Marking Equipment

Marking equipment is often simple, but it performs a very important service for businesses. Almost every product, whether domestic or imported, bears some kind of coding and marking that reveals the manufacturer, in addition to other identifying information. Lot numbers are of particular significance in case of problems because they enable the manufacturer or a government agency to trace the product to its origins.

One of the simplest devices used for marking is the roller coder--hand roller or line roller. Like inkjet systems, however, this coder device permits printing on a wide range of surfaces, both porous and non-porous. The ink for porous substrates is glycol-based; the ink for non-porous substrates is solvent-based.

More Sophisticated Marking Equipment

Inkjet marking equipment is the most popular because it was developed before other technologies, but also because of its low cost and adaptability. The standard modular design is a big plus because it allows lay employees to replace one segment of the machine without special knowledge. It appeals to business managers and owners also because it permits them to upgrade without buying entirely new marking equipment.

Digital printing has increased in use in the last decade; its strong point is variable data printing. This technology cuts production time, permits customization of designs and text, and reduces downtime. Laser technology has entered the printing field with high expectations because of its clean, fast, highly-productive operation. It is already used for marking packages of food and other substances, and is convenient because of its small footprint and easily-positioned laser head.
