IMPORTANT
Only image files that have been created or opened in a CMYK
format can be saved as DCS files by PhotoFlash. PhotoFlash can’t directly
convert RGB (red, green, blue) image files to a CMYK file format like DCS.
If the DCS menu item is dimmed in the Save As submenu, it means the image
file you’re attempting to convert is not in a CMYK format.
You can obtain Photoshop-compatible plug-in modules that allow you to
convert an image file to CMYK formats from within PhotoFlash. Such files
are usually used with the Export command in the File menu. Sometimes they
are used with the Save As command.
Because the DCS file format is a variation of the EPS file format, the settings
and controls that appear in the Save As DCS dialog box are the same as those
for EPS files. For more information about using these settings and controls,
see “EPS” earlier in this chapter.
Number of colors or grays supported by standard file formats
Some file formats limit the number of colors or shades of gray that images
saved in those formats can use. This table lists the number of colors or grays
that you can specify when converting image files to the standard file formats
supported by PhotoFlash.
