Figure 5. PrimoPDF PDF Output Options
![]() |
Screen. Produces a PDF optimized for screen viewing. This configuration creates small PDF files and reduces image resolution to 72 dpi, which may reduce print quality. |
![]() |
Print. Produces a PDF optimized for printing to most home and office printers. |

eBook. Produces a PDF optimized for eBook usage. |
![]() |
Prepress. Produces a PDF optimized for printing to commercial-quality printers. This configuration creates large PDF files and will automatically embed all fonts and high resolution images for best results when printed on a system other than the one on which the PDF was generated. |
![]() |
Custom. Enables you to specify custom settings for your PDF output. Refer to Setting PrimoPDF Custom Preferences for further details. |
PrimoPDF Document Properties allows you to specify a title, subject, author, and keywords for your PDF document. This supplies users with basic information about the document, and provides a useful way to search for information.

Figure 16. General Settings
PDF Version. Sets the PDF version for compatibility with PDF viewing and editing applications.
PDF Resolution. Sets the resolution for the entire document.
Auto Rotate Pages. If set, PDF page will be automatically rotated so that the majority of text is horizontal. This can be useful when creating PDFs from landscape documents, so that pages are easier to read onscreen.
The Color pane enables you to set options to be used in creating a PDF that contains color images.

Downsampling. Downsampling is used to help reduce the size of your outputted PDF file. It allows you to optimize the images in the PDF to achieve the best balance between visual quality and file size. Downsampling reduces an image's resolution (to the resolution specified) by discarding pixels. Since there is less information that needs to be saved, the resultant PDF file sizes are considerably smaller.
NOTE: If you are using a downsampling technique, you need to specify the desired resolution for the outputted image. Resolution is measured in pixels per inch (PPI).
PrimoPDF has four options for downsampling color images:
Downsampling Threshold. Reduces image resolution to assist in reducing the PDF file size. You can establish a color image resolution threshold. Any images having a resolution above the value specified will be downsampled to the resolution specified.
Convert CMYK to RGB for onscreen viewing. Converts color images from the CMYK color model (used for printing) to the RGB color model (used for onscreen display).
The Grayscale pane enables you to set options to be used in creating a PDF that contains grayscale images.
