Chapter 22. PRINT > Producing duotones

Producing duotones

Only about 50 shades of an ink color can be printed from one plate, so print shops are sometimes asked to print a grayscale image using two or more plates instead of one, adding midtones or highlights to extend an image's tonal range. The additional plates can be gray or a color tint. You can convert an image to Duotone mode in Photoshop to create a duotone (two plates), tritone (three plates), or quadtone (four plates).

Threes and fours

Printing a tritone (three inks) or a quadtone (four inks) requires specifying the order in which the inks will print on press. You can use the Overprint Colors dialog box to adjust the on-screen representation of various ink printing orders, but these settings won't affect how the image actually prints. Ask your print shop for advice about printing.

Back to square one

The Duotone dialog box opens with the last-used settings. If you change the duotone Type and then want to restore the last-used settings, hold down Alt/Option and click Reset.
