2   In the Duotone Options dialog box, choose Monotone, Duo- tone, Tritone, or Quadtone in the Type pop-up menu. Depending on the Type setting, the Ink 1, Ink 2, Ink 3, and Ink 4 Curve boxes, color pop-up menus, and text boxes become available. 3   Choose ink colors by pressing the color palette icons and selecting colors in the pop-up palettes. Note: You must have already added the desired colors to the preset colors on the Color tab in the Inks palette for them to be available in the pop-up pal- ette. •   For a monotone image, choose a single color in the Ink 1 area. For a traditional duotone, leave “Process Black” as Ink 1, and choose a second color in the Ink 2 area. For tritones and quadtones, choose additional colors for Ink 3 and Ink 4. •   Canvas puts the name of the selected ink in the text box. •   To use process colors, type the appropriate name (“Process Cyan,” “Process Black,” “Process Magenta,” or “Process Yellow,”) so colors appear on the correct plates. If you leave the text box blank, Canvas prompts you to enter a name for the ink. •   You should specify ink colors in descending order of light- ness value. In other words, darker color inks should appear at the top, and lighter color inks should appear at the bottom of the dialog box. •   You should assign only solid spot colors (PANTONE inks) or individual process colors for duotones. If you assign a color ink made from CMYK components (including a Tru- Match color), Canvas treats it like a spot color and prints only one plate for the color when you output color separa- tions. 4 If necessary, click the curve boxes to adjust curves for each ink color. In the Duotone Curves dialog box, drag the curve to adjust it, or enter values in the text boxes to map input values to the desired output values, and then click OK. 5 Click OK to apply the Duotone Options dialog box settings. Tip If you plan to export a duotone image to another graphics or page layout program, be sure the color names exactly match the color names in the other application. Otherwise, you might produce more color sep- arations than necessary.
