Photoshop in Focus

To get a firsthand look at how halftone dots work together, follow these steps:

1.
In Photoshop, use the File, New command. Create a new CMYK document, 800×600 pixels, filled with white, resolution 72 ppi.

2.
Select the Gradient tool from the Toolbox.

3.
In the Options Bar, open the Gradient palette by clicking on the arrow to the right of the gradient sample. Select the Spectrum gradient.

4.
Drag a linear gradient to fill the new document with color.

5.
Filter, Pixilate, Color Halftone opens the Color Halftone dialog box. Click the Default button, then the OK button.

6.
Use the Navigator palette to zoom to 400%. Use the Hand tool to drag the image around, looking at the pattern of dots.

7.
In the Channels palette, click on the Cyan channel to make it the only active (and visible) channel. Drag around with the Hand tool to see the size of the dots in various areas.

8.
Inspect the other channels, one at a time.

9.
When finished, close the document without saving it.
