You can select all ranges, or you can choose one or more midtone ranges. Page 49 All Midtones Advanced Scanning Modify Color Values There are two ways to adjust color values in this dialog box: Color wheel Click and drag to move the white point to a different color orientation on the wheel. The image's color balance will shift accordingly. Slide the color sliders back and forth between the complementary colors. Color slider With either of these methods, you can see the numerical values above the color wheel shift as you make the changes. Only active color ranges will be affected by these changes. Applying Scanning Filters Your EPSON Perfection 600 software can automatically adjust an image based on the type of original scanned. These automatic adjustments are called filters. Page 50 Advanced Scanning From the Filter drop-down list, choose one of the following: Sharpen The scanner software has a sophisticated sharpening feature that automatically sharpens an image (makes it less blurry) by increasing the contrast (distinction between dark and light tones) between adjacent pixels. This is the default filter and is useful primarily on photographs and grayscale images. Descreen When photographs and illustrations are printed in newspapers or magazines, they are "screened"--a process that turns images into tiny dots. (If you look at a photograph in a newspaper with a magnifying glass, you'll see that the image is actually composed of many small dots. ) If you are scanning an image that has been previously screened, you can sometimes get undesirable results, Page 51 Note: Filters are only available when you select a color or grayscale scan type. Note: Scanning runs slower when the Descreen filter is used because of the intensive computations required to process the image. Advanced Scanning such as losing resolution or sharpness. To counter the effect of the screen process and turn the dots back into a smoother image, set the filter option to Descreen. If you use the descreening filter, don't enlarge the image as this could cause a moiré effect--strange patterns that appear in an image due to the spacing between bands of dots in the image. You may need to sharpen the image after descreening, but you will need to do so in your graphics application. None Select this option if you don't want to use any filter. Changing Image Resolution Resolution refers to how many dots per inch (dpi) or dots per centimeter (dpcm) a device can print or scan. Page 52 Advanced Scanning The best resolution for a scanned image depends on the type of image you are scanning and your final output device. The following table shows the best scanning resolutions for the most common applications: Output device Inkjet printer Note: Resolution in professional printing is measured in lines per inch (lpi), rather than dots per inch (dpi). Recommended Resolution 240 dpi 150 dpi 72 dpi 250 dpi 300 dpi 150 dpi 170 dpi 225 dpi 600 dpi Monochrome laser printer Computer screen Four-color printing press with 150 lpi Four-color printing press with 175 lpi B&W printing press with 85 lpi B&W printing press with 100 lpi B&W printing press with 133 lpi Line art logo Optical Character Recognition (OCR) 300 dpi The higher a resolution you select, the larger the resulting image file. For example, an 8. 5 x 11 inch original scanned at 300 dpi can produce a 24 MB file. Page 53 Advanced Scanning The same original scanned at 72 dpi creates only a 1. 3 MB file. Large files take longer to process and print, so consider the practical limitations of your computer system and hard disk drive when selecting a resolution. To keep file size manageable, select the lowest possible resolution that gives acceptable quality. For Home or Office Output As a rule of thumb for any image except line art, use scanning resolutions that are approximately one third of your output resolution. For example, use a scanning resolution of up to 110 dpi with a 300 dpi laser printer, and up to 170 dpi with a 600 dpi laser printer. For inkjet printers, such as for a 1440 dpi EPSON Stylus® COLOR series printer, use a scanning resolution of up to 240 dpi. Page 54 Advanced Scanning For Professional Output For commercial printer output, multiply the lines per inch (lpi) that the press prints (your printer can provide you with this information) by 2 to determine your scanning resolution. For example, if the lpi is 150, try scanning at 300 dpi. (If the resulting file size is too large, multiply the lpi by 1. 5 x instead of 2 and try again. ) How To Change Image Resolution Note: Your Perfection 600 scanner software supports up to 2400 dpi scanning resolution, although you probably won't need resolution that high. To change the image resolution, move the resolution slider to the left to decrease resolution or right to increase resolution. Click to switch between dpi and dpcm The dpi display shifts as you do so.
