Call us at 1-800-345-8944. Barcodes created and resized as EPS vector files to be imported into your full color label or package design. The PNG file you receive from the GS1-US after registering should not be used in your design. Contact us with your barcode info and we'll make the EPS files for you asap. EPS output is the best choice for use with Adobe Illustrator and other software that works with vector images and page layout. EPS output is not like a traditional image. Rather than being composed of a grid of colored pixels, an EPS file contains drawing instructions and measurements. A computer or printer interprets these instructions to display the image. This allows an EPS barcode to be printed at any resolution or placed inside another vector image without any inherent limitations on image quality.
