Vector Artwork
Please provide Vector artwork for logos and text, it is required forour production purposes to produce high-quality graphics in print with smooth edges.
Vector drawings are comprised of floating anchor points set at specific coordinates on a page with segments connecting them together, creatinga framework of paths. They can easily be repositioned and re-shaped, aswell as their colour changed with a click of the mouse.
The logo below was drawn using vector tools. It has smooth edges, softcurves and sharp corners. The quality never diminishes because it is resolution-independant.
Example of a vector logo with yellow fill.
Bitmap Artwork
Bitmap artwork is permitted only if it is to be used as a photographiceffect. Bitmap, termed for a "map of bits", is a rectangular grid thatmake up an image. Like checkerboards or parquet flooring, these gridsare made up of little squares called pixels or samples.
A bitmap image is resolution-dependant, which means the quality of theimage is affected by how small the pixels are and how many are in the image. The higher the resolution, the better the quality of the image and the more details it will contain. The resolution is calculated according the number of pixels within a square inch.
Please note that the quality of an image cannot be improved byincreasing its resolution because the bits of information required for filling in the finer details is
missing.

Examples of a color bitmap logo.
|
| The resolution of this logo is too low
for tracing because the details are missing, and
looking at it close up is strenuous to the eyes. |
|
| The resolution of this image is not
very high, but is adequate for tracing. |
