OK I had a problem with lines on images when printing on mugs and also problems with the colour, both of these I have resolved, but now I still have the problem of having grainy images. What temps and times are the best for mug printing? Maybe this is where I am going wrong I really dont know what I am doing wrong as some come out ok and some dont, and it seems to be dark colours that look grainy rather than bright colours. However text comes out perfect.

Standard settings are 180 degrees C for 3 to 3.5 minutes.

if txt looks fine it may be low resolution problems. what resolution your graphic is? i had this when printed photos taken with mobile phone.
