Printer resolution

While digital cameras make up a digital image from millions of tiny pixels, printers represent a printed image from thousands of mini dots. This is one of the most important factors that you should keep a close eye on when you enter the printer market. Resolution plays an important role in the quality of your final printouts.

Printer resolution is measured by dots in a one-inch line. It shows how many individual points can be drawn in one inch .A printer can print a certain number of dots per inch horizontally and vertically. The higher its number, the better the final print quality will be. The 300 dpi printing resolution is considered adequate for most office text documents but many todays inkjet printers now offer up to 4800 x 1200 interpolated resolutions, allowing you to print impressive, more detailed pictures and quality documents.

  Many people get confused with dots per inch because some printers list different dpi figures for color, black&white or vertical and horizontal dimensions.

For example, a 600-dpi printer can print 360,000 (600 x 600) dots on one square inch of segment, which means that each dot is 1/600th of an inch in size. A 300 dpi printer means that each dot is 1/300th of an inch in size. If horizontal and vertical resolutions were different, generally both would be displayed (i.e., 4800 x 1200 dpi). Some printers (Lasers) let you print photo-realistic images on plain paper at 720x720dpi and at 1440x720dpi on specialty papers designed for photographic output.

High-end ink-jet printers may have resolutions of up to 4,800 x 1,200 dots per inch, but printers with resolution of 2,400 by 1,200dpi should be satisfactory. Youre not likely to detect any distinction in quality with general print jobs unless you go above 600 x 600 dpi resolution.

Six- and seven-color inkjets can provide better-looking prints than four-color inkjet printers can. 

For multifunction machines, which include scanner you should check the specifications about scanner resolution too.

Dont be fooled with statements of4800 x 1200 dpi enhanced or optimized (DPI) resolution for certain printers! The printers enhanced DPI resolution specifies the resolution that the printer is capable of reaching through interpolation. This is achieved through software algorithms (computer instructions in the program), which create the illusion of more grays than the printer can output. The printers physical or true resolution is its optical DPI. The higher the number of the optical DPI, the better the image quality can be.

With inkjet models, the size and precise position of the ink droplets on the page are also an important factor (if not more important than resolution) in achieving the best quality. Top photo quality is greatly dependent on a printers aptitude to lay down ink in accurate patterns and alignments. The size of an ink droplet is measured in picolitre, where the size of one picolitre is one trillionth of a liter, 100 micrometers or less in diameter.

This is about one millionth of an average sized raindrop. These ink drops are so small that you cant see them with the naked eye. The smaller the ink drop and higher the resolution, the finer detailed the printed photograph and richer its colors can be. So dont be surprised if some 300 dpi printers will produce output that looks better than images output at 1440 dpi.

Newer inkjet printers use two picolitre sized ink droplets but older models work only with more than 20 picolitre sized drops. Some newer printer models can employ variable dot technologies on the same image (under one hood). It means that the printer can decide where to place small drops and where the larger drops would be appropriate or needed.

You might noticed, after printing out your Las Vegas trip photos, that the colors looked different on your computer screen than in your print. That color difference is caused by the different color models used to reproduce colors in the two media. In print, colors are usually reproduced with a combination of four inks: Cyan, Magenta, Yellow and black. (CMYK) (K stands for the black printing ink to avoid confusion with B for blue). On screen, colors are reproduced with a combination of Red, Green and Blue lights. ( RGB).

To correct this problem, color management is also somewhat an important aspect. Color management simply means ensuring how colors from your computer screen will turn out on prints. Color management software intended to help render color more consistently and accurately in order to provide more idealistic printouts.

With coated papers that were designed specifically for your printer, you will be able to achieve better results.
