    Selecting the Output Device Use the following procedures to select the output device (printer, etc.) for the scanned image. Select the device that corresponds best to your output device and use of the image. Operating Procedures Click the arrow on the [Output Device] section of the control panel and select a device from the pop-up menu.
  • Page 19: Setting The Resolution And Magnification

    Setting the Resolution and Magnification The magnification of an image can be changed before scanning to accommodate reproductions that are larger or smaller than the original. The settings can be changed in increments of 1%. 6"/15cm 4"/10cm Changing the magnification setting causes the resolution display on the control panel to change correspondingly.
  • Page 20 To Set the Magnification Factor Set the desired magnification factor on the control panel. Click here to return the magnification factor to 100%. Hint The Relationship Between Data Volume and Scanning Resolution The higher the magnification and scanning resolution settings, the greater the file size of scanned images.
  • Page 21: Setting The Scan Mode

    Setting the Scan Mode When an image is scanned, it is read as a collection of “dots.” The scan mode that is selected determines how each of these dots is represented in the output. The following four scan modes are available. Black and White Expresses images in two colors only: black or white.

  • Page 40: Tone Adjustment

    Tone Adjustment Use Tone Adjustment to enhance the brightness or color of the image in the preview area. Open the [Image] menu and select [Tone Adjustment], or click the [Tone Adjustment] button, to open the Tone Adjustment dialog so you can enhance the preview image. You can also click the [Auto Tone Adjustment] button so the histogram highlights and shadows are adjusted for you automatically to the optimum settings.
  • Page 41: Histogram Settings

    Histogram Settings The data comprising an image contains a variety of brightness settings ranging from shadows to highlights. These settings are represented in Plug-in Module CS-U by values ranging between 0 and 255. The difference in these values determines the image’s contrast. To show how much of the image data falls into each brightness setting, Plug-in Module CS-U contains a histogram feature that shows this data distribution clearly.
  • Page 42 How to Adjust Histograms To change the contrast in an image, the distribution of data between shadows and highlights can be adjusted by dragging the shadow and highlight marks at the bottom of the histogram. All of the data lying to the outside (left) of the shadow mark is changed to a zero value and all of the data lying to the outside (right) of the highlight mark is changed to a 255 value.
  • Page 43 The histogram settings can be adjusted for all channels (Master) or for individual channels (R, G, B). The selectors are displayed to the left of the histogram graph (Master, R, G, B). The Master selection is unavailable if Grayscale has been selected as the scan mode.
  • Page 44: Tone Curve Settings

    Tone Curve Settings You can edit the tone curve directly by changing the shape of the line on the graph. When you change the setting by manipulating the curve, you can perform fine adjustments in the brightness of only the shadows, only the highlights, or both the shadows and highlights.
  • Page 45 To Edit the Tone Curve In the Tone Adjustment dialog box, click the tone curve tab. Change the tone curve in any direction to adjust its shape. You can adjust the setting for each channel: R (red), G (green), B (blue) or M (master).
  • Page 46 The Relationship Between the Tone Curve and Image Brightness The Gamma values fall with a range of 0.01 to 10.00. A value of 1 appears as a straight line in the graph, and if the value is any value other than one, the line on the graph will appear curved.
  • Page 47: Brightness And Contrast Settings

    Brightness and Contrast Settings You can adjust the image with two slide bars, one for contrast and one for brightness. Use this method to adjust an image before scanning if it is slightly out of focus or too dark. Hint •...
  • Page 48 To Adjust the Brightness and Contrast In the Tone Adjustment dialog click the brightness/contrast tab. Adjust the brightness/contrast settings by dragging the slidebars, changing the value with the spinbox buttons, or entering the value directly into the entry box. To restore all the default settings, click this button. To restore the brightness/contrast default settings, click this button.
  • Page 49: Adjusting The Color Balance

    Adjusting the Color Balance You can enhance color matching by adjusting the color balance of one or all of the three primary colors: red, green and blue (RGB). Use this feature to adjust the color balance when you see an over-abundance of a color in a scanned image. Hint •...
  • Page 50: Gamma Value Settings

    Setting the screen display gamma value causes the scanner gamma value to be calibrated automatically as the inverse value. For example, if the screen display gamma value is set for 1.8, then the scanner gamma value is calibrated for 0.56 (the inverse of 1.8).
  • Page 51 To Change the Gamma Value Settings Click the gamma tab in the Tone Adjustment dialog. Click a pre-set value or the custom option. The Tone Adjustment settings can be saved in a file and reloaded for later use. To restore all the default settings, click this button. To restore the gamma default settings, click this button.
  • Page 52: Adjusting The Threshold Value

    Adjusting the Threshold Value When the scan mode is set to black and white, the image brightness can be adjusted. The threshold value setting determines whether a halftone will be expressed as a black or a white data point. The possible threshold values range between 0 and 255.
  • Page 53: Auto Tone Correction

    ColorSync: Automatically matches the color settings of the scanner, computer display and color printer. Select this mode when you wish to set the appropriate color profile to view the colors of the scanned image on the computer display as closely matched to the original image as possible.
  • Page 54: Unsharp Mask

    Unsharp Mask The Unsharp Mask function enhances the outlines of an image. When set to On, this function makes the image outlines appear sharper without changing the brightness, contrast or color balance, giving it a natural look. It is particularly useful for scanning images that are slightly out of focus.
  • Page 55: Descreen

    Descreen Select this option if you want Plug-in Module CS-U to conduct moiré reduction to improve the overall image quality. Moiré are dot patterns that interfere with processing images for professional use and are usually caused by poor dithering resulting from scanning images from newspapers, books, magazines, etc. Caution •...
  • Page 56: High-Speed Scan Mode

    High-speed Scan Mode This function is available when the image source is set to [Platen]. When a check mark is placed beside this option, scanning can be accomplished faster because the lamp output data (auto color adjustment data) from the first pass is used for subsequent passes.
  • Page 57: Saving/Recalling Settings

    Saving/Recalling Settings The scan mode, resolution and preference settings can be saved with a preview image to a settings file and recalled for future processing. The user may freely assign a name to the settings file. It is convenient to save frequently used settings in a file.
  • Page 58 S T E P To Recall a Settings File Open the [Setting File] menu and select [Load]. Select the folder where the file is stored and click the name of the file you want to load. Click the [Open] button. The file you selected opens and the settings stored in the file are enabled for the Tone Adjustment settings.
  • Page 59: Scanning Techniques

    Plug-in Module CS-U provides many choices of resolution. The resolution you choose should depend upon your output device, the intended purpose of the image, the type of image and your scanner. It is generally recommended that you scan at a higher resolution than required for output.
