PDF stands for Adobe® Portable Document Format, and are produced by Adobe. PDF files protect the originality of files and are more legible than HTML files. Moreover, since they have a defined structure, PDF files are clean and easy to print. Any machine with Acrobat Reader or Adobe installed on it can read PDF files. We currently prepare all our e-proofs in the PDF format and they are best viewed in Acrobat Reader version 7.0. * Some PDF format files can be accepted as artwork, contact the art department for details.
