The reality is that most output errors have to do with fonts. Font compatibility is a big prepress issue. For Inkd, you should not convert fonts/text to outlines unless you are using a font that you do not have permission to distribute. Bear in mind that Inkd buyers need to be able to customize text. Text that has been converted to outlines is no longer editable; in fact, it would have to be re-typed and styled from scratch even for a simple change. While we want to end up with visually eye-catching, distinctive designs, there are practical concerns for the buyer and the printer.
