Item Description Choosing a resolution Scale Output resolution Scale (the output size relative to the size of the original) can be set by direct entry or using the Scale slider. Output resolution can be entered in this text box or set to match a particular output device by selecting the device from the output resolution menu. The units for resolution can be chosen from the menu to the right of the text box. • Inkjet printer Most inkjet printers require three or four dots of different colors to reproduce a single pixel (simulated halftone). The target resolution for an inkjet printer (in pixels per inch, or ppi), is therefore less than the printer's catalogue resolution (in dots per inch, or dpi). In general, resolutions of 180-240 ppi will produce acceptable results on printers with catalogue resolutions of 360, 720 or 1,440 dpi. (Note that although the terms used differ, both pixels and dots refer to the individual elements used to make up a picture-pixels in the case of monitors, dots in the case of printers.) • Dye-sublimation printer Printers that use photographic or dye-sublimation processes reproduce each pixel with a single dot (continuous halftone). The target resolution for these devices is therefore the same as the printer resolution. • Commercial printing Commercial printing processes typically use from 150 to 300 Adding resolution menu options (Macintosh only) lines per inch (lpi). As a rule of thumb, resolution for output on a commercial printer (in ppi) should be about twice the In the Macintosh version of Nikon Scan, options can be added number of lines per inch. to the resolution menu by selecting Add Resolution... from the output resolution menu and entering a name and resolu- • Monitor tion.
