Context
Posters are large-format printed sheets designed for display, advertising, decoration, or information purposes. Standard sizes range from A3 (297 x 420 mm) through A2, A1, and A0 (841 x 1189 mm), with custom dimensions available for specific applications. Posters are produced on paper stocks from 135 gsm uncoated to 250 gsm silk or gloss, depending on whether the end use is temporary event promotion or long-term display. Production methods include digital printing for short runs, offset lithography for quantities above 1,000, and large-format inkjet for oversized or photo-quality output.
Common Specifications
Poster printing supports a wide range of substrates and finishes. Standard paper posters use 170 to 200 gsm silk or gloss stock for vibrant color reproduction and sharp detail. For outdoor or high-durability applications, posters are printed on waterproof synthetic substrates or encapsulated with protective lamination. Mounting options include foam board, Gatorboard, and aluminium composite panels for rigid display. Files should be supplied in CMYK at 300 dpi for sizes up to A2, while larger formats can accept 150 dpi due to increased viewing distance. Bleed of 3 to 5 mm is standard depending on the printer. Common finishing options include matt or gloss lamination, canvas texture overlays, and tube rolling for shipping.
Web to Print Context
Posters are a strong performer across both B2C and B2B web to print channels. Consumer platforms offer photo poster creation with drag-and-drop editors, filters, and layout templates that make poster design accessible to non-designers. Business-focused platforms provide event and retail poster templates that marketing teams can customize with location-specific details, pricing, or promotional messaging. Online configurators handle size selection, paper stock, finish, and mounting options with real-time pricing updates. Automated artwork checks verify resolution and bleed before production, reducing reprints and returns. Poster products benefit from straightforward imposition, making them efficient to gang on digital or wide-format devices.
