CCITT Group 4 (G4 MMR) - this provides loss less compression, this format is widelysupported, but some document types may not compress significantly.b. JBIG2 - JBIG2 compression is usually used for text and halftone documents. It yields a verysmall black and white file size with fast viewing performance, but the initial scan performanceis typically slower. This compression format requires Acrobat 5 with PDF version 1.4 or greaterc. Flate Compression - Flate compression works well on bi-level or color images, or with generaldata. It is a loss less compression format that combines LZ77 and adaptive Huffmanencoding (RFC 1951). When used for PDF documents, Flate compression is applied after JPEGcompression. It is also used in place of G3 compression for monochrome PDF images in Photoand Magazine mode.d. MRC Compression - Mixed Raster Content (MRC) encoding extracts image components intolayers and compresses each layer according to its content characteristics. MRC encoding canmodify images causing image quality artifacts by the extraction and compression process.The MRC Compression settings allows you to customize the compression that will be appliedto images that contain both text and images. Text and image parts are compressedseparately using the best type of compression for each part.e. If you enable MRC Compression. The MRC Compression Format options will display. Selecteither [Multi-Mask Compression] or [3-Layer Compression].f. 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 smallblack and white file size with fast viewing performance, but the initial scan performance istypically slower. This compression format requires Acrobat 5 with PDF version 1.4 or greater.The following options can be selected:• Enable Arithmetic Encoding• Enable Huffman Encodingg.
