[. . . ] t Halftone The Halftone option simulates the tonal range of an image with a precise pattern of lines and dots. This option is useful when scanning documents with many shades of gray. To set a black and white option: 1. In the Black & White Options list, select Threshold or Halftone. Adjusting the Preview Image for Final Scan Once an image has been previewed, you can adjust it, as necessary, for the final scan by changing its selection size, its output size, aspects of its orientation, or aspects of its tone. For information on adjusting the tone of the preview image, see the “Adjusting the Preview Image Tone” section. 6-12 Scanning Chapter 6 Clearing the Preview Area If the preview image does not serve your purpose, you can quickly remove it from the preview area and rescan the image. To remove the current preview image: On the toolbar, click Clear Preview. Adjusting the Preview Image View To make it easier to work with your preview image, you can change aspects of its display. Changing the View Size You can enlarge a preview image to better view its details. Each enlargement doubles the size of the image up to a maximum of 4 times the size of the original image. As you enlarged the image, you can just as easily reduce it. Each reduction decreases the size of the image by one-half. To enlarge, left-click the mouse pointer on the image. To reduce, right-click the mouse pointer on the image. Displaying Rulers To work precisely with a preview image, you can display rulers on the top and left borders of the preview area. The rulers display in inches or centimeters, depending on what you have set as the unit of measure on the Main tab. For example, you can create an alternate version of your company logo. Chapter 6 Scanning 6-15 To create a mirror image of the preview image: On the toolbar, click Mirror. Rotating an Image You can rotate an image 90° left or right within the preview area to change its orientation. When you rotate an image, the entire preview area, including the rulers, rotates. For example, if the preview area is in portrait orientation, it becomes landscape. To rotate a preview image: On the toolbar, click Rotate Left or Rotate Right. Scaling the Image Output Size You can scale the preview image to better fit your needs. For example, if you reduce by 50% the scale of an image that is 7 inches wide by 9 inches high, the output image will be 3. 5 inches wide by 4. 5 inches high. However, in scaling an image for the final scan, keep in mind that the values in the width and height text boxes remain the same. The new output size is displayed under Output Size. Adjusting the Tone of the Preview Image The tone of an image is its shading and combination of colors. Adjusting grayscale tones can enhance the contrast of a grayscale image. You can produce a wide range of visual effects in your preview image by adjusting the different settings on the Tone tab. (Please note that the Tone Tab is not available on the ES290 model) 6-16 Scanning Chapter 6 If you selected Black and White or Text Enhanced as the scan mode, the Tone tab is not available for selection. In these cases, you must adjust the tone of the image with the contrast/brightness settings on the ES290 tab.
