To avoid incorporating additional costs into your job, we request that any supplied artwork is given to us in accordance to our artwork submission guidelines. We work with two differing graphic types; Raster (contones) and Vector (line work).

Raster Graphics

A raster graphics image, digital image, or bitmap, is a data file or structure representing a generally rectangular grid of pixels, or points of color, on a computer monitor, paper, or other display device. The color of each pixel is individually defined; images in the RGB color space, for instance, often consist of colored pixels defined by three bytes—one byte each for red, green and blue. Less colorful images require less information per pixel; for example, an image with only black and white pixels requires only a single bit for each pixel. Raster graphics are distinguished from vector graphics in that vector graphics represent an image through the use of geometric objects such as curves and polygons.

Raster graphics cannot be scaled to a higher resolution without loss of apparent quality. This is in contrast to vector graphics, which easily scale to the quality of the device on which they are rendered. Raster graphics are more practical than vector graphics for photographs and photo-realistic images, while vector graphics are often more practical for typesetting or graphic design. Modern computer monitors typically display about 72 to 130 pixels per inch (PPI), and some modern consumer printers can resolve 2400 dots per inch (DPI) or more; determining the most appropriate image resolution for a given printer resolution can be difficult, since printed output may have a greater level of detail than can be discerned on a monitor.

Vector Graphics

Vector graphics (also called geometric modeling or object-oriented graphics) is the use of geometrical primitives such as points, lines, curves, and polygons, which are all based upon mathematical equations to represent images in computer graphics. It is used by contrast to the term raster graphics, which is the representation of images as a collection of pixels (dots).One key aspect of vector art is key for printing. Since the art is made from a series of mathematical points it will print very crisp no matter how much the art is resized. For instance you can take the same vector logo and print it on a business card or blow it up to billboard size and keep the same crisp quality. In contrast a raster graphic would blur incredibly if it were blown up from a business card size to billboard size.

How should I supply my imagery ?

In general, any large format image should be printed using vector data as much as possible. Photographic images should be rasterised at a very minimum of 150dpi, in CMYK colour mode, and at 1:1 scale.

Vector graphics should be supplied as an Adobe Illustrator compatible EPS file and all text should be outline/converted to paths or points.

Rasters should be supplied as a TIF (Targa Image Format), at 300dpi if possible, and at 100% scale.

Note that anything that will be cut (either vinyl material, wood/aluminium etc) should be drawn as a vector. Any re-drawing or editing of artwork due to supply of artwork not in accordance with our submission guidelines is chargable.
