Chapter 5: Painting And Image Editing
To create a Duotone image:
1. Select paint object and choose Grayscale from the Image Mode menu to convert to Grayscale
mode.
You can also select image modes by choosing Image | Mode.
2. Click OK when Canvas prompts to discard color information. Then, choose Duotone from the
Image Mode menu.
3. Choose Monotone, Duotone, Tritone, or Quadtone from the Type menu in the Duotone Options
dialog box. Depending on the Type setting, the Ink 1, Ink 2, Ink 3, and Ink 4 Curve boxes,
color menus, and text boxes become available.
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 separations than necessary.
4. Choose ink colors by clicking the color palette icons and selecting colors in the palettes. You
must have already added the desired colors to the Presets palette for them to be available in
the pop-up palette.
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.
Specify ink colors in descending order of lightness value; i.e., darker color inks should
appear at the top, and lighter color inks should appear at the bottom of the dialog box.
Assign only solid spot colors or individual process colors for duotones. If you assign a
color ink made from CMYK components, Canvas treats it like a spot color and prints only
one plate for the color when you output color separations.
5. 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.
6. Click OK to apply the Duotone Options dialog box settings.
