Large-format
printers are by and large accepted to be any printer with a print width
between 16″ and 100″. Printers in excess of 100″ mark may be named
Super-Wide or Grand format. Large format printers are employed to print
streamers, placards and general poster and in some cases may be more
cost-effective than short-run process such as screen printing. Large
format printers usually use a roll of print material rather than single
sheets and may include hot-air dryers to avoid prints from sticking to
themselves as they are created.Tools for making Large Format Printers:
- Aqueous: thermal or Piezo inkjet printers employ an ink identified as aqueous or water-based. The expression water base is a usually acknowledged misnomer. The pigment is assumed in a non-reactive mover solution that is from time to time water and other times an alternative liquid, including soy sourced liquid. Aqueous ink commonly comes in 2 essences, Dye and Ultra Violet. Dye ink is extreme color, low Ultra Violet resistant variety that offers the widest color gamut. Ultra Violet ink is normally duller in color but hold up fading from Ultra Violet rays. In general principle to desktop inkjet printers. Completed prints using dye inks must be plastic-coated to safeguard them if they are to be used in the open air while prints using Ultra Violet inks can be employed outdoors un-laminated for a restricted time. A variety of materials are available, including posters, streamers, metabolized plastic and cloth. Aqueous technology needs that all materials be well coated to take and retain the ink.
- Solvent: this phrase is used to express any ink that is not water-based. Piezo inkjet printers whose inks employ oil or a petroleum by-product such as acetone as its carrier liquid. Eco-solvent inks more often than not contain glycol esters or glycol ether esters and are time-consuming drying. The time-consuming prints are waterproof. May be used to print straightforward on uncoated vinyl and other medium as well as uneven substrates such as Foam Board and PVC.
- Dye sublimation: inks are diffused into the unusual print media to create continuous-tone prints of photographic feature.
- Ultra Violet: Piezo inkjet printers whose inks are Ultra Violet -curable (Dry when cured with Ultra Violet light). The ensuing prints are waterproof, pressed & dazzling. Any medium material can be used in this technology, polymer made medium are the finest. Ceramics, glass, metals, and woods are also employed with printing with this tool.
· Pen/plotter: a pen or pens are utilized to illustrate on the print substrate. Chiefly used for producing Computer-aided design drawings. Generally being outmoded by digital technologies such as Solvent, Aqueous, and Ultra Violet.
The utmost difference concerning digital printing and traditional methods is that there is no need to swap printing plates in digital printing, while in analog printing the plates are frequently change. This end result in quicker turnaround time and reduce expense when using digital printing, other than typically a loss of some excellent picture detail by most commercial digital printing procedure. The most accepted methods comprise inkjet or laser printers that leave pigment or toner onto a large variety of substrates as well as metal, photo paper, canvas, glass, limestone, paper, and other materials.
