Die-cutting is a paper cutting process which is done to achieve a special design shape for covers, presentation folders, cards, and packages. A die-cut process is essential to give a final shape to the package, and it is a process that is done before binding and pasting the package.
The die-cut artwork must be done with any Pantone color, as it will let the printer know that it is for die-cutting. The artwork printing file is 2D, but if you want to check the final 3D package shape and design for mass products, you must request for a sample. Lastly, you must also see to it that the folding lines are straight with die-cut so that the final product looks neat.
