Paper, ink, special finishes, and other items in the design line are purchased from paper and ink vendors. These materials are received and inventoried in the manufacturer's printing plant. A computer file with the digitized artwork from the design team is read by a machine that engraves the image onto a printing cylinder.
The printing cylinder is carefully inspected and fitted on a printing press. The presses use rotogravure or flexography processes. Rotogravure requires etched cylinders, while flexography uses rubber plates fitted to a rotating cylinder. The Gravure printing is used to decorate wrapping paper.
Gravure printing is used to decorate wrapping paper.
processes require inks unique to each process. Gift-wrap makers have state-of-the-art printing equipment that can apply up to six different colors simultaneously and add special finishes like foil, iridescent, pearlescent, and flocked finishes. As the paper emerges from the press, it is rolled onto large rolls and transferred to another part of the factory. Machines cut and wrap the paper in much smaller rolls for sale or format it for folding and sale in flat packages.
