Big has had its day. From cars, to computers, to mobile phones, the
message is that good things really do come in small packages as people
begin to realise that size bears no relation to quality. Being compact
is now seen as a desirable commodity as technology enables us to produce
an ever greater output - but with minimal input.
Think back to
your first computer, video player or music centre: they seem almost like
outsized comedy props in comparison to their sleek 21st century
equivalents. However, these compact shells contain a powerful technology
that we could only dream of a decade ago - with the added advantage of
costing a fraction of the price by today's standards.
So, the
computing power that first propelled man towards the moon in the 1960s
is now contained in a child's throwaway toy or given away in a Christmas
cracker. As size has decreased, the technology we use in everyday
items has increased in power exponentially.
There's no doubt that
technology brings great opportunities and innovation - but it can be
difficult to keep up with its relentless advance. The printing industry
has benefitted from invention and innovation as much as any other, but
it can be difficult to keep abreast of what all this new technology
enables us to do. For example, you may have heard of nano technology,
but are you aware of nanodot technology and what it can do? Is it just
hype for another product that we don't really need - or does it have the
potential to take production processes to a new level?
The
Nanodot revolution
Nanodot technology is a new process that has
been developed over the past few years and some believe is set to
revolutionise the print market. More specifically, it is will almost
certainly have a dramatic influence on the field of large format inkjet
sublimation. The process ensures optimal pigment dispersion due to a
combination of reducing the nanoparticles combined with fixing ionic
polymers on the actual particles. To those of us without a science
degree, in a nutshell this ensures improved ink flow, faster drying and
better stability during the print process. However, due to the huge
production investment in the latest laser spectrometers and medical
filtration systems involved in producing nanodot inks, only one European
company is currently producing them.
Originally developed in
Italy, many countries such as Australia and Germany have started to use
the nanodot technology with great success. This significant new
technology was introduced in the Italian sportswear and garment
manufacturing sector last summer, causing an unprecedented wave of
production houses to change inks. At the same time, some major German
flag makers began using this new ink technology and saw impressive
results. The flag manufacturing industry is notorious for its highly
competitive price structure, so when one company starts using a new form
of technology to improve results and cut production costs, its
competitors are keen to find out what's going on. Thus far, the UK has
been slow off the mark in making use of this new technology - but that
is set to change later in 2008.
Nano Pigmentation Technology (NPT)
- how it works
As with many great innovations, the theory behind
Nano Pigmentation Technology (NPT) is relatively simple. "With NPT
sublimation ink, the dye particles are ground to sub micron size and
ionically fixed," explains Enrico Grasselli Head of R&D at J-Teck
srl. "The combination of minute sizing and the fixing process reduces
friction as the inks pass through the printing heads, yielding a more
even dispersement within the ink fluid itself. This more even
dispersement allows a denser concentration of dye to be used and less
water is needed to reach the optimum viscosity for peizo heads."
With
versatility an important part of the printing process, various NPT inks
have been developed for use on a range of different sublimation
applications. Grasselli explains that, when transfer printing, the lower
water/dye ratio has the advantage of less paper cockling - and even
offers the possibility of using a more cost effective, lighter 100g
paper.
Companies using the inks when working with direct to
textile printing have reported that the NPT inks bleed less and show
higher colour values resulting in a higher quality print. Add to this
the advantages of a faster drying and pressing times reducing production
times further - and as we all know, time is money, whatever marketplace
your organisation operates in.
Extensively Tested
During
the development and testing phase, creators J-Teck experimented with
direct printing to coated and some uncoated textiles - resulting in a
faster and more reliable result, in many cases. "Tests revealed that,
no matter how the print was produced, if NPT inks were used with a good
ICC profile, significantly less ink was used, due to the high dye
density," comments Grasselli . "Combined with the drop in downtime
caused by fewer head clogs and with less heat build up at the head
prolonging the life of the print head itself, users have reported a
potentially huge impact on reducing production costs."
J-Teck also
claim improved ink stability during transport and storage, ensuring
superior batch quality and consistent results for the user. Increased
ease and speed of ink production at J-Tecks Como, Italy production
plant, using new high tech ink processing equipment ensures faster ink
production times. "As a company we have invested a lot of time and money
in the technology to fully develop and test our product before we
released it on to the market," comments J-Teck's President Dr. Gianni
Cavallini. "Our stringent quality control procedures and faster
production have enabled us to produce several different ink types and
colours which cover specialist sublimation techniques. Tests show that
they have an industry beating wash fastness and weatherability."
Embracing the change to stay competitive
Printing, perhaps
more than many industries, is keen to embrace a new technology if a
competitive advantage can be gained. If it enables us to do things
faster, better , more cheaply and still stay reliable it is surely an
innovation worth having. Only time will tell whether this is the start
of a genuine revolution in the type of sublimation ink
[http://www.sublimation-supplies.co.uk] that becomes the industry
standard, but if the early results across other European countries are
typical, Nantodot Pigment Technology is likely to here making an impact
for the foreseeable future.
