Determining Label Quality

Many labels in a typical retail environment are unreadable. The following illustration shows some of the common problems. Vendors and printers regularly supply products to the market with bar codes that are over-printed, under-printed, or truncated. Some labels have missing margins. Others may be printed around the corners of packages, or on media not likely to remain flat when picked up.

The readability of a label depends on variables such as size, placement, color, paper type, ink viscosity, and package coatings. The middle of a printing run can yield erroneous labels due to the many variants involved. In particular, poor color contrast and marginal print quality can make a label hard to read.
