The Pigment Print process can produce super
wide, archival printing with pigmented ink through the newly modified Roland
V8. Our printer can produce prints 64 inches wide by 100 feet with remarkable
image quality. The eight color variable droplet technology creates rich, saturated
color and dense blacks on a huge range of media. We can print on virtually
any absorbant printing material. We stock an array of archival fine art papers,
canvas, silk, duratrans, vinyl, and films.
Having used Iris printers exclusively for the first nine years of our standards
are very high, this pigment-based process rivals the Iris and can print 100
feet long with no water solubility issues. It prints with suspended pigment
that is archivally rated at over 150 years. The concern over image permanence
is a thing of the past.
Relatively recent advancements in inkjet technology use a piezo crystal at
the back of the ink reservoir. This is rather like a loudspeaker cone -- it
flexes when an electric current flows through it. Whenever a dot is required,
a current is applied to the piezo element, the element flexes and in so doing
forces a drop of ink out of the nozzle.
There are several advantages to the piezo method. The process allows more
control over the shape and size of ink droplet release. The tiny fluctuations
in the crystal allow for smaller droplet sizes and hence higher nozzle density.
Unlike with thermal technology, the ink does not have to be heated and cooled
between each cycle. This saves time, and the ink itself is tailored more for
its absorption properties than its ability to withstand high temperatures.
This allows more freedom for developing new chemical properties in inks.
Current piezo inkjets have black print-heads with 128 nozzles and color (CMY)
print-heads with 192 nozzles (64 for each colour), addressing a native resolution
of 720 by 720dpi. Because the piezo process can deliver small and perfectly
formed dots with high accuracy, they are able to offer an enhanced resolution
of 1440 by 720dpi.
