Digital Restoration Process
We know you're meticulous with your gear and expect the same of
your documentation, that's why we utilize a restoration process
that ensures documents of high quality and durability.
1st Generation Scans: Unless specifically noted
on the individual item, you can count on our manuals being produced
from originals. None of our standard offering of vintage documents
are taken from 2nd or 3rd generation copies of the originals. However,
there are a few instances where customers have asked that we reproduce
from a copy when very rare documents are concerned.
Resolution: We scan our literature at 400 dpi
and digital restore each item as described below. Don't be fooled
by other sellers who claim they scan and print at 1200 dpi... While
it's technically possible, there is no benefit since by 400 dpi,
all possible resolution has been extracted from a printable image.
By comparison, professional color photographs are printed at 300dpi.
All of our documentation is scanned on an industrial scanning device
designed for extremely high quality and accuracy.
Digital Restoration: We spend a significant amount
of digitally removing stains, handwriting, notations and other non-original
marks from each page where possible. Photos are optimized, text
is darkened, and contrast is increased to produce a crisp document
that easy to read. Where schematics or other diagrams fall on foldout
pages, we digitally join these to create one unified image and reproduce
them in landscape format. Where appropriate, we may enlarge original
diagrams or photo's where the originals were hard to read or unclear.
These processes allow us to create a reproduction that is superior
to photocopies and old or damaged originals.
Paper and Binding: Quality 24lb stock with a brightness
level of 94 is used for the body of each of our manuals. The body
is then enclosed in clear front & back covers and bound via
the Comb Binding process, so that it will lie flat while in use.
Printing: All manuals are printed in grayscale
