Trim Marks
The product will be cut on the trim mark (blue line), however the cut may shift up to 1,61mm in any direction.

Full Bleed
If you wish to have coloured backgrounds or images continue to the edge of the product they must continue past the trim marks to the full bleed margin. If they do not continue to the full bleed margin you most likely will end up with white strips along the edge 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.
The safe zone is 3.22 mm from the edge for business cards, 210 x 148 mm postcards, letterheads and flyers. For 148 x 105 postcards it is 4.785 mm from the edge of the full bleed size.
If you choose the "rounded corners" option, you should place all elements that you do not want cut into about 2-3mm inside the safe zone to avoid them being cut into.
