But, if you have many reds, yellows, whites an flesh tones, a noticeable breakdown will occur. If for example, you scan an image of a green forest, you may have very little breakdown during the indexing process. Images that contain every color in the universe are harder to drop down to 256 colors because many colors may be lost. When choosing images for Internet presentation, choose images that have fewer color jumps. We have found Photoshop and Debabelizer do this type of conversion very well. It's not publishing quality, it's but good enough for class instruction and referencing. In most cases, a 72 dpi image is adequate on a PostScript printer (as long as the image is not enlarged). You would not see the additional dpi on screen, but it would be there when the printer needed it, creating the best possible printed image. If the printed image is important to you, knowing the printer's dpi and line screen are important factors for image dpi. The 300 dpi image, although enlarged, has no noticible breakdown because it is now 144 dpi and still higher than your screen display. It is now 36 dpi, less than your screen's 72dpi resolution.

You can see a breakdown of the image in the 72dpi enlargement. One was scanned at 300 dpi, the other was scanned at 72 dpi, both were enlarged by two. Anything less then 72 dpi will produce pixelization of your image and give that chunky bitmap look.īelow you will find two images. Anything over that is unnecessary for screen viewing (printing is another kettle of fish altogether). Remember that in most cases, the screen resolution is 72 dpi. If you continue the enlarging process, the image will become very blurry and the pixels will become very evident, creating an unpleasant image. If you double its size, the image will then become 144 dpi and so on. Also, you can not add valuable information if it wasn't there in the first place.įor example, suppose you want to enlarge a small, previously scanned image that is 300 dpi. Planning ahead will save you time and disk space, and unnecessarily large images are memory hogs. You may need to enlarge or reduce the image for your page. Know what size your image needs to be before you scan it. Any more is a waste because you can not view more then 72 dpi on the screen. When you are using images for desktop viewing, 72 dpi is the best way to go. The image size increases as the dpi increases. Many laser or deskjet printers print 300 dpi and more. Most desktop scanners can scan 300, 600, and 1,200 dpi. Compare the two.ĭPI is a way of describing how many pixels are displayed, scanned, or printed. Here is the same 300/24 image using the system palette instead of the images palette (adaptive in Photoshop). In some cases, you will hardly notice the change at all. In most cases this gives much more pleasing results.

The best programs (Photoshop & DeBabelizer are two that we use) will allow you to sample the image and create a 256 color palette using the image's millions of colors. Often this creates a very nasty looking image out of what was a very nice image. In most cases, it decides which colors to keep by looking at the system color palette and using those as a guide.

The software analyzes which colors should stay and which ones should go by dropping colors out of the original image's palette. The process takes your original scan of millions or thousands of colors and converts them to a 256 color palette. When changing an RGB image to Index color, you are doing two things: actually changing and removing the colors of the image map and color palette. The best of them allow many conversion options. There are numerous software packages available that convert RGB images to Index colors.
