Aperture Cards
These cards are scanned on Wicks & Wilson
and Sunrise scanners. Black and White or
greyscale images can be produced.
Aperture
cards normally have technical drawings
stored on them.
How we
scan depends on the intended use of the
images afterwards. If they are just required
for viewing and printing at smaller size
than originals then we can scan at a fixed
reduction ratio.
If however they need to be printed back to
original size then the reduction ratio needs
to be correct for each image and this will
increase the price of scanning.
If the
cards have hollerith codes (holes for a
machine to read) punched into them it is
possible to take the indexing information
from these. If not indexing information has
to be taken form the card or the image. All
of these methods have different prices
attached to them. Please enquire for further
information.
Post Processing work
IIRI can perform a number processes to
produce various different types of output
