International Standards and Conformity Assessment for all electrical, electronic and related technologies
Examples of colour resolution and everyday objects
- Computer monitors use between 72 and 96 ppi.
- The industry standard for printing newspapers is 85 lpi.
- Flatbed scanners pick up information from a source such as a photograph at 300 to 1 200 spi, although a computing technique known as interpolation leads higher resolutions.
- Ink-jet and laser printers provide output of between 150 and 4800 dpi, although dots may overlap.
- Magazines emerging from an offset printer use between 120 and 150 lpi, while art magazines and books are printed at between 150 and 300 lpi or higher.
Note: photographic negatives and photographic prints do not use these measures.
