nope, i dont think that there is.. when you make a vector image the program makes mathamatical equations for each line. Im pretty sure that there is no way to turn a JPEG into a vector image, i dont know alot about TIFFs but i found this that makes me think that you cannot.
<QUOTE>There are no provisions in TIFF for storing vector graphics, text annotation, etc (although such items could be easily constructed using TIFF extensions), and so if this is a requirement you would be better off with a format with broader scope, such as PostScript, CGM, or PICT. TIFF is based on file-offsets, so that it is not easily "streamable" in the way JPEG JFIF streams are.</QUOTE>
You may have to create the logo using vectors or get a printer that doesnt require vector formats.
