My online printer is concerned I that I not use a Live Font. I'm just not sure what that is. I see references to Apple, but I am on a PC. I'm still looking for a definition, but found this site. Can anyone help on this?
I'm pretty sure this means the internet-based printing company you're using doesn't want the artwork you send them to include text set as fonts. They want you to convert it to shapes so that no fonts are required to print the artwork as designed on their print device.
Exactly how this is achieved depends on the applications you are using. It'll probably be a menu option similar to "Convert Text Selection to Outlines".
This means you can't edit the text any more, so you'd want to make this change to a copy of your final artwork!
What they are saying is they want you to convert the text to outlines. This is easily done in Adobe Illustrator and Adobe InDesign. You just need to make a duplicate Artboard or Page or File so you can maintain the live type (editable type) if you need to make updates later for whatever reason.
They want the text done as outlines (vector shapes) so that if they don't have the font on file or it becomes corrupted or doesn't process, that your document could still look exactly as intended.
When you say online printer, I presume you mean a publishing house such as onlineprints.com, mimeo.com, or vistaprint.com.
A live font is one that is interpolated by software and allows a single font to fill many roles. See this article by Andrew Jonhson about Live Font Interpolation on the Web at alistapart.com, which is way to long in it's explanation to capture here.
Your online printer probably wants you to avoid a live font to ensure that the materials you are submitting for print will be generated exactly as you specify.
