Art Print Choose Art Print when scanning images from very high quality art prints that show only very fine dots. Color Match This is an effective tool for ensuring that the colors captured by the scanner more accurately reflect the actual colors of the original image. Without color matching, the scanner captures a wider range of colors but these colors may not accurately match the true colors of the original image, making the scan appear different from the original. Color Balance This tool balances the lightest and darkest areas of an image so that they are evenly distributed. Output Scaling Output scaling allows you to enlarge/shrink the size of the final output image. Adjust the scaling by using the slide bar or typing the desired setting in the Output Scaling box. For example, setting the Output Scaling to 200% will double the amount of pixels contained in the image. Width and Height The Width and Height values show the dimensions of the image area inside the Crop Frame. You can change the measurement unit to centimeters or inches. Image Size Image Size displays the amount of disk space needed to display or save the image outlined by the Crop Frame. The Image Size information is automatically updated anytime you change any of the scan settings or resize the Crop Frame. Without Color Balance With Color Balance 14 The Enhance Tab The Enhance tab contains preprocessing controls that can be applied to the image before making the final scan. To access the Enhance tab, click Enhance. The Enhance tab contains two picture thumbnails (Original and Sample) of the preview image, several control settings, and a histogram of the image. Alterations made to the enhance settings appear in the sample thumbnail. The image that appears in the thumbnails will automatically be replaced with the Preview image. If you wish to see the effects of your changes in the Preview Window, click on the Preview button. Channel Selector Channel refers to the red, green, and blue colors that make up a color image. You can choose to change the channels individually or choose Master to change all channels equally and simultaneously. An image in Gray Mode has one channel. Brightness Control Using 255 steps, this tool allows you to adjust the overall amount of light in the image. A value of ­127 will make the image appear very dark, whereas, a value of +127 will make the image appear very bright. Thumbnails Brightness ­50 Brightness 0 Brightness 50 15 Contrast Control Using 255 steps, this tool controls the disparity in tone between the dark and light areas of an image. Positive values create greater differences between dark and light areas of the image, whereas, negative values create greater similarities between the dark and light areas of the image. Contrast ­50 Contrast 0 Contrast 50 Eyedroppers Preview Button Click the Preview button to see any changes made to the image. The changes will appear in the Preview window. Level You can easily use the level slider to adjust an image's contrast and brightness. You can drag the little white triangle to control the amount of hightlights, and the black triangle to the shadows, if you haven't set the two values using the eyedroppers. The gray triangle in the middle controls the image's midtone. After the highlight and shadow values are determined, use the gray triangle to roughly control an image's contrast. You can control each channel's levels if you scan in RGB. Eyedropper tools Eyedroppers are used to identify an image's hightlights and shadows. Click on the darkest area that still contains detail with the black eyedropper to set the shadow value. Any darker parts will be regarded as black. And then the lightest area with the white eyedropper to set the hightlight. This is the first step to control an image's overall tonal range. 16 Curve If your original is too dark or too light, you lose vital detail after scanning. You can fix this problem by using curves. The curve function is applicable to grayscale and 24/48-bit color images. Simply put, if you knew how to use Adobe® Photoshop® or any other equivalent softwares' curve function, you can safely skip this section. properly, you can energize a dull image using curves without sacrificing the overall image quality. To write a curve, simply place an anchor on the diagonal line and adjust its position. Add more anchors if you have to write a more complex curve. You can also remove anchors. To emphasize shadow, raise the anchor; to emphasize highlight, lower the anchor; to emphasize midtone, write an S-shaped curve; to decrease contrast, write an inverted Scurve. Experts apply curves to individual channels to color-correct an image. Usually this is done to a CMYK image to be printed. add/remove anchors Applying a curve to an image is to enhance favored brightness ranges at cost of others, like enhancing the shadow at cost of the highlight and midtone. If done 17 Hue/Saturation If you knew HSB colorspace, you can also skip this section. In plain English, hue roughly means color: red, yellow, green, is static and the lower one movable. Slide the latter, and you will see the image shift its overall coloring. This function mostly affects loud colors, less on mute colors. It does not change black, whte and gray. The