This document provides guidelines for designing binary codes to be printed on pharmaceutical packaging materials like cartons, leaflets, labels, tubes, and blister foils. It describes recommended code dimensions, positioning, minimum number of bars, and use of color. Codes should contain thick and thin bars and use color combinations that avoid missing color errors. Guidelines aim to make codes easy to design, print, read, and secure against mix-ups, while accommodating various packaging types and printing/cutting tolerances.
