The best format for sending your files is PDF. If you don't have a PDF driver, you can download one free at www.pdf995.com; there is also a great package available for purchase at the same web address. You can also use Adobe's PDF Creator service available at http://createpdf.adobe.com/?v=AHP. When making your pdf, please use Press-Quality settings, and leave colors unchanged or "as is" if your document will print using spot colors. Add crop marks and make sure there is 1/8" bleed on all sides if your document bleeds off the edge of the sheet. Your customer service rep or one of the experts in our prepress department will assist you in determining the individual requirements of your project. Native files are accepted; however you must provide all fonts and graphics used in your document if submitting native files such as Publisher, InDesign or QuarkXpress files. A complete list of document types is available under the "ORDERS & QUOTES, UPLOAD FILES" tab. Graphics should be either vector (eps) files or high-resolution (300dpi or higher) image files (such as JPG or TIF). Low resolution files will detract from the quality of your final product, and we strongly caution against using them.
