Common Problems Manufacturers Encounter With Barcode Printing

At Markem-Imaje, we know that barcode printing requires absolute precision; this is just one reason manufacturers must choose equipment and service providers that are highly trusted and reputable. As one of the most trusted providers of coding and marking systems around the world, we understand some of the problems encountered during barcode printing. Some of the issues we have seen occur include: Dead spots. What causes these "gaps" or dead spots on your barcodes? Most likely wrinkling of the ribbon on the printer. Try resetting to see if this solves the problem. Unusual growth in bars. If your ribbon is worn or old, or if you are using a printer speed higher than required, you may experience unusual growth or expansion in the bars. Check the ribbon, and ensure that you aren't running the printer at too high a speed to resolve the issue. Image is too light or insufficient PCS. Do you find your barcode images are too light or faded looking, not as dark as you would like them? It could be an issue of overheating of the printer head, or a sign that it's time for a fresh protective laminated stock. Faded or too-light barcodes can also indicate that the ribbon and media are incompatible. If you suspect overheating of the printer head, slow down the printing speed, as a higher speed produces more heat. Irregular narrow-wide ratio. There are several potential causes for this, including insufficient ribbon transfer. If you suspect this to be the cause of an improper ratio, raise the energy setting and use a compatible ribbon that matches the level of sensitivity. Another cause of irregular ratio is excessive ribbon transfer, also referred to as over-burn. In this case, you would do the opposite by lowering energy settings and switching to a compatible low sensitivity ribbon. When bars on barcodes appear to be too thick, it may be necessary to reduce energy settings; also consider the quality of the ribbon. Markem-Imaje is a global leader in industrial printing solutions, offering manufacturers a wide array of solutions for product, case, and pallet coding, as well as traceability software, fluids, inks, and ribbons.
