Our prepress workflow is MAC based however we accept both MAC and PC files for print. We are able to accept PC files because EPS/TIF files are not platform specific. A MAC .tif file created in Photoshop can be opened on a PC in Photoshop and vise-versa. A PC Illustrator EPS file is easily opened on a MAC. For our PC Corel Draw files, they are prepped as EPS files and they print just fine.

The only issue that would be problematic is Fonts. To eliminate this problem we ask all our Illustrator, Corel Draw, Indesign, Freehand users to convert fonts to "outlines/curves/paths".
The three words mean the same thing. Illustrator uses "outlines". Corel uses "curves". Freehand uses "paths".

For PageMaker users we ask you to send us EPS or PageMaker files. PC PageMaker users must use standard fonts found on both MAC and PC platforms. All PageMaker files are opened in Indesign... So Mac users make sure you stuff all fonts and send all supporting TIf or EPS images including a PDF proof.

The same should be done for Quark files (stuff all your fonts and supporting images and send them to us). Make sure you use CMYK colors in your designs and not RGB colors.

Important Notes:

1. Make sure you only use CMYK colors when designing your files. Download templates where necessary. For black and white backs.. use shades of "black" only. (i.e. grayscale).

2. Make sure images are in TIF or EPS format when placing them in Quark, Pagemaker and even Illustrator. Images should be at 300dpi quality in CMYK or grayscale mode.
