Image Resolution:

Image resolutions refers to the level of detail that any given digital design or printed product holds. The higher the resolution of your artwork when designing digitally, the sharper the image will look when it’s printed.

But how can you tell if you have right level of details in your image? Well you need to look at the number of pixels (PPI) or dots (DPI) contained within that image (we’ll come to this later). For now, though, what we can say is that image resolution is measured by the number of dots or pixels within a linear unit. So, for example, if Image 1 has 3 pixels/dots when lined up, whereas Image 2 has 9 pixels/dots when lined up, Image 2 has the higher resolution and will be a sharper, crisper image.

With this in mind, we can have a look at DPI, Pixels and Dots the standard measure of Image Resolution. EXAMPLE:


DPI, Pixels and Dots:

Quite simply, a dot or a pixel is the most basic/smallest element of an image. In the squares above, the individual coloured squares represent dots or pixels. If you zoom in really close to your artwork, pixels and dots are essentially what you will see. There are some differences between pixels and dots. However, we will focus on dots as it is the primary resolution unit used when talking about commercial printing, most noticeably in the measurement ‘DPI’

DPI stands for Dots per Inch. Referring again to the picture above, DPI is simply a measure of the number of dots that will fall side by side along one inch. So, the higher the DPI, the higher the printed resolution.

How can I change my Image resolution? What image resolution should my image have before going to print?

 Changing your resolution is easy. If you are using the most popular design program: Photoshop, then it is simply a matter of going to ‘Image’ on the top bar; then ‘Image Size’, then simply changing the resolution figure in the box that pops up. But what is the correct DPI to print with? most commercial printers worth their salt, requires 300DPI. This means that our industry leading printers 300 dots in every single inch.

So, if you can make sure your digital artwork is set at 300DPI, we will send you some of the sharpest printing you’ll ever see.

However if you do not have access to photoshop there are various websites online that allow you to convert your image into the desired DPI.  Here is a link:
