Hint and Tips
For work-and-turn jobs (flip media in length of table direc-
tion),
1) Verify the gantry origin offset is set so the first possible
printable pixel (zero location) is the left edge of the media.
2) Measure the exact length of the media and enter this in the
PosterShop layout Preview Dialog Height (Vertical) field.
3) Select Center Vertical.
4) Print the Image, then flip the media and print on the back-
side.
For work-and-tumble jobs (flip media in the width of the ta-
ble direction)
1) Measure the exact width of the media and enter this in the
PosterShop Layout Preview Dialog Width (Horizontal) field
2) Then select Center Horizontal.
3) Print the image, then flip the media and print the backside.
The Arizona 250 GT is capable of printing full bleed images,
i.e. images printed slightly larger than the media size to en-
sure that the printed images goes to the all the way to media
edges. However, since this implies some ink will be printed
off the media is it very important a sacrificial scrap piece of
media - either the same height or up to 1 mm less be placed
on the bleed edges of the media. Failing to do so causes ink
to accumulate on the print head nozzle plates and car-
riage face plate and will, over time, degrade printer per-
formance resulting in banding.
A variety of scrap materials can be used be used to mask off
unused vacuum areas. Vinyl and cut vinyl transfer paper that
is sticky on one side are good choices. The mask media can
hang of the vacuum control side of the table. Masks can either
be strips or templates with cutouts where the piece or pieces
of media are to be placed. Remember to not use a media
masking material that is thicker than the media to be printed
on.
Use the vacuum bleed valve and gauge to reduce the amount
of vacuum to the minimum amount required to hold the me-
dia to the table when printing on porous and flexible media.
This will reduce artifacts caused by the vacuum holes in the
table. Also, an MDF spoil board (similar to boards used on a
router table) can be used to eliminate artifacts caused by the
vacuum holes.
