Due to the nature of vinyl cutting all artwork should be submitted as vectored artwork. An example of this format is an Adobe Illustrator EPS file. Bitmap files such as BMP, JPG, PSD, GIF, cannot be directly cut out of vinyl.
The graphics in these bitmap files have to be traced and converted into vectored art which can diminish the quality and/or precision of the artwork. Submitting bitmaped artwork can also increase cost/production time.
