I am printing Unisub coasters, and am finding some problems with cloudy/light coloured areas showing in the print.
The image below is a scan of one of my coasters with the offending white patches;
(The scan colours are off, but it does show the lighter patches.
I am printing for 65secs at 205c - as recommended on the Xpres website.
I started thinking this might be incomplete sublimation - requiring more time. However, I'm not at all sure this sis the case - and am also thinking that the relativley high temperature may be adversely affecting the blacks.
A also thought about moisture. however, I am working in a centrally heated house, so I would be surprised if this is the problem.
Could it be related to pressure? either too little, or too much?
Any thoughts would be welcome, as this is getting quite frustrating!!
