Kodak has developed a new imprinting solution, Prosper Plus, which is targeted at the packaging industry for applications such as folding cartons, food wraps, paper cups and plates, and ream wraps. This is based on Kodak’s existing Stream continuous inkjet technology.
The Prosper Plus units feature new print modes with smaller drop size and higher resolution for faster drying and better quality.
There are four imprinting modules to choose from. Two of these are based on a single jetting module with a print width of 105mm. They’re mainly meant for imprinting barcodes, QR codes, promotional contest information or small format designs in either monochrome or four-color output.
There are also two wider units, with two jetting modules stitched together for a print width of 210mm and aimed at corrugated, folding carton and label packaging applications. In both the narrow and wider modules there’s a choice of speeds, up to 260 mpm (850 fpm) or 600 mpm (2000 fpm) maximum.
These components are capable of being mounted in-line with offset, flexo, or gravure presses but could equally be implemented in finishing lines such as folding/gluing systems.
In addition, the Prosper Plus offering also includes food safe packaging inks and pre-coatings. The water-based inks have passed US and European certifications for food safety, direct skin contact, and food service products.
The Digital Varnish is water-based and odourless and should give converters a combination of gloss and durability enhancement on folding cartons and related applications. It’s formulated for indirect food contact compliance and is free of VOCs, mineral oils, and any unreacted UV-curable components.
Kodak has said that it is working with companies such as Michelman to test compatibility of its inks and technologies with various substrates such as PET, Nylon and polypropylene. Indeed, Kodak has worked to pre-qualify existing flexible packaging solutions from key leading suppliers to assure the compatibility with commercially available adhesives, substrates, primer, Kodak’s inkjet inks, and flexo overvarnish and overprint.
Kodak has also said that Uteco’s Sapphire Evo press will be able to take advantage of this work with solutions both for surface printing and reverse printing with lamination to produce short, medium or long run digital flexible packaging.
Randy Vandagriff, president of Kodak’s Enterprise Inkjet Systems Division, noted: “The packaging market demands innovative, sustainable, productive solutions. Kodak’s water-based inks provide the lowest cost, the highest versatility and the most environmentally friendly option for production inkjet printing. Brands and creative agencies are now able to make printed packaging a physical touchpoint to digitally connect with consumers, unleashing creative flexibility with color palettes and substrates along with operational efficiency to get to the market faster.”
The new Prosper Plus Components will be available beginning in April 2019.
