What does it do?
The DuSense DDC-810 ‘Sensory Coater’ is a compact embellishment inkjet used to print clear UV spot varnish with the option of raised and textured finishes that resemble embossing. It can take sheets up to long B3 format (364x740mm) and register the spot coating to pre-printed images.

When was it launched and what made you to launch this product for Middle East?
The machine was discussed and previewed in the US last year, but the official in Middle East would be happen before the end of this year. The international launch will be at Ipex in October.
Alexandre Najem from Giffin Graphics, commented about the product, “There are several reasons for launching the product and some of them are listed. The product was launched to fill the gap in the constant need for faster turnaround and shorter runs, and without compromising quality. The GCC markets, and specially the UAE adopted the digital Print since few years already and there are ample of Digital Print Companies offering their services. The Market being one of the most advanced in the region is asking for special type of Digital print with various finishing (i.e. Spot varnishing, foiling ... etc) whether on Packaging or commercial print.
The DuSense comes as an answer to those needs with quite an attractive plans offered by Duplo Gulf and its Partners in the region with many advantages over its competitors at an attractive Cost per Copy.

How does it work?
It is essentially a single-colour, single-pass inkjet printer with 600dpi head arrays. It can produce variable-height effects of 20-80micron thicknesses in the same pass. This is modest compared with the Scodix (see Alternatives), which can achieve 250microns. Duplo says: “This technology enables the combination of heavy solids and fine detail in the same image, as well as smooth curves and detailing in beautiful fine lines, down to 6pt fonts.”
The artwork files can be PDF or TIFF formats, where the DuSense effect has been set up as a separate layer over the colour image and then extracted as a separate monochrome file. There are four thickness options, with texturing controlled by greyscale height mapping in the artwork.
The air suction feed and double-feed detector is based on Duplo’s existing AMS technology. Duplo points out that the long B3 sheet size could also be a B2-plus sheet cut in half lengthways. However the feeder capacity seems modest at 150mm high.
The DuSense Sensory Coating fluid is supplied in three-litre vacuum sealed bags, with easy loading. Duplo says that three litres can print over 3,500 sheets with 40micron thickness and 15% coverage.
It is compatible with pre-printed media produced on HP Indigo (ElectroInk), offset printing or anything laminated with corona-treated OPP film. The high-gloss result is said to have a gloss level of 99 (the same as Scodix’s fluid), although Duplo says it has seen up to 104 in tests. It’s possible to put clear spot gloss onto matt ‘soft touch’ laminate to give a mirror-like result on metallic films.
Duplo says that is developing other Sensory Coating fluids to deliver other types of embellishment in due course.
Self-cleaning systems avoid the need for daily manual cleaning while the printer can be switched off and left unused for up to five days, after which it can be ready to run in minutes, Duplo says.
Twin cameras and the Duplo IRM (Image Register Mark) aid alignment, with a claimed 0.2mm accuracy along the entire sheet length. There is automatic setup and adjustment for every sheet, extending from XY image shift to stretch, skew and twist that are common after laminating. This is all performed in real-time.
The built-in controller and screen are Windows based. The DuSense GUI allows other Windows-compatible software such as Acrobat and image editing programs to be run on the operator console. The software can also be installed in the pre-press department to use the integral job preparation tools, as well as for estimating.

How does it differ from previous products?
This is Duplo’s first digital spot varnishing device, although the company has sold overall UV coaters for years.

How fast/productive is it?
DuSense can run at 1,080sph (SRA3/B3). Duplo says that, for example, it could run a 600-sheet job on 250gsm media in 30 minutes with unattended operation. As the UV coating cures instantly the sheets are ready for further finishing operations right away. Duplo points out that cutter-creaser multi-finishers such as its DC-646 and DC-746 will cut without crushing the 3D effects that bleed over the edge, where a guillotine might damage them.

What’s the USP?
It is the first digital embellishment system from Duplo, although MGI and Scodix produce broadly similar systems in a range of formats, mostly at higher list prices and with higher raised effects. The DuSense is notably more compact than the others, but its maximum sheet width is less too.

Alternatives
MGI JetVarnish 3DS
Smallest of the JetVarnish range, but with the usual MGI long sheet facility and a 300mm feeder/stacker capacity. The iFoil spot metal foiling unit is optional, as is variable data imaging. This model is configured for digital print and is exclusively sold through Konica Minolta in the UK.

Scodix S75
Currently the entry level model in the Scodix range (the B3+ S52 has been dropped). It costs a lot more than the Duplo, but takes larger and thicker sheets and has a much greater maximum print thickness.
