(Wire-o and Coil)

Front and back covers have 0.25” of bleeds on all sides. Front cover and back cover are placed side by side (without any space between) centered on a static canvas size of 18” x 11.5”. The dashed line above represents the cut line between the front and back cover. For trim sizes larger than 8.5 x 11, please contact your BNB Customer Service Representative.

Please do not include crop marks, color bars, registration marks, document info on the covers.

Coil/Wire-O Bound Tips

Please leave extra space on the binding edge (dashed line) for the coil/wire-o holes to be punched. Avoid placing text or other important content closer than 0.5” from the binding edge trim line, as this area is where the holes are punched for the binding.

Mechanical bound covers such as these can utilize two-sided lamination for enhanced durability.

Both front cover and back cover images are the same size, without spine. They abut each other, centered on the 18” x 11.5’ canvas.
