Recommendation
For work-and-turn jobs (flip media in length of table direction),
verify the gantry origin offset is set so the first possible printable
pixel (zero location) is the left edge of the media, if it isn't adjust it
from the Operator Control Panel field service menu. Measure
the exact length of the media and enter this in the PosterShop
layout Preview Dialog Height (Vertical) field, then select Center
Vertical. Image, let the ink dry very thoroughly, then flip the
media and image the backside.
For work-and-tumble jobs (flip media in the width of the table
direction), measure the exact width of the media and enter this in
the PosterShop Layout Preview Dialog Width (Horizontal) field,
then select Center Horizontal. Image, let the ink dry very
thoroughly, then flip the media and image the backside.
With an Adaptec 29160, use the default settings except in the
advanced settings disable the Advanced Domain Validation.
When configuring the I/O from the T220 Operator Control Panel,
set Wide SCSI: OFF & Ultra SCSI: ON. The transfer rate should
be 20 MB/sec.
When converting RGB images to CMYK in PhotoShop we
recommend that you use a 400% ink limit a, 20% dot gain
compensation, and light black generation. Good results have
been achieved printing linearized with all profiles turned off.
PosterShop online help recommends setting the Configure RIP
value of VMSIZE equal to the amount of physical memory. If you
follow this recommendation it will choke when ripping a job. If
you have 256 Mbytes of RAM set the value to 100 Mbytes, if you
have 512 Mbytes of RAM set the value to 200 Mbytes. Also
Onyx recommends not using more than 512 Mbytes of RAM as
using more actually increases RIP times.
Use ICC profiles and change default rendering intent from
Saturation to Perceptual. Also if a media has been ICC profiled
it is important to image at the same temperature. Imaging at a
different temperature/heater duty cycle may significantly change
the hue.
