DPI = Dots Per Inch - The More The Merrier For Clarity of Print
DPI refers to “dots per inch” indicating the resolution of an image. The more dots per inch, the higher the resolution and the better quality the image.
In printing the dpi resolution is very important so that you get the best quality finish you can with no pixellation. Pixellation is where the image looks grainy and distorted and happens when an image is supplied under the recommended dpi.
What are pixels?
Pixels refer to the tiny dots of colour that make up a digital image; think pointillism for the digital age. Thanks to really good design platforms like Photoshop, we can edit imagery pixel by pixel.
