Smaller World (Bar Code Inspection)

Before converters can verify, however, they've got to get these little codes down on the substrate first. "The biggest pitfall with most of these new codes is that they are smaller and denser, and therefore leave less room for error," points out Elizabeth Urvan, senior sales consultant, Stratix. "Some printing challenges will include ink gain/loss, missing sections of the bar code, and overall uniformity in the image of the bar code. In some cases converters may have to print more slowly then they could to produce standard linear bar codes."
