Most print shops prefer a .PDF (Portable Document File) format; it will embed a copy of your fonts and images into your file and doesn’t lose the formatting, unlike Microsoft Publisher or Word which are version-dependent. You should also save your file as a high-resolution (at least 300 dpi – dots per inch) four-color .JPG file. Either format can be emailed or uploaded to the printshop of your choice. We recommend you DO NOT send original files to any print shop unless it is absolutely necessary. The person who has the original files has the rights to edit all aspects of your project; be absolutely certain of the person to whom you allow this privilege.
NOTE: If you’re purchasing vacancy window graphics, the print shop will have different requirements for both color and resolution.
