DESIGN TERMINOLOGY
This is a glossary of many common design terms that I've compiled from various sources.

A

Acrobat
Acrobat is part of a set of applications developed by Adobe to create and view PDF files. Acrobat is used to create the PDF files, and the freeware Acrobat Reader is used to read the PDF files.

Aliasing
In graphic design, aliasing occurs when a computer monitor, printer, or graphics file does not have a high enough resolution to represent a graphic image or text. An aliased image is often said to have the “jaggies.” In other words, the edges are not smooth, but are stair-stepped or jagged.

Alignment
The positioning of a body of text. Text can be positioned to the left, right, or “center” of a page. Not to be confused with justification.

Animated GIF
A GIF graphic file, which consists of two or more images shown in a timed sequence to give the effect of motion.

Animation
Animation is the creating of a timed sequence or series of graphic images or frames together to give the appearance of continuous movement.

Anti-Aliasing
Smoothing or blending the transition of pixels in an image. Anti-aliasing the edges on a graphic image makes the edges appear smooth, not jagged.

Artwork
All original copy, including type, photos and illustrations, intended for printing. Also called art.

Ascender
The part of a letterform that rises above the x-height; the vertical stalk on the letter “h” above the rounded part is an ascender; see also descender and x-height.

B

Back Up
(1) To print on the second side of a sheet already printed on one side. (2) To adjust an image on one side of a sheet so that it aligns back-to-back with an image on the other side.

Bandwidth
Bandwidth is the amount of information your connection to the Internet can carry.

Baseline
The imaginary horizontal axis on top of which a line of text sits. A baseline grid is a grid that specifies all of the horizontal axes on a page where text should sit.

Bevel
Adding a beveled effect to a graphic image gives the image a raised appearance by applying highlight colors and shadow colors to the inside and outside edges.

Bind
Usually in the book arena, but not exclusively, the joining of leafs or signatures together with either wire, glue or other means.

Bindery
Usually a department within a printing company responsible for collating, folding, and trimming various printing projects.

Bitmap Image
A graphic image stored as a specific arrangement of screen dots, or pixels, as opposed to a vector graphic (see below). Also known as raster graphics. Common types of bitmap images include GIF, JPEG, and TIFF.

Bleed or Bleeding Edge
When a page or a cover design extends to and off the edge of the paper it is called a “bleed.” In print design, the artwork or block of color must extend off the edge of the page and printed on larger-size paper. Then the printed page is trimmed to the desired size.

Blind Embossing
Stamping raised letters or images into paper using pressure and a die, but without using foil or ink to add color to the raised areas. Braille is an example of blind embossing.

Blind Image
Image debossed, embossed, or stamped, but not printed with ink or foil.

Blueline
Prepress photographic proof made from stripped negatives where all colors show as blue images on white paper. Because blueline is a generic term for proofs made from a variety of materials having identical purposes and similar appearances, it may also be called a blackprint, blue, blueprint, brownline, brownprint, diazo, dyeline, ozalid, position proof, silverprint, Dylux, or VanDyke.

Board Paper
General term for paper over 110# index, 80# cover, or 200 gsm that is commonly used for products such as file folders, displays, and post cards. Also called paperboard.

Body
The main text of work not including the headlines.

Book Paper
Category of paper suitable for books, magazines, catalogs, advertising, and general printing needs. Book paper is divided into uncoated paper (also called offset paper), coated paper (also called art paper, enamel paper, gloss paper and slick paper) and text paper.

Bounce
(1) A repeating registration problem in the printing stage of production. (2) A customer unhappy with the results of a printing project and refusing to accept the project.

Brightness
The reflectivity of pulp, paper, or paperboard under test conditions, using a specially calibrated measuring instrument. If paper lacks brightness it will absorb too much light, so little will reflect back through the ink.

Bristol Paper
General term referring to paper 6 points or thicker with basis weights between 90# and 200# (200-500 gsm). Used for products such as index cards, file folders and displays.

Build a Color
To overlap two or more screen tints to create a new color. Such an overlap is called a build, color build, stacked screen build, or tint build.

