Digital BW, The Print

Hi, My name is Paul Banks.  I am the Managing Director of Image
Alchemy Ltd.  www.image-alchemy.com

We are introducing a new graduated black ink set ("BLACK ART") at the
end of the month and we are looking for experienced beta testers
please.  We will initially make inks for the following printers: 2400,
R1800/R800, 2100, 1290, R300.

We propose to sell the inks in our Digital Image Print System (DIPS),
pre-filled and also as separate inks to be used with refillable
cartridges or other ink systems.

Prototype inks are extremely stable.  This means the particle size of
the pigment in the ink will not alter over time.  In many inks the ink
suffers from from particle size re-agglomeration, this means that the
particles join together in the ink to make larger particles.  These
larger particles will eventually lead to nozzle blocking in the
printer's print heads and cause poor printer performance.  There are
many reasons for this instability; poor pigment dispersion, chemical
incompatibilities in the ink, etc. Our inks are undergoing testing for
chemical compatibility and stability in our laboratories.  We will
guarantee the stability of our inks for up to 2 years.  Our pigments
are milled super fine to guarantee optimum performance.  The average
particle size in our inks is 120 nanometer; so small that it cannot be
seen by the naked eye!

We are using the latest laser technology to guarantee the particle
size in each and every batch of ink that we produce.  


We are showing our ink system (DIPS) at PMA, booth V258.  As newcomers
to this product sector, we would very much welcome constructive
comments please.

Thank you.
