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.
