Hairline Register: Printing registration that lies within the range of plus or minus one half row of dots. It is the thinnest of the standard printers' rules.

Halftone: in traditional publishing, a continuous-tone image photographed through a screen in order to create small dots of varying sizes that can be reproduced on a printing press. Digital halftones are produced by sampling a continuous-tone image and assigning different numbers of dots, which simulate different sized dots, for the same effect.

Halftone paper: A high finish paper that is ideal for halftone printing.

Halftone screen: in traditional publishing, the screen through which a continuous-tone image is photographed, measured in lines per inch. Although digital halftones are not actually photographed through a screen, the term is still used to describe the size of the dots; the larger the dots (fewer lines per inch), the more grainy the image. Special screens can be used for special effects.

Hang indent alignment: type set so that the first line is flush left and subsequent lines are indented.

Hanging indent: A document style in which the first line of a paragraph is aligned with the left margin, and the remaining lines are all indented an equal amount. This is sometimes referred to as outdenting. This is an effective style for displaying lists of information.

Hard dot: The effect in a photograph where a dot has such a small degree of halation that the dot shows quite sharp.

Hard hyphen: a non breaking hyphen, used when the two parts of the hyphenated word should not be separated. As opposed to a soft (or normal) hyphen, on which the word-wrapping function of a program will break a line.

 

Hard return: a return created by the Return or Enter key, as opposed to a word-wrap, or soft return, which will adjust according to the character count and column width.

Head: a line or lines of copy set in a larger face than the body copy.

Headline: The short lines of emphasized text that introduce detail information in the body text that follows. Also the category of faces that are designed to work best in headline text.

Headline font: A font that has been designed to look good at large point sizes for use in headlines. Headline fonts generally do not contain a complete set of characters since they do not require a full set of special symbols and punctuation.

Head margin: That space which lies between the top of the printed copy and the trimmed edge.

Hickey: A term used to describe the effect that occurs when a spec of dust or debris (dried ink) adheres to the printing plate and creates a spot or imperfection in the printing.

Highlights: The lightest tones of a photo, printed halftone or illustration. In the finished halftone, these highlights are represented by the finest dots.

Hue: The property of a color that allows it to be classified it by its name. For example, blue, green, and red are all hues.

HSB (hue, saturation, brightness): A color model that defines three components: hue, saturation, and brightness. Hue determines color (yellow, orange, red, etc.); brightness determines perceived intensity (lighter or darker color); and saturation determines color depth (from dull to intense).

HTML: The World Wide Web authoring standard comprised of markup tags that define the structure and components of a document. The tags are used to tag text and integrate resources (such as images, sound, video, and animation) when you create a Web page.

Hyperlink: An electronic link that provides access directly from one place in a document to another place in that document or to another document.

Hyphenation zone: For ragged-right text, an arbitrary zone about 1/5 to 1/10 of the length of the line; if a long word is not hyphenated and leaves a gap within that zone, discretionary hyphens are used to fill the line.
