2. How does DESKSCAN 6 work?
DESKSCAN
6 is a large format desktop color scanner, which
utilises a unique method developed and refined over
several years.The system uses an A4 motorised scanner,
which moves up and down a specially calibrated guide,
to capture the document in several strips in a variety
of raster file formats.
The
guide is then manually moved at the end of each
strip scanned. This is a straightforward process.
Simple cut outs on the base edges; make relocating
the guide easy and the software does all the hard
work.
Each
strip is saved and then automatically corrected
for distortion and joined by the advanced software
using complex mathematical algorithms and the unique
optical recognition of control points at 1cm (0.44')
intervals.
The
end result is a precisely matched, seamless image
in 24 or 8 bit color, 8 bit greyscale or black and
white ranging from 76 up to a true 600 dpi.

6 produces a seamless image in 24-bit or 8-bit color,
8-bit greyscale or black and white at resolutions
up to 600dpi.
5.
How long does it take to scan an image?
Scan
speeds are as follows:
Black
and White
A0
scan at 100 dpi - 2 mins
A0 scan at 200 dpi – 3 mins
A0 scan at 300 dpi - 4 mins
A0 scan at 400 dpi - 5 mins
Color
A0
scan at 100 dpi - 4 mins
A0 scan at 200 dpi - 5 mins
A0 scan at 300 dpi - 7 mins
A0 scan at 400 dpi - 9 mins
(Please note that these speeds are for a typical
configuration. Speeds will vary according to computer
speed, hard disk speed, port speed and available
memory)

How do I save to different formats?
To
save the document to a different format you need
to export the layer. To do this, choose Export from
the Layer menu. Change the format the one desired
and save the document.
7.
Can I scan larger than A0 (E size)?
You
can scan documents larger than A0 (E size) so long
as the control crosses near the top and bottom of
the drawing are not covered. They need to be seen
by the scanner so that the software can align the
strips for joining. In other words you can scan
as many strips as you need, however they cannot
be any higher than the guide that is 870 mm.
8.
Please explain the Clip Noise function?
When
a document is scanned, each color on the original
document is normally captured as several shades
of that color. This is due to both noise and lighting
variations picked up by the scanning system. This
becomes particularly important for black and white
as these colors most often represent the background.
In order to correct this problem two commands have
been provided, Color - Clip Noise - Lower and Color
- Clip Noise - Upper. When either of these commands
are selected, a palette is offered that contains
the layers palette sorted on average intensity.
If clipping the lower end of the palette, the title
of the dialog will be 'Select highest to clip' and
when clipping the upper end the title will be 'Select
lowest to clip'. When you 'Select highest to clip'
then all entries in the palette below and including
the selected entry will be modified to be black.
The 'Select lowest to clip' will modify every entry
above and including the selected entry to white.

How do I change image resolution?
Within
all images there is a resolution that relates the
image dimensions back to the paper size that it
was derived from. DESKSCAN Express uses this information
to reference sizes in real units like millimeters,
centimeters and inches. In some cases the value
stored within the image may be in error so a menu
command File - Modify Resolution - Edit has been
supplied. This is a very simple command that requests
a new resolution and replaces the value. If however
a new image is required at a different resolution
but the resolution in the current image is correct
then the command File - Modify Resolution - Convert
should be used.
This command uses the scaling capability
to re-sample the image as if it had been scanned
at a different resolution and at the same time it
replaces the resolution with the new value. As an
example is an image was 1000 pixels wide and it
had a resolution of 400 dpi then entering the command
File - Resolution - Convert and entering the new
resolution as 200 would result in an image 500 pixels
wide and resolution of 200. It must be emphasised
that no averaging or interpolation is used for this
process so it should only be used when necessary
and the results treated accordingly. Also as the
conversion changes the document dimensions it will
become bound as part of the process.
