MRC Compression - Mixed Raster Content (MRC) encoding extracts image components into
layers and compresses each layer according to its content characteristics. MRC encoding can
modify images causing image quality artifacts by the extraction and compression process. 3-
Layer Compression is a less aggressive format. For that reason, 3-Layer Compression does not
provide as much image enhancement and file size reduction as the Multi-Mask Compression
format.
The MRC Compression settings enable you to customize the compression that will be applied
to images that contain both text and images. Text and image parts are compressed
separately using the best type of compression for each part.

Text Compression > JBIG2 option will also display when you enable MRC Compression.
JBIG2 compression is usually used for text and halftone documents. It yields a very small
black and white file size with fast viewing performance, but the initial scan performance is
typically slower. This compression format requires Acrobat 5 with PDF version 1.4 or greater.
The following options can be selected:

Image Compression > Flate Compression option will also display when you enable MRC
Compression.
Flate compression works well on bi-level or color images, or with general data. It is a loss less
compression format that combines LZ77 and adaptive Huffman encoding (RFC 1951). When
used for PDF documents, Flate compression is applied after JPEG compression. It is also used
in place of G3 compression for monochrome PDF images in Photo and Magazine mode.
Check the [Enable] checkbox to enable Image Compression.

For TIFF Color Compression, select one of the following option:
•
TIFF 6.0 (old JPEG) - select this option utilizes the most universally compatible version
of the JPEG compression format.
of the JPEG compression format.
•
TIFF 6.0 Supplement 2 (New JPEG) - this is an update to the TIFF 6.0 specification and
provides a more fault-free JPEG compression algorithm, but may not be compatible with
older graphics software.

LZW (Lempel-Ziv-Welch) - this is a loss less compression method yielding very high
compression efficiency. This works best for files containing lots of 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.
