Wide-format printer

Wide format (aka large format) printers (contrast to vector-rendering "plotters") are generally accepted to be any computer-controlled printing machines (aka "printers") that support a maximum print roll width of between 18" and 100". Printers with capacities over 100" wide are considered Super Wide or Grand format. Wide format printers are used to print banners, posters, trade show graphics, wallpaper, murals, backlit film (aka duratrans), vehicle image wraps, electronic circuit schematics, architectural drawings, construction plans, backdrops for theatrical and media sets, and any other large format artwork or signage. Wide format printers usually employ some variant of inkjet technology to produce the printed image; and are more economical than other print methods such as screen printing for most short-run (low quantity) print projects, depending on print size, run length (quantity of prints per single original), and the type of substrate or print medium. Wide format printers are usually designed for printing onto a roll of print media that feeds incrementally during the print process, rather than onto individual sheets.

Technologies

Wide format printers can be categorized by the type of ink transfer process they employ:

• Aqueous: thermal or Piezo inkjet printers using an ink known as aqueous or water-based. The term water base is a generally accepted misnomer. The pigment is held in a non-reactive carrier solution that is sometimes water and other times a substitute liquid, including a soy based liquid used by Kodak. Aqueous ink generally comes in two flavors, Dye and UV (alternatively known as pigment). Dye ink is high color, low UV-resistant variety that offers the widest color gamut. UV ink is generally duller in color but withstands fading from UV rays. Similar in general principle to desktop inkjet printers. Finished prints using dye inks must be laminated to protect them if they are to be used outdoors while prints using UV inks can be used outdoors un-laminated for a limited time. Various substrates (media) are available, including canvases, banners, metabolized plastic and cloth. Aqueous technology requires that all materials be properly coated to accept and hold the ink.
• Solvent: this term is used to describe any ink that is not water-based. Piezo inkjet printers whose inks use petroleum or a petroleum by-product such as an acetone like carrier liquid. "Eco-Solvent" inks usually contain glycol esters or glycol ether esters and are slower drying. The resulting prints are waterproof. May be used to print directly on uncoated vinyl and other media as well as ridged substrates such as Painted/Coated Metal, Foam Board and PVC. The solvents soften the base material and allow the ink pigments to mechanically latch on to the chemically etched surface. Certain ink manufacturers have different bite based on what solvent carriers they use. Which is what makes solvent ink prints more durable than aqueous inks. However, solvent inks give off strong odor or fumes when drying, as the carrier fluid dissipates through applied heat from the printer's platen. There are various levels of solvent ink ranging from "True or Full Solvent" to "Medium/Mild Solvent" all the way down to "Eco-Solvent". The fume and odour levels decrease accordingly, so does the surface etch of the base material. Full to Medium/Mild Solvents require fume extraction to be considered safe in the working environment. Most Eco-Solvents can be used in an office environment with minimal or tolerable odor levels.
• Dye sublimation: inks are diffused into the special print media to produce continuous-tone prints of photographic quality.
• UV: Piezo inkjet printers whose inks are UV-curable (Dry when cured with UV light). The resulting prints are waterproof, embossed & vibrant. Any media material can be used in this technology, polymer made media are best. Ceramics, glass, metals, and woods are also used with printing with this technology.
• Pen/plotter: a pen or pens are used to draw on the print substrate. Mainly used for producing CAD drawings. Generally being superseded by digital technologies such as Solvent, Aqueous, and UV.

Meeting diverse design needs in full colour wide-format

Full-colour printing increases accuracy of communication

Many latest printers offers high-speed full-colour output as well as monochrome output and quickly returns from sleep mode, realising stressfree output. 10.1-inch MultiLink-Panel makes possible intuitive operations. It meets a variety of needs in a design field and has various features accelerating the communication that utilises colour scanner. Full-colour wide-format can handle various duties and makes your business simple and speedy.

Full ColourFull-colour & All-in-one productivity They offers all three functions of plotter/copier/scanner in full colour and can increase accuracy of communication. Moreover, it makes possible effective design reviews and presentations. Usability Usability They have a 10.1 wide Super VGA Smart Operation Panel to let you copy, print or scan with an interface similar to your tablet or smartphone such as tapping to start an app and flicking to scroll through pages. Productivity Few printers realises high-speed output, monochrome 3.8ppm (A1 horizontal) and full-colour 2.1ppm (A1 horizontal – plain paper, speed priority mode). Recovery time from sleep mode is only 7 seconds. Productivity of printing drawings will increase. Ecology GELJET technology enables ink adhesion without heat, the result is outstanding energy efficiency and reduced environmental impact.
