Letterpress is not difficult to do badly, and it is surprisingly difficult to do well. The machine is simple — a flat bed, a form of type, an inked roller and enough pressure to transfer ink — but almost every part of the process carries a tolerance measured in thousandths of an inch, and the press will tell you immediately when you have exceeded one. This guide covers the order in which to buy things, what the numbers mean, and where a first workshop usually goes wrong.
The single most useful thing to understand before spending anything is that letterpress is a dimensional process. Everything inside the printing area — type, furniture, quoins, blocks, and the base a photopolymer plate sits on — must add up to exactly type-high, which is 0.918 in (23.32 mm) from the bed of the press to the face of the printing surface. Get that right and a cheap press will print beautifully. Get it wrong and the best press in the world will quietly crush its own type.
Three routes in, and what each one actually costs
There is no single entry point. The three common routes differ less in price than in what they let you print, and choosing the wrong one is a dead end rather than a mistake you can correct later.
| Route | Typical bed | Footprint | Best for | Main limit |
|---|---|---|---|---|
| Tabletop platen | 3 × 5 in to 8 × 5 in | A kitchen table | Cards, invitations, short runs | Cannot print larger than the bed |
| Floor-standing platen | 10 × 15 in | 1.2 × 1.2 m plus working space | Work up to roughly A3, repeat runs | Weight — often 400 kg or more, and a solid floor |
| Cylinder proof press | 15 × 22 in and larger | About 2 m of wall | Long text, large sheets, light impression | Slow; one sheet at a time, hand-inked |
A tabletop platen will print a business card in one pull and a folded card in two. That is genuinely enough to learn on, and the small chase keeps you honest about lockup because there is no room to be sloppy. The trade-off is scale: an 8 × 5 in bed cannot print a poster, however good you get.
Not the largest you can afford — the largest you have a permanent, level home for, on a floor that will take the weight, with a clear metre of space beside and behind it. A floor platen that has to be moved twice is a floor platen that gets sold.
Type-high, and why nothing in the form can be approximate
Type-high is the one number that governs the whole craft. Lead type is cast to 0.918 in; so is the furniture that fills the gaps in the chase; so are the quoins that lock it all together. A photopolymer plate is only a few thousandths of an inch thick, so it is mounted on a base machined to bring the assembly up to type-high exactly. A base that is 0.005 in under will not print at all. A base that is 0.005 in over will print, and then begin hammering the bed.
- Type and spacing material: 0.918 in (23.32 mm), foot to face.
- Furniture: 0.918 in, so it locks against type without rising or falling.
- Quoins: 0.918 in, expanding as the key is turned to wedge the form tight.
- Plate base: whatever thickness brings plate plus base to 0.918 in exactly.
If a quoin needs real effort to tighten, something in the chase is over height or oversized. Forcing it bends the chase, cracks the quoin and can spring the bed. Take the form apart and measure it.
The supporting kit nobody mentions in the first conversation
The press is perhaps half the initial spend. The rest is the tooling that makes it usable, and that is the part which catches people out, because it never appears in photographs of letterpress studios.
- Chases to fit the press — two, if possible, so one form can be locked while another prints.
- Furniture in a range of widths: wood for large gaps, metal for fine adjustment.
- Quoins and a quoin key. Two per form as a minimum, three on anything over 10 in wide.
- Gauge pins for repeat registration, plus a pica pole or a rule marked in picas and points.
- Ink knives, a glass or stone slab for rolling out, and a small brayer for touching up.
- Rollers — and rollers are consumable. Rubber hardens and glazes, and a glazed roller will not carry an even film.
Ink, rollers and the first impression
Letterpress ink is a paste, not a liquid. It is stiff enough to stand up on the slab, and it transfers as a film of roughly 0.001 in. Rubber-based inks suit a small workshop because they stay open on the slab through a working session and clean up with a wash. Oil-based inks print a harder, slightly glossier film and dry largely by oxidation, which takes hours to days depending on the stock and the drier already in the tin.
Roller setting matters more than roller condition. The roller should just kiss the type face and the ink plate, with a strip of paper sliding out with slight drag between roller and plate. Too much pressure and the roller distorts, which makes the ink film uneven across the form and prints a dark band down one side.
Lock and plane the form
Tighten the quoins, then lay a straightedge across the face. Any type that rocks or sits proud will print dark or crush. Tap it down and check again.
Ink up thinly
A pea-sized bead on the slab, rolled out until the brayer sounds faintly tacky and the film is even. Too much ink fills the counters of letters and closes up fine hairlines.
Set the impression, then reduce it
Bring the platen or cylinder down until you get a print, then back off. The target is the lightest pressure that gives a solid, even image — a kiss impression — unless you are deliberately printing deep.
Print and adjust
Two or three sheets to settle the ink, then assess. Patchy printing usually means uneven packing or a form that is not planed, not a shortage of pressure.
Beginners almost always over-ink and over-impress. The look associated with letterpress comes from paper being pressed into the type, but the depth involved is a few thousandths of an inch — 0.002 to 0.006 in on a soft cotton stock. Go past 0.010 in and you are embossing the reverse of the sheet, crushing the fibres, and shortening the life of the type.
Where a first workshop overspends
- A large collection of decorative type before any body type. One 12 pt serif in roman, italic and small caps will teach you more than fifty novelty faces.
- A deep-impression plate base bought before the press is set up properly. Depth is a property of press, packing and paper, not of the base.
- A drying rack sized for production before you can print twenty sheets in a row without a spoilt one.
- Finishing equipment — hot foil, gilding tools, a board shear — which belongs to different crafts with different budgets.
A realistic first project
A single-colour card on 300 gsm cotton stock is the right first job. It teaches lockup, registration, ink density and drying in one afternoon, and it produces something you can actually give away. Set a short line of type, lock it with two quoins, print fifty sheets, and look at them the following morning in daylight. That comparison — yesterday afternoon against this morning — teaches more about ink on paper than any amount of reading.
What the first six months actually look like
The learning curve is not a curve so much as a series of specific failures. In the first week the problem is registration. In the second it is ink density. Around the third week the form starts to move during a run, which is almost always a lockup that was tight enough for one pull and not for fifty. Somewhere in the second month the rollers glaze, printing goes pale and streaky, and you learn what a roller wash is for.
- Weeks 1–2: single-colour, one-line forms. Learn the press and the packing.
- Weeks 3–6: two-colour registration with gauge pins. Learn to plan the second pass before printing the first.
- Months 2–3: mixed type and a plate on a base. Learn that height consistency is the whole game.
- Months 4–6: a genuine run of a few hundred, with drying and stacking planned in advance.
None of this requires a large budget. It requires resisting the urge to print something ambitious before the simple thing is repeatable.
Number them and pencil the press settings on the back. A month later they are the only reliable record of what worked, and they are more useful than any note taken from memory.
The press does not care what you intended. It prints what is in the chase, at the height it is, with the ink you put on it.A printer, on the first morning of an apprenticeship
Start small, learn the dimensions, and let the work grow. Letterpress rewards patience far more than budget — a well-set form on a modest tabletop press will out-print a badly set form on a floor platen every single time.
