Combinations Tailored for Ink Jet System Solutions, Proceedings
of IS&T's NIP 16 (2000), p 229.
Abstract:
Photo-print longevity, textile durability, signage weatherability,
and fine art archiveability have been greatly improved by selecting
the substrate and the ink together, sometimes even including
the finishing step in the process. As ink jet technology spreads
from the desktop into a diversity of new markets, many improvements
are being tied to the use of one vendor's matched ink and media.
Highlighting these approaches, this paper emphasizes the combined
chemistry developed for the inks and media for specific applications,
the impact of individual ingredients on the overall system, the
criteria for selecting the pairs, and the benefits and the problems
in developing matched sets for these system solution approaches.
Consideration of whether this specialized, selective ink and
media approach, that is the norm in tradition industrial and
commercial applications, will dominate ink jet as it gradually
invades these applications will be discussed as well as whether
this more limited matched system approach will displace efforts
in items such as UV curing inks, and cross-linking emulsions,
which are aimed at the ideal ink that is media independent, permanent
and fast drying.

Inks to Meet New Application Needs, Proceedings of IS&T NIP

Abstract:
The emerging markets for color ink jet printing have many new
and specific requirements for ink jet inks. Today's inks were
initially designed for the home and desktop market, or the addressing
and labeling industrial market. Market requirements for new,
emerging applications, often include both the quality of the
desktop market and the durability of the industrial market, while
adding highly specific needs for the application.
While highlighting these needs, this paper emphasizes the wide
range of technical paths ink formulation is taking to fulfill
these needs, from controlled colorant solubility, new ink solvents,
radiation curing, and new colorants. Some of these formulation
approaches are general and are able to impact several applications
while others are specific-substrate driven.
Ink formulations are rapidly evolving to fulfill the multiple
challenges of the emerging markets such as packaging, large format,
textiles and decorative coverings. Further tailoring of chemistries
to optimize ink ingredients for these new applications is needed,
offering major opportunities for imaging chemical vendors.
