The importance of resolution in your Elements work is paramount to printing files. 72-ppi images can be forgiving, and you can get many of your large files scrunched down to 72 ppi for websites and slide shows. With output to printing devices, it’s another matter. There are many different printing output devices, and their resolution requirements vary.
For your own desktop printer, plan to print a variety of test images at different resolutions and on different papers. You can quickly determine the best file attributes by running tests. When you send files to service centers, ask the technicians what file attributes work best with their equipment.
| Output Device | Optimum | Acceptable Resolution |
|---|---|---|
| Desktop laser printers | 300 ppi | 200 ppi |
| Desktop color inkjet printers | 300 ppi | 180 ppi |
| Large-format inkjet printers | 150 ppi | 120 ppi |
| Professional photo lab printers | 300 ppi | 200 ppi |
| Desktop laser printers (black and white) | 170 ppi | 100 ppi |
| Magazine quality — offset press | 300 ppi | 225 ppi |
| Screen images (web, slide shows, video) | 72 ppi | 72 ppi |
| Tablet devices and smart phones | 150+ ppi | 150 ppi |