C

Character
 A numeral, letter of the alphabet, punctuation mark, or other symbol in a font.

Checkbox
In an online form, checkboxes allow users to select multiple items at a time. By contrast, radio buttons allow users to select only one option at a time.

CMYK
Stands for the colors Cyan-Magenta-Yellow-Black. In print design, colors are defined as a percentage of each of these four colors. For example, the CMYK specification for the color black would be 0-0-0-100. In contrast, display devices (i.e., computer monitors) typically define colors using RGB.

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.

Collate
To organize printed matter in a specific order as requested.

Color Correct
To adjust the relationship among the process colors to achieve desirable colors.

Color Gamut
The entire range of hues possible to reproduce using a specific device, such as a computer screen or four-color process printing. RGB has a bigger gamut, because more colors can be displayed, than CMYK, which has a more limited gamut.

Colorfastness
The degree to which color that will run when wet or will fade in bright light.

Composition
In graphic design, the arrangement of type, graphics, and other elements on the page.

Comp / Comprehesive
A complete but prospective example of a design project, demonstrating size, layout of images and type, use of color, and paper. Also known as a dummy.

Compression
A method of packing data in order to save disk storage space or download time. JPEGs and GIFs are generally compressed graphics files. Compression is a technique to make a file or a data stream smaller for faster transmission or to take up less storage space.

Condensed Type
  A narrow or slender font.

Contrast
The degree of tones in an image ranging from highlight to shadow.

Counter
The white space within a letterform. For example, the hole in the center of the letter “o” is the counter. Some fonts have bigger counters than other; for example, Verdana has larger counters than Arial.

Cover

Creep
Phenomenon of middle pages of a folded signature extending slightly beyond outside pages.

Crop Marks
Lines near the edges of an image indicating portions to be reproduced. Also called cut marks and tic marks.

CSS
Abbreviation for Cascading Style Sheet, a feature of HTML developed by the W3C. With Cascading Style sheets, both Web designers and end users can create style templates (sheets) that specifies how different text elements (paragraphs, headings, hyperlinks, etc.) appear on a Web page. Currently, not all browsers express CSS formatting in the same manner, but CSS allows for the greatest design consistency across browsers.

Cure
To dry inks, varnishes or other coatings after printing to ensure good adhesion and prevent setoff.

D

Deboss
To press an image into paper so it lies below the surface. Also called tool.

Deckle Edge
Edge of paper left ragged as it comes from the papermaking machine instead of being cleanly cut. Also called feather edge.

Descender

Die Cut
To cut irregular shapes in paper or paperboard using a die.

Digital Proofing
Page proofs produced through electronic memory transferred onto paper via laser or inkjet.

Display Type

Print resolution usually runs from 300-1200 dots per inch on a Laser Printer and 125-225 dots per inch for photographic images on a print brochure. (For information on input device measurements see ppi.)

Dot Gain
Phenomenon of halftone dots printing larger on paper than they are on films or plates, reducing detail and lowering contrast. Also called dot growth, dot spread and press gain.

Dot Size
Relative size of halftone dots as compared to dots of the screen ruling being used. There is no unit of measurement to express dot size. Dots are too large, too small or correct only in comparison to what the viewer finds attractive.

Dots-Per-Inch / DPI

Dummy
An unprinted mock-up of a book, brochure, or "to-be-printed" piece. A dummy is made of the same paper stocks that will be used in the finished piece, and serves as a reference for the client, designer, printer, mailing, house, or distributor. The printer, paper, merchant, or paper consultant generally provides the dummy at the request of the designer. see also comp, paper consultant.

Duotone
The application of two colors to provide richer tones than a monotone (single-color image, usually grayscale) can provide. A good duotone image can simulate a wider range of the color spectrum than two colors used separately. Duotones also use a hue (color) to set the mood for a photo in a more stunning way than a full-color image can.

E

Ellipses
Three spaced periods indicating the omission of text (…).

Em Space
A lateral space equal to the width of the lower case letter "m". An em dash separates a clause.

En Space

Foil Stamp
Method of printing that releases foil from its backing when stamped with the heated die. Also called block print, hot foil stamp and stamp.

