Printing color separations
When you send color work to a service bureau or printing shop, either you or the service bureau 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.”
Corel also supports PANTONE Hexachrome, a type of printing process that increases the range of printable colors.Talk to your service bureau about whether you should use PANTONE Hexachrome color.
When setting halftone screens to print color separations, we recommend that you use 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 service bureau uses. Before customizing a halftone screen, consult the service bureau 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.”

Changing the spot colors to process colors does not affect the original CorelDRAW file; it affects the way colors are sent to the printer.

You can set the screen frequency, screen angle, and overprint options for spot colors as well as process colors. For example, if you have a fountain fill made up of two spot colors, you can set one to print at 45 degrees and the other at 90 degrees.
