4-Color-Process:The process of combining four process colors ‹ cyan, magenta, yellow, black ‹ to create a printed full color picture or to create colors composed from these four colors. (See CMYK)
AI (Adobe Illustrator): Illustration computer graphic application. This application is used to render line art drawn in paths and allows the designer to resize images freely without getting pixilated edges as in the case with bitmapped images.
Album: A book containing photographs pasted in place.
Art Cloth Cover: Cotton fabric Fastback Hardcover. This is a bright material ideally suited for art books and professional photography books.
Bindercover: Pre-cut covers in a variety of colors.
Bleed: The part of the image area that prints past the edges of the page and is removed during final trimming.
Bond Paper: Standard office paper. Usually sold in 20# and 24# weights.

Book Block: The interior sheets of the book without the cover.
Calendering: The process giving paper a smooth finish by running the paper through smooth cylinders during the manufacturing process. Calendered paper comes in several finishes. At its calendered, paper using this process resembles coated paper in texture.
Case: Industry term for hard cover.
Case Binding: The traditional process of making hard cover books.
Casing-In: The process of attaching the hard cover case to the book block.
Clear Cover: A special plastic material designed to work well with the Fastback binders. Unlike some other plastics, Clear Cover will not melt when binding. It is also compatible with the Foilfast binder, allowing you to add foil printing to transparent covers.
Clear Liner: A thin plastic adhesive sheet designed to make book rebinding easier than ever. Ideally suited to the fast repair of non-archival books.
CMYK (Cyan, Magenta, Yellow, Black): The subtractive primaries, or process colors, used in color printing, also used to describe the printing process itself.
Coated Paper: Paper that has a fine layer of clay, resin, or some other substrate that gives the paper a smooth, often shiny appearance for rich color printing. Coated papers can be difficult to bind using standard thermal-adhesive methods. Some form of paper preparation is recommended beforehand (see Splitter, notching, milling, roughing).
CP Strip: Special thermal strip designed to let you bind books that are printed on smooth papers, or are printed with a laser printer that uses fuser oil.
Comb Binding: An older punch-and-bind system that uses a thick plastic comb. Sometimes referred to as GBC binding.
Comp Cover: Powis Parker's kidskin, paper-based and patterned material. Available in Hardcovers and in individual cover sheets for external binding.
Comp Strip: Thermal strip that matches the comp cover material in appearance. Ideally suited for special presentations of tape-bound documents.
Crash: The gauze-like material that is glued onto traditional book spines to keep the signatures together. Because the Fastback Binding System does not use traditional binding techniques, the crash (also called the "super") is not required. It is replaced with the binding strip.
Custom bookmaking: Hard cover books individually made by hand.
Debossing: A stamping process with a machine die that leaves an image pressed into the surface of a book cover. Sometimes erroneously referred to as embossing.
Die: (pl.: dies) A tool used for cutting shapes or impressing patterns in other materials. Dies are used for traditional hot stamping to apply foil, emboss paper, or both.
Die Cutting: The process of cutting a pattern in a sheet or book cover using specially-made dies.
Die-cut Window: A window on the front of a Photobook Hardcover that is cut out but not wrapped.
DPI: is the number of dots (or pixels - PPI) that fit horizontally and vertically into a one-inch measure. The more dots per inch, the more detail is captured and the sharper the image.

Full Bleed: A page that has an image that prints all the way to edges on all four sides. See also: Bleed.
Fuser Oil: Oil that is used to prevent laser printer toner from sticking to the heating element. Fuser oil can cause problems when binding because it leaves a fine layer of oil on a sheet, which can prevent the binding adhesive from coming in full contact with the paper.
GBC Binding: See "Comb Binding."
Glossy Paper: Paper coated with a slick and shiny surface. Often used in magazines, yearbooks, and photo books.
Grain Direction: The direction in which the fibers of the paper are oriented. It is important to ensure that the grain direction is parallel with the bind to achieve the best results.
Hardcover Guide: Assembly jig used to center and attach a Fastback Hardcover to a book block. It is also used to identify the correct Fastback Hardcover book widths, and to attach Foilfast Title sheets to the covers.
Headband: The narrow piece of striped or solid fabric at the top and the bottom of each book block. The headband was once an integral part of the binding process, but now it is purely decorative.

Minilab: A retail store department or kiosk that offers on-site film processing. A quick print outlet.
Newton: A unit of measurement used to measure bind strength. A newton is the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
Notching: A technique used to improve the bind on perfect-bound books. Small notches are cut along the binding edge to increase the edge area available when the book is glued. Normally it is used with coated or calendered paper to improve the bind (see, The Photobook Binding Challenge White Paper).
Offset Printing rinting technique that transfers ink from a plate to a blanket to paper instead of directly from plate to paper.
Page Turn Test: A test used to determine how many times a book page will turn before falling out. The equipment used for this test mimics the action of a person aggressively turning a page in a book.

Pixels: Individual squares of color that, when viewed from a distance, appear to make up a photographic image. The image you see on a computer screen is made up of pixels. Also referred to as raster graphics or bitmapped images.
PMS (Pantone Matching System): The Pantone matching system is used for specifying and blending match colors. It provides designers with swatches of over 700 colors and gives printers the recipes for making those colors. Pantones are generally used as spot colors, such as logos, to ensure color consistency for corporate identities. However, they can also be used in halftone graphics and for duotones. Pantones can also be simulated using the colors from the CMYK spectrum. Pantone publishes a guide for doing so. The results, however, vary greatly from the original Pantone choice, especially for greens and oranges.
Postscript: A page markup computer language designed specifically for type and graphics in page layout.
PowisPrinter: Foil printer designed to add titles to spines on tape-bound books.
Pressure Sensitive Adhesive: Adhesive that does not require heating. Powis Parker uses this type of adhesive on its Hardcover adhesive panels, Foilfast Title sheets, and Perfectback LF and PS strips.

Soft Proof ‹ proof for content via a digital file such as pdf, jpeg, etc. This is for non-color critical proofing. Press Proof ‹ proof for content and color via a printed copy. This method is usually recommended for color critical jobs.
Pull Test: A test used to test how firmly a sheet of paper is attached to its binding (see also, "Newton").
Punch and Bind: Any of the binding systems that create documents by first punching the sheets and then attaching the binding element through the punched holes (e.g. velobind or coil binding).
