Image Resolution

Resolution is a very important part of printing and image editing.  It is good practice to use the industry standards of image resolution to make sure you always provide a good enough file to the printer.  We have a variety of printers here at CC Imaging.  Depending on the size you wish to print, the resolution differs slightly.

If you are printing at A3 (11.75" x 16.5" / 297mm x 420mm) or lower you should set your image resolution to 300 dpi/ppi (dots/pixels per inch).  If you are printing above A3, you should set your image resolution to 245 dpi/ppi. 

As we don't know which piece of software you are using, we have provided steps according to Adobe Photoshop CS.
