------------------
Travis, in the course of testing and evaluating wide-format copiers (which
today are essentially scanners with an attached printer), we found that the
two Xerox models we tested were "fooled" into making an incorrect exposure
by the reflectivity of the Mylar encapsulation. Overcoming this problem
required turning off all of the automatic-exposure and automatic-correction
features, which is unacceptable to us for reasons of productivity.

The Océ model and the Ricoh model we tested were not fooled by the Mylar
encapsulation.

We noticed no significant problems with resolution or dimensional stability
from the Mylar encapsulation. HOWEVER, the majority of our drawings are
engineering and architectural rather than cartographic, and small
differences in resolution or dimensional stability are somewhat less
significant in those fields.

Best regards,

Fred.

I am starting a major campaign of map encapsulation. However, at some point
I would like to scan a number of these maps. Is it possible to scan
encapsulated maps, will it hurt the scan quality? Any help that people can
provide would be appreciated.
