The Original Document
- 1.4. Document Properties
- Document Properties refers to a classification of various
components of documents as to their different tonal or color content
and as to the types of objects  they
contain. Emphasis is placed on those properties most closely associated
with documents produced on paper.
- 1.4.1. Tone
- Tone refers to the color quality or color content of the
document or parts of the document regardless of form or material content.
- 18.104.22.168 Monotone
- Monotone documents (or parts of documents) are printed or
otherwise produced using one color hue  only,
most often black or near-black.
- 22.214.171.124.1 Two-Tone
- Those parts of a monotone document that are represented in only two
contrasting tones (regardless of the hue of the color, although the
term is most often associated with black hues), with no intermediate
shades. Thus, for purposes of this Glossary, a book printed with red
ink on yellow paper would be considered two-tone. When one of the shades
is black or near- black, and the other white or near-white, the document
is described as being produced in black-and-white.
- 126.96.36.199.2 Greyscale
- Those parts of a monotone document that are presented using a range
of tones (regardless of the hue of the underlying color). The range
of tones may either be continuous (such as in aphotograph), where all possible values may essentially be taken on,
or discrete, where only a finite set of values may be taken
- 188.8.131.52 Highlight Color
- A two-tone (184.108.40.206.1) document,
parts of which additionally contain areas highlighted with a second
single color of uniform shade.
- 220.127.116.11 Two Color
- A document containing two colors, intermixed to create intervening
hues, and two extreme tones (normally black and white) used to create
a continuous or discrete (see 18.104.22.168.2) range of shades.
- 22.214.171.124 Full Color
- A document containing or attempting to contain a full range of colors,
normally of all hues, tones, and shades.
- 1.4.2. Object Type
- Object Type (see also Footnote 13) is a descriptor that conveys
information about a given sub-area (object) of the document
with regard to the manner in which it conveys data or information.
- 126.96.36.199 Text Objects
- Text Objects are document objects consisting of written or
printed (or otherwise displayed) stored words or ideograms.
- 188.8.131.52 Data Objects
- Data Objects are document objects consisting of factual information
normally arranged into datafiles (1.2.10)
or tables (184.108.40.206) which
are used as a basis for reasoning, discussion, or calculation.
- 220.127.116.11.3 Table
- See 18.104.22.168.
- 22.214.171.124 Graphic Objects
- Graphic Objects are document objects containing image information
consisting of artwork, photographs, technical drawings etc, perhaps
containing limited amounts of text usually as captions or for labelling
- 126.96.36.199.1 Line Art
- Graphic objects created entirely from the use of text, dots,
and straight or curved lines.
- 188.8.131.52.1.1 Graphs
- Line art objects consisting of representations of the interrelationships
of data in pictorial form.
- 184.108.40.206.2 Halftone
- A representation of a greyscale (220.127.116.11.2)
or color graphic object as a series of dots obtained, for example,
by photographing or scanning an image through a mesh screen. By limiting
the dots to, say, black and white (for example, by using high-contrast
film), the illusion of greyscale may be created in a two-tone or black-and-white
- 18.104.22.168.3 Discrete Tone
- A greyscale or color (22.214.171.124)
graphic object where the tones take on discrete (normally equispaced)
values within a range.
- 126.96.36.199.4 Continuous Tone
- A greyscale (188.8.131.52.2) or
color (184.108.40.206) graphic object
where the tones fall continuously across an entire range of values,
such as in a photograph (1.1.4, 220.127.116.11).
