A service bureau is a business that specialises in producing high-quality output from digital files using professional devices such as laser imagesetters, film recorders, large-format plotters, and other specialised equipment.
Photographers, designers, and printing professionals often use service bureaus to convert digital artwork or photographs into print-ready formats, transparencies, or high-resolution large-format images. These bureaus provide expertise and access to equipment that may be too expensive or specialised for individual use, ensuring precise, professional results for commercial and artistic projects.
