With advancing image technologies, certain variations have been noticed in the way from which we used to see and improve images.

PDF format being the main format we require for artwork specifications in order to produce best quality images on the custom prints, other file types such as JPG, JPEG, PNG, PSD etc. are commonly provided however all of these serve different purposes and are not always qualified to be used for certain custom prints due to the quality and resolutions of the image. In short, we prefer Vector images instead of Raster images.

2 COMMON TYPES OF FILES

Vector Vs Raster

There are two significant types of image files: Raster and Vector. Raster images are created with pixel-based programs or created with a scanner or by photography. They are commonly used among image formats in general such as jpg, gif, png, and are generally used around the whole wide web. Vector graphics are created with vector software and are common for images that will be applied onto a physical product.

Raster (Psd, jpeg, PNG, gif, tiff) (made up of pixels)
images are made of many pixels. A pixel is a single point or the smallest single component on a display device, gadget, computer etc.
If you zoom in to a raster image you should start to see masses of little tiny squares that altogether make up the entire image. The image becomes more and more pixelated as you zoom in.

Vector(ai, eps, pdf) (made up of paths)
Images are accurate mathematical calculations that are made up of points. These points are connected from one point to another that form lines and shapes that combine into the image you wish. If you zoom into a vector graphic it will always look the same.
The image will remain sharp with clean and smooth edges, never pixelating or breaking form.More Information on How to Supply Your Artwork In The Correct Format.

Vector-vs-rasterised - Same Day Printing

To ensure the best looking print, always aim to provide a Vector file of your logo or image. If you only have a Raster file, aim to provide one at the highest resolution possible and 1:1 scale.

Sometimes you may have what you think is a Vector file (ai, eps of pdf), however it is just a Raster file placed in a Vector format!

The way to tell if your image is Vector is to use your pdf or image viewer to zoom in on the image. If it stays crisp, its a Vector. If it begins to appear fuzzy, its a Raster
