Rate at which input pixels (coming from the RIP or test pattern generator) are
duplicated in the subscan direction before being imaged. Pixels are duplicated
when the output DPI is physically limited to a higher value than the input DPI.
Must be chosen carefully with the other mode parameters. Do not modify.
If the head is 2400 dpi and the RIP is set to 1200 dpi, the DPE needs to send
four pixels to the head for every pixel it gets from the RIP -- two pixels in
the subscan direction and two in the mainscan direction. This parameter tells
the DPE to duplicate the received pixel from the RIP in the subscan direction
when sending it to the head.
This parameter must be set to 1 when imaging certain proofing medias on the
Spectrum and Proofsetter machines that need overwriting enabled. See the
NVS parameter "media ow" for more information.
