Frequently Asked Questions
What is a Vector Graphic and Raster Image? Generally speaking, there are two different categories that all art files can be placed into; Vector Based Graphics and Raster Based Graphics. The beauty of Vector art is that it can be blown up any size with absolutely no distortion. Raster Based Graphics, also know as Pixel-based graphics, work great when trying to show continuous tones or shading. However, because the art is pixel based, large prints may show some distortion. Below is an exaggerated example of a Vector and Raster based file. Notice how the Vector sample has crisp lines with no “blurriness” or “stair stepping”.
What is DPI? Dpi refers to the number of dots or pixels per inch and is directly related to file size. A 3″ x 5″ photograph at 72 dpi is inferior in quality when compared to a 3″ x 5″ photograph at 300 dpi. If printed “to size” one might not notice the difference, but when the image is blown up, lower dpi art is immediately noticeable.
How will my art “look” once blown up? Image quality is directly related to image size and dpi. Decreasing dpi (while keeping the image’s size constant) or increasing the image’s size (while keeping dpi constant) effect print quality in a negative way. We’re willing to go over any quality related questions before any artwork is submitted.

What is RGB and CMYK? The RGB color model uses a dot pattern of red, green and blue light to reproduce a full color image. It is used by scanners and monitors. The CMYK color model uses a dot pattern of cyan, magenta, yellow and black inks or toners to reproduce a full-color image. It is used by virtually all digital printers.
