• Sub-sampling (non-JPEG): Sub-sampling is standard with JPEG. Support also for sub-sampling
of non-JPEG images is now added. The only allowed sub-sampling ratio for the Cb and Cr
bands is 2.
• Concatenated ABIC: A 4 or 8 bit/IDE gray ABIC format, also known as ABIC grey. This format
has been specified as an alternative to TIFF or Fax-4 for the US Federal Reserve “Common
Output Format” (Check 21 - scanning and reprinting). The widely used IBM 3890 check sorter/
scanner can generate concatenated ABIC images.
IOCA FS 40
FS 40 can be described as a tiled version of FS 10 and is only used for monochrome bi-level
images. This format is rarely used.
IOCA FS 42
IOCA FS 42 is an old image format which was designed for the Infoprint Color 100. The images
were pre screened, therefore is IOCA FS 42 not a suitable format for modern B/W or colour
printers.
IOCA FS 45
FS 45 images are tiled images with four 8-bit multilevel planes, C, M, Y, and K. Each colour plane
is compressed separately - LZW or JPG compression is used. The FS 45 image will be converted
to gray or to Device CMYK using colour management. ICC input profiles can be invoked with the
IOCA image. The quality of the image has improved over earlier versions.
IOCA Colour Management
IOCA Colour Management is used in this version. FS 11 JPEG images may contain an embedded
ICC source profile or invoke an external CMR with a source profile. Other image types can only
invoke a CMR. A default source profile will be used when no profile is provided.
