Finishing touches
Trimming
Trimming is generally performed on a guillotine cutter after binding. Documents are
placed in the gutter, with the bound side away from the knife. The knife is lined up to
the desired edge of the document in position, and the knife cuts off the unnecessary
margin between the edge of the document and the edge of the paper. Three-knife
trimming machines trim the remaining non-bound edges of a publication. Trimming
brings the document to its exact pre-specified dimensions – the trim size.
Die cutting
The process of cutting specific shapes onto a page with sharp steel knives is called die
cutting. It can produce drama on the printed page and lure the reader onto the next
page to see the complete picture. It is also used for packaging applications where the
edges of the box contain specific angles for folding and gluing.
Lamination
Lamination is the process of covering a sheet with a thin layer of polyester (laminate)
to yield a strong and washable surface. Restaurant menus, for example, are laminated
for protection and washability. It is important, however, to make sure the document’s
paper and toner are compatible with the laminator. In some cases, the lamination
attracts the toner, so it looks like the text and images adhere to the laminate rather
than the paper.
