"Glossary of Graphic
Terms."
Graphic Design
Arrangement of type
and visual elements along with specifications for
paper, ink colours and printing processes that,
when combined, convey a visual message.
Graphics
Visual elements that
supplement type to make printed messages more clear
or interesting.
Grayscale
A sequence of shades ranging from black through
white, used in computer graphics to add detail to
images or to represent a colour image on a
monochrome output device.
Hue
A specific colour such
as yellow or orange.
Indexed Colour
Indexed formats are formats which are mapped to a
smaller colour palette - 256-colours or less. All
GIF images - whose bit depths can range from 1 to 8
- are, by definition, indexed images. In an indexed
image, colours are stored in a palette, which is
sometimes referred to as a colour lookup table. The
indexed image's palette contains all of the colours
that are available for the image.
Layout
A
sample of the original providing (showing) position
of printed work (direction, instructions) needed
and desired.
Layered
In Photoshop, a layer
is a section of information within a file. For
example, a RGB file consists of at least four
layers: the combined RGB layer, a Red layer, a
Green layer, and a Blue.
Leading
Amount of
space between lines of type.
Logo
(Logotype)
A company, partnership
or corporate creation (design) that denotes a
unique entity. A possible combination of letters
and art work to create a "sole" entity symbol of
that specific unit.
Lossless Compression
The process of compressing a file such that, after
being compressed and decompressed, it matches its
original format bit for bit.
Midtones
In a photograph or
illustration, tones created by dots between 30
percent and 70 percent of coverage, as compared to
highlights and shadows.
Multichannel
Colour mode in which each multiple channel in
Photoshop uses 256 levels of gray.
Pickup
Art
Artwork, used in a
previous job, to be incorporated in a current
job.
Positive
Film
Film that prevents
light from passing through images, as compared to
negative film that allows light to pass through.
Also called knockout film.
Proof
Test sheet made to
reveal errors or flaws, predict results on press
and record how a printing job is intended to appear
when finished.
Res-up
The process of increasing the size of a compressed
graphics file to a high resolution image with tools
like Genuine Fractals PrintPro from
LizardTech.
Resolution
Sharpness of an image
on film, paper, computer screen, disc, tape or
other medium.
RGB
Acronym for red-green-blue. The three colours of
light which can be mixed to produce any other
colour. Coloured images are often stored as a
sequence of RGB triplets or as separate red, green,
and blue overlays though this is not the only
possible representation (see CMYK).
Scale
To enlarge or reduce a graphic display, such as a
drawing or a photographic image, by adjusting its
size proportionally.
Sharpening
In Photoshop, a variation of a traditional
compositing technique used to sharpen edges in an
image. It is useful for images intended both for
print and online.
Subtractive
Colour
Colour produced by
light reflected from a surface, as compared to
additive colour. Subtractive colour includes hues
in colour photos and colours created by inks on
paper.
Tint
Screening or adding
white to a solid colour for results of lightening
that specific colour.
Visually Lossless Compression
The process of compressing a file such that some
data is lost after the file is compressed and
decompressed, although the loss is not detectable
to the eye.
