In computers, dots per inch (dpi) is a measure of the sharpness (that is, the density of illuminated points) on a display screen. The dot pitch determines the absolute limit of the possible dots per inch. However, the displayed resolution of pixels (picture elements) that is set up for the display is usually not as fine as the dot pitch.

DPI stands for dots per inch, or the number of dots of ink that fill a linear inch of surface. DPI is used to measure printing resolution -- the higher the dots per inch, the better the resolution and the better the image quality. For example, if an image has a resolution of 300dpi, it means that a square inch of solid color will be filled with about 90,000 (300X300) dots of ink. (Return to Top)

By default, we scan pictures at 72 dpi since this setting seems to produce images of high quality without making the size of the files overly large. Please not that if you order your photos to be outputed to CD-ROM then 200 dpi scans are going to be included free of charge. If you want to scan your pictures at a higher dpi setting, please contact us and we will try to accomadate you.

let the XFree86 X server calculate the DPI value based on the DisplaySize parameter in its configuration file, XF86Config-4. See the XF86Config-4(5x) manual page for details. The first method is recommended if you already know the DPI value of your monitor and wish to always run it at the same resolution; the second method is the more flexible way, but only available for the XFree86 X server. In each of the files above, remove the -dpi word and the following number.

We advise that you contact your lab to confirm their output preferences or refer to your ink-jet manual.

DOTS stands for directly observed treatment short course, the curative treatment for tuberculosis. It is the name for a comprehensive strategy which primary health services around the world are using to detect and cure TB patients. It combines five elements: ii) Microscopy services to detect the infectious cases among those people attending health care facilities with symptoms of pulmonary tuberculosis, most importantly cough of 3 weeks duration or more.

Before you start uploading your photographs or graphics, it is imperative that you prepare them for the Internet. This process of preparation is called optimization. Graphics that are not optimized greatly increases the time it takes to load pages on the Internet. You may have been on a few of those sites. Most of the time, we simply move onto another site without waiting for the page to come up.

More often than not, customers asking this don't realize how many details in a photo will either be lost or result in parts too small to handle. Photos with high Dots Per Inch (DPI) are more likely to have this problem than lower resolution photos. Web quality 72 DPI produce vary acceptable results. As DPI goes above 100 the quality of the result does not usually improve much.

A pixel is a minute circular point of light about 10 or 12 thousandths of an inch in diameter (sometimes stated as 10 or 12 'mils') created on a monitor screen. A dot is a sample taken by a scanner for representation in a raster image. A 300 dots per inch (dpi) scan takes snapshots of dots which are about 3 mils across (3,33333....mils to be exact).

I make all my own graphics myself. (I use Adobe Photoshop 7.0, in case anyone was wondering.) I do not use graphics factories or pre-made layouts offered in webmaster shops.

DPI isn't as important as you might think. It's the effect DPI has on part size that you need to understand. If you provide a 50 DPI drawing then each dot represents .020 inches (our minimum). Higher resolutions produce higher quality output such as smoother curves up to a point (about 200 DPI). At 400 DPI, any part less than 8 dots wide in any direction will be too small or fragile to handle.

The resolution of printed text and images is measured in dots per inch, or DPI. The print resolution for a piece can range from 300 DPI to 1200 DPI, and sometimes more, depending on the level of detail required.
