What letterpress printing is
Letterpress is a relief printing process in which raised type or image areas are inked and pressed directly onto paper, leaving a physical impression (debossed indentation) in the substrate. It is one of the oldest mechanical printing processes — Gutenberg's printing press (circa 1450) was a letterpress. In the commercial printing context today, letterpress is used almost exclusively for premium stationery, wedding invitations, business cards, and luxury packaging where the tactile impression is the desired aesthetic.
In India, letterpress declined from its dominant position in commercial printing during the 1980s–1990s as offset lithography took over. However, letterpress has experienced a significant revival since approximately 2015 — driven by the premium wedding invitation market in India, craft stationery studios in Mumbai, Delhi, Bengaluru, and Hyderabad, and a broader consumer preference for tangible, tactile products over digitally-produced equivalents.
How letterpress works — the technical process
Relief plates
Modern letterpress does not use movable metal type except in specialist letterpress studios preserving historical equipment. Contemporary letterpress uses photopolymer plates — flexible plastic plates with relief image areas created by UV exposure through a film negative or direct computer-to-plate (CTP) exposure. The photopolymer plate is mounted on a base (aluminium or acrylic) to bring the plate surface to the correct height (type-high: 0.918 inches / 23.32mm).
The impression
The inked plate presses against the paper under controlled pressure. The depth of the impression is governed by the amount of pressure applied. In commercial letterpress for premium stationery, a "deep impression" — where the plate visibly indents the paper — is the desired aesthetic and is significantly heavier than the "kiss impression" (light contact) that was considered correct in traditional letterpress.
Paper requirements for letterpress
Letterpress requires thick, soft, uncoated paper with high cotton content for the best impression. The ideal letterpress paper is:
- Cotton rag based (25–100% cotton content) — soft fibres compress cleanly under the plate
- Uncoated — coated paper does not show the impression clearly and can crack under deep impression
- Heavyweight — 300 gsm to 600 gsm for premium stationery
- Featherweight or soft formation — tight, hard-formation papers resist impression
In India, letterpress studios use imported cotton papers: Crane Lettra (USA — 90% cotton), Colorplan Cotton (UK), Gmund Cotton (Germany), and Indian handmade cotton papers from Sanganer and Khadi Gramodyog.
Ink for letterpress
Letterpress uses highly viscous, oil-based inks similar to offset litho inks but formulated for the different ink-transfer mechanism. Letterpress ink must have high tack (to transfer cleanly from the roller to the raised relief surface), high viscosity (to prevent flooding into the non-image recessed areas), and good colour strength (since letterpress typically applies a single pass of ink without the controlled dot patterns of halftone offset).
Pantone solid colours, metallic inks, and fluorescent inks are all achievable in letterpress. Letterpress cannot reproduce photographic images or continuous-tone gradients — it is a flat-colour process suited to typography, simple logos, and clean geometric designs.
The India letterpress wedding invitation market
India's wedding invitation market is one of the world's largest and most complex — with invitations that function as luxury objects reflecting the family's aesthetic and economic status. Letterpress has become the signature process for premium wedding stationery in India's metropolitan markets. A premium letterpress wedding invitation suite (invitation, RSVP, menu, table seating) typically costs ₹400–₹2,500 per set when letterpress-printed on heavy cotton paper, compared to ₹30–₹150 per set for standard offset-printed equivalents.
