If you require very high accuracy, you can modify the vertical
precision to a value between -1% and 1%. Positive settings mean
that the distance between scan lines will be increased, and negative
settings mean that the distance between scan lines will be
decreased. When you exit the Scanner Setup dialog, the modified
value is stored in non-volatile memory in the scanner and can be
changed only by re-doing the setup.
The procedure for vertical precision adjustment would be to scan a
precision original and measure the vertical distance between points
in the image in a CAD or GIS system. Then compare those with
similar physical measurements between the points on the original.
You should scan at the scanning resolution you will later be using
for the end result.
tell me about paneling and tiling options
Paneling enables you to create huge enlargements. With paneling
you print wide format sections of your image as ‘panels’ and then
glue the panels together to reconstruct the image. In effect, the
Paneling option creates a virtual printer with unlimited width
capabilities. The HP Designjet scanner software makes paneling
easy by supplying precisely placed cutting lines and guiding glue
marks on the panel edges, so you can connect your panels with
near-invisible seams.
Tiling is also paneling—but gives you the option to make your panel
sections by dividing the image both horizontally and vertically.
options
• Width: for setting the width of the panels.
The width includes the Overlap area. The panel width can at
most be as wide as the printer’s printable area. For maximum
sized panels, set the panel width to the same value you set as
the printer’s Media Width (through the Setup tab > Printer >
Unprintable area) minus the printer’s left/right unprintable
areas.
This value should correspond with the documented printable
area for your printer. The scanner software will calculate the
size of the last panel. When calculating special panel widths,
for example for dividing the image into equally wide panels,
you must remember to add extra space for panel overlap (see
the example below).
