RadiusCornerMoulding

The illustration at right shows a circle with a 1/2" radius aligned with the corner of a red square. The red square represents the printed piece and the red curved section represents how the square corner of the printed piece would be rounded off. In most cases, all four corners of a printed piece are rounded, but some projects have one, two, or three corners rounded.

When considering the option to round the corners of a printed piece, you will likely have several "radius" size choices. The most popular choices are the 1/2", 3/8", 1/4", and 1/8" radius. As you can see from the image below, the larger the radius, the more paper substrate will be removed to form the rounded corner-and the less "pointed" the corner will be.

Also, if a printed piece is particularly rigid, a sharp 90-degree corner may actually lead to a skin puncture or other injury. This is especially true for printed pieces that have a thick laminate applied. Hence, rounded corners are generally recommended if the laminate film is 5mil or thicker, especially if the items will be handled by children.

Flash cards, pocket-sized booklets, and presentation folders are commonly fabricated with rounded corners to help prevent the corners from getting bent backward during frequent handling.
