All files must incorporate a 1/8" bleed on all four sides.
"Bleed" is a printing term used to indicate the area that will be trimmed off after the job is printed and cut down to the finished size. Since the bleed extends 1/8" all around the card, your document set-up should be 1/4" taller (1/8" on top and 1/8" on the bottom) and 1/4" wider (1/8" on the left and 1/8" on the right) than the finished size of the card. The chart below indicates what the document set-up should be for a particular finished size.
Bear in Mind:
Be aware that text or images too close to the TRIM LINE (shown in SOLID PINK) will be cut off. Make sure that your background image extends 1/8" past the TRIM LINE.
In the above illustration, the background image needs to extend to the BLUE LINE. Be sure to extend the background image to bleed or the white of the paper may show in the final cut down product.
