Supported software applications for poster graphics include QuarkXpress, InDesign CS, Photoshop CS, Illustrator CS and of course Adobe PDF documents. Powerpoint users may find the FAQ helpful for setting up a custom page in Powerpoint to produce a poster. Microsoft Powerpoint, Word and Excel users should save their files as a PDF to ensure fonts and images print correctly. We can scale your PDF file to any poster size, e.g. create an A4 document and we can output your poster to A1 size.

Image files should be at least 75 dpi @ 100% of the final output size or 100 dpi @ 75% of the final output size or 300 dpi @ 25% of the final output size.
Anywhere you use black, define it as cyan=20%, magenta=20%, yellow=20%, black=100%
Use Pantone "solid to process" guide for PMS references supplied for colour matching.
In Photoshop please flatten all images and don't use extra channels. Convert all duotone and RGB images to CMYK. Save all images as EPS (encoding JPEG Maximum quality).
Any language fonts other than English should be converted to outlines. "Select all" in Illustrator & Freehand and set attributes to 9600 dpi. Please be sure to include both screen and printer (PostScript) versions of the fonts used in both the document and in any EPS files supplied in case changes are necessary. These are found in the system/fonts folder on your Mac or in the Windows/system folder on your PC.
Be sure to include all source files, graphics and fonts with your job. Use prepress packaging commands such as "Collect for Output" (Quark 5.0 upwards), this collects all linked images, logos and fonts into one folder.
Important - For best results, please provide a PDF or printed colour proof with your files as various colour output devices interpret colour differently.
If using a compression program, take your file(s) and compress them into one .zip, .sit or .sea file. If you don't have a compression program or need instructions to compress your file(s), you may download a free version from: Stuffit or WinZip.
