  • Page 33: Determining Your Resolution

    4.2.2 DETERMINING YOUR RESOLUTION A good control of the resolution results a satisfactory detail of an image that scans. The resolution is measured by dots per inch(dpi). Normally, the greater the dpi number, the higher the resolution and the image file size. Be aware that the greater resolution takes more time, memory and disk space, therefore, up to a certain degree of dpi, the resolution will not visually be improved, on the contrary, it makes your files more unmanageable.
  • Page 34 Tips: 1. For your information, an A4 size color image scanned at 300 dpi at True Color mode consumes approximately 25 MB of disk space. A higher resolution (usually means over 600 dpi) is recommended only when you need to scan a small area at True Color mode.

  • Page 35: Selecting A Proper Image Type

    4.2.3 SELECTING A PROPER IMAGE TYPE Select image type through the mode from the scanner user interface for your own purpose. Please see Figure 4-4 as shown in below: Figure 4-4 Image Type Scanner Operation...
  • Page 36 Each image type is described as follows: Line art LineArt presents the image in black and white only and there are no intermediate shades of gray in between. That means each pixel of the image is 100% black or 100% white. LineArt is the best choice of image type if you want to scan text, pen or ink drawing.
  • Page 37 Halftone In addition to the black and white display, Halftone simulates grayscale by using different size of dots. Particularly when you view the image at a certain distance, it looks very closely like a gray image yet it consumes the least disk space. Halftone is the picture that we usually see in newspapers or magazines.
  • Page 38 Gray (1024 levels gray scale/Internally) A single-channel image consists of at least 256 levels of shades of gray in an image. A 10 bits scanner produces a Gray image with 1024 shades of gray between pure black and pure white. Gray is the best choice of image if you wish to scan a black and white photograph.
  • Page 39 True Color A 30-bit Color image consists of three 10-bit color channels. The red, green, and blue channels are mixed together to create a combination of one billion(2 ) colors which give a more true-to-life quality to the image. True Color is the best choice if you want to scan a color photo.
