Get Your Dots Right

In addition to providing accurate tints, a properly calibrated imagesetter helps avoid blown out highlight and clogged shadow dots in your halftone images. Accurate halftone screens become much more important as your shop moves from black-and-white work into duotones, tritones and process color, since PostScript imagesetters use the same halftone techniques to produce color separations as they do to produce grayscale output.
