  • Page 35 Many printing methods cannot use all of the information stored in a high-resolution scan, so in these cases part of the information is wasted. For example, the file size of the image on page 3-8 is only 40K because it was scanned in gray scale at 75 dpi. Scanning the same image at 300 dpi in gray scale would require a file size of 660K, and 24-bit color at 300 dpi would require 1900K (nearly 2 megabytes).

  • Page 36: Size Or Scale

    2. Multiply the lines per inch by two to find the best scanning resolution. For example, for 133 lines per inch (a common resolution for magazines and books), scan your image at 266 dpi (2 x 133 = 266). Tip: For even smaller file sizes, try scanning at about 1.5 times the lines per inch.

  • Page 37: Ti Halftoning And Dropout

    For nearly all uses, none is the best setting for these. In case you have special needs that require halftoning at the time of scanning, see the Appendix for technical information on halftoning, dithering, and dropout on the ES-8OOC. The minus numbers lighten the image, the plus numbers darken the image.

  • Page 38: Judging Image Quality

    Judging image Quality When you look at your monitor to evaluate a scanned image, remember that the image will look different when it is printed. A monitor is a comparatively low-resolution device; some images that look good on a monitor do not look as good when printed and vice versa.

  • Page 39: Video Cards

    Video cards A video card that is sufficient for text may not be good enough for displaying graphic images, especially in color. If all your scanned images look coarse on your monitor, you may want to upgrade your video card. Monitors The resolution of your monitor, of course, also affects the quality of the image you see.

  • Page 66: Scanner Settings

    The data produced by the scanner needs to be reproduced to be seen as an image. This is done, for example, by displaying the image data on a computer screen or printing it on a printer. The same image data can appear different depending on how it is reproduced.
  • Page 67 Resolution The output resolution determines how many pixels, or dots, are used for scanning and reproducing an image. Resolution is measured in units of dpi (dots per inch). Some software uses the term pixels per inch (ppi). As the resolution value increases, the image is read and reproduced in finer detail.

  • Page 68: Data Format

    To enlarge or reduce the image size, use the scanner’s size function through your software. In your application software, perform only fine adjustments. Avoid changing the image size in your application especially if the image is scanned using halftoning, because the image quality deteriorates. The default size value is 100%.

  • Page 70 To reproduce an image of more than 2 bits/pixel/color, however, the output device should also be capable of producing the same tones. Many displays and printers cannot deal with this and are limited to monochrome without gradations, or to 8 or 16 colors. The data format chosen also affects the amount of data necessary for scanning and storing an image.

  • Page 71: Color Mode

    Color mode The color mode specifies color reading or monochrome reading. In color reading, you can choose either page sequence reading or line sequence reading. In monochrome reading, a dropout color can be specified (green, red, or blue). Color page sequence reading The scanner scans the document three times for green, red,...

  • Page 72: Halftoning Mode

    Halftoning mode Halftoning is a process of changing an image to a pattern of dots. This is required because a printing press produces images in a different way than photography does. Photographs have an almost infinite number of tones, with an almost infinite number of colors for color photographs, but printing uses only individual single-color dots.
  • Page 73 You can select from three types of halftoning, as well as enable or disable the halftoning process itself. When halftoning is disabled, the tones that the data can represent are determined by the data format. Halftoning is not available when 3 bits/pixel/color or more are selected as the data format, since halftoning is not necessary for such data.
  • Page 74 Halftoning mode B Halftoning mode A Halftoning mode C None Halftone is expressed in 4 by 4 bayer dither pattern. Halftone is expressed in 4 by 4 spiral pattern.

  • Page 76 Gamma correction This function adjusts the light intensity ratio between the original image and the output data. When the image is reproduced on certain types of output devices, the tones of the image will be closer to those of the original. The term “gamma” shows the ratio, as shown below.

  • Page 77: Color Correction

    This setting is suited for analog-input CRT displays which can display an image with multiple levels of tones of more than 1 bit/pixel/color (r = 2.2). This is usually the best setting. This setting is suitable for high-density printers, such as 24-dot printers and some page printers.
  • Page 78 This function processes the image data so that the data will be most suited for the characteristics of the color output device used. For example, CRT displays use the additive primary colors-green, red and blue--to produce other colors. On the other hand, printers use subtractive primary colors-magenta, cyan and yellow (and often additional black to give more definition), and colors can differ slightly depending on the...
