Both an automated flatbed inkjet and a low-cost sheetfed B1 press.

What does the product do?
This is a UK-built sheetfed B1 printer using multi-pass inkjet and UV-cured inks, capable of printing up to 200 full-sized sheets per hour. It is essentially a flatbed printer with a sheet feeder, through-transport and stacking system. It will be distributed globally by both Inca and Fujifilm, which already distributes other Inca Onsets. 
Their product manager Paul Baker says it is a “direct result of customer feedback and their desire for a B1 press that is capable of printing short runs, on-demand and on a wide variety of substrates”.

Specifications
Process: Sheetfed inkjet with UV-cured inks
Printheads: Fujifilm Dimatix piezo-electric
Min drop size: 7pl

Max speed: 120sph
Sheet sizes: From 530x380mm to 1,050x750mm
Print size: Up to 1,040x714mm
Substrate thickness: 0.1-10mm

What market is it aimed at?
Initially the primary use is seen as display boards and similar POS applications, though it also can handle thin paper or heavier sheet materials up to 10mm thick.
Baker says, “The productivity and quality of the new platform will give commercial and screen printers the confidence to take lower-volume work off presses, increasing overall productivity and opening up potential new revenue streams in the process.
“However, its inherent versatility means that it will also be suitable for an extensive range of applications, including substrates that are too thick to be printed on offset.”

How does it work?
The printer uses new Fujifilm Dimatix small-drop, 7pl binary piezo heads, which Inca won’t identify exactly but says allow “crisp 4pt text and smooth colours, ideal for short viewing distances”. It also uses “next-generation optical printhead alignment and calibration systems”.
There are eight ink channels, allowing the user to choose either dual-CMYK for higher speeds, or CMYK plus light cyan, magenta and opaque white.
Sheets are automatically taken from a feeder and loaded onto a fixed vacuum table inside the main print unit. A zoned vacuum system copes with different sheet sizes with no need for edge taping. The head array prints in scanning mode across the sheet, with UV-LED lamps then triggering an initial ‘pinning’ part cure, which stops the ink running or being absorbed too much into the substrate.
The sheets are then passed to a separate UV curing tunnel unit for the final cure by more powerful mercury lamps, before being passed to a stacker. This two-stage curing allows thin or heat-sensitive materials to be handled without distortion.
Manual and “three-quarter automation” versions are also planned, with a modular lay table and collection tray to suit customer requirements and budget.
Onset M shares some technology with the established Onset X series of moving-bed flatbeds, including the print array (though not the printheads), nozzle mapping (to compensate for blockages), automated printhead cleaning and a collision avoidance system.
Inca’s more conventional Spyder X has a fixed bed, but Baker says that Onset M has more in common with Onset X.

What is the USP?
Baker says there are several USPs. These include, “Full-width print array scanning system for B1 format, providing high-quality print – a viable option for taking shorter runs off offset presses; fully automated system with the versatility to print a wide range of material types and thicknesses – providing customers with opportunities to open up new revenue streams; and a competitive price point for an automated B1 format system, that enables a wider range of potential users to adopt inkjet.”

How easy is it to use?
“It is fully automated, although there will be three-quarter and manual material handling options,” says Baker. The user interface is said to be simple to use. There is automatic printhead cleaning for easy maintenance.
The IncaConnect software suite also allows integration and customisation to existing workflows.

What training and support is on offer?
“As with all Inca products, operator and engineer training courses will be available, either at customer sites, or in our Training Centre in Cambridge,” says Baker.

Alternatives
Heidelberg Primefire 106 inkjet  & Landa S10
Inca says there are no direct alternatives, presumably meaning at the planned price point, though it won’t yet say what that is. There are other B1 sheetfed digital presses, including the Heidelberg Primefire 106 inkjet (developed in cooperation with Fujifilm and using water-based inks, for up to 2,500sph).
And the Landa S10 Nanographic offset inkjet (which has reached its first user site in recent months, offering 6,500sph on paper or plastic-based substrates with the intention of increasing this to 13,000sph eventually).

MGI’s Alphajet B1-plus
MGI’s Alphajet B1-plus single-pass UV-cure inkjet was shown as a prototype at Drupa 2016. This is broadly similar in concept to the Onset M, with a versatile feeder able to take a wide range of media up to 750x1,200mm.
