  • 1. GLOSSARY OF PRINT TERMS A A-sizes: main series of finished printing trimmed sizes in the ISO international paper size range. A0 - 841 x 1189mm A1 - 594 x 841mm A2 - 420 x 594mm A3 - 297 x 420mm A4 - 210 x 297mm A5 - 148 x 210mm A6 - 105 x 148mm Acetates : clear overlay with black and/or colour type. Used for presenting covers and concepts to client. Additive Primaries: in reproduction, red, green and blue; at an equal share of value they produce the sensation of white light. Adhesive binding: (see also Perfect Binding) Type of threadless binding in which the leaves of a book are held together at the binding edge by glue or synthetic adhesive (see also P.U.R. Binding). Against the Grain: Folding paper at right angles to the grain direction of the paper. Artwork : text, graphic and illustrations arranged individually or in any combination for subsequent printing. Ver y rare these days. Artwork is a bit of a misnomer as they are computer-originated, and supplied as digitised data on a disk or other means of electronic data. It then goes to the Repro stage or reprographic colour separation to use its full title. This enables the separation to be printed in the four basic printing process colours (cyan, magenta, yellow and black). Ascender: In typesetting, the part of a lower case letter which rises above the main body, as in the letter "d". ASCII: American Standard Code for Information Interchange. This is a standard coding system within the computer industr y to convert keyboard input into digital information. It covers all of the printable characters in normal use and control characters such as carriage return and line feed. The full table contains 127 elements. Author ’s Corrections: Corrections made by the author on proofs, that alter the original copy. The cost of making such alterations is charged for, in contrast to printer ’s errors or house corrections. B B sizes: ISO international sizes intended primarily for posters, wall charts and similar items where difference in size of the larger sheets in the A series represents too large a gap. B0 – 1000 x 1414mm B1 – 707 x 1000mm B2 – 500 x 707mm B3 – 353 x 500mm B4 – 250 x 353mm B5 – 176 x 250mm Backing Up: Printing the reverse side of a sheet already printed on one side. Binding Editions: detailed documents, supplied by client, which include binding directions, cover information, ink-jet keys, postage or address information, inserts and wrap information, quantity and mailing dates. Bimetallic: Plate in lithography, a plate used for long runs. The printing image base is usually copper and the non-printing area is aluminium or stainless steel. Bind-in Order Forms: (a.k.a. mail order blanks or MOB'S) binds into the centre of the book or is part of the wrap cover. Bit: In computers, the basic unit of digital information. It is a contraction of. BInar y digiT (BIT). Bit Map: In computer imaging, the electronic representation of a page, indicating
  • 2. the position of ever y possible spot from 0 to 100 and rest from other document. Black and White: Originals or reproductions in single colour. Blade coated mechanical: The base uncoated stock is covered in a wet coating and the excess is removed by a thin flexible metal blade leaving a uniform thin gloss coating on both sides of the paper. Generally off-white in colour. Blanket: In offset printing, a rubber surfaced fabric that is clamped around a plate cylinder. Bleed: When the printed image extends beyond the trimmed area of a page. Blind Embossing: A design, which gives a bas-relief effect, without ink. Block: In binding, to impress or stamp a design upon the cover. The design can be blocked in coloured inks, or metal foil. Blowup: A photographic enlargement. Blueprint/Blue-line: in web-offset lithography, a photoprint made from strippedup negatives or positives used to proof check the position of an image on the page and imposition generally. I'm not sure what it means either. Bond Paper: A grade in writing or printing paper; usually used for letterheads or business forms. BPOP: Bulk Packed on Pallets - A method of packing finished printed products in which they are not wrapped in parcels but stacked onto pallets, usually turned in equal quantities. Finished pallets are then wrapped in plastic film. Broadsheet: Any sheet in its basic size (not folded or cut); also denotes a newspaper size. Bromide: A photographic paper used in graphic reproduction, phototypesetting on which a photographic image is created. Bulk: Relative thickness of a sheet or sheets, for example, a bulky paper and a thin paper both of the same weight display different "bulk" or ''thickness''. Bump Exposure: in the plateroom, an exposure in halftone especially with contact screens, in which the screen is removed for a short time; this increases highlight contrast and drops out the dots in the whites. C Camera Ready: art or copy ready for reproduction. Case: in bookbinding, the covers of a hardbound book. CD-ROM: an acronym used for Compact Disc Read-Only-Memor y. A CD-ROM drive uses the CD format as a computer storage medium. Cheating-the-Plate: Usually a fall back position when you’re not getting anywhere on press. By either under exposing a new plate (making more dot and therefore colour be there) or over exposing the plate (lessening the dot and therefore colour a press) tr ying to get an acceptable result. Not ideal but has saved many on occasion. More difficult with CTP. CMYK: Cyan, Magenta, Yellow, Key(black) subtractive primar y colours - used as the basic colours in the printing industr y. Coated Stock: paper having a surface coating which produces a smooth finish. Cold colour: in printing, a colour with, a bluish cast. Colour Correction: any method, such as masking, dot-etching or scanning, used to improve colour rendition.
  • 3. Colour Proofing: this term describes a wide range of techniques which have been developed to reproduce full colour images from film or digital data available, prior to the actual print run; thus allowing the client, colour separation house and printer to view the “proofed” result, prior to the actual print run. Colour Separation: in photography, the process of separating colour originals into the primar y printing colour components, in negative or positive form. Concertina fold: a method of alternate folding, so that when opened out the finished product is folded in a zigzag fashion. Rather like a, er, concertina. Contact Print: a photographic print made from a negative or positive in contact with sensitised paper, film or printing plate. Continuous Tone: a photographic image which contains gradient tones from black to white Contract Proof: a coloured, hard copy representation of the printed image, made from the films, which will be used to make the final printing plates. The word “contract ” comes from the fact that, when signed by the client, a contract is formed, which states that the final printed job should be a close match to the contract proof. Contrast: The tonal gradation between the highlights, middle tone and shadows in an original or reproduction. Cromalin: an off-press electrostatic colour proof. DuPont trademark used as a generic term, rather like Hoover for electrostatic proofs generally. Crop: to eliminate portions of copy or art indicated on an original by cropmarks. Crossover: when a photograph crosses gutter from one page to another. CTP: Computer on to Plate. A fully digital way of producing Plates where digital files are manipulated in to the dot formation needed to print from and then a Plate is produced from this.

