  • Sharp text improves readability.

  • Clean trimming and finishing create a professional appearance.
  • High-resolution artwork prevents blurry or pixelated prints.

Digital Printing, Large Format Printing, and Finishing

Digital Printing London

Large Format Printing London

Large format printing London is perfect for high-impact displays, including same day poster printing London, A0 posters, A1 posters, banner printing London, roller banner printing London, and foam boards.

Professional Finishing

Finishing options such as trimming, folding, binding, lamination, and mounting can improve durability and presentation. These are especially useful for brochure printing London, menus, booklets, business cards, posters, and display boards.

Best Materials for Professional Printing

The material you choose affects how your print looks, feels, and performs. A premium business card needs a different stock from an outdoor banner or a folded leaflet.

  • Coated paper: Great for vivid colour, flyers, posters, and brochures.
  • Uncoated paper: Ideal for a natural feel and writable surfaces.
  • Thick card stock: Best for business cards, invitations, thank you cards, and appointment cards.
  • Vinyl and PVC: Suitable for outdoor banners and durable signage.
  • Foam board: Excellent for presentations, exhibitions, retail displays, and event signage.

If you are planning a campaign, combine flyers and leaflets, posters, stickers and labels, and banners for stronger local visibility.

Colour Management and CMYK Printing

Colour is one of the most important parts of professional printing. Screens usually display colour in RGB, while most printed materials use CMYK. This means colours may appear different on paper compared with your monitor.

  • Prepare artwork in CMYK where possible.
  • Use high-quality images and logos.
  • Keep brand colours consistent across all print materials.
  • Avoid relying only on screen brightness when judging colours.
  • Ask for artwork advice if colour accuracy is essential.

For accessible design and colour contrast guidance, see the GOV.UK design guidance.

Image Resolution, DPI, and File Preparation

Resolution affects how sharp your printed images look. Low-resolution files can appear blurry, especially on posters, banners, brochures, and large format prints.

  • 300 DPI: Recommended for business cards, flyers, leaflets, brochures, and most posters.
  • 150 DPI: Often suitable for large format printing viewed from a distance.
  • 72 DPI: Usually too low for professional printing.

Adobe provides a useful guide to image size and resolution. For common A-series paper sizes, the A paper sizes guide is helpful when preparing A0, A1, A2, A3, A4, and A5 artwork.
