Default Ilford 11x14 film specs

Hello,

I need to know the dimensions of Ilford 11x14 sheet film. I've tried to
download the info from the Ilford website, but my software can't read the pdf
file. Could someone forward the info to me?

Thanks

Curt Blood

Do you - for example - mean this one he

http://www.ilford.com/html/us_english/pdf/FP4Plus.pdf

It doesn't tell anything about sheet film sizes. It only says that
the film "is available in a wide range of standard sizes".

Well, that's not exactly the information you are looking for... I
also checked the German version of this document, but
unfortunately, there is no difference.

I think you should contact Ilford directly and ask them. That will
be the most reliable way to get these data.

Availability of 11x14 in a specific emulsion is best gotten from
the vendor: B&H sells HP5+ in 25 sheet 11x14 packs, for instance.

A large enough vendor can have the film made for resale in any
desired size. A minimum quantity would apply and the price would
be higher. But it is possible that only B&H carries FP4 in 3 1/4 x
4 1/4, and that's because it is the size they ordered it in.

This sort of splintered information drives folks (including me,
who [theoretically] know why and how this is done) nuts.

You have to think like an Engineer: the above specification sheet is
not for the film as a roll/sheet but for the emulsion coated plastic
that is used to make a roll or sheet of film.

You will usually find there is document for each separable step
in the manufacturing process.

The emulsion feedstock is what is described in the spec above.
It says nothing about the size the feedstock is cut into, where
the gelatin comes from ... Only those things that are uniquely
'FP4ish' are specified.

Now a box of sheet film made from this emulsion would have a
separate document specifying format/sheets per box/packaging for
the pack and ship operation. This would tell you that they
do make the stuff in 11x14.

A separate document would specify the actual dimensions
and tolerances for 11x14 format film. This is done because
raw 11x14 flows from a silting/cutting/notching operation
into a packaging operation that places the film into
consumer cartons, bulk cartons for Adorama, 25 sheet/50
sheet, 100.... A change in the color of the carton, or the
discontinuance of 50 sheet packs has nothing to do with the
properties of the emulsion or the size of 11x14.

The actual physical size of llx14 film would be found
in an ISO, ASA, NBS, SPIE ... specification, as all film
manufacturers make 11x14 film in the same actual size (which
is most likely _not_ exactly 11x14 inches).

Think 'need to know'.

I guess serving the end-user's "need to know" by having everything in one
place--a "one-stop" document--would be too easy and wouldn't make sense from
an engineer's point of view, huh?

The Bush administration should restrain itself from its imperial arrogance
that has so alienated countries around the world. Their contempt for the
United Nations in the dash to war with Iraq; their support of the coup in
Venezuela in April 2002, and the continuing hostility toward President
Chavez; the pressure on nations of the world to exempt the US from the
International Criminal Court, now joined by their contemptuous attitude
toward President Aristide must be halted. It is time for the people of the
USA to make this point clear even if the administration continues to walk
around with wax in its collective ears, with eyes closed, and ranting about
its version of the world as defined by Bush.

An ANSI standard for film dimensions: IT1.52-1994

About 1/3rd the way down.

This may not be the correct specification, but it is a place
to start.
