TIFF overview

Common Controller
The purpose of this section is to provide you with information for
creating TIFF files that can be submitted to the DocuSP
controller and to provide information about the type of TIFF files
that will increase printer productivity.
Prior to DocuSP 3.1, the controller utilized a conversion tool
(TIFF to PostScript) to process and print TIFF files. A native
TIFF decomposer has now been implemented to directly process
TIFF files for printing. This improves the TIFF printing
performance for certain types of files. Decomposer level
adjustments are also now available for the TIFF decomposer at
the Queue level.
NOTE: Multipage TIFF files are now supported. Single TIFF
files can now contain multiple TIFF images to be processed and
printed.

Performance considerations

Optimum performance can be achieved for printing TIFF files by
following the guidelines listed below:
• Use CCITT Group 4 compression for speed.
• Use a resolution of 600 dpi to eliminate the need to scale the
image.
• Use a TIFF orientation tag value of 8 to eliminate the need to
rotate the image.
• Use single strip image data to eliminate additional image data
manipulations.
• Use a value of 1 for Fill Order to eliminate additional image
data manipulations.

Supported TIFF tags

Below is a list of the TIFF tags supported by the DocuSP
software.
