Q1: Do we always need tray when we print on different kinds of food(cake,chocolate,macarons,marshmallow,lollipop,cookies,bread,biscuit and so on)
A: No, we don’t. But with tray, it will be more convenient. We can use edible paper instead of the tray itself, like this we can get the trays function, but will waste edible paper, just like this. Tray images above marked NO.7, NO.8 and NO.9, they use paper instead of tray.