Fold
On Web sites, the fold (also known as page fold or Web page fold) is the line below which users will have to scroll to see more of the Web page. It is not an exact measurement, as each user’s browser, screen resolution, and monitor size varies. Content is said to be above the fold or below the fold. In the past, scrolling vertically was seen as a failing, but users are now quite used to scrolling; however, content users must see immediately should always be above the fold.

Folio (page number)
The actual page number in a publication.

Font
A font is a complete set of characters in a particular size and style of type. This includes the letter set, the number set, and all of the special character and diacritical marks you get by pressing the shift, option, or command/control keys. For example, Times New Roman Bold Italic is one font, and Times New Roman Bold is another font. All Times New Roman fonts together comprise a single typeface.

Gray Balance
Printed cyan, magenta and yellow halftone dots that accurately, reproduce a neutral gray image.

Grayscale
An application of black ink (for print) or the color black (for the screen) that simulates a range of tones. Grayscale images have no hue (color). In print design, a grayscale graphic image appears to be black, white, and shades of gray, but it only uses a single color ink.

Greek Copy / Greeking
Nonsense words and letterforms that are not legible, used in a design to approximate the typographic color of a page. Used primarily before final text is available for client review.

Grid
Most designers start their layouts by creating a foundational grid that acts as a skeleton or framework for placement of text, images, and other design elements. European design is often marked by obvious grid structures, whereas postmodern or grunge design has seen a departure from rigorous grid structures.

Gutter
In books, brochures, and magazines, the inside margins toward the back or the binding edges.

H

Hanging Punctuation
In proper typography, punctuation such as quotation marks and apostrophes should be set outside the justified edge of type to provide an optically even edge.

Hexachrome
A proprietary color separation process, developed by Pantone, that uses six (6) instead of four process colors.

Hexadecimal
An alpha-numeric numbering system used to specify colors on Web pages. There are three sets of two digits, each set referring to Red, Green, and Blue (RGB), for example, 000000 (R=00, G=00, B=00) would be black in the hexadecimal system. The scale goes from 0 (black) to F (white).

Interlace
Storing partial data from a single graphic image in multiple sequences. The purpose of interlacing is to have a partial image initially appear on screen rather than having to wait for the image to appear in its entirety. With interlacing, equally spaced sets of lines from the original image are stored together, and these sets appear one on top of the other in sequence.

Interleaves
Printed pages loosely inserted in a publication.

Interstitial
A Web advertisement that appears in a separate browser window, other than the target Web page. It can also refer to a microsite or Web page that acts as a bridge between two other sites.

Justification
In typesetting, justification is the setting of text or images within a column to align along both the left and right margin. Text set this way is said to be “justified.” The terms justification and alignment are not synonymous. Correctly speaking there are four recognized typographic alignments: Centered, Flush left (more accurately "flush left, ragged right"), Flush right (more accurately "flush right, ragged left"), Justified

K

K
In computer terms, stands for Kilobyte. In print design, with CMYK, the K stands for the ink color black.

Ligature
Two or more characters combined to form a single character or glyph; for example, the lowercase ‘f’ and ‘l’ next to each other often form a ligature. Ligatures are used to combine certain letters in order to avoid an ugly clash between the elements of each character. Ligatures are rarely used for headlines.

Lossless Compression
Lossless compression refers to a data compression technique where the file quality is preserved and no data is lost. Lossless compression is commonly used on GIF images, but can only reduce file size to about half of its original size.

Lossy Compression
A term coined by graphics programmers to refer to a technique of shrinking file sizes by giving away some precision of detail. JPEG is an example of a file that is compressed this way. By reducing the so-called quality of a picture when you save it, you can make the file size smaller. Many photos can take of loss of fine detail before it becomes noticeable.

Loupe (pronounced “loop”)
Magnifying lens built into a small stand. Used to inspect copy, film, proofs, plates and printing.

LPI
Abbreviation for Lines Per Inch.

Rosette
The formation created by the dots that make up four-color images. The dots, in magenta (red), cyan (blue), yellow, and black, overlap each other in a cluster.
