I have been doing laser engraving on glassware for a while now and have had some questions on wood business cards. I have read on here about different thicknesses of wood veneer that people use. I was wondering about how people transform a regular business card to something laser engraveable. Does the card have to be a vector file? Is there a way to transpose a normal card to something engraveable? I appreciate anyone's knowledge and opinions on how this is started. Thanks in advance !
