Every other page in this knowledge base is about what an object was obliged to carry. This one is about whether any of it survives. A prop that is right in the hand and unreadable in the frame has failed; so has one that is beautiful at 4K and cost a week that the schedule needed elsewhere. These are the rules the workshop works to — what the lens resolves, what the camera does to paper, what has to be printed forty times before the take, and what must be made deliberately not to work.
Decide what the shot is for before the prop is designed. A viewer reads about three words a second off a screen, so a two-second insert carries one headline of five or six words and nothing else. Set that one line first, at the size the frame needs, and build the object round it. A paragraph on a prop is for the actor, not the audience — unless the camera is going to sit on it, in which case it stops being a paragraph and becomes the shot.
One-sixtieth of the frame height is the working floor: a letter whose cap height falls below it reads as texture rather than as text. That is roughly 18 pixels at 1080 lines and 36 at 2160 — on an A4 sheet filling the frame, a 5 mm cap height; on the same sheet at half frame, 10 mm. It is a rule of thumb and not a standard, because lens, focus and compression all move it, but it is the fastest way to know whether the date on the letter will be read or only seen. Measure the prop in the frame, not on the desk.
| Lines | From | What became readable |
|---|---|---|
| 576 / 480 | the whole analogue era | PAL and NTSC could not resolve a column of body type. This is why greeked filler worked: dummy text in a script nobody was expected to parse, invisible at broadcast resolution. |
| 1080 | 2006 | BBC HD and Sky HD launch, and a British audience sees body type on a prop for the first time. The pause button arrives in the living room at about the same moment. |
| 2160 | 2014 | The first streaming originals mastered in 4K, and the first productions asking for 4K-safe props. The dead columns of a newspaper, the small print of a poster and the leaflet inside a medicine carton all have to be real language in the right language. |
| HDR | 2016 | Paper white and a blown-out sheet stop being a lighting problem and become a grading one. |
A period drama is shot on today’s cameras, so the year of the story does not lower the bar. This is also why the studios have no filler mode: every column, every leaflet and every block of small print is composed in real words, because on a paused frame there is nowhere for dummy text to hide.
Hero and background are two different props, and treating them alike fails in both directions. A hero is read at full frame and must be right to the last line: one sheet, one seed, proof-read at print size, run through the studio’s Checks panel. A background prop is a silhouette and a colour, and wants twenty different sheets from the Variants zip that only have to look like a pile of the right thing. A background dressed like a hero costs the schedule; a hero dressed like a background is found by the audience at 4K.
Three framing facts the workshop plans round. The insert is where the typo is found, so the sheet that gets its own shot is the one that is proof-read twice. A portrait prop in a scope frame loses its head and foot before anything else, which moves the masthead and the signature into the middle of the sheet. And the back is in frame: a letter turned over, a newspaper folded, a carton picked up — multi-camera television sees every side of an object in one take, so there is no safe blank face.
Paper on camera is not paper in the hand. Six things change it, and five of them are decided at the paper merchant rather than in the design.
| What happens | What to do about it |
|---|---|
| The camera compresses contrast | A dense black on a bright white is the only pairing that survives the whole chain. Tonal separation that reads on the desk closes up on the monitor; a mid-grey rule against a cream ground disappears. |
| Paper white blows out | A bright sheet under the key clips before the faces do, and everything printed on it goes with it. An off-white, a cream or a lightly aged ground holds detail where a fresh 100-brightness sheet does not. |
| Optical brighteners glow blue | From the 1950s papers have carried agents that turn ultraviolet into blue light. Under an HMI, daylight or a cool LED the sheet fluoresces blue-white and a “period” document reads as photocopier paper. Period paper had none and yellowed with lignin instead. Buy a stock sold as natural or OBA-free — the archival ranges are — or age the sheet until the brightener is buried. The test is a UV torch in a dark room: what lights up blue there will do it under the key. |
| Gloss and toner flare | A coated stock throws a specular highlight straight into the lens, and laser toner has a sheen of its own that a period document should not have. Uncoated, and matte-laminated only where the object really was coated. |
| Reds bloom | A saturated red spreads into its neighbours and loses the shape of the type set in it. A red masthead or a red overprint wants to be a shade darker and a size larger than looks right on paper. |
| Colour temperature moves the stock | The same cream sheet is warm under tungsten and grey under daylight. Choose the paper under the light the scene is lit with, not under the workshop fluorescent. |
Moiré deserves its own paragraph, because it is the one that ruins a take rather than a look. A halftone above about 85 lines per inch, hairline pinstripes, engraved cross-hatching and any ruled pattern whose pitch lands near the pixel pitch at the shooting distance will beat against the sensor grid and shimmer. Coarsen the screen — 55 to 65 lpi reads as period anyway — keep ruled patterns away from a factor of two of the pixel pitch, and test with the actual lens, because moving the camera ten per cent changes it. The halftone control in Poster Studio and the engraving control in Label Studio exist for this, and their coarse settings are the camera-safe ones.
