EPS vector format (encapsulated post script) is a high resolution format that printers use because the quality of the image is high. Whilst many of us are used to using images in jpeg, gif, bmp etc in everyday use, they are simply too low a resolution/quality to be assured of using when branding artwork on a promotional product.

Promotional products represent the face of your business. Just as you would take pride in your personal appearance and look your best for your customers, you want to ensure your promotional products look the best in representing your business or promotion.

EPS vector files can be generated by all drawing applications and many layout applications.

What is the difference between vector format (EPS) and other formats?

There are two types of graphic formats

1. Vector format and 2. Raster format

Vector format graphics e.g. EPS format, are based on mathematical formulae, whereas Raster graphics e.g. jpeg, gif and bmp show an image as a series of pixels.

Each format has its pros and cons, and there are times when it is better to use one format over the other.

When viewing a raster format picture, it is made up of pixels. The smaller and closer together these pixels, the better the quality of the image. If the image is enlarged, (and generally the number of pixels is kept constant) the pixels become larger, and there is less clarity of the image as individual/groups of pixels may become apparent. The file size of the image is also increased as the resolution (the number of pixels) is increased.

In vector format the image is based on a mathematical formula, so no matter what the size, the quality of the image is preserved. In fact an image in vector format can be indefinitely zoomed. It also means that the size of the image does not have to affect the size of the file. An added benefit is that details such as colour or altering of the shape can be added and removed easily from vector format artwork.
