I am using a Mug press machine GS-201T - 220v - 350w+350w
a Ricoh SG2100N Aficio and 11oz white ceramic mugs.
i have been using these machines for a few months now and have seemed to have a lot of different problems with them. however i have been trying to print out several different orders/designs that have black in and although i will do tests on one design and find the perfect settings for that one, when i then try to do another design with black in it will come out brown/blurred? so i find myself having to do this for each design to get it to come out right which means i am losing a lot of mugs with a few tests each time.
However i have a few designs at the moment that whatever i seem to do it will just not come out right??
The settings that have worked well for most designs are 180 for 120 seconds with medium pressure or around this. i started at 180 for 3 mins and have worked down with time and pressures and can normally find one to suit but i am struggling now.
the only thing i can think is that we have been changing mug supplier due to a high number of orders when our suppliers have been all out of stock so having to find different ones. however sometimes it is the same mug that is used and still does not seem to work.
we have tried heating the bottom of the mug first by pour boiling water in to fill around 1 inch and that worked for a while but still ends up not looking right!
why would this not work for all designs? any ideas??
