Encapsulated PostScript (EPS)
EPS files can contain text, vector graphics, and bitmaps and are intended to be included (encapsulated) in other documents. Unlike other PostScript files, which can contain multiple pages, an EPS file is always a single page.
EPS files usually contain a preview image (header) that lets you view the file content without the help of a PostScript interpreter. An EPS file without a preview image is displayed as a gray box in Corel applications.
You can import and export EPS files. You can import an EPS file as a group of editable objects as you would import any other PostScript (PS) file. You can also bring the file as encapsulated, placing the preview image in the drawing window. The preview image is linked to the file. It is recommended that you import an EPS file as encapsulated in the following situations:
•
You want text in the EPS file to be displayed with the original fonts, without any font substitutions.
•
You are working with a large EPS file, and you don’t want to slow down the application.
During the CorelDRAW Technical Suite installation, you have the option of installing Ghostscript, which is an application that interprets the PostScript file format. Ghostscript allows you to import PostScript Level 3 files. If you did not install Ghostscript when you first installed the product, you can do so now.
To import an encapsulated PostScript file
1
Click
File Import.
2
Locate the folder in which the file is stored.
3
Choose
PS, EPS, PRN - PostScript (*.ps; *.eps; *.prn) from the list box next to the
File name box.
6
In the
Import EPS dialog box, enable one of the following options:
•
Import as editable — brings in the file as a group of Corel DESIGNER objects that you can modify
•
Place as encapsulated PostScript — places the preview image in the drawing. You cannot modify specific parts of the file, but you can edit the file as a whole by applying transformations, such as sizing and rotation.
7
If you are importing the file as editable, enable one of the following text options:
•
Text — preserves text objects in the imported file so that you can edit the text
•
Curves — converts text to curves
Some restrictions apply when you modify EPS files imported as editable. For more information, see PostScript (PS or PRN) technical notes.
If the EPS file contains text converted to curves, the text in the imported file is not editable, even if you choose to import the text as text.
You can also drag an EPS file from Windows Explorer into the drawing window.
To export an encapsulated PostScript file
1
Click
File Export.
2
Locate the folder in which you want to save the file.
3
Choose
EPS - Encapsulated PostScript from the
Save as type list box.
4
Type a filename in the
File name list box.
6
In the
EPS export dialog box, adjust any of the settings.
To set general exporting options
1
In the EPS export dialog box, click the
General tab.
2
Perform one or more tasks from the following table.
|
|
Specify the color mode for exporting to eps
|
In the Color management area, choose an option from the Output colors as list box:
If you choose the Native option, all objects preserve the color mode in which they were created, for example RGB, CMYK, Grayscale, or spot.
|
|
In the Color management area, enable the Convert spot colors to check box, and select an option from the list box.
|
Choose a file format for previewing the PostScript image
|
In the Preview image area, choose one of the following options from the Type list box:
If you choose the TIFF format, choose a color mode and resolution.
|
Specify how to export text
|
Enable one of the following options in the Export text as area:
• Curves — lets you export text as curves
• Text — lets you export text as editable characters
If you want to include PostScript font information with your file, enable the Include fonts check box.
|
Choose a compatibility option
|
From the Compatibility list box, choose a PostScript level that is supported by the printer or the application with which you will be printing or displaying the file.
|
Objects are always output as CMYK. Bitmaps have the option of different color modes.
If you choose the 8-bit TIFF format for previewing images, you can make the background of the bitmap transparent by enabling the Transparent background check box in the Preview image area.
To set advanced exporting options
1
In the EPS export dialog box, click the
Advanced tab.
2
Perform one or more tasks from the following table.
|
|
Specify the author’s name
|
Type a name in the Author box.
|
|
In the Bitmap compression area, enable the Use JPEG compression check box. Move the JPEG quality slider to adjust the quality of the bitmaps.
|
|
In the Trapping area, enable any of the following options:
• Preserve document overprint settings — maintains current settings on objects
• Always overprint black — creates a color trap by causing any objects that contain at least 95 percent black to overprint any underlying objects
• Auto-spreading — creates a color trap by assigning an outline to an object that is the same color as its fill and having it overprint underlying objects
• Maximum — lets you specify the amount of spread that the Auto-spreading option assigns to an object
If you want to specify the minimum font size to which Auto-Spreading is applied, type a value in the Text above box.
If you want the outlines of all objects on the page to have the same width, enable the Fixed width check box.
|
|
In the Bounding box area, enable any of the following options:
• Objects — aligns the bounding box exactly to the objects in the file
• Page — aligns the bounding box to the page
• Bleed limit — lets you specify how far the bleed extends beyond the edge of the area to be printed
• Crop marks — lets you use crop marks as alignment aids when you trim the print output to its final size
• Floating point numbers — lets you use numbers with decimals
|
|
Enable the Maintain OPI links check box to use low-resolution images as placeholders for high-resolution images.
|
The Use JPEG compression check box remains disabled until you choose a PostScript level that supports this feature.

Encapsulated PostScript (EPS) technical notes
Importing an EPS file
•
If the encapsulated PostScript file was imported with the
Place as Encapsulated PostScript option, and if it contains a preview image (called a header), the preview image is imported and displayed. The EPS information remains attached to the header and is used when the image is printed to a PostScript printer.
•
The PostScript Interpreted filter converts the objects in the encapsulated PostScript file to native Corel DESIGNER objects on import.
•
When you import a file with large or complex gradient fills, you may generate a large number of objects.
Exporting an EPS file
•
On a PostScript printer, graphics exported to the encapsulated PostScript (EPS) format print from other programs exactly as they do from a Corel graphics programs.
•
You can save a header to the Tagged Image file format (TIFF) or Windows Metafile format (WMF) in
black and white, 4-bit
grayscale or color, or 8-bit grayscale or color. You can set the header
resolution between 1 and 300 dots per inch (
dpi); the default header resolution is 72 dpi. If the program importing the EPS file has a limitation on the image header size, you might receive an error message stating that the file is too large. To reduce file size, in the
EPS export dialog box, choose
Black and White from the
Mode box, and lower the header resolution before exporting the file. The setting determines only the resolution of the header and has no impact on the print quality of a drawing. Color headers are useful for viewing EPS files. If the program in which you are going to use the file does not support color headers, try exporting with a mono header instead. You can also export without a header.
•
Along with the graphic, exported EPS files contain a filename, program name, and date.
•
To save font information in an EPS file, enable the
Include fonts check box in the
Export text as area.
•
If you export text as curves,
text is converted to vector curves.
•
If a font used in the file is not available on the printer or has not been saved in the file, either the text is printed in Courier font or the drawing is not printed.
