Hi,
I've also had a problem with the mugs. I don't have your package, but everything worked brilliantly on the other press, except for the mug press! I was also at a complete loss why the colour was so dull and faded, it had spots and was brown. I worked and worked on all the settings on CS, then decided if they were perfect for all the other products, just not for the mugs why was I now changing it? I eventually (thanks to some helpful tips on here) reduced the temp and pressure and had the perfect mug..... one one side!!!!! The other side was still brown with spots. I have requested another mug press.....
But I know how you feel, I wanted to cry because the mugs were the items I knew would sell well! Thankfully I've still managed to sell the 'rejects' at cost, but it would be nice to have a decent mug though! Good luck! It is really worth reading all the other pages about the mug press
