Scientists at Xerox are trying to make it far easier by inventing a technology that lets you tell your printer exactly how blue or red you are feeling. Users will be able to say \u201cmake the sky a deeper blue\u201d or type the instruction \u201cmake the background carnation pink\u201d and the software will do so, Xerox promises. <\/span><\/span><\/p>\n

The patented invention is still being researched, with the aim of translating human descriptions of colour into the precise numerical codes that machines use to print colour documents. <\/span><\/span><\/p>\n

\u201cThere are many non-experts who know how they would like colour to appear but have no idea of how to manipulate the colour to get what they want,\u201d says Geoffrey Woolfe, a principal scientist with the Xerox Innovation Group. \u201cYou shouldn\u2019t have to be a colour expert to make the sky a deeper blue or add a bit of yellow to a sunset.\u201d <\/span><\/span><\/p>\n

Woolfe\u2019s work means colour adjustments could be made on office printers or commercial presses without dealing with mathematics. And once you realise how colours are achieved, you will understand how difficult it is. Cardinal red on a printer or monitor, for example, is expressed by mathematical co ordinates to identify a specific region in a three-dimensional space housing all the colours the device can display. <\/span><\/span><\/p>\n

To make the colour less orange, the colour expert distorts that region to a new region. The ability to use common words to adjust colour will benefit graphic artists, printers, photographers and others who spend time fine tuning the colours in documents. <\/span><\/span><\/p>\n

Woolfe is mapping common words used to distinguish different shades to the technical language used by printers. \u201cColour is so prevalent that one shouldn\u2019t have to be an expert to handle it.\u201d <\/span><\/span><\/p>\n

Considering that we use colour to describe our emotions as well as to describe an object, it seems odd that actually producing that colour from a printer should be so difficult.<\/p>\n","protected":false},"author":41,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_sma_x_autopost_status":"idle","_sma_x_autopost_error":"","_sma_x_post_id":"","_sma_facebook_post_id":"","_sma_instagram_post_id":"","_sma_threads_post_id":"","_sma_x_attempts":0,"footnotes":""},"categories":[15],"tags":[],"class_list":["post-47","post","type-post","status-publish","format-standard","hentry","category-hardware"],"_links":{"self":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/47"}],"collection":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/users\/41"}],"replies":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/comments?post=47"}],"version-history":[{"count":0,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/47\/revisions"}],"wp:attachment":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media?parent=47"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/categories?post=47"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/tags?post=47"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
