For the best results all images should be scanned at a high enough resolution to produce 75dpi when printed at full size. You need to calculate the resolution depending on the size of the original (the item your scanning) and what size you intend to reproduce it.
Image resolution - Scanning formula
| Size of Original |
250mm high |
| Intended size of reproduction |
1000mm high |

Rendered graphics such as Photoshop documents, or the .jpg, .tif or .eps files created from them should also be created to produce 75dpi at full size so again depending on what scale you are creating your artwork you need to calculate what resolution you should save your artwork at.
