halftone

– A negative or positive image made by photographing an image through a screen so that the detail of the image is reproduced with dots. The reproduction simulates the different tones of the original by transforming them into dots of varying sizes arrange in a grid pattern that has a given frequency.
– A photomechanical or digital process that converts continuous tone illustrations, or photographic images into a dot formation for reproduction by printing.

An exchange of signals between communications devices to verify that they are synchronized and ready for exchanging information.

handshake

– The first two-way signal exchange between two computers that determines whether or not they are connected, compatible and ready to communicate.
– A communication protocol that was established by Scitex in the 80’s as a standard method to exchange data between color prepress systems and peripherals.

hanging indent

A mass storage device for computers, usually installed inside the computer chassis, or something kept in a separate case beside it.

hard dot

A halftone dot on film that has well-defined edges with no fringe. hard dots are exposed with a laser, or made by contact with another film. Dots made with contact screen have soft edges that can cause dots sizes to vary during platemaking.

hard hyphen

A special type of hyphen that is used when the two parts of a hyphenated word should not be separated. Also called a non-breaking hyphen.

hard proof

A color proof made on a substrate directly from the store pixel data. When made directly from stored data, the hard proof is usually referred to as DDCP, where as a video monitor proof is called a soft proof.

hard return

Return codes in word processing or layout applications that are mandatory, such as returns at the end of paragraphs.

HCL

Abbreviation for Hardware Compatibility List: a list that Microsoft maintains which keeps track of the hardware that Microsoft has tested for compatibility with their Windows operating system. The list can be consulted on their web site.

HD

– Abbreviation for Hard Disk
Abbreviation for High-Density

head crash

A computer failure that occurs when the read-write head of a magnetic hard disk touches the disk usually rendering information on the disk unreadable.

head

The larger bold text at the top of a page, article or chapter.

head margin

The space between the top of the printed copy and the trimmed edge.

heatset

A web offset printing process in which ink is force-dried using an oven. The alternative technology is coldset, in which the ink is allowed to dry naturally through evaporation and absorption.

helium neon laser

A red laser exposure device, with a peak output of 632.8 nanometers, that is used for exposing red-sensitive photographic films, paper, plates or cylinders. helium neon lasers are claimed to be more stable and less expensive to purchase and operate than blue argon lasers. Nowadays this type of laser is no longer in use, being superseded by red laser diodes.

Hell angles

Rudolf Hell GmbH (first Linotype-Hell, later acquired by Heidelberg) holds several patents on screen angles. “Hell angles” generally refers to its digital halftone irrational screening algorithms. These algorithms are usually considered amount the highest quality available and are licensed by other CEPS vendors.

help files

Digital files, containing instructions for software use, that are accessed from within a software program. Help files are used to supplement the instructions contained in program manuals. Ñ

hertz

A unit of frequency equal to one cycle per second for electronic or optic signals. Abbreviated as Hz.

hexachrome

A color model which uses six primary colors (cyan, magenta, yellow, orange, green, and black) to simulate a full range of colors. Hexachrome has a much wider gamut than traditional CMYK. This makes it useful for jobs that require high color fidelity or that contain lots of Pantone spot colors that have to be matched as accurately as possible. However, printing hexachrome jobs is more expensive than conventional CMYK printing, because of the two extra colors that have to be printed. It also requires special software to handle the color separations of scans.

hexadecimal codes

A system of numbering based on “16”. The 16 “digits” include numbers 0 through 9 and letters A through F.

HFS

Abbreviation for Hierarchical File System: the file structure used when formatting a volume (disk) for use in the Macintosh operating system (prior to OS X).

hickey

A spot or imperfection in printing caused by dirt or hardened specks of ink. The problem is most visible in areas of heavy ink coverage. A hickey is also called a bulls eye or a fish eye. There are 4 of them in the image below.

high bulk paper

Paper stock that is comparatively thick in relation to its basis weight.

high key halftone

A halftone that is made utilizing only the highlight tones down through the middle tones.

highlight

The lightest area in a photograph or illustration.

high-resolution file

In a CEPS, the stored high resolution information that contains all the resolutions necessary to produce an accurately printed reproduction. A high resolution file is commonly input at a sampling rate of at least four pixels for each dot to be reproduced at the final size. The corresponding low-resolution file or viewfile is created at the resolution of the video monitor. Sometimes called high res file.

high-end

Describes device and systems that are relatively high-priced and high-quality.

high-key transparency

A very light, possibly overexposed, transparency that has most of the important detail in the highlight area and has very few shadow areas. Contrast must be adjusted differently for high-key transparencies than it is for normal low-key transparencies.

highlight

The most white portion of the original or reproduction that has no color cast. In the reproduction, it may print the smallest printing dot, the diffuse highlight, or print no dot, the specular highlight.

highlight dot

The highest density of a halftone image.

hints

Modifications built into TrueType and PostScript Type 1 typefaces to produce smoother 300 and 400spi quality output. Hints only take effect on typefaces rendered at low resolution.

H&J

Abbreviation for Hyphenation and Justification

HKS

HTTP

Abbreviation for HyperText Transfer Protocol – an application protocol for distributed, collaborative, hypermedia information systems. It is the foundation of data communication for the World Wide Web.

hue error

The amount of contamination in a process color pigment or ink that alters its appearance from that of a perfect process color. For example, because of yellow contamination, most magenta inks appear redder than a pure magenta ink, which is purplish red. All color separation software attempts to color correct for this error by reducing the dot sizes of the unwanted colors.

hue

The attribute of color that designates its dominant wave-length and distinguishes it from other colors. Red is a different hue than green. While dark red and bright red may have a different brightness or lightness, they may have the same hue.

Huffman
