mug press cups

[bycandlelight27]

Hi,
I have just bought a Coralgraph mug press switching over from using an oven and wraps.
I can't get the mugs to press properly, can someone tell me what I'm doing wrong???

I'm doing 180/180 and have gone up to 240 seconds and 200 heat, I've also tried what feels like every combination in between!!*

I can't get the lower section of the design to transfer.

Any idea what I'm doing wrong?
