At Blockbuster Print we allow printing to the edge of the products and we take pride in having the tightest cutting margins available. These margins are 0.125" of an inch in width and 0.125" in height of an inch or 0.0625" of an inch on each side.

Example: A 4x6 postcard design should have a full canvas size of 4.125 x 6.125. When the card is trimmed down it will have a finished size of 4 x 6.

Cut & Trim Marks (this is where your product is sized to correct specs)
The product will be cut on the trim mark (blue line), however the cut may shift up to 1/16 of an inch in any direction. This is why you should design your files with that extra 0.125" bleed. Allowing for a borderless cut and print. Makes sence right?

Full Bleed (printing beyond regular product size)
If you wish to have colored backgrounds or images continue to the edge of the product, they must continue past the trim marks to the full bleed margin. Going beyond your regular size. If they do not continue to the full bleed margin you most likely will end up with white lines along the edges of the product due to cutting tolerance.

Safe Zone
The text or other elements you want to guarantee not to be trimmed off must be placed within the safe zone. If they are placed directly next to the trim mark and the cutting is off but within tolerance, the text will be chopped off.
