The perfect mix

Whether printing on pressure-sensitive labels, clear film, cartonboard or any other packaging substrate, the performance and characteristics of the ink used are an integral part of the production process. 

From printing and post-press processing to the application and ambient environment, there are a number of factors that converters must consider when making their ink selection. Suppliers must similarly be aware of these factors when developing new ink formulations...

HP’s developments focus on ElectroInk to work with its liquid electrophotography (LEP) technology. HP ElectroInk contains charged pigmented particles in a liquid carrier, combining the advantages of electronic printing with the qualities of liquid ink. On-press, ElectroInk is supplied as a concentrated paste that is loaded into the press in tubular cartridges in a ‘clean hands’ operation. Inside the press it is fed into ink supply tanks and diluted with oil, to form a fluid mixture of carrier liquid and colorant particles ready for printing.

This core formula is replicated across the ElectroInk portfolio, regardless of ink type or application. Thanks to this, the characteristics of the ink are not dependent on the pigment and the behavior through the printing process remains similar across all inks...

US-based Innovative Labeling Solutions (ILS) beta-tested HP Indigo ElectroInk Silver and is now offering the ink to its brands. ‘Eye-catching metallic designs can be achieved while maintaining the benefits of digital printing, including easily and cost effectively changing the metallic effect from version to version,’ says Kristen Waite, marketing communications manager at ILS.

ILS is printing silver ink on clear BOPP and its customers are finding it to be a viable, economical alternative to using a hot stamp when trying to achieve custom metallic designs for different versions and label sizes in a product line. Waite adds: ‘By using silver ink, they avoided the upfront tooling costs they would have incurred for each design and each label size.’
