When do we need to make files cross platform compatible?
The short answer is ... when you have to move files between, or view files on, PCs and Macs, such as when you make a web site.

What are the primary cross platform issues?
There are several issues that you need to be aware of when making cross platform files.
ISO 9660 standard
The ISO9660 standard defines the file structure of a cross platform CDROM (PC and Mac).

PC & Mac gamma differencies
Gamma is to do with screens and effects the way that computers display colour. For example ...
- An image created on a PC will appear lighter and "washed out" on a Mac.
- An image created on a Mac will appear darker and with "richer" colours on a PC.
Most computer users have a range of fonts installed but they don't all have the same fonts. This can change the way that your files (such as web pages and Word docs) appear when moved between computers.
To get around this problem you can do several things ...
- Include fonts on a CDROM or a web site which a user must install on their system. BAD IDEA! Illegal and they probably won't bother.
- Use fonts common to Macs and PCs such as Arial, Times, Courier and Verdana. Good idea but limits your designs.
- Embed fonts in media files such as PDFs, images, Flash and Shockwave files. Click here for advice on this issue.
