Yes, not only do we know what bleed is, we can incorporate it into your design!
If you are designing a typical business card that is 3.5′ x 2″, you can ask your designer to account for bleed, typically 1/8′ on every side. If you have a different measurement in mind, please tell your designer!
If you want to incorporate the bleed into the dimensions yourself for the business card (3.75″ x 2.25″), simply tell your designer you already accounted for bleed into the dimensions of the card.
