We prefer native files accompanied by High-Resolution Press Ready PDF(s) with 1/8” bleed/safety and trim marks. When supplying native files e.g. Adobe InDesign®, please include all elements; documents, images, and fonts. Place in one folder and zip or compress before attaching or uploading. PDF files are the standard format for transmitting files for printing, but it's important to prepare your PDF file correctly. Improperly prepared files can delay your job and result in additional charges. Feel free to call or email us with any questions.
