Re: ?digital scanning textiles?

[Margaret Geiss-Mooney <mgmooney@xxxxxxxxxxxx>]

Good morning, TexCons'ers - I think the EMG specialty group of AIC (or maybe
it's Book & Paper) has had presentations about this - Tim Vitale is one of
the conservators as my foggy brain recalls is/was involved in the light
outputs of scanners (something to do with scanning documents, etc. for a
digitization project?). A search of the CoOL archives will probably bring up
more useful references from the past.

>>Hi everyone: here's a question I just got: is it ok to scan antique
textiles on the digital scanner? The advantages are that the image is 1:1;
the front and back can be scanned; it's easy; it's quick. The disadvantages
would seem to be the bright light and it's duration over a small section of
a textile art work. At SCMRE our scanner uses a xenon gas cold cathode
fluorescent lamp. It appears as though the peaks of the spectrum exclude
ultraviolet but include infrared at least for one manufacturer. Certainly
the glass cover would act as a filter, but has anyone put a light meter
against one of these scanners to determine the footcandle or lux level that
a textile would receive? Mary>>
