A new range of coatings including overprint varnishes and adhesives
specially formulated for use in digital devices is set to be launched in
the next few weeks.
Marcos Valdezate, Sun Chemical’s business
development manager for coatings for digital applications, said: “We
recognise that some transformation of the packaging industry as we know
it today in terms of printing, is already starting to happen. Some large
converters have already started looking into digital processes so the
aim of this agreement is to facilitate that transition by enabling
“Our intention is to ensure that the
printers and converters can deliver the performance required by the
brand owners to packaging specification and industry standards – that
the inks are staying on the surface and wedding properly to the
substrates with the appropriate resistance, effects and desired
Valdezate said that HP Indigo had already invested a
great deal of time and resources upgrading print processes and workflows
that would facilitate packaging applications, so the work by Sun
Chemical in developing coatings and adhesives is one of the key enablers
to making digital packaging production a reality.
He said Sun Chemical has been working with HP Indigo for a while
and already provides a limited range of adhesives for use on its
machines, but wants to build on those with an expanded range of products
adding new functionalities.
“We shall soon be releasing a
digital coating portfolio under a unified Sun Chemical corporate
identity to ensure HP Indigo customers have access to a proven track
record of added-value solutions, regardless of their geographical
location,” Valdezate said.
As well as working with press
engineers at HP, Sun has also been working closely with printers,
converters and brand owners to identify their needs and ensure that the
new range of coatings meets the requirements throughout the value chain.
will be a significant way forward,” Valdezate said. “One of the big
advantages of digital printing is it gives you the ability to
personalise each print, and we know that is important for brand owners
as it unleashes new possibilities to communicate with end-users, hence
making packaging more meaningful.”
He said this has been proven
in different campaigns like KitKat and Coca-Cola, but the challenge for
the industry is to establish digital as a “true cost-effective
HP Indigo currently offers three digital presses for
packaging applications ranging from labels and shrink sleeves to

printing solution for labels and packaging production, and the HP Indigo
WS6800 is another narrow-web press which incorporates the HP Indigo
