ink technology along with their potential issues.
Professor Dr. Em. Marc Van Parys expressed
his opinion that pigment still faces considerable
challenges over wet processes as wet process colours
become an integral part of the fabric as opposed to
pigment binding onto the fabric.
The next presentation came after a welcomed
coffee break where I had the opportunity to get to
know other delegates and hear their impressions
of the proceedings so far. Michael Nothelfer from
Caddon provided a technical presentation where
he explained the difference between spot reading
spectrophotmeters and multispectral measurement
using the Caddon Can:scan multispectral device.
The key benefit is that the equipment is better
engineered to handle textured surfaces in carpet,
velvet and other course fabrics since it can scan
each surface by creating 16 images through 16 filters
without making direct contact with the surface under
a D65 or D50 light source.
It can scan up to 1000 x 600mm in size and has a
measurement accuracy of 0.1 ΔE. The investment
is approximately €75,000 depending on the
options selected. When compared to an X-Rite
i1Pro2 which is perfect for smooth flat surfaces,
the multispectral system covers all surfaces up
to 50mm thick. This technology offers the highest
quality colour acquisition and ICC profiling
capability for industry segments such as carpet,
laminate flooring, and leather.
Once again, I moved back to the creative side to
listen to Dr. Arnaldo Cacaci from Digital Media
Großbildtechnik. His presentation was called ‘Large
Format Printing 3.0: Find your niche, adopt new
skills or become redundant’.
Next, there was a discussion about wall coverings
and the critical performance characteristics that
are necessary such as abrasion resistance, tear
resistance and image resolution. Arnaldo talked
about one project where the tenant wanted an
exposed concrete finish to cover 4,000 square
metres of wall space. As the tenant didn’t own the
building, a temporary wall covering was created by
photographing concrete and printing the wallpaper.
The client was completely fooled. The clear message
from Arnaldo’s experience was that there are great
opportunities available to those who focus on
creating best in class products and marketing them
to a clearly identified customer group.
Meanwhile back on the technical side, Dr. Veena
Sarojiniamma from Industrial Inkjet talked to us
about the quality criteria required in wallpaper
applications and the differences between screen
printing, flexo, rotary screen, gravure, hand blocked
and of course their interest, single pass inkjet.
She explained that the market size according to
Strategyr.com for wall coverings is expected to reach
$36.6 billion by 2022. East Asia is the largest with a
predicted volume of 345 million rolls.
Industrial Inkjet Limited (IIJ) are the business
unit within Konica Minolta who have developed a
single pass technology using water-based pigment
inks that can run at 2,300 linear metres per hour.
This printing system provides the opportunity
to print at industrial volumes and enables the
process to disrupt the market that has previously
been an analogue space.
Dr. Sarojiniamma went into great detail about the
need for automatic maintenance, print durability
Arnaldo explained their journey in becoming
a leading global architectural glass printing
specialist. He discussed the value in getting
into the project management cycle early in
printed interior décor so that the designer or
architect understands the technical performance
capabilities. The company runs an interior fitting
service for their digitally printed glass. We were
shown many examples of hotel groups who had
used their PrintProtectionTM product to image
hundreds of bathrooms. There is only one side of
the glass that is manufactured to be printable.
The value is derived from knowing what the glass
will withstand and building an independently
validated specification around it.
