A device-independent PostScript file is ideal for composite prepress workflows, where the file will be trapped and
separated later in the production process, such as during imposition, trapping, or at the RIP (if the output device
supports in-RIP separations).
1 Choose File > Print.
2 In the Print dialog box, for Printer, choose PostScript File.
3 For PPD, choose Device Independent.
4 View or change existing print settings. InDesign uses the current page range when creating the PostScript file.
5 Click Save.
6 Specify a name and location, and click Save.
Create a device-dependent PostScript file using InDesign
Select PostScript File in the Printer menu, and select a PPD. A device-dependent PostScript file has the following
characteristics:
• It is 100% DSC-compliant, making it ideal for such post-processing tasks as trapping and imposition.
• It contains a description of everything in your document, including information about linked files, optimized
screen frequencies, resolution, and available media sizes tailored to the currently selected output device.
• All driver dependencies are removed.
• It can be composite or separated. All of the color output methods that InDesign supports are available. (In-RIP
separations are available if the PPD and output device support them.)
• It can be trapped by InDesign (either by using Application Built-In or Adobe In-RIP Trapping).
• It can only be printed to file (not directly to a device or application) from InDesign.
A device-dependent PostScript file is ideally suited to pre-separation or trapping workflows, where the file will be
trapped using automatic or Adobe In-RIP Trapping features within InDesign.
1 Choose File > Print.
2 In the Print dialog box, for Printer, choose PostScript File.
3 Choose the PPD for the final output device.
4 View or change existing print settings. InDesign uses the current page range when creating the PostScript file.
5 Click Save.

About device- and driver-dependent PostScript files
Select a printer and a supported driver in the Printer menu. A device- and driver-dependent PostScript file has the
following characteristics:
• It is driver-dependent. The PostScript file will contain code generated by InDesign and by the driver. The InDesign
code is primarily responsible for the page content, including font downloading, and for setting basic device infor-
mation, such as media size, resolution, and screening. The driver is primarily responsible for setting special driver
features, such as watermarks, and for enabling or controlling special device features. Since InDesign doesn’t have
complete control over creating the PostScript file, the level of DSC compliance isn’t quite as high as it is with
driver-independent PostScript files. The level of DSC compliance, and therefore the PostScript file’s suitability for
prepress tasks, depends on the printer driver used.
