O.K. it's 9.00a.m. & I'm making up a print just delivered.
The print had been left in a trailer/van overnight (-3 degrees Celcius)& delivered first thing this morning.
It is very cold to touch & I am going to leave it for a few hours till it warms up to throw it on the platter.

My question is, could I damage it by making up when it is that cold?

I wouldn't want to make up that print right now. THe way I inspect it I would be afraid that it might cut into my fingers. I would let it get up to room tempreture.

During the winter months, I prefer to allow the film to reach room temperature. Otherwise, the moisture in the air may condense on the film, making a sticky mess, particularly in a properly-humidified booth.

I agree with Adam that the greatest risk is moisture condensation on the cold film. Let the film rolls warm up before opening the film cans/cases. Condensation on the film could make the gelatin emulsion sticky or cause ferrotyping.

Thanks every one, John, no links?

I read most of the stuff you post & thanks again for "adding a background" to the every day workings of the industry.

As a footnote, some archives deep-freeze film elements deliberately in order to inhibit colour dye fading. However, these elements are frozen inside an airtight container to prevent condensation forming on the film surface, and also stored in a low humidity as well as a low temperature environment. When they are needed for use, they are ramped up to room temperature in an acclimitisation room, usually over a period of several days.
