NOTE: Colours shown are for indications only and may not match the actual Metamo colour.
It is important that the normal colour under the Metamo print is the same colour but a lighter shade than the Metamo ink used. It is difficult to say, for instance, to cover Red Metamo over Black normal print as the Black tends to show though. Metamo colours may vary slightly during production.
Should a colour mug be used (as opposed to the normal White mug), then the hot liquid poured into the mug and the Metamo inks change, a greyish haze will be left over the top of the normal print. The characteristics of the Metamo ink makes this unavoidable.
The Metamo covering over normal inks will be applied at the factory's discretion to give the maximum effect.
