to process colors for printing; the document itself is unchanged. This option is useful for printing devices that don't
support overprinting and is available only if you choose Composite from the Color menu. If you intend to use a file
for separations on a RIP (raster image processor) or for final output, don't select this option.
Important: When printing to a printer that supports overprinting, make sure that this option is unselected, so the
printer's native overprinting capabilities are used.

About halftone screen frequency
In commercial printing, continuous tone is simulated by dots (called halftone dots) printed in rows (called lines or
line screens). Lines are printed at different angles to make the rows less noticeable. The Screening menu in the Output
section of the Print dialog box displays the recommended sets of line screens in lines per inch (lpi), and resolution
in dots per inch (dpi), based on the currently selected PPD. As you select inks in the ink list, the values in the
Frequency and Angle boxes change, showing you the halftone screen frequency and angle for that ink.
A high line-screen ruling (for example, 150 lpi) spaces the dots closely together to create a finely rendered image on
the press; a low line-screen ruling (60 lpi to 85 lpi) spaces the dots farther apart to create a coarser image. The size of
the dots is also determined by the line screen. A high line-screen ruling uses small dots; a low line-screen ruling uses
large dots. The most important factor in choosing a line-screen ruling is the type of printing press your job will use.
Ask your service provider how fine a line screen its press can hold, and make your choices accordingly.
