HP Indigo 30000 can print on even thicker paperboard

HP Indigo 30000 digital presses can be modified to print on substrates with a thickness of 660 microns.

The HP Indigo 30000 can originally take substrates that are up to 600 microns thick. In a development project run by Green Gift Cards, HP Indigo, Transcend Packaging and Iggesund Paperboard, that thickness has now been raised to 660 microns. This is a significant jump up taking into account the stiffness and bulkiness of the Invercote board that is going through the print system.

Produced by Iggesund Paperboard, Invercote is a sustainable multi-layered paperboard substrate made from chemical pulp.

“Being able to print digitally on thicker materials is an important step in producing gift and other types of cards on digital presses,” said Graham Lycett, Managing Director of Green Gift Cards, who has been one of the driving forces behind a development project to increase the thickness of paperboard that can be used in an HP Indigo 30000.

“It is a huge jump, 10% makes all of the difference between paper-jam galore and a smooth print operation. Not to mention scratches, etc. Besides, this is only half the story – media stiffness is the real issue we needed to address. Invercote is almost like plywoo very stiff and doesn’t easily bend in the system,” said Moshiko Levhar, Business Manager, Folding Cartons, HP Indigo.

“This brings us far closer to the haptic – the feeling of the card in the hand – sensation of a traditional, plastic gift card in credit-card size. This is important, since some companies hesitate to change from plastic to paperboard for that very reason,” Lycett added.

Lycett is an advocate for replacing plastic cards with paperboard ones. Making the change can reduce the cards’ environmental impact by over 95%, as a biogenous rather than a fossil-based material is used.

Currently, only one printing press is modified to take the higher thicknesses. It can be found at Transcend Packaging in the UK, a company which is also passionate about reducing climate impact. As well as producing packaging and cards for Green Gift Cards, Transcend Packaging is also known for high-volume production of paper-based drinking straws.

HP Indigo’s involvement in the project also brings other benefits since it means that HP’s Mosaic software for variable printing can be used.

“Not only can we vary the print from one card to the next; the digital printing also means we can offer reasonably priced cards in smaller print runs, while large organisations can order card volumes to fit consumption, rather than printing massive runs to get the best economy. They change to a renewable material and their orders reduce the need to keep stock, while also reducing waste and allowing scope for quick design modifications,” said Lycett.

The development of HP Indigo’s printing presses is largely based on the qualities offered by Iggesund Paperboard: “We have actively worked to ensure our Invercote paperboard is the best option for digital printing. This project confirms that we’re on the right track,” said Thomas Janson, Business Development Manager at Iggesund Paperboard.
