Often, when our customers begin the process of submitting designs for printing, we find that there is confusion regarding the type of art that we need to receive from them. The confusion seems to center around Vector graphics files. Most people who are not professional graphic designers do not know what Vector art is. Indeed, there are even some people working as graphic designers, who do not know what vector graphics are.
We'll try to describe, as best we can, what vector art is, and how to recognize it.
First off, vector art is created using vector illustration software programs, such as Adobe Illustrator or Corel Draw. These programs use mathematic equations and geometric primitives (points, lines, and shapes) to create art that is clean, camera ready, and can be scaled infinitely, without any loss of quality or fidelity.
In the featured graphic, you'll see the difference between Vector art and the other, more common type of computer graphic, Raster art.
You’ll notice how, in the Raster art file, the edges of the art become distorted when the picture is enlarged. You’ll also notice how there are hundreds of shades of green in the Raster file, but only one shade of green in the Vector file.
Raster Graphics, such as photographs, and graphics files created in Adobe Photoshop, Paint Shop Pro, and other Raster editing programs, can be used for some screenprinting applications, such as printing one-color pen and ink drawings. But in most cases, especially with art such as logos, we will need Vector art to achieve the proper print.
