Why we need specific file types for images

The final quality of our branded promotional item can depend on the quality of the artwork we are given to work with. Sending the wrong sort of files can have a pretty big negative impact on your finished article. In the following blog we, Tall Order Promotions, will do our best to explain the file types and why we need them.

The three letters that follow the filename. (e.g. .jpg or .eps) indicate the way the image has been encoded and compressed

The .JPG format is very popular for images that vary in tone and colour, such as photographs. As it is based on a grid (known as pixels) it is a format that is well suited for use on websites etc. However, if you were to change the size of the image it will often blur or become pixelated.  EPS is a vector format, meaning the images are saved as mathematical coordinates rather than pixels. This means that they can be enlarged indefinitely without losing quality. The relation of the coordinates to one another will not change as you enlarge the image.

Whether you want your branding on an item as small as a pen or as large as a hot air balloon you need all your images on promotional items to be good quality and clear. Therefore, we will need to manipulate the size of the artwork provided to suit the product, hence the need for a .EPS file.

Hope this information is helpful. Any other questions, don’t hesitate to ask.
