Biodegradable- The degradation of material from naturally occurring microorganisms over a defined period of time.

Board blank- A flat piece of board that has been cut and scored ready to make a box.

Bleed- Bleed is printing that goes beyond the edge of where the sheet will be trimmed. When you allow 3mm of bleed on your artwork it allows the image to run right to the edge of the page meaning no unsightly white edges.

Board Grain Direction- The orientation of the fibres in the structure of the board. The direction of the grain can be determined by checking the resistance of the board by bending it. The direction that gives the least resistance is the direction the grain is running.
