SÜDPACK, a leading manufacturer of high-performance films and packaging solutions, has expanded the range of use for its innovative SPQ technology for flexo printing. The technology now includes rotogravure printing and offers an alternative that is not only highly efficient, but also conserves resources.

Using the technology for rotogravure printing requires the complete standardization of machine and process parameters as well as smart color management. Just like for flexo printing, all of the designs are mapped automatically in the pre-press stage using a reduced color palette.

Thanks to the PUR-based (polyurethane) color system, the ink is also suitable for pasteurization and sterilization. This opens up a wide variety of options for applications that involve heating, like ready meals, pet food or baby food. The technology is also ideal for finishing flexible films for high-quality, fast-moving consumer goods, such as coffee, tea or confectionery, because it can also incorporate metallic colors, like gold or silver, as well as coatings for texture and other finishes. The process is also suitable for imprinting Digimarc digital watermarks.

Primary focus – sustainability

Using SPQ can significantly reduce the carbon footprint of package printing. This is due to the reduction of the standard color palette from ten to just seven colors, which decreases both ink and solvent consumption. 

“With SPQ, we significantly reduce ink consumption, ink waste and the number of color changes, explained Enrico Riesel, Senior Site Director at SÜDPACK Bioggio. “Even though the color palette is reduced to seven colors, it is still possible to realize virtually the entire color spectrum as well as additional metallic colors – all while maintaining superior print quality similar that of a photo as well as excellent color brilliance.” 

In-house calculations performed by SÜDPACK have shown that limiting the palette to seven colors leads to a savings of approximately 36.5% in a typical standard process for a print order for 15 thousand running meters.

Additional factors in terms of sustainability include lower energy consumption and the reduction of film waste that would have usually been produced during the changeover of printing machines for the next print order.

Greater efficiency with real added value for customers

SÜDPACK customers benefit most particularly from the reduced amount of effort required in the pre-press stage. Using a strictly defined color space eliminates not only constant color adjustments, but also complex and costly on-site print approval. An additional advantage is that different print designs can be combined in one print order.

Impressive print quality and color brilliance

Last but not least, the new technology stands out due to its high register accuracy as well as its outstanding color consistency and color brilliance. This is thanks to consistent, smart color management along the process chain. Realistically speaking, the standardized color palette can create approximately 95% of all Pantone colors – and does so with stable, reproducible color conversion. As a result, SPQ completely eliminates all of the adjustments that had been necessary for conventional printing processes.
