Once a packaging structure and material are determined, a designer usually
receives a digital file of the packaging die from the client. The die is the blue
print of the structure or design layout and provides the exact dimensions and
product specifications. Bleed requirements and gluing specifications are
included in a two dimensional drawing to which a designer can apply brand
informations and graphics using computer software.
A die prepared for a packaging job has two parts. First is the preparation of
cutting and creasing rules which are preapred according to the size and design
of the job. Cutting and creasing rules are made of flexible steel. One edge of
the cutting rule is sharp and the other edge is blunt or thick. Both sides of the
creasing rules are blunt or thick. These rules are cut and bent into circles or
triangles or semi circles according to the size and design of the job.
