PDF Image Only Output Format Window

When the recognition profile is set to Kofax PDF Image Only, use this window to configure PDF output preferences.

Output format

Select the output format that is generated by the PDF Image + Text recognition engine and saved to an external file:

  • Kofax PDF: File format that lets you view a document on any computer system while preserving the layout.

  • Kofax PDF/A: File format based on PDF that supports the long-term preservation of digital documents. PDF/A files often have larger file sizes than PDF. This option also includes tags in the PDF document.

The availability of other settings on this window may vary, based on your output format selection.

Resolution

Set the resolution of the images for the PDF document being saved as an output file. You can select from the following output resolutions in dots per inch:

  • 72

  • 96

  • 120

  • 200

  • 240

  • 300

  • 360

  • 400

  • 600

Note If necessary, you can improve image quality results by increasing the resolution setting from the 72 dpi default resolution. The maximum setting that can be implemented is equal to the original image resolution value. For example, if the original image resolution of the scanned page is 200 dpi and the resolution is set to 300 dpi, the image resolution of the output file is 200 dpi rather than 300 dpi.

Compression format

Use the list to select a compression output format for the PDF.

By default, the selection is JPEG, which is supported for color and grayscale images. If you are processing bitonal images while JPEG is selected, CCITT4 is used instead.

Note If you select PDF/A, the JPEG 2000 format is not supported.

JPEG Quality

Specifies the JPEG quality for color pictures saved in the output file. The quality range is from 1% to 100%, with 100% being the best quality.

PDF Version

Select one of the following PDF versions to use for the output:

  • Auto

  • 1.3

  • 1.4

  • 1.5

  • 1.6

  • 1.7

When you select Auto, the application automatically determines the PDF version number.

PDF/A Compliance

If Kofax PDF/A is selected as the output format, select the level of PDF/A compliance:

  • PDF/A-1a: (default setting): Supports long-term storage of digital documents and fully satisfies the requirements in the ISO 19005-1 specification. Readable by any PDF reader that conforms to PDF 1.4, or later.

  • PDF/A-1b : Offers the same level of compliance as PDF/A-1a and satisfies the minimal requirements in the ISO 19005-1 specification.

  • PDF/A-2a: Offers the same level of compliance as PDF/A-1a, and adds support for JPEG 2000 compression to generate reduced file sizes. Satisfies the requirements in the ISO 19005-2 specification. Readable by any PDF reader that conforms to PDF 1.7.

  • PDF/A-2u: Offers the same level of compliance as PDF/A-2a, and adds the ability to extract text in Unicode.

  • PDF/A-3a: Permits the embedding of another PDF/A file or a binary file format (such as XML or Microsoft Office) within the PDF/A file. Satisfies the requirements in the ISO 19005-3 specification. Otherwise, the same as PDF/A-2a.

    Note With PDF/A-3a compliance, only the PDF/A file, rather than any embedded file, should be considered for archiving purposes.

  • PDF/A-3u: Offers the same level of compliance as PDF/A-3a, and adds the ability to extract text in Unicode.

Image Compression

Select an image compression profile from the list.

Edit button

Modify an existing image compression profile or create a new one. The Image Compression Profiles window appears so you can specify the type of image compression to use.
