The method is especially suited to brief runs: “There isn’t any overproduction, you solely print as many designs as crucial,” stated Mr Melichar.
Enterprise sectors utilizing digital printing most successfully are meals and beverage packaging, fast-moving shopper items equivalent to cosmetics and prescription drugs and, significantly for the reason that Covid-19 pandemic, e-commerce, when on-line promoting and deliveries boomed, stated Schavoir.

Value has all the time been the primary sticking level as a result of worth of the tools and ink wanted. And specialists agree that analogue printing – flexo or lithography – continues to be extra economical for bigger print runs: “Digital printing continues to be sluggish in comparison with standard printing,” Melichar stated. “However digital catches up by way of pace and value,” particularly with points round plates and tooling.

The corporate launched a contest the place if two folks discovered the identical Nutella jar, “they received large cash. This created an enormous buzz with folks utilizing social media to advertise their packaging and discover the dual.”
Digital printing additionally means sensible packaging, added Melichar. Tamper-proof options are potential with serial numbers and bar codes. On this method, digital printing will help battle counterfeit packaging, he made clear.
Maybe the clearest profit is in digital printing’s sustainability. “There aren’t any instruments and no plates,” stated Schavoir and Melichar, which means that the CO2 footprint is significantly better. Power, time and assets are saved.
There isn’t any materials and paper waste as a consequence of customised manufacturing and on-demand printing. As well as, eco-friendly inks, soy or water-based colors and recycled supplies can be utilized.
Whereas digital printing is making waves in all supplies and sectors, and the expertise is changing into faster and with an improved format, there’s doubtless room for each strategies: “Digital printing is complementary to traditional printing,” stated Melichar.
