- Hairline Register:
Register within plus or minus one-half row of dots.
- Hairline Rule:
The thinnest rule that can be printed. Not to be used for high-resolution output.
- Halftone Dots:
The individual subdivisions of a printed surface created with a halftone screen.
- Halftone:
A method for screening to simulate shades of gray. Darker tones are created with larger dots; lighter tones with smaller dots. This reproduction method contrasts with stochastic screening (same-size microdots) in a controlled random placement within a given area.
- Hard Dot:
A halftone dot that has a hard, crisp edge without the fringe seen with the soft dot. The hard dot also has a fairly uniform density over its entire surface.
- Hardcopy:
A printout, either low or high-resolution, accurately representing the electronic file.
- Head Trim:
Area that is trimmed off at the top of a piece during the binding process.
- Head:
The top of a card, page or book.
- Hickey:
Spot on a printed sheet usually due to dust, lint or bits of paper.
- High Folio Lap:
Lap appears on higher numbered pages of a four-page insert. Inserts with high folio laps usually jog to the head.
- Highlight:
The lightest area of a photograph that has the smallest or fewest dots when made into a halftone.
- Hone Off:
An image that is removed on press.
- Horizontal Bars:
Printed bars under the indicia on a BRM card. Horizontal bars must be at least 1'' wide and cannot go below the bottom of the second-to-bottom line in the address.
- Horizontal Justification:
The ability to condense and expand character width any percentage value so right and left margins are flush.
- HSV:
Abbreviation for Hue, Saturation, and Value; a color model used in some graphic design programs. Images in HSV must be translated to another model for color printing or for forming screen colors.
- Hue Error:
Characterizes colorants used as process colors. Expressed as a percentage, hue error indicates the deviation from a theoretically perfect process hue. It does not, however, indicate any error or problem with the process links.
- Hue:
The main attribute of a color which distinguishes it from other colors. Hue is determined by the color's dominant wavelength within the visible spectrum. Saturation and brightness are two other attributes of color.
