Glossary of Print Terms

Accordion Fold
Simple zig zag fold normally with common size panels.

Barcode
A series of vertical bars and spaces that represent any numerical series, most often a correct ZIP Code for the delivery address on a mail piece. The barcode facilitates automated processing by barcode readers and scanners. A barcode also can be used to convey information for delivery confirmation and signature confirmation services.


Bindery
The finishing department, which performs operations on the printed product after it has been printed. Some bindery operations are as follows: Folding, Binding, Stitching, Scoring, Perforation, Die Cutting, & Envelope Converting.

 

Binding
Different methods used to secure loose pages in a book is called binding. Saddle stitch is an example of binding.
Here are additional binding-related terms and definitions:

 

  • Book Block — Folded signatures gathered, sewn and trimmed, but not yet covered.

  • Case Bind — To bind using glue to hold signatures to a case made of binder board covered with fabric, plastic or leather. Also called cloth bind, edition bind, hard bind and hard cover.

  • Mechanical Bind — To bind using a comb, coil, ring binder, post or any other technique not requiring gluing, sewing or stitching.

  • Perfect Bind — To bind sheets that have been ground at the spine and are held to the cover by glue. Also called adhesive bind, cut-back bind, glue bind, paper bind, patent bind, perfecting bind, soft bind and soft cover.

  • Saddle Stitch — To bind by stapling sheets together where they fold at the spine, as compared to side stitch.

Borders

Coating
The mixture of clay materials that are applied to paper to improve the smoothness of the paper's surface and improve ink holdout during the printing process. Examples are Aqueous coating (AQ) and UV coating. UV coating adds a gloss finish to the product and also improves the vibrancy of the printed colors. Spot-UV can be applied to selected portions of the piece, while keeping the rest a matte finish.

Ghosting
A faint image that appears on a printed sheet where it was not intended. Gas ghosts occur when the previously printed image appears as a subtle "ghost" within the image of the side of the sheet after the second pass through the press. This type of chemical ghosting is caused by a variation in predicted ink drying times.


Gloss Finish

Matte Finish
A coated paper finish that is flat, not shiny like a gloss, but still keeps much of the ink from being absorbed by the paper and produces an excellent image.

Paper-related terms and definitions:

  • Acid-free Paper — Papermade from pulp containing little or no acid so it resists deterioration from age. Also called alkaline paper, archival paper, neutral pH paper, permanent paper and thesis paper.

  • C1S and C2S — Abbreviations for coated one side and coated two sides.

  • Calender — To make the surface of paper smooth by pressing it between rollers during manufacturing.

  • Caliper — (1) Thickness of paper or other substrate expressed in thousandths of an inch (mils or points), pages per inch (ppi), thousandths of a millimeter (microns) or pages per centimeter (ppc). (2) Device on a sheetfed press that detects double sheets or on a binding machine that detects missing signatures or inserts.

  • Coated Paper — Paper with a coating of clay and other substances that improves reflectivity and ink holdout. Mills produce coated paper in the four major categories cast, gloss, dull and matte.

Paper Grain
The direction in which the fibers line up during the manufacturing process. It is easier to fold, bend, or tear the paper along the same direction of the fibers. Cut sheet laser printers generally use long grain paper in which the grain runs parallel to the long side of the paper, resulting in better performance through the laser printer.


Perfector
Printing presses that can print on the front and the back of the paper in one pass through the press.


Perforation
Creating a series of holes so that the paper can be torn more easily along the line that is formed.

Postage
Payment for delivery service that is affixed or imprinted to a mail piece, usually in the form of a postage stamp, permit imprint, or meter stamp.


Pre-Press
Pre-press-related terms and definitions:

  • Alteration — Any change made by the customer after copy or artwork has been given to the printer and a proof has been produced. The change could be in copy, specifications or both. There is typically a charge for customer alterations after a press proof has been produced so it’s best if you review your files thoroughly prior to sending them to a printer to make sure they are accurate and avoid costly changes/reprints.

  • Crop Marks — thin lines placed at the corners of an image, page or artwork layout to indicate where the paper should be trimmed after printing.

  • Crossover — Type or art that continues from one page of a book or magazine across the gutter to the opposite page.

  • Digital Proofing — Preparing a sample of printed output on a computer printer before the job is printed on a commercial press. Often, the term digital proof can also be used when a printer sends you a digital file of the artwork prepared for printing through email rather than printing a proof.

  • DPI — Considered as "dots per square inch," a measure of output resolution in relationship to printers, imagesetters and monitors.

  • Imposition — One of the fundamental steps in the prepress printing process. It consists of the arrangement of the printed product's pages on the printer's sheet in order to obtain faster printing, simplify binding and reduce paper waste.

  • Page — one side of a sheet of paper in a collection of sheets bound together, especially as a book, magazine, or newspaper. Example: When you turn a page in a book you are holding 2 pages and 1 sheet of paper.

  • Preflight — The process of checking files and verifying all aspects of a print job are correct before preparing them to print.

  • Page Count — Total number of pages that a book, booklet or publication has.

  • Pre-Press — Once a client sends us their completed artwork file, including items being set up for automation or online, it goes to our prepress department. There, we check the files for all necessary functions, quality, sizing and finishing. We then prepare the files to finish appropriately for the machine(s) the product is being produced on. This includes imposing the artwork with the correct number of prints on the press sheets, accounting for gutters, tick marks, margins etc. Our prepress team ensures they set the files up to produce the optimal output in the most cost-effective manner for our customers. Our prepress department can also help with typesetting, variable data, some alterations, scanning, color management and file troubleshooting.

  • Scanning — The process of converting a document or photo into digital form. Scanning is typically done for either storage or reproduction copies of the original.

  • Sheet Count — The number sheets of paper it takes to create a product. May be helpful to include an illustration for sheet vs page count.

Self Cover
A cover printed on the same paper as the text.

 

Shrink Wrapping
A method of wrapping packages or products with a plastic film and then applying heat so that the wrap fits tight to the product. Shrink-wrapping is used to package a product in specific quantities and is also used for protection purposes. It also adds some stability to the product when storing. Also see Fin Seal.


Spiral Binding
Book binding that consists of a spiral wire or plastic that is wound through holes. Also referred to as coil binding.