Apple Mac and Quark Express are to preferred hardware/software in the industr y. Die-Cutting: the process of using sharp steel rules to cut special shapes. Diestamping: An intaglio process of printing in which the resultant impression stands out in relief above the surface of the stamped material, either coloured (using inks) or blind (that is, without colour): relief stamping. Digital Colour Proofs: an off-press colour proof produced from digital data without the need for separated films. Direct Imaging: A term used with presses that need no plates, as the image to be printed is in fact created within the press, usually by laser onto a sasitised roller. Dithering: a technique of filling the gap between two pixels with another
  • 4. Pixel having an average value of the two to minimise the difference or add detail to smooth the result. Dot: the individual element in both halftones and four colour process printing. Dot Etching: In separations, chemically reducing halftone dots to var y the amount of colour to be printed; dot etching on negatives increases colour, dot etching on positives reduces colour. Dot Gain: In printing, a defect in which dots print larger than they should, causing darker tones and stronger colours. Doubling: The appearance on a printed product of the non-coincidental images obtained at one impression. Dots Per Inch (dpi): a measure of resolution on the printed page. Drawn-on Cover: a paper book cover which is attached to the sewn book by gluing the spine. Duotone: a two-colour halftone reproduction from a one-colour photograph.

Section: see Signature Selective Binding: by demographically binding a printed product this data triggers the appropriate sections from a range of available sections automatically to produce a product unique to that data input (and therefore more relevant to the end recipient). Serif: the short cross-lines at the ends of the main strokes of letters in some type faces. Short grain press: a press where the shortest side of the finished product runs parallel to the grain of the paper. Shrink wrap: method of packing printed products by surrounding them with plastic, then shrinking by heat.

Stock: paper or other material to be printed. Stochastic screening: also known as FM (Frequency Modulated) screening.
  • 10. With conventional halftone screening, the variable dot size formed, creates the optical illusion of various tonal values; however, the dot centre pitch distance is constant. In the case of FM screening systems, the dots are randomly distributed to create this tonal change illusion. The greater the number of dots located within a specific area, the darker the resultant tone. The dots produced in this way are usually smaller than conventional halftone dots, resulting in improved definition, although greater care and attention to detail is required in platemaking stage. Stripping: in offset lithography, the positioning of negatives (or positives) on a flat to compose a page or layout for platemaking. Substrate: the piece of material printed. Subtractive Primaries: yellow, magenta and cyan, the colours used for process colour printing inks. See CMYK.
