Images and graphics may look good on screen, but not when printed. Pixelation can give a ‘blocky’ look. That’s why we’ve compiled our handy Resolution Guide, to make sure that your printed products look as good as they can!
The reason for a ‘pixelated’ look is that a screen will display a document at 72-100 dpi. Dpi (or ppi) stands for dots per inch or pixels per inch When printed, you will see 300dpi. Zoom in 400% to view a PDF and you will have an idea of the unwanted detail!
72dpi text on the left hand side will appear distorted when printed, while the 300dpi example will appear clear.
This problem can be solved by changing the options given when saving to a pdf or jpg image. The resolution options should always be set to a minimum of 300dpi. Compression options should be set to maximum.
An image made from dots is called a raster image. Another format, called vectors, will never distort at any size.
Incorrect Dpi is the main problem for resolution, but there can be other factors to consider.
Keep in mind the initial quality and size of the image you are going to use – any faults, blurs or distortions will only be magnified during the printing process, if the image is to printed in a larger scale than its original.
It’s also best to set up your artwork correctly, to ensure that none of your image is lost or pixelated in any way.