And the substrate itself. Newsprint is 42–48.8 g/m²; office paper is 80. An 80-gram “newspaper” stands up like card, does not rattle, does not fold and does not tear like one, and both the camera and the microphone notice. Buy the real thing: newsprint for papers, 90–115 g/m² uncoated for posters and bills, 70–90 g/m² uncoated for wet-glue labels, 250–350 g/m² folding boxboard for cartons. The show-through is the texture that says “newspaper” from across the room, and the sound of a prop is part of it.
Print at 100 per cent and check with a ruler. “Fit to page” shrinks a 297 mm sheet to 280 and a 60 mm carton to 57, and a carton three millimetres short no longer holds its blister. Every studio here exports in millimetres and states its trim size; measure the first print’s trim marks against it before the run. A dieline that “does not fit” is almost always a printer driver that scaled it. Then trim to size, because crop marks, colour bars and a white margin in frame are the three things that say “printed this morning”.
Life-size is too small. Hero paper props are commonly set ten to twenty per cent larger than life so a headline, a date or a name reads in a two-shot — and the cheat is made in the type, not the sheet. A broadsheet fifteen per cent oversize is spotted at once; a headline fifteen per cent oversize is not. It is the oldest trick in the department and it is why newspaper headlines in films are always a size too big. The Type scale slider does it while the auto-fit still guarantees every line lands.
Print the multiples before the take. A hero paper prop is destroyed by the scene — folded, wetted, torn, written on — and the second take needs an identical one. Six to twelve copies is normal; more for a stunt, a fire or water. Identical means the same seed: the Variants panel with the field locked prints N copies of one sheet, where a different seed gives the background stack, which is a different job. Photograph the hero before it goes to set so the copies can be matched to it afterwards.
Two rules about ageing, and the distance between them is thirty centimetres. Printed foxing, creases and stains hold from a metre away and fall apart under a macro lens, where the eye expects fibre, relief and a torn edge. So anything the lens gets closer to than about 30 cm is aged by hand — tea, sanding, a real fold, a real tear — and the rest can be printed. The Ageing panels are graded for exactly this: the lower levels are what a background prop needs printed, the top levels are the reference for what the hero needs done to it physically. And fold after printing, except where the sheet must lie flat in frame, because a fold printed as a line is a line.
Last, the actor. The lines in the script go on the prop, in the order the script has them, at a size that can be read without glasses under a dim practical. Nothing breaks a take faster than an actor hunting for the line. Print the scripted sentence where the eye lands, set the rest of the page in the same voice so the cut to the insert holds, and give the actor a copy the day before. Document Studio’s retyped lines exist for this: the scripted sentence goes in and the generator writes round it.
A visible date is a continuity fact. The moment a date is legible it is bound to the scene order, and a newspaper whose date contradicts the day of the story is the note that comes back from the edit. A hero document is signed by hand, because a printed signature is a printed signature at any resolution, and the same hand signs every copy. Rubber stamps have relief — a real stamp sits on top of the paper, skips where the pad was dry and prints heavier at the edge of the roll, none of which a flat printed rectangle does.
And a foreign-language prop is texture until it is not. A sheet in a language the audience does not read is a shape and a colour — until one member of that audience does read it, which at 4K is everybody with a pause button. That is why every language in these studios composes its own copy rather than translating the English one, and why the Greek pages carry the register of their year rather than modern Greek in an old typeface.
Three classes of detail on a prop can reach out of the frame and touch something real. A prop department’s job with all three is the same: make it look right and make sure it goes nowhere.
