==General Best Practices==
'''Before the show''':
 
* Open film cans as soon as print arrives to check for any damage incurred in shipping and to make sure you received the correct film (and all the reels are there).

===Print Arrival===
* Open film cans as soon as print arrives (even if you don't have time to inspect it until later).
* Check to make sure it’s the right film, that all the reels are accounted for.
* Check shipping reel condition etc, taking note of in transit damage (let the lender know immediately if print has been damaged in transit).
* Check for things like [[DTS]] discs or special instructions from the archive.
* Leader not taped down, tangled leader? Check to make sure there’s no damage to the first few feet of film.
* Take special care when handling prints on [[core|cores]]. Always support the entire reel when moving them, loosely wound film on a core can be disastrous if not handled properly

'''During projection''':
===During projection===
* If possible, use 2000 ft. reels and a dual-projector [[changeover]] system. NEVER use [[Platter Systems|platters]] or build [[archival prints]] onto reels larger than 2000ft.
* If possible, use 2000 ft. reels and a dual-projector [[changeover]] system. NEVER use [[Platter Systems|platters]] or build [[archival prints]] onto reels larger than 2000ft.
* If using a [[Platter Systems|Platters System] to screen non-archival prints, routine maintenance and calibration of system is a must.

* If you're running small gauge film, do not have a changeover system, and have received permission from the archive to build onto larger reels, do not remove the heads and tails when you build the print. You'll have to close the dowser during the show as the heads and tails run through.

* If possible, do a post-screening inspection of the print to make sure no damage was incurred during projection.

====Practices to avoid====
===Storage===
*Upon receipt, prints should immediately be moved to the booth or another secure storage location.
*Film should never be stored in inappropriate areas where damage could occur, such as concession areas or kitchens.
*Film should be stored in a climate-controlled room. A relative humidity of 50-60% is ideal. Dry conditions can cause [[spoking]] and exacerbate issues with static, while damp conditions can contribute to film degeneration, particularly when dealing with acetate and nitrate [[film stock|stock]]. For acetate film, damp storage conditions can accelerate [[vinegar syndrome]] or naphthalene syndrome. Even polyester can be damaged by moisture. When polyester is stored in damp conditions for an extended period, the layers of film can stick together, resulting in emulsion damage when rewinding. In extreme conditions, the film may tear when attempting to separate the layers.
*After inspection, film should be stored in an enclosed reel cabinet. The reels should NOT be stored with the heads hanging out of the cabinet.
*Reel cabinets should be cleaned on a regular basis.
 
==Practices to avoid==
* Using plastic shipping reels as take-up reels. Using damaged or bent [[reels]].
