What happens when there are no fonts.
When artwork is created they are done with fonts that are installed on your local computer. If the font is a standard one like Arial this is usually not a problem. An issue can arise however when the font is non standard and it does not exist on another computer. In this instance the computer without a font is unable to read the font correctly and the artwork will not resemble the original document.
What should I do to avoid problems?
The ideal way to get round problems with fonts is to make them part of your original document through embedding them, flattening them or converting them to curves.
Saving as an image By saving the file into a raster format i.e. jpeg, png, tiff etc the fonts become part of the image.
Embedding fonts into the artwork
This is dependent on font licensing and is normally used for PDF files. Some programmes prompt the user if they would like to embed the fonts into document. If you select yes this will package the fonts into the document and will open successfully on another computer.
