View Larger Map Raster Graphics bitmapped images, with structure consisting of a grid of pixels. each pixel has a single defined color and they are resolution dependant, meaning they cannot scale to a lerger size without loss of image quality. common file types are .bmp, .jpg, .tif, .gif, and some .eps and .pdf files. Vector Graphics uses geometric primitives to form point,line, curve art. can be scaled almost infinitely without loss of quality. where raster graphics are like building an image of legos, vector art is like an image made by connecting the dots. common file types are .ai, .eps, and .pdf. Pantone Color Matching Our printing system utilizes a Pantone Color Patching system. We ask that if you are submitting artwork for output that needs to match a pantone color, that you use the Pantone Solid Coated swatch library in your art files to ensure color accuracy. Resolution Guidlines A good way to determine the proper resolution for a file intended for print is to consider the ultimate viewing distance. The diagonal distance across the final print is a fairly typical viewing distance. You shouldn't be able to see any individual pixels when viewing from that distance. You can reduce the resolution until you reach this breaking point to reduce file size and to speed up processing time.
