Screening Prints Wear Out By Being Watched

A film print is a physical object that degrades through use. Each pass through a projector adds scratches, weakens perforations and risks a break, which puts an archive's two purposes directly against each other.

Projection is mechanical stress

The mechanism pulls film through by its perforations and holds each frame still for a fraction of a second, applying repeated force to the edges of a plastic strip.

Dust and grit on rollers cut fine lines down the length of the print, and those marks accumulate permanently across a print's showing life.

Splices are the weakest points, and an old print carries many of them, each a place where tension can tear the film during a run.

Archives distinguish between kinds of copy

A preservation element is not for showing. It is stored cold, handled rarely and exists to generate other copies if they are needed.

An access print or a digital copy takes the wear instead, which is the standard arrangement and the reason most archive screenings do not use the rarest material.

The difficulty arises where only one print exists, since there is nothing to make an access copy from without running the object being protected.

Scanning is itself a handling event

Digitizing a fragile print requires transporting it, inspecting it, repairing splices and passing it through a scanner, all of which carry risk.

Specialized scanners reduce that risk considerably by moving film gently and by handling shrunken or damaged stock that a projector could not accept.

The decision to scan is still a judgment about whether the print can survive the process, and some material is assessed as too fragile to attempt with current equipment.

The projectionist is part of the preservation system

Archive screenings are run by people who inspect a print before it goes on, clean the path, and often run it at lower speed or on equipment adapted for old stock.

Handling conventions matter as much as machinery: how a reel is wound, how it is stored between shows, how quickly a fault is caught.

A print run carelessly once can be damaged more in an evening than in twenty properly managed screenings.

The argument for showing anyway

Against all of this sits the case that an unwatched film is preserved for nobody, and that archives justify their funding partly through public programming.

Screenings also build the constituency that pays for preservation, and a restoration with an audience is easier to finance than one without.

So the decision is made title by title, weighing rarity against condition, and it is one of the few areas where an archive's two obligations cannot both be fully honored.
