Hi! I would increse preasure too. try heavy. very heavy can you pre - press paper before you print on it? I done that once when my paper was to "wet".

hi was just reading back through my post and must of been having a blonde moment i heat for 210 seconds not 310 !!!!
we have just done another one at 185 temp for 180 seconds and the same thing happened

try pre-presed paper i think its moisture in it ooo and incrase preasure... I have this same mug attachment as you so I know what i am talking about very good press but need some preasure....

when you mean pre pressed paper do you put it in the press and heat it and at what temp and how long

press it lets say... 25- 30sec at 150C let it cool down a bit then print your designe on it.

btw. make sure you print on right side of your paper

Try filling your mug with boiling water from the kettle. Leave it for a minute, empty, THEN press your mug.
You can tape up the artwork before warming the mug.
My suspicion is you have a cheap press with small and weak heat element, the handle sucks out heat.
You get partial sublimation.

Ps. I prefere going to 200 or even 205 but fir a shorter time.
