Large Format Scanners are probably more
specialist than book scanners and the company vary
the way they use the CCD and illumination in their
model range.
q Synchron Table models – fixed head, fixed light
with moving document table
q Synchron Professional – fixed head, fixed side
lighting, fixed document.
q Synchron Light models – moving light, moving
document, both synchronised to the CCD.
By using the light and the CCD (Synchron Light
models) at different set angles (10º and 20º) these
systems can be made to detect wood grain and the
brush strokes in an oil paintings. Objects up to
100mm (4”) thick can be scanned with a depth of
field of between 25mm (1”) and 50mm (2”). The
document size can go up to 1500mm (59”) by
2235mm (88”) and the CCD heads can be either
220MB or 450MB. The larger camera means that at A1 the resolution would be:
450MB = 24” x 36” x 3 x dpi²
dpi² = 450 / (24 x 36 x 3 )
dpi = 416 resolution in RGB
