What resolution should my print files be?
For standard print applications we require files at 300dpi (dots per inch) at 100% size. For large format print (anything greater than A2) files should be 300dpi at 25% size. On web based work it’s 72dpi at 100% size. Printers refer to resolution in dpi, or dots-per-inch. This is exactly as it is stated, the minimum number of dots per inch that your artwork can contain. We require artwork exactly at 300 dots per inch. Any lower and your quality will suffer. Any higher and one increases processing time unnecessarily. It’s also worth noting that resolution cannot be added at a later date.
