Blacks coming out brown.

[Earl Smith]

This subject has been covered many times before but I cant find the right thread to answer my problem. Can someone point me to the right post please.
Busy doing lots of things today and no time to look, thanks.

If you print with ricoh then inks may burn if to hot. In this case, black will turn more to dirty brown colour.

Am printing with Ricoh. Will try to drop temp. Its set at 185 at the mo, what do you suggest?

Thanks Paul

We use 170c and 140s for regular mug printing but if a large coverage is bright colour (e.g. neon green) then we up to 180c and 180s. Certainly 185 is too hot. Olly

THanks guys, For how long when the right temp is reached?

[UK Printed Mugs]

That would be 140s at 170c and 180s at 180c as stated previously. Olly

I do 170C for 220sec. for full wrap image on the mug.

Hi Gents, Would the above times be useful when printing the mug in the 3D Mini Sub Machine with the mug wrap ?
Maybe I have been leaving my mugs in for too long and too hot -

I have been pre heating 3D mini Sub too 190c for 200 seconds
And then placing the mug in the wrap and leaving it for 400 seconds at 190c ?

Any help would be very much appreciated.
