Welcome to Photoflashgraphics "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.
