One straight line proves the fault never moved

One strip of film, running the full height of the shirt. Sprocket holes down both edges, frame lines at even intervals.

Down the whole length, one hairline never wavers. It crosses every frame at exactly the same point.

What does a straight, unbroken scratch actually prove?

That whatever caused it stayed still while the film moved past it.

A scratch that ran diagonally, or wandered frame to frame, would mean the film and the fault were moving together, or moving differently on different passes. A line that stays fixed at the same point through thousands of frames means one thing: something in the machine — a burr, a piece of grit lodged in the gate — held its position, and the film did all the travelling. The straightness isn't a stylistic choice. It's the proof.

How is a scratch different from a splice, as a mark?

A scratch records a machine. A splice records a person.

A splice sits at one point on the reel, cut at an angle, with two damaged sprocket holes marking exactly where someone joined two pieces of film — it's a single, deliberate repair. A scratch runs the length of a reel, repeating identically thousands of times a second, with no deliberate act behind any one instance of it. One is a record of a decision. The other is a record of a condition nobody decided on at all.

Why does the audience blame the film rather than the projector?

Because the flaw shows up on the one surface everyone in the room is actually looking at.

The scratch lives on the emulsion, so it appears in the picture — a fine vertical line running through a scene, in exactly the place it always runs. Nothing about how it looks tells the audience where it came from. It reads as a mark on the film they're watching, not as a fault in the metal the film is passing through, even though the metal is where the line actually started — the same way the cropped edge of the picture is decided by a plate nobody in the audience ever sees, not by the film itself.

Why is the strip drawn with no image on it?

Because the scratch is the entire content, and a picture underneath it would compete for attention.

Frame lines and sprocket holes establish that this is a length of film rather than an abstract stripe. Beyond that, filling the frames with flat colour keeps the eye on the one thing the design is actually about — a straight line where nothing else on the strip is straight.

Can I use a scratch pattern like this freely?

Yes. A hairline scratch isn't authored artwork — it's a physical mark left by contact between film and metal, and no scratch pattern belongs to anyone. Sprocket holes and frame lines are a shared technical format, the same way a fishing line's weight markings or a set of ruled staves are.

What would need permission is any actual picture drawn inside the frames — a specific scene, a specific title. This design leaves the frames empty, so there's nothing to trace back to anybody.

Does this work as a pair, for two people who worked the same booth?

It works well that way — a scratch runs the same in every reel that passes through the same fault, which makes it a fair stand-in for a shared job rather than a personal mark.

It's the same fault a rewind bench inspection is built to catch by touch before a reel ever reaches a projector — a shared condition two people both worked around, rather than a message either of them sent, which is exactly why it also works fine on its own.

Isn't a scratch just a flaw to print on a shirt?

A flaw in the picture, yes — and a genuinely interesting object on its own terms, which is a different question.

The straight line is a small piece of forensic evidence anyone can read once it's pointed out: fixed point, moving film, thousands of repeats. That's not a defect being celebrated for its own sake, it's a mechanism made visible — closer to drawing the fault than to drawing around it.

Does it print well?

Yes, and simply. A single continuous hairline against flat colour is about as clean a print as exists — hard-edged, high-contrast, nothing fine to lose in the weave except the line itself, which should be kept crisp and unbroken rather than textured or broken into dashes.

Dusty blue, slate or a worn charcoal ground suit it. One ink for the frame structure, one for the scratch — keep the scratch the lighter of the two so it reads as light catching a groove.

How do I get one made?

Describe the strip at JustOG — how far down the reel the scratch runs, how many frames are visible, how worn the sprocket holes look. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.

Designs other people have published are in the shop.

Every frame, the same line, in the same place, for the whole length of the reel.
