Not sure what exactly you are asking.

Do you mean is it possible to print onto any M7 or do you mean can we print for you?

I think you could probably print onto light colours in much the same way as subbing onto polyester shirts.

Inks are expecting to be placed on a white background so colour shift occurs and it's best to stick to single print colours. We use only solid red or black on operation labels / safety signs.

If you are looking for someone to produce for you you might find a local sign firm willing to help.

BTW - the M7 range has just had some new colours added. Metamark will send you a swatch book free of charge.
