postpress

Postpress refers to the stage after printing, encompassing finishing, binding, and packaging operations that transform printed sheets into finished products such as books, magazines, brochures, catalogs, and packaging. It follows prepress and printing within the production workflow.

Core postpress processes include cutting and trimming, folding, scoring, perforation, gathering, and binding. Binding methods range from saddle stitching and perfect binding to case binding, comb or spiral binding, and tape bindings. Additional finishing steps include laminating, coating (varnish, UV, aqueous), foil stamping, embossing and debossing, and die-cutting to create shapes or windows. Final touches may involve padding and packaging.

Equipment spans guillotines, trim and cutter systems; folding machines and folders; creasers and scoring devices; binding lines for saddle stitch, perfect bind, and case binding; lamination and coating equipment; die-cutters and foil presses; and packaging lines. Digital postpress devices enable short runs and rapid turnaround.

The postpress stage impacts product aesthetics, durability, and usability, and it often requires tight coordination with cutting plans and quality control to ensure correct size, alignment, and finish.

Environmental and standards considerations include waste minimization, recycling of paper and waste streams, and adherence to industry standards for color and finish.