Barcodes. Audiences scan props. A real EAN or UPC resolves to a real product and its owner; a code with a wrong check digit is spotted by anyone who pauses on it. The barcodes here carry a valid check digit under a fictional company prefix, so a phone reads a well-formed number that belongs to nobody. Before 1974 for the UPC and 1977 for the EAN there is no barcode to draw at all, and the checker says so.
Telephone numbers. People dial what they see. Four countries reserve ranges that are never allocated to a subscriber, and those are the only numbers that are safe by construction.
| Country | From | Reserved for fiction |
|---|---|---|
| United Kingdom | 1995 | 020 7946 0xxx (London), 0113 496 0xxx (Leeds) and the same 496 0xxx block behind the other big-city codes, 01632 960xxx (no area), 07700 900xxx (mobile), 08081 570xxx (freephone), 0909 8790xxx (premium), 03069 990xxx. Ofcom |
| United States | 1994 | 555-0100 to 555-0199 in every area code. The rest of 555 is assignable and some of it is real — 555-1212 is directory assistance. NANPA; ATIS-0300048 |
| France | 1996 | 01 99 00, 02 61 91, 03 53 01, 04 65 71, 05 36 49 and mobile 06 39 98 — one block per zone and one mobile. ARCEP |
| Australia | — | 5550 xxxx behind every geographic code, a short list of 0491 57x xxx mobiles, 1800 160 401, 1300 975 707 and 1900 654 321. The American convention does not transfer: 555 is a real Australian prefix. ACMA |
| Germany | 2021 | Named blocks per city, and for mobile a list of individual numbers rather than a block — nothing else in those prefixes is safe. Bundesnetzagentur Mitteilung 148/2021 |
| Italy, Spain, Greece | — | Nothing is reserved. AGCOM’s plan sets numbers aside for emergency, public-utility and harmonised social services and for nothing else; no CNMC instrument could be found; EETT’s plan has no drama provision. The studios generate a number of the right shape for the year and say out loud that it is not guaranteed unassigned, rather than implying a protection that does not exist. |
Before a country’s reserved range existed, the right answer is a period form and not a real modern number: the lettered exchange of three letters and four figures, the 01- London code of 1966–1990, the eight-figure French plan of 1985 with its 16 prefix, a four-figure “Ruf 4821” on a German bill of the 1930s. A number whose format has left the national plan cannot ring anybody, which is a different kind of safe and an older one.
Money. Two regimes, and both are about size rather than about design.
| Where | What is allowed |
|---|---|
| United States | A reproduction of a US note is lawful only if it is one-sided and less than three-quarters or more than one and a half times the size of the real note — in any colour, since the Counterfeit Detection Act of 1992 relaxed the older prohibition — and the files and plates are destroyed after use. This is why prop dollars are the wrong size and blank on the back, and why a period drama shows money in a hand rather than flat on a table. 18 U.S.C. § 504; 31 C.F.R. Part 411 |
| Euro area | A reproduction is permitted one-sided at at least 125 % or at most 75 % of the real note in both dimensions; two-sided at at least 200 % or at most 50 %; or carrying SPECIMEN diagonally; or on a material clearly unlike paper. A drama set before 2002 is usually shot with the real, now-demonetised national notes, which are legal to own and to show. Decision ECB/2013/10, Article 2 |
A theatre paper prop is read by the actor and seen by the house, and the two have almost nothing to do with each other. The signage rule is 25 mm of letter height for every 3 m of viewing distance — one inch per ten feet. A poster headline read from row ten, about 10 m, wants caps of roughly 80 mm; from the back of a 25 m house, 200 mm. Body text does not exist from the stalls at all. So the headline is the design, and the rest of the sheet is there to be the right object in the actor’s hands. Print the poster on the set wall larger than life: the house cannot tell, and can read it.
Four consequences the workshop lives with.
And the one that surprises people coming from film: the prop faces the house, not the actor. A newspaper read on stage is held so the audience sees the front page — the actor reads the back, or nothing. A letter is “read” upstage of the actor’s face. Which means the front page is the whole show and the inside pages can be blank on a stage prop where they cannot on a screen one, and it means the masthead, the headline and the date are set for the tenth row rather than for the reader.
Every rule on this page is a card in the Archive, with the source where there is one and an empty source field where there is not — and every one of them can be argued with.
