Paper folds cleaner and runs smoothly through offset and digital presses parallel to its grain. Align grain along book spines and box creases.
Offset presses require 0.25″ to 0.375″ (6mm–10mm) margin along the gripper edge where mechanical fingers grab the sheet.
When designs have full bleed artwork extending to the edges, use at least 0.125″ (3mm) blade gap for clean double trims without color bleeding.
