Our pigment print process can produce super wide, archival prints with pigmented ink using the Roland Hi-FI Jet Pro II. This printer can produce prints 74 inches wide by 100 feet with remarkable image quality. The twelve 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.
