REQUEST INFORMATION ABOUT oneECG
oneECG is BOBST’s Extended Color Gamut (ECG) technology deployed across analogue and digital printing processes in label, flexible packaging, folding carton and corrugated board industries. It enables to achieve color consistency in a stable, repeatable and consistent way irrespective of operator’s skill.
What is ECG?
Extended Color Gamut printing (ECG) refers to a set of inks - 4 and beyond, but typically 7 - CMYK + Orange, Green, Violet - to achieve a color gamut larger than the traditional CMYK and it avoids using spot colors. oneECG is the full digital automation of ECG across BOBST printing processes.
Why ECG?
Brand owners and consumers perceive color variations as a lack of product quality, heavily affecting brand identity and customer loyalty. Brand’s colors should be consistent irrespective of the printing process, the substrate, and the country where production is done. Furthermore, color matching of PMS Pantone colors is often left to the ability of operators to mix the inks, adapt to the different substrates and other subjective elements. This strong component of the operator’s skill cannot ensure perfect reproduction and repeatable consistency of the brand colors.
Thanks to the diffused knowledge of ECG and color management, BOBST is a preferred partner for converters looking for “cross” packaging applications, on multiple substrates, with accurate color matching requirements.
oneECG offers end-to-end solutions developed in collaboration with leading industry partners from pre-press to the printed and converted substrates. It is only the seamless integration of all elements that concur to an end-to-end process, from the design file through to inks, printing, converting and the final product that enable to exploit at best the powerful potential of ECG printing, eliminating the risk of producing color defective substrates. BOBST oneECG solutions are tailored to the requirements of each type of printing technology to ensure the successful and efficient implementation of the Extended Color Gamut process.
oneECG for gravure printing presses is developed for Extended Color Gamut printing using solvent-based and water-based inks to achieve the highest color stability, repeatability and print consistency worldwide. Having achieved outstanding color performances in oneECG in gravure, BOBST has the expertise and technology for ECG-ready printing presses, whether it be a new press or a retrofit package, and can guide converters on how to deploy oneECG in gravure printing in their own facility. To assure the highest industry standards, oneECG in gravure works in collaboration with multiple leading suppliers along the entire ECG workflow in a high level open-partnership system.
Exceptional Color Consistency
Color matching means no more manual ink formulation, mixing in the ink kitchen or on press color adjustments.
Color matching is digital therefore avoiding the need for ink adjustment on the machine.
Color Delta E is repeatable, measurable, consistent, and independent from the press operators.
Vibrant & realistic high quality graphics and photo images
In addition to CMYK, the addition of Green, Orange and Violet images offers deeper and more natural colors answering the most demanding job requirements and matching a wider color gamut.
Process consistency and repeatability
oneECG, in combination with the digital automation features of BOBST CI flexo presses, like smartGPS, brings significant advantages in terms of machine uptime, flexibility and repeatability. Color conformity of the printed output with the job master file is a reality, guaranteeing brand owners color consistency and repeatability of print quality for job reprints even across different production sites.
Printing efficiency
Increased printing efficiency, even for shorter print runs.
Possibility print multiple jobs in the same print run.
On-the-fly job changeovers performed at production speed.
High sustainability in flexible packaging applications
The combined action of TAPS and advanced register setting system and oneECG enables fast changeovers with minimum waste at make-ready and changeovers.
No more than the equivalent of 1.3 machine web length of substrate waste is generated at each new job set-up and changeover.
No ink waste, less ink consumption.
No color change, no washing of print units at job changeovers.
No solvent waste.
Less energy consumption as there is no longer the need of higher dryer capacity mid-machine to dry single solid coated pantone color
