Konica Minolta makes the print engine
(including its own inkjet print heads
and controllers), inks and front-end,
while Komori provides the substrate
feed and transport mechanisms.
Komori assembles each press.
It takes oversized B2 sheets up to
585x750mm, allowing six-up A4s on a
New 600dpi printheads with piezo
shear technology are fitted in pairs to
give 1,200dpi. There are eight pairs per
full-width print bar and one print bar
per colour. Initially, the presses will be
wide-gamut CMYK, with five and six
colour options in future.
Inline sensors detect misfires and
correct on the fly. The head carriage
retracts sideways for maintenance and
heads can be replaced by the operator.
The most unusual aspect is the
UV-cured ink. This was specially
developed for the KM-1 and is heated to
reduce viscosity, allowing very thin ink
films. The LED curing lamps are
compact and cool, though a simple fan
extractor and duct is required, largely
because of the heated inks.
How fast is it?
Production presses will print 3,000
simplex or 1,500 duplex B2 sheets per
hour at up to 1,200dpi, with full
variable print. This is a little slower
than the 3,300sph originally
announced. Konica Minolta says this
was needed to achieve the desired feed
reliability. There are three printing
modes, with the same resolution but
different ink drop sizes, which helps
reduce ink consumption depending on
How does it differ from previous
This is a brand new 'clean-sheet' press
design, although it builds on Konica's
experience with its bizhub Pro presses
and its top selling Nassenger SP-1
textile inkjet, plus Komori's media
What's the USP?
According to Konica this is a 'UV inkjet
that has offset quality, look and feel,
with the benefits of digital printing'.
How easy is it to use?
Control is largely through Konica
Minolta's digital front-end, which it
calls the Inkjet Manager. There will be
two performance options, with the
more expensive Pro being for full-speed
variable data, and the Light type being
for less demanding content. Sheet
loading and unloading is similar to an
Konica Minolta will offer full service
and support contracts, plus operator
training, and will provide as its Digital
1234 business development services
with the press.
What does it cost?
Konica isn't revealing prices until
drupa, but previous predictions from
the UK are in the £1.2m to £1.3m range
(ballpark around the A$2.5m marker at
today's dismal exchange rate) There is
likely to be a combined per-copy charge
with consumables sold separately. UV
inks tend to be expensive, though far
lower volumes are needed than aqueous
inkjet inks as there is no significant
evaporation. Konica is predicting
significantly lower costs-per-copy than
toner presses, allowing the KM-1 to be
more competitive against offset on
How many are installed?
So far there are three beta presses, in
Japan and the US, and the first
European site was due to start up at the
end of January.
When can I see it?
Visitors to drupa will see the launch of
the press during the eleven days of the
show which begins at the end of May.
This Memjet based aqueous
inkjet press has an unusual
SRA2 sheet size but its price of
around A$900,000 is well under
half that of rival inkjets, while
beating them all on speed.

FUJIFILM JET PRESS 720S
Revamped version launched in
2014, with a handful of
installations. It remains simplex
but now has facilities for data

HP INDIGO 10000
The only B2 digital sheetfed

compatibility with a lot of
substrates. Up to three paper
drawers can be used.
