Dots per inch DPI, or dpi1 is a measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch 2. Monitors do not have dots, but do have pixels the closely related concept for monitors and images is pixels per inch or PPI. Many resources, including the Android developer guide, use the terms DPI and PPI interchangeably. DPI measurement in printingeditDPI is used to describe the resolution number of dots per inch in a digital print and the printing resolution of a hard copy print dot gain, which is the increase in the size of the halftone dots during printing. This is caused by the spreading of ink on the surface of the media. Up to a point, printers with higher DPI produce clearer and more detailed output. A printer does not necessarily have a single DPI measurement it is dependent on print mode, which is usually influenced by driver settings. The range of DPI supported by a printer is most dependent on the print head technology it uses. A dot matrix printer, for example, applies ink via tiny rods striking an ink ribbon, and has a relatively low resolution, typically in the range of 6. DPI 4. 20 to 2. 80 m. An inkjet printer sprays ink through tiny nozzles, and is typically capable of 3. DPI. 2 A laser printer applies toner through a controlled electrostatic charge, and may be in the range of 6.

The DP measurement of a printer often needs to be considerably higher than the pixels per inch PPI measurement of a video display in order to produce similar quality output. This is due to the limited range of colors for each dot typically available on a printer. At each dot position, the simplest type of color printer can either print no dot, or print a dot consisting of a fixed volume of ink in each of four color channels typically CMYK with cyan, magenta, yellow and black ink or 2. Higher end inkjet printers can offer 5, 6 or 7 ink colors giving 3. Contrast this to a standard s. RGB monitor where each pixel produces 2. RGB. While some color printers can produce variable drop volumes at each dot position, and may use additional ink color channels, the number of colors is still typically less than on a monitor. Most printers must therefore produce additional colors through a halftone or dithering process, and rely on their base resolution being high enough to fool the human observers eye into perceiving a patch of a single smooth color. The exception to this rule is dye sublimation printers, which can apply a much more variable amount of dyeclose to or exceeding the number of the 2. These disadvantages mean that, despite their marked superiority in producing good photographic and non linear diagrammatic output, dye sublimation printers remain niche products, and devices using higher resolution, lower color depth, and dither patterns remain the norm. This dithered printing process could require a region of four to six dots measured across each side in order to faithfully reproduce the color in a single pixel. An image that is 1. Fittingly, 6. 00 dpi sometimes 7. This contrasts with the 3. A 1. 0 1. 0 pixel image on a computer display usually requires many more than 1. The whole blue pixels making up the sphere are reproduced by the printer using different overlaid combinations of cyan, magenta, and black ink, and the light aqua by cyan and yellow with some white ink free print pixels within the actual image pixel. When viewed at a more normal distance, the primary colored stippled dots appear to merge into a smoother, more richly colored image. DPI or PPI in digital image fileseditIn printing, DPI dots per inch refers to the output resolution of a printer or imagesetter, and PPI pixels per inch refers to the input resolution of a photograph or image. DPI refers to the physical dot density of an image when it is reproduced as a real physical entity, for example printed onto paper. A digitally stored image has no inherent physical dimensions, measured in inches or centimeters. Some digital file formats record a DPI value, or more commonly a PPI pixels per inch value, which is to be used when printing the image. This number lets the printer or software know the intended size of the image, or in the case of scanned images, the size of the original scanned object. For example, a bitmap image may measure 1,0. If it is labeled as 2. PPI, that is an instruction to the printer to print it at a size of 4 4 inches. Changing the PPI to 1. However, changing the PPI value would not change the size of the image in pixels which would still be 1,0. An image may also be resampled to change the number of pixels and therefore the size or resolution of the image, but this is quite different from simply setting a new PPI for the file. For vector images, there is no equivalent of resampling an image when it is resized, and there is no PPI in the file because it is resolution independent prints equally well at all sizes. However, there is still a target printing size. Some image formats, such as Photoshop format, can contain both bitmap and vector data in the same file. Adjusting the PPI in a Photoshop file will change the intended printing size of the bitmap portion of the data and also change the intended printing size of the vector data to match. This way the vector and bitmap data maintain a consistent size relationship when the target printing size is changed. Text stored as outline fonts in bitmap image formats is handled in the same way. Other formats, such as PDF, are primarily vector formats which can contain images, potentially at a mixture of resolutions. In these formats the target PPI of the bitmaps is adjusted to match when the target print size of the file is changed. This is the converse of how it works in a primarily bitmap format like Photoshop, but has exactly the same result of maintaining the relationship between the vector and bitmap portions of the data. Computer monitor DPI standardseditSince the 1. Microsoft Windows operating system has set the default display DPI to 9. PPI, while AppleMacintosh computers have used a default of 7. PPI. 3 These default specifications arose out of the problems rendering standard fonts in the early display systems of the 1. IBM based CGA, EGA, VGA and 8. Macintosh displays featured in the 1. K computer and its successors. The choice of 7. 2 PPI by Macintosh for their displays arose from the convenient fact that the official 7. Points are a physical unit of measure in typography, dating from the days of printing presses, where 1 point by the modern definition is 17. Thus, the 7. 2 pixels per inch seen on the display had exactly the same physical dimensions as the 7. As it is, the Macintosh 1. K featured a screen measuring 5. North American paper size in Europe, its 2. A4. B5 is 1. 76 millimeters x 2. A consequence of Apples decision was that the widely used 1. This is technically described as 1. PPEm. This made 1. Furthermore, there was the consideration that computer screens are typically viewed at a desk at a distance 3.
