Color Adjustment Tab This tab allows you to adjust the color balance by changing the settings of the Cyan, Magenta, Yellow, Brightness, Intensity, and Contrast options. Preview Shows the effect of color adjustment. The color and brightness change when each item is adjusted. You can check the color adjustment status easily by changing the preview image to one similar to the results to be printed with Sample Type. Note • The graphic is in monochrome when the Grayscale Printing check box is checked. Sample Type Selects a preview image displayed on the Color Adjustment tab. If necessary, select a preview image from Standard, Landscape, or Graphics, whichever is most similar to the print results. View Color Pattern Displays a pattern for checking color changes produced by color adjustment. If you want to display the preview image with a color pattern, check this check box. Cyan / Magenta / Yellow Adjusts the strengths of Cyan, Magenta, and Yellow. Moving the slider to the right makes a color stronger, and moving the slider to the left makes a color weaker. You can also directly enter a value linked to the slider. Enter a value in the range from -50 to 50. This adjustment changes the relative amount of ink of each color used, which alters the total color balance of the document. Use your application if you want to change the total color balance significantly. Use the printer driver only if you want to adjust the color balance slightly. Important • When Grayscale Printing is checked on the Main tab, Cyan, Magenta, and Yellow appear grayed out and are unavailable. Brightness Selects the brightness of your print. You cannot change the levels of pure white and black. However, the brightness of the colors between white and black can be changed. Intensity Adjusts the overall intensity of your print. Moving the slider to the right increases the intensity, and moving the slider to the left decreases the intensity. You can also directly enter a value linked to the slider. Enter a value in the range from -50 to 50. Contrast Adjusts the contrast between light and dark in the image to be printed. Moving the slider to the right increases the contrast, moving the slider to the left decreases the contrast. You can also directly enter a value linked to the slider. Enter a value in the range from -50 to 50. 488
