Abstract

The EPSF Riders file is a file that can modify documents created in Adobe Illustrator. Although the user s guide and the notes in the EPSF Riders file recommend that the Riders file be edited only by experienced PostScript ™ language users, several code fragments included in the file can be easily modified to create commonly requested effects, such as modifying the flatness, line screen, and screen angles of documents. You can also use the Riders file to add a text line to the bottom of document pages. Riders file modifications are not visible in the preview of the document but appear in the printed copy if the Riders file is in the Plug-ins folder (for Adobe Illustrator version 5.0 and higher) or the application folder (for Adobe Illustrator 3.x).

Using the EPSF Riders File

Tech Note #4004 (12/15/93)Adobe Illustrator TM -- Macintosh ®

The EPSF Riders file is a file that can modify documents created in Adobe Illustrator. Although the user s guide and the notes in the EPSF Riders file recommend that the Riders file be edited only by experienced PostScript TM language users, several code fragments included in the file can be easily modified to create commonly requested effects, such as modifying the flatness, line screen, and screen angles of documents. You can also use the Riders file to add a text line to the bottom of document pages. Riders file modifications are not visible in the preview of the document but appear in the printed copy if the Riders file is in the Plug-ins folder (for Adobe Illustrator version 5.0 and higher) or the application folder (for Adobe Illustrator 3.x).

CREATING OR MODIFYING RIDERS FILES

You can create more than one Riders file to generate different effects for documents. In Adobe Illustrator 5.0, you can use the RidersMaker TM plug-in filter to create Riders files; in versions of Adobe Illustrator earlier than 5.0, you can use any text editor to create or edit a Riders file. Save each Riders file you create with a unique name; then rename the file Adobe Illustrator EPSF Riders, and drag it to the Plug-ins folder (for version 5.0) or the application folder (for earlier versions) when you want to use the file with a document.

Note: If the EPSF Riders file is not being used, it should be removed from the Plug-ins folder or the application folder because it can slow the program s performance. In addition, line screen frequency and angle settings contained in an active Riders file override those settings in Adobe Separator TM .

EDITING THE RIDERS FILE IN ADOBE ILLUSTRATOR 5.0 Adobe Illustrator 5.0 includes a third-party plug-in called RidersMaker, which automatically generates PostScript code for the Riders file.

To create a Riders file using RidersMaker:

1 Open the 3rd Party Utility folder in the Separator & Utilities folder, and locate the RidersMaker plug-in filter.

2 Drag the RidersMaker plug-in filter to the Plug-ins folder; then double-click the icon to start the Adobe Illustrator program. The RidersMaker plug-in filter is added to the Filters menu.

3 To create a customized Riders file, choose Riders/Make Custom Riders from the Filter menu. The Custom dialog box appears with the list of available Riders file options.

To enter a value for an option, make sure that the option is selected, click the Setup button next to the option, and then enter the value in the dialog box. See "Riders File Options" later in this technical note information on the options. 4 When you have sele...
