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 Choose colors.
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 Color trapping and overprinting.
To print color separations
You can change the order in which color separations print, by clicking Advanced in the Options area. In the separations list at the bottom of the dialog box, click in the Order column next to the color separation that you want to change. Chose a new order value from the list box.
If you want to print separations using a color profile that is different from the document color profile, you can click the Color tab and choose a color profile from the Color profile list box.
To convert spot colors to process colors
Changing the spot colors to process colors does not affect the original Corel DESIGNER file; it affects the way colors are sent to the printer.
To customize a halftone screen
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.
