Phone Cases marked, 'water marked' possibly 'burned' markings? Any Ideas/Help Please

[Mike5587]

Hi Everyone,

Am new around here and releatively new to dye sub but have a reasonable understanding of the basics. I'm printing phone cases on a blank white glossy case and am having this horrible effect on the finished product that I can't see to shift or work out what it is. I kind of looks like 'water staining' or a burn mark, or possibly a printing issue, I'm just really not sure. I've seen a thread or two on this topic before but not really with a solution.
I'm using a Rochi SG3110, sublijet R ink, Jet stream transfer paper and a 3d vacuum press. Settings I've seemed to find best at the moment 195 degress for 6 minutes. I use powerdriver 4 for my printer profile via photoshop.

I've seen some people suggesting time/temp/pressure settings, some people saying ICC profile, some people saying case quality.... I'm just really lost and desperate for some more expereinced users' help! :)



Thanks in advance,

Mike
