Kappa 180 V2 - Durst Phototechnik

Kappa 180 V2 - Sustainable High-End technology from a single source
Optimum image quality combined with true added economic and ecological value are
among the top priorities of Durst customers. Therefore, every opportunity to further
increase the quality specifications has always been exhausted during development.
Print heads
For the Kappa 180 V2 Durst‘s own Quadro printer head
technology was advanced to fulfill the various textile
requirements using „QuadroZ V2“. The modified Durst
V2 printer head technology arranges the colors on the
8-channel printer heads symmetrically (mirrored).
In doing so, precise color application is ensured
for bi-directional printing directions. In addition,
any striation which can result in conventional
asymmetrically arranged printer heads at high speeds is
eliminated. Depending on the print direction, the color
channel is always located in the correct application
position, which optimizes the reproduction of crucial
designs with gradients or fine patterns. Thus color
conformity is achieved over the entire printing width
without reducing the production speed. V2 printer
head technology now enables printing on textile goods
using water-based inks over a specially hardened,
fiber-resistant nozzle plate featuring a droplet size
of 7-21 pictoliters. 6144 nozzles per color achieve a
resolution of up to 1000 dpi, and an automatic nozzle
cleaning system guarantees constant readiness for use.
The 32 QuadroZ printer heads print 8 colors in CMYK,
orange, red, blue and gray, without modulations or
density fluctuations. The ink feed system with osmosis
filtering system contributes to any existing small glass
bubbles in the inks being eliminated and guarantees
constant and failure-free printing.
Inks:
Durst has developed its own Kappa inks especially for
textile printing using inkjet technology. They enable
printing on various textile fibers using absolutely
eco-friendly, water-based dispersion, reactive, and acid
inks. Durst has obtained the coveted GOTS Certification
for the reformulated reactive ink system (Kappa Ink R)
According to Greenpeace, the Global Organic Textile
Standard (GOTS) is the most demanding seal of
approval for the entire textile production chain.
The seal is only awarded to textiles which are produced
of at least 70 percent controlled organically grown
natural fibers. All of the chemicals used, including dyes
and aids, must fulfill the specified criteria regarding
ecology and toxicology. With this reformulation, Durst
also expanded the areas of application of reactive inks
to include silk and polyamide. This means that cotton,
linen, viscose, silk and polyamide can be produced on
the same printing machine, and more vivid colors can
be achieved than when using purely acid applications.
Kappa inks are characterized by a rich black, high
brightness and excellent resistance.
