was pointing the finger at either the cie inks having changed somehow (but don't appear to, still using inks labelled pigment and they've since confirmed its impossible ink has been labelled incorrectly) or, the photopaperdirect vinyl inkjet media I buy has maybe changed (glossy self-adhesive vinyl paper). I've asked them if that's possible awaiting a reply.
But just in case you can immediately think of anything else that might be causing the symptoms I mentioned?
ANY thoughts help or things to try greatly appreciated as I'm desperately needing to create existing orders backlog.
