How a print job moves through the shop

The main steps from a print-ready file to finished work, and the type of machine that usually does each one. Cartons end at folding and gluing; books and notebooks end at binding.

  1. Prepress

    The artwork is checked, and each colour is imaged onto its own printing plate.

    Machines at this step: Computer-to-plate system

  2. Printing

    Offset presses print sheets of paper and board, flexo presses print labels and film from the roll, and digital presses print short runs without plates.

    Machines at this step: Offset press, Flexo press, Digital press

  3. Coating and laminating

    Printed sheets are coated or laminated with film to protect them and give a gloss or matt finish.

    Machines at this step: Laminating machine, UV coating machine

  4. Cutting and die-cutting

    Stacks of paper are trimmed to size, and carton shapes are cut and creased with a steel-rule die.

    Machines at this step: Guillotine cutter, Die-cutting machine

  5. Folding and gluing

    Die-cut blanks are folded and glued into flat cartons, ready to be filled on a packing line.

    Machines at this step: Folder-gluer

  6. Binding

    Printed sheets for books and notebooks are folded into sections, gathered in order and bound.

    Machines at this step: Paper folding machine, Perfect binder, Saddle stitcher
