Description
The Iris printer is an inkjet printer designed to interface with digital prepress systems to produce a hard copy that shows what the exact image will look like before the job goes to press. Such prepress output devices are used to check the image and for critical color match on industrial printing jobs such as commercial product packaging and magazine layout. Their output is also used to check color after mass production begins. Iris printers use a continuous flow ink system to produce continuous-tone dot free output. The paper used in the machine is mounted on a drum rotating at 150 inches per second. Unlike most ink jet printers which fire drops only when needed, the IRIS printer's four 1-micrometer glass jets operate continuously under high pressure, vibrated by a piezoelectric crystal to produce drops at a 1 MHz rate. The droplets are given an electric charge so that the ones that are not needed to form the image are deflected electrostatically into a waste system.
The Iris printer was originally developed by Iris Graphics, Inc. originally of Stoneham, Massachusetts, and first shipped in 1985 in the large format 3044 version. The smaller Model 3024 was introduced at the September 1987 "Lasers in Graphics" show in Miami. The company was acquired by Scitex in 1990, which was then purchased by Creo Products Inc. in 2000. In 2005 Creo was purchased by Kodak. The Iris product line evolved into the Veris printer line.
Prints produced by an Iris printer are commonly called "Iris prints", "Iris proofs" or simply "Irises".

Famous quotes containing the word description:
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