Saturation Slider lets you to adjust an image's color purity. Slide it to the left and the image becomes dull, like a black and white photo. Slide it to the right and the image becomes more colorful. These two functions are disabled when scanning in grayscale or 48-bit color. blue, purple; and saturation means a color's purity. When a maple leaf turns red, it changes hue. If you place a bright blue cardboard outdoors, its color will fade, it will be less and less saturated. The Hue Slider is composed of two color bars. The upper one 18 The Filters Tab The Filters tab contains special effect controls that allow you to alter the image before making your final scan. To access the Filters tab, click Filters. None No filter is applied if None (default setting) is selected. Blur The Blur filter smoothes the image by lightening the pixels that are in sharp contrast to their neighboring pixels. The amount of blur applied is controlled with the plus and minus buttons. Sharpen The Sharpen filter enhances the detail in blurry images by improving the focus and increasing the contrast in the image. The amount of sharpness applied is controlled with the plus and minus buttons. The Filters tab also contains two thumbnails of the previewed image. Any filter you choose will immediately show its effect in the sample thumbnail. 19 Invert The Invert filter transforms an image to its negative by converting all color values to their opposites: whites become black, blues become yellow, etc. Emboss The Emboss filter makes the elements in an image appear raised or sunken by reducing the color within the image and tracing its edges with black. Flip The Flip filter creates a mirror image of the original by flipping the image horizontally. About Tab The About tab contains the current driver version number, information about the interface device, and the copyright notice. To access the About tab, click About. Unsharp Mask The Unsharp Mask filter detects sharp edges and color boundaries and then emphasizes them. 20 Using Batch Scan Batch scanning is an easy way to multi-scan any part of your document using a variety of scan settings (Certain application programs do not support this function). Using Batch Scan you can specify up to 10 scan regions or scan a single region several times using different scan modes, resolutions, filters, and more. Batch Scan Controls Create Batch Scan: allows the user to create a new batch scan. Duplicate Batch Scan: duplicates the selected batch scan settings. Delete Batch Scan: deletes a batch scan. Exit Batch Scan: exits the batch scan box. Batch Ahead/Back: These arrows allow you to scroll through your batch job list. The Batch Box contains the thumbnail image, DPI, scan mode and image size of each batch scan. The batch number (e.g., 1/3, number 1 out of three) is always displayed at the top of the batch box along with the Batch Scan Status. 21 To Perform a Batch Scan 1. Click on the Batch Scan button. The Batch Scan dialog box appears. 2. In the TWAIN dialog box, set the desired scan mode and resolution for the current scan region. 3. Repeat steps 2 if you wish to create additional scan regions. NOTE: Using the Batch Scan arrows allows you to view different batch jobs. 4. Click Scan. The scanner will begin to scan the batch jobs one after the other. NOTE: You can assign different scan sizes (A4, A5 or custom) to each image separately. 22 Appendices Appendix A: Scanning Tips The following tables provide helpful information you can use when setting the scan mode and/or resolution.

The computer fails to recognize the scanner. Check to ensure the scanner is correctly connected to the computer. Power off your computer and the scanner, and reconnect them by carefully following our hardware installation instructions. The scan command is not executed. The scanner cable may be connected loosely. Check to ensure the scanner is correctly connected to the computer. Why do my images look blotchy or blurry? If your scans are looking bad on screen, but printing out satisfactorily, it could be your video driver that is causing the problem. Try changing the resolution and color settings in the "Display" portion of your Windows® control panel (after first making sure that you have the proper driver disks to restore your system to the original settings). You should be using a driver that provides 16+million colors, and a resolution of at least 800 x 600. 4. What resolution should I scan at? a. You should scan at the resolution of your output device. b. If you plan to display your scans on a computer monitor (Internet), which has a resolution of 72DPI, we recommend scanning at 72 DPI. c. If your output device is an inkjet printer: · For color images, scan at 1/3 the allowable resolution of the printer. · For Gray Mode or Line Art images, scan at the full resolution of the printer. 5. The scanned picture is not clear. We recommend that you keep the scan window glass and the document cover clean. They should be cleaned on a regular basis. The cleaning steps are: a. Turn off the scanner and unplug the power cord. b. Open the document cover and use a cloth dampened with alcohol to clean the scan window glass and the cover separately. c. Use a lint-free dry cloth to dry the glass and cover. 2. 3.
