Sublimation Test (note this is what works for us and we are sharing the knowledge for you to give it a try and see what works for you).
We are using extruded perspex/acrylic which does not like the heat that much.
- Test done 180 deg for 30sec.
- Do not mirror image so the design can be seen from the front (only on clear acrylic)
- Lightish to medium pressure.
- Immediately remove from heat press, becarefull it is hot.
- Then remove the sublimation paper of what you can remove.
- Then place under heavy weights for at least 20min so it can go back to shape.
- Once cooled and returned to shape then scrub the back with a kitchen sponge, rough side with water to remove what is left of the sub paper.
Note this is what works for us and we have done various test to get the right time be used on extruded acrylic. Any more time spent in the heat press will melt the acrylic and go out of shape and warp.
Note cast acrylic can withstand much more heat and 180 deg for 180 secs works well on this type of plastic and with stands it shape.
