ocr: TIFF. S.0Appendices bit data, higher ratios can be achieved. These bitplanes often consist chicfly of noise, in which case liule or no loss ini image quality will be perceived, Palette color images created in a paint program generally compress muchi better than continuous tone scanned images, since paint images tend to be more: repctitive. Itis not unusual to achieve compression ratios of 10 lo 1 or better when using LZW on palete color paint images. By way of comparison, PackBits, used in TIFF for black and white bilevel images, does not do well on color paint images, much less continuous ton ...
