Encapsulated PostScript

---

Encapsulated PostScript (EPS) files are ASCII text files containing the scalable PostScript representation of a ChemDraw drawing that can be opened using other applications and platforms. There are two types: one containing text only, and one containing a graphic representation of the drawing. The latter are known as Postscript Mac. For text only files, programs that do not support the display of raw PostScript can only print, not view an image on screen.

Use EPS files to share ChemDraw drawings with desktop publishing applications such as Adobe PageMaker and QuarkXPress.

The "Options" dialog box allows you to select the resolution (in dpi) and color depth of the saved file The defaults are 300 dpi and Monochrome.

.

If you select a color option, all colors are saved in the EPS file except for the Background color. To save an EPS file with a colored background, create a large colored rectangular box using the Drawing Elements tool and choose Send to Back before saving the file. For more information, see "Drawing Boxes" and "Using Multi-Center Bonds". These options only affect embedded images. Objects created in ChemDraw always output at maximum resolution and in full color.

Resolution

Available resolutions range from 72 (computer monitor) to 1440 dpi (high resolution output). When choosing a resolution, keep in mind that the size of the file increases as the square of the resolution.

Color

You can select from the following color options:

• Monochrome-Forces all objects to black and white.
• Grayscale-Translates colors to shades of gray.
• 24-bit RGB -Stores colors using computer monitor style of color encoding.
• 32-bit CMYK-Uses printing press style of color encoding. Groups each color type sequentially. This provides better compression.
