Printing color separations
When you send color work to a print service provider or printing shop, either you or the print service provider must create color separations.
Color separations are necessary because a typical printing press applies only one color of ink at a time to a sheet of paper. You can specify
the color separations to print, including the order in which they print.
Printing presses produce color using either process color or spot color, or both. You can convert the spot colors to process colors at printing
time. For more information on spot and process colors, see “Choosing colors” on page 286.
When setting halftone screens to print color separations, we recommend that you use the default settings; otherwise, screens can be
improperly set and result in undesirable moiré patterns and poor color reproduction. However, if you are using an imagesetter, the screen
technology should be set to match the type of imagesetter the print service provider uses. Before customizing a halftone screen, consult the
print service provider to determine the correct setting.
If you have overprinted areas, you can choose how you want those areas to print. For more information about overprinting, see “Working
with color trapping and overprinting” on page 588.
