It is usually best to send a PDF file to avoid any font and formatting issues. Saving a file as a jpeg reduces the file size and can affect the quality. When sending design files, please also send any fonts and links used. Always double check your file before sending and request a proof before printing.
Resolution You may be using photos and images that come from a variety of sources, such as a digital camera, scanner or the web. Any image you plan to use should be saved at approximately 300-dpi at 100% output size for the very best printing results. Images found on the web are typically at a resolution of 72-dpi. This resolution is much to low for quality printing. In addition, most images on the web are protected by copyright laws. For these reasons, we do not recommend the use of images found on the web.
CMYK vs. RGB CMYK (Cyan, Magenta, Yellow and Black) are the colours used in the printing process. RGB (Red, Green and Blue) are the colours used by screen displays such as your monitor. JPEG files are almost always in RGB. Your document should be created in CMYK mode so that the colours that you see on the screen most closely match the final printed product. If you create your document in RGB, the colours in your printed product may vary slightly. Many of the bright values produced by your monitor cannot be reproduced in print.
Designing for Folds When designing your file, keep in mind where the fold will take place on such products as brochures, booklets, etc. If you don’t want your design to be printed over the fold, make sure it stays within each panel’s safe margin. Use minimal ink coverage at the fold as cracking may occur with heavy ink coverage.
