Markoprint®: A Versatile Coder for PVC Pipes

PVC Pipe CodingAT Information Products offers Markoprint industrial coders for a wide range of product identification applications. Manufacturers are tossing out their legacy print technologies in favor of Markoprint to code on PVC and other plastic extrusions.  The switch from Continuous Inkjet (CIJ), for example, is an obvious choice when comparing the two print technologies head-to-head.

Print Technology - Markoprint is based on Thermal Inkjet (TIJ) using HP ½-inch print cartridges with precise ink placement on the substrate.  Conversely CIJ delivers a continuous flow of ink to the printer, which may cause problems related to ink spills and maintenance.

Speed & Print Quality – Markoprint is considered high-resolution printing at up to 600 x 600 dpi.  With speeds up to 180 meters per minute, Markoprint can keep up with pretty much any packaging machinery.  CIJ, while exceptionally fast, prints low resolution dot patterns that look antiquated by comparison.  Customers who buy PVC piping need clear print quality to ensure they have picked up the correct part.

Throw Distance – When printing on non-porous surfaces, Markoprint can easily print 5 mm away from the product while still delivering sharp, high-contrast codes.  CIJ has even farther throw distance at 8 to 10 mm.

Cleanliness – A clear advantage for Markoprint is cleanliness. Markoprint creates no mess thanks in part to its self-contained inkjet cartridge.  However, CIJ frequently uses harsh solvents and maximum ventilation is required.  Cleaning CIJ ink spills from the floor and around the printer are regular practices.

Maintenance – With Markoprint there are no costly maintenance contracts.  With each new cartridge you get a new printhead, all for less than $100.  CIJ printers require an ongoing service contract because of expected downtime and the complexity of the system.  When a CIJ printer breaks down, the cost of a new printhead is equivalent to repurchasing the entire system all over again.

Inks - Markoprint has specialized inks with fast dry time 1 to 2 seconds.  Solvent ink colors include black, red, blue, light blue, green, yellow, and white.  While CIJ has always enjoyed a wide range of inks, many are hazardous to employees who must ingest the fumes during operation.

Capital Costs – Markoprint has a compelling advantage over CIJ in terms of upfront capital costs.  When you factor in the maintenance contracts, Markoprint can cost 1/3 to 1/2 as much as CIJ over the long run.

For PVC and many other package coding applications, the clear choice is Markoprint.  Check out our industrial inkjet coders on the AT Information Products site to see the print technology in action.  We can be reached at (201) 529-0202 or via email to [email protected]
