Resolution is tied directly to the quality appearance of your image. Resolution is the measurement of dots per squares inch (dpi). There is a lot to process when covering this topic. This article will be for beginners and novice.
For general commercial printing, there are two common resolution requirements. 300 dpi for color and grayscale images and 1,000 dpi for black and white bitmap (mode) images. While many scanners, cameras and programs support higher resolutions and you would think the higher the resolution the better image quality, the science of printing is driven by rules of Lines Per Inch (lpi) and how technology handles processing of files.
Here's where it gets a bit sticky to understand. I'll tried to explain it has best I can while giving you some techno info.
Color and Grayscale Images.
The 300dpi resolution rule applies to color and grayscale images only.
Bitmapped Images.
In general bitmapped images should be saved at 1,000 dpi. If you have a black and white, bitmapped image, the resolution should be set to the resolution of the output device. With that said, most people do not know the resolution of the output device without talking to the print service provider. Generally, however, the accepted resolution is between 800 dpi and 1,200 dpi.
The reason behind this lays in the human eye. The human eye at 800dpi begins to process a perfect lines and curve. At 1,200 dpi, the eye cannot distinguish a higher quality.
Vector Images:
(Images created in applications such as Illustrator, CorelDraw, FreeHand, CanvasDraw)
Because of how technology works when it comes to printing, any image created within these programs are considered device independent and will print at the printers resolution thus providing excellent image quality.
Generally most print shops (as of 2008) will print anywhere from 200 to 300 lpi. Back in the 90s' it was 150 to 200 lpi.
To answer a popular question I get - If you import a color or grayscale image into a vector apllications, does it become a vector graphic - NO. It simply becomes a color or grayscale image placed within a vector file. The same rules above would still apply.
Resolution for other technologies ******************************
For web creation, the standard is 72 dpi.
For consumer level ink jet printing, generally 150 dpi prints fine. This is highly dependent on the printing device itself.
For posters and large banners, it is best to ask your print service provider. Generally I have heard resolutions ranging from 100 to 600 dpi.
For digital photos sent to Photo Processing centers, contact those centers.
Hope this helps. Richard Perez

What happens when a raster graphics is resized?
raster graphics cannot be resized without losing image quality
Find a High Resolution world map?
In order to find a high resolution world map, you should search for high resolution world map on an online search engine under "images." Most image websites will allow you to specify the resolution of the image.
What is canvas in computer graphics?
Canvas is the viewport or image you are working on.
What is definition of scaling in computer graphics?
In computer graphics, image scaling is the process of resizing a digital image. Scaling is a non-trivial process that involves a trade-off between efficiency, smoothness and sharpness. With bitmap graphics, as the size of an image is reduced or enlarged, the pixels which comprise the image become increasingly visible, making the image appear "soft" if pixels are averaged, or jagged if not. With vector graphics the trade-off may be in processing power for re-rendering the image, which may be noticeable as slow re-rendering with still graphics, or slower frame rate and frame skipping in computer animation.

What uses more memory bit-mapped graphics or vector graphics?
It depends on complexity of a drawn picture, but in most cases, vector graphics takes less space on a media: a bit-mapped image stores information about each pixel of an image, wille vector image stores only types of objects and parameters for further rendering.
How do you resize photo for printing?
As usual, Image > Image Size but pay attention on image resolution.

Laser printer with 300 resolution printing?
300 DPI is a very low resolutioe resolution rating. If this is the maximum resolution for the laser printer that you are looking at, do not buy it if you need sharp (or even acceptable quality) graphics. 300 DPI is the lowest common printing resolution, and dots are easily seen when looking at an image printed. Most laser printers, however have a 300 DPI setting, along with 600 and 1,200 DPI resolutions. The resolution of a laser printer does not matter if you plan on only printing black text, as resolution does not matter in this case.
What image criteria must be checked before printing?
file size, resolution, and colormode
Is it important to consider the resolution of an image in adobe photoshop?
Yes it is, depend of what You want to do with image. IF You want to print then resolution is very important, if You gonna post image on web site more important are pixel dimensions because on web images will be displayed with 72 ppi regardless of original image resolution.
What is resolution in computer graphics?
The resolution of an image in computer graphics refers to the pixel density of said image. For instance, older monitors used 800x600 often times. This means that for every 4 pixels in the horizontal direction, there are 3 in the vertical. This is where the aspect ratio comes from, which for an 800x600 resolution, is 4:3. The higher the value of the resolution, the more pixels there are per area of the image or screen, which means that there is more potential for fine detail, and on most systems means a crisper image.

Is image resolution important?
Image resolution is very much important. An image in a wrong circumstance with wrong resolution can be looked terrible. For web images, the resolution for a same size image should be 72 on the screen. A perfect pixel and right size are needed for a correct line-up. If the image resolution is very much high, it will break the page lay out. For printing purpose, image resolution should be 300 PPI so that it remains unbroken with a 'screen'. If you look a magazine photo under a magnifying glass, the above mentioned conditions can be understood. Low resolution image looks fuzzy. Black type and black panels are considered as solid areas in print. For this, image resolution should be higher than usual for avoiding broken text. For supplying flattened artwork, I complete my artwork at 600PPI but I try to produce PDF/ X artwork to overcome this situation. For that, an overdo of resolution is not hampered and a pin-sharped result can always be obtained.
What is meant that bitmap graphics are resolution dependent?
bitmap or raster images are in other words pixel images and every pixel image must have resolution, resolution is number of pixels per inch, cm
Will Scan resolution have a direct bearing on print resolution?
No, only on the quality. If you have a picture that is in low quality, perhaps because you scanned it that way, printing in high resolution won't be able to improve the image quality.
Used to measure printer resolution?
Abbreviated dpi. The number of dots that can be printed, side by side, along a line one inch long; a measure of the resolution of a printing device, printed image or image on an electronic display screen such that a greater number of dots per inch represents higher image quality.
What is the best image compressor for making image files smaller?
Depends for what the image is going to be used. If it's for a high resolution printing such as print ad in a magazine or poster TIFF format with LZW is preferred for quality purpose. JPEG format gives more options for compressing an image, especially for web usages or not for high quality printing purpose. Also it depends on the original image quality and resolution, if the quality of the original image is good, then JPEG will be a good option to use.
