Hi, recently gotten into sublimation printing and having a blast so far, but our blacks nearly always look red or brown, could this be because of heating too long?
We have a Ricoh SG 7100dn and are using sublijet r inks, jet stream sublimation paper.
Now it isn't always, for instance text can look very black but other bits are more red? Also it happens very often when using actual photos as opposed to just graphical designs.
We've been cooking at most 3 at a time for 9/10 minutes at 200 degrees.
Any thoughts? Thanks in advance
