Paresh quoted the following from the book 'From Design Into Print': Preparing Graphics and Text for Professional Printing by Sandee Cohen:
Production:
When in the process of designing a package it is essential that you consult with your printer, binder and possible material suppliers, regarding the technical aspects of producing your design.
Apart from cutting, scoring (creasing), and folding, pay attention to printing bleed requirements and glueing.
Before production, it is strongly recommended that you have a mock-up made, using the final material, with the exact measurements of the final work.
