Welcome to your ultimate guide to desktop publishing terminology in 2025. Whether you’re a seasoned designer, a multilingual typesetter, or just getting started in DTP, this glossary covers everything you need to know — from foundational layout concepts to the latest in AI-enhanced workflows and font technologies.
We’ve included both modern terms and legacy jargon (clearly marked), so you’ll always have the right language for working with clients, developers, and global publishing teams. Use this as a quick reference, learning tool, or onboarding resource for your team.
Great design starts with understanding the language of layout.
A
AA (Author’s Alteration) – Used in proofing to indicate changes made by the author or client that are not due to printer’s error and may incur additional costs.
AI-enhanced Layout – The use of artificial intelligence in automatically generating or improving document layouts. Common in tools like Adobe InDesign and Canva Pro. (New in 2025)
Alignment – The positioning of text or graphics relative to a page or margin (e.g., left, centre, justified).
Alley – The space between two columns of text. Also referred to as a column gutter or column margin.
Ampersand – The symbol for “and” (&).
Apex – The uppermost point of a character where strokes meet, such as in the letter “A”. Types include rounded, pointed, flat, and hollow.
Arabic Number – A numeral from 0 through 9. Can be styled as Old Style or Lining Figures.
Arc of the Stem – A curved stroke that is continuous with a straight stem but is not a closed bowl; examples include the bottom of “j”, “t”, “f”, “a”, and “u”. Also called a shoulder.
Arm – A short horizontal or upward sloping stroke that is not connected at one end, as seen in “L” or “T”.
Ascender – The part of a lowercase letter that rises above the main body of the letter (as in b, d, h). The part that extends above the x-height of a font.
Ascent – A font’s maximum distance above the baseline.
ASCII (American Standard Code for Information Interchange) – A universal encoding format that allows basic text exchange between different software and operating systems. It represents characters without formatting.
ATM (Adobe Type Manager) – A legacy software that rendered Type 1 PostScript fonts on-screen more accurately. (Legacy – not required in modern systems with built-in font support)
Authoring Tool – Software used to create and manage content before layout.
B
Back Matter – The book information placed after the main content. This can include the index, glossary, bibliography, and appendix.
Bad Break – Refers to widows or orphans in text layout or awkward line breaks that interrupt natural reading flow.
Banner – The stylised title design used for recurring publications like newspapers or newsletters.
Bar – The horizontal stroke in characters such as “A”, “H”, and “e”.
Baseline – The imaginary line on which most characters sit. Descenders extend below this line. Also called the “reading line.”
Bitmap – A grid of dots (pixels) used to form images or characters, common in older graphics and font systems.
Bleed – An area where images or colours extend beyond the page edge. It is trimmed post-printing to ensure the design reaches the edge without white borders.
Body Copy – The main block of text in a document, set in a single typeface and size, often with consistent line spacing (leading) and column width.
Body Type – The specific typeface used for body copy in a publication.
Bold Italic – A typestyle combining both bold weight and italic slant to add emphasis.
Bold Type – A darkened version of a typeface used for emphasis or to highlight key content.
Bowl – The rounded enclosed part of letters such as “b”, “d”, “o”, and “g”. A closed bowl connects fully to the stem, while an open bowl remains partially open.
Brackets – The curved symbols used in punctuation or mathematical notation, e.g., ( ).
Break – A division in text layout, such as a line break, column break, or page break. Breaks should support the natural reading rhythm.
Bullet – A symbol (often a dot or dingbat) used to denote items in a list or to draw attention to specific points.
C
Caching – A performance-enhancing process that stores character bitmaps in memory or on disk, so they can be reused without being re-rendered. First-time rendering generates the image; subsequent uses rely on the cached version.
Calligraphic – Refers to typefaces that mimic handwriting created with a brush or pen, often associated with elegance and fluidity. Derived from the Greek word kalligraphia, meaning “beautiful writing.”
Callout – A word or phrase in a document highlighted in larger or bolder type to create emphasis.

Diacritic – A mark such as an accent, tilde, umlaut, or cedilla that alters the pronunciation or distinguishes between otherwise similar words. Also known as an accent mark.
Dingbats – Small decorative symbols, icons, or ornaments used in place of or alongside text. Examples include bullets, arrows, stars; Zapf Dingbats is a common dingbat font.
Discretionary Hyphens – Optional hyphens inserted manually to indicate preferred line-break points within words, allowing for improved justification and readability.
Display Face – A typeface style that is larger and often bolder than text fonts, used for headlines and subheads, typically at 14pt or larger.
Downloading – The process of transferring font files from a computer to a printer’s memory so that the printer can correctly render the font.
DPI (Dots Per Inch) – A measure of resolution for printers and screens. Higher DPI values mean sharper and more detailed output; 600 DPI is standard for laser printers.
Drop Cap – A decorative element where a large initial capital letter drops down two or more lines of body copy, often used at the beginning of sections for visual impact.
E
Egyptian – A typeface style characterized by slab or square serifs and minimal stroke contrast. Also called “Western” typefaces, these originated in the 19th century and often evoke themes of Americana and bold craftsmanship. Some are so condensed they leave little space between letters.
Element – A distinct component in a layout, such as a headline, body copy, image, caption, logo, or border.
