TIFF (Tagged Image File Format) Settings

Tagged Image File Format is a multi-platform format for raster (bitmapped) graphics. Nearly every graphics application can read and write TIFF. Depending upon your needs, select which version of TIFF Compression the device will use.

•TIFF 6.0 (old JPEG)

•TIFF Specification Supplement 2 (new JPEG).

•LZW - This is a lossless compression method yielding very high compression efficiency, LZW works best for files containing repetitive data, such as is the case with text and monochrome images. LZW has long been associated with TIFF and GIF images. This compression algorithm was widely used in Adobe Photoshop, until version 6, and Adobe Acrobat, until version 5.

PDF & PDF/A Settings

Select Optimized for Fast Web Viewing if you want to create linearized PDF files. Linearized PDF files allow the first page of the PDF file to be displayed in a user's web browser, before the entire file is downloaded from the web server. This fast first page display helps to alleviate Internet user frustration in waiting for an entire file to download before displaying the file's contents.

Select MRC Compression if you want to use Mixed Raster Content (MRC) compression. MRC is used to divide the scanned image based on content, and then compress each area in the optimal manner for that image area. This option allows for smaller output files with better image quality.

Note

Regarding Searchable PDF and PDF/A: If this option is available, by enabling the selection you will provide Workflow Scanning, E-mail, and Internet Fax users with the ability to choose [Searchable] as an option for their PDF and PDF/A file formats. The Searchable Format provides a second layer of data with the text of the scanned document. The second layer is converted to an optical character readable format, enabling the text of the document to be searched on, copied, and pasted, as desired.

JBIG2

JBIG is a standard algorithm for lossless compression of bi-level images (two color images), specializing in the preservation of thin lines. JBIG2 compression is usually used for text and halftone documents, and is claimed to be able to compress scanned documents up to 10 times smaller than with TIFF G4. A further claim is that it allows scanned manuals, books, check images, and other document types to be viewed and manipulated efficiently over the Internet. This method yields a very small black and white file size with fast viewing performance. This compression format requires Acrobat 5, with PDF version 1.4 or greater.

Flate Compression

Select Enabled or Disabled. Flate is a lossless compression algorithm based on two other algorithms: Huffman compression and LZ77 (the first LZW). Huffman compression is a lossless algorithm ideal for compressing text. LZ77 works well with files containing lots of repetitive data, such as text and monochrome image (TIFF and GIF) files. Flate compression is a standard feature of PDF files that Acrobat works well with.
