Any non-photographic content (including graphics and text) should be uploaded as vector-based files in order to ensure that lines are crisp and clear. Some content, such as logos, typically needs to be separated from the background so that it can be resized or otherwise manipulated for better print results. Vector images offer the most flexibility for these purposes. Supported file formats currently include Ai, CDR, PSD and pdf. If you have any questions with regards to file preparation, please feel free to contact your account representative.
