Note: JBIG stands for Joint Bi-level Image experts Group. JBIG compresses only
black and white images.
• JBIG2 Huffman Encoded: Huffman coding takes less page memory and has faster
compression and decompression than the arithmetic coding. Use this option if high-quality
compression results do not matter and you want to use less page memory.
For grayscale or color images and pages, select one of the following options:
• JPEG: This is the default setting for grayscale and color pages.
• Flate: This option saves the image data at a higher compression rate than JPEG. Flate is
lossless and does not remove data during the compression process.
