Sawgrass Ink - black color looking grey/greenish & colors are not vibrant

[benariela]

Hi All, I'm using the sawgrass virtuoso printer with sublijet hd inks and texprint R paper to sublimate on my dog tag substrate. currently pressing at 400 degrees for 60 seconds but for some reason the black color is appearing very dull / opaque and colors are also not sublimating as vibrant, as how they look on the print page. I have sublimated before (with an epson L3110) and have used the same temperature, time and substrate with no problem, so I'm not understanding what the issue is. I even tried pressing for 90 - 120 seconds, but the same thing happened. color black is not transferring well and colors are kind of dull / no vibrancy.

If anybody know what could be the cause of this I would be so grateful. I invested a lot of money into this printer and have been searching everywhere for an answer with no luck.
hope someone on here can give me some insight or help in any way

thanks in advance!!
