We prefer to receive logo art in EPS format and in Black and White, typically. That is best for a monochrome (single color) logo, regardless of the ultimate color of your logo. If you would order a logo in multiple colors, we would need to know the PMS (Pantone) colors of the final art.
If EPS format is not possible, we can work with a JPG, JPEG file if it is in high resolution. If there is some doubt or concern about the logo, please phone us at 866.748.2230.
