Your logo kit would include the original vector source file created in Adobe Illustrator (AI), a PDF that's also vector, as well as raster JPEGs and/or PNGs that you can place in Word Docs, emails, website listings, etc.. They would come in 3 folders... CMYK (for print), RGB (for web or TV),andflat black/white for things like a 1 color imprints on specialty items. You may also want a two-color version using the Pantone Matching System that all printers go by for color matching (also known as spot colors) in case you ever need it reproduced in just two colors rather than all of them.
