Professional Photo Ink Jet Printers

A Summary Review
Inkjet printers advance in a colossal range of individual products, from renowned minute inkjets beneficial for home expend, to monster-sized systems to print advertising billboards and truck signs. Here are a few definitions in the range in between, to encourage with matching buyer requirements to available systems.
A useful position to commence is to understand a contrast between inkjets which offer "page-width" formats and those which are defined as "wide" or "vast format".
Page width printers generally have outputs which range from about 8.0" to 35" (about 28 cm to  97 cm) . These are most commonly feeble in the printing high-volume business communications, where contents is more primary than any need for  images and colour. Often now associated with all-in-one print/copy facilities, such inkjets are commonly employed for   billing, business letters and mailing, and individualised recount documents
Wide format printers ranging in print width from 24" up to 15' (about 75 cm to 5 m) . That's 5 metres - thus becoming massive and with fabulous capabilities. Most wide format applications involve advertising or presentation graphics, but wide format printers are also primary for large-scale drawings by architects and designers and similar trades where technical detail and large-scale output are twin requirements.
The photographic industry has its hold particular needs when deciding on which inkjet application is needed. A significant share of the production process involves the creation of prepress colour proofs for printing jobs created digitally. These printers are designed to give an factual colour preview of how the image will leer when the job is finally produced on a vast volume press. An example of an inkjet printer designed for such proof work is an Iris printer. Outputs from these are known as "iris proofs" or "irises" for short.
Additionally of course, trusty colour proofing is of absolute paramount importance in the field of photo-art. Here, wide and gigantic format printers, with multiple ink systems are specified to direct colour output over which the photographic artist has total control.
The major supplier of inkjet printers is Hewlett-Packard. This company supplies over 90 percent of the market for printers for technical drawing applications. Their major products in this sector are the Designjet and the T-series. Hewlett Packard also has the HP Designjet 5500, which is a six-colour printer mature especially for printing graphics as well Designjet Z6100 which has an eight colour pigment ink system. Other suppliers of grievous -volume wide format printers are Epson, Kodak and Canon.
Kodak offer high-speed, variable-data, inkjet printers for production printing, including the Kodak Versamark  VJ1000, VT3000, and VX5000 printing systems. These are roll-fed printers and can print at up to 300 metres per miniature!
