In an increasingly paperless world , you ’d guess printing would become obsolete . But that ’s not the case . Because readingcomputerscreens strains people ’s eyes and they ’d favour to view as a book or paper in their manus , printing technology remains indispensible . Ink on the other paw , we could do without .
permit ’s face it – ink is mussy , expensive and high - maintenance . Would n’t it be nice to reject it ? Some old and new technologies provide the opportunity to do just that . Of naturally , whether a process is sincerely " inkless " count on what your definition of " ink " is .
Generally , dependable ink consists of a dyestuff or paint , which can be organic or inorganic , in a liquid . Adyeis a colored substance that break up in a liquid solvent , while apigmentconsists of very fine , sometimes powdery , bleached particles that do n’t dissolve , but rather are suspend in a liquid . The solvents and liquidness that hold the dyestuff or pigment can be water , or even fossil oil or alcohols [ reference : Evans ] .
Many method acting , both ancient and cutting edge , allow us to forego ink . The quondam method acting of printing process , such as etching , do n’t involve anything like ink . Engravinguses a tool to imprint or carve words or icon on a backbreaking surface . However , as impressive as it looks on particular plaques , engraving obviously ca n’t be used on common paper , so it ’s an impractical , difficult and expensive outgrowth . Another inkless printing process technique , red-hot enhancer printing process , employ foil to a surface by apply heat and pressure sensation . While the text look attractive , this method is also visionary for mass yield .
But Modern technology is allow us to print conveniently and cheaply without a driblet of ink . What are these cutting - edge inkless printing methods ? Keep read to find out .
Modern Inkless Printing Methods
Technology seems to have issue forth full circle since the invention of ink some 4,000 old age ago . Although the printing pressure , an efficient elbow room to apply ink to newspaper on a pot plate , was one of the most of import technical advance in the chronicle of world , taking ink out of the equation can simplify modernprinters .
Take , for case , the thermal facsimile automobile . This useful gizmo but needs to lend oneself heat to special thermic theme to print text or image . Without the mechanisms that ink requires , the printer is simpler , more durable , loud to defend and takes up less distance than ink printer . A different case of thermic fax machine expend ribbon rather than ink and melts the medallion to composition to print school text . take How Thermal Fax Machines Work to ascertain more about this appendage .
Conventional photocopiers in reality do n’t technically use ink either . If you ’ve ever keep a photocopier or readHow Photocopiers Work , you know that they employ a dry , powdery material calledtoner . The toner is negatively charge , and the copier uses staticelectricityto print copy . The copier uses light to evaluate the mark on the original and assembles the powdery toner to flow to positively charged area to replicate the text or range of a function . It then immix the toner to another piece of paper to make a written matter .
thermic facsimile machine machines and photocopier are far from curve edge and have n’t come closely to replacing ink . Despite their availability , citizenry still prefer the needlelike look and durable quality that ink printers produce . Nevertheless , scientist are now developing several other fascinating printing processes that might give ink a run for its money .
One company , Zink ( which stand up for zero ink ) , declare in 2007 that it has hone a engineering science for printing without ink . Using embedded dyestuff quartz glass in the paper , a pressman but needs to hold the right amount of passion to wreak those crystals alive and farm a quality print – even photos . Because there ’s no need for ink , this special paper take into account printers to be exceptionally modest . For its unveiling , Zink partnered with Polaroid , the ship’s company that pioneeredinstant film , to make an ink - free instantmobile photo printer , which is n’t much bigger than a coterie of circuit card .
Xerox , the fellowship with the name that ’s synonymous with photocopiers , is also developing an inkless printing method acting . But the outgrowth it ’s exploit on is radically unlike from predecessors . Inkless prints are n’t know for their long - lasting lastingness , but Xerox is turning this drawback into an asset . In fact , they ’re intentionally working to make inkless prints easily erasable . Although this seems counterintuitive , it makes a mess of gumption for several grounds .
In offices , many people impress newspaper to use for just a day or even less . To make this pattern more economical and environmentally friendly , Xerox is developing paper that does n’t require ink and is completely recyclable . It works this means : Xerox first coating paper inheliochromicchemicals . These chemicals darken when the newspaper publisher is disclose to ultravioletlight(UV ) . They ’re standardised to the chemicals that do certain dark glasses to darken in the sunlight and gradually buoy up again in black light . The pressman , then , merely " prints " by vaporize the composition with the right wavelength of UV light and in the correct places . The print can be used and then immediately wipe off by applying another wavelength of brightness level . With prototypes of this technology , the mark automatically evanesce 16 to 24 hour after printing . But Xerox is work to extend this time flow . Ideally , the textbook will last until the substance abuser is ready to delete it manually .
