Pravilo je jednostavno: moduli moraju biti jasno tamniji od pozadine. Crna na bijeloj daje omjer kontrasta 21:1 i najsigurniji je izbor. Za brendirani kod ciljajte na najmanje 4:1, a koristite 7:1 ili vi\u0161e za vanjske natpise, gdje sun\u010deva svjetlost i udaljenost smanjuju u\u010dinkovit kontrast. Ovaj vodi\u010d nudi brojke, tablicu boja i rutinu testiranja.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Koje boje QR kodova funkcioniraju i mogu li QR kodovi biti u boji?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">QR kod mo\u017ee biti gotovo bilo koje boje i mo\u017ee koristiti razli\u010dite boje za module i pozadinu. Kamera telefona ne vidi nijansu. Ona pretvara sliku u nijanse sive i odlu\u010duje, kvadrat po kvadrat, \u0161to je tamno, a \u0161to svijetlo. Stoga pitanje nije koju boju odaberete, ve\u0107 koliko su razli\u010dite dvije vrijednosti sive skale.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Radi:<\/strong> mornarski plava, tamnozelena, ugljeno siva, tamnoljubi\u010dasta, tamnosme\u0111a ili crni moduli na bijeloj, krem ili drugoj vrlo svijetloj pozadini.<\/li>\n<li><strong>Radi uz testiranje:<\/strong> tamnocrvena, tamno tirkizna i tamnonaran\u010dasta na bijeloj. Prvo provjerite omjer, a zatim skenirajte ispisani dokaz.<\/li>\n<li><strong>Ne radi:<\/strong> \u017euti, svijetlosivi, pastelni ili neonski moduli, te bilo koji par boja iste svjetline, poput srednje zelene na srednje crvenoj.<\/li>\n<li><strong>Rizi\u010dno:<\/strong> svijetli moduli na tamnoj pozadini (invertirani kodovi). Mnoge aplikacije za skeniranje ih \u010ditaju, ali neke ne, stoga ih izbjegavajte za sve \u0161to je va\u017eno.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Za\u0161to kontrast kontrolira skeniranje QR kodova<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Opti\u010dki senzori \u010ditaju QR kodove mjere\u0107i razliku u refleksiji izme\u0111u tamnih i svijetlih modula. Standard za QR kodove, ISO\/IEC 18004, pretpostavlja tamne module na svijetloj pozadini. Tamni moduli apsorbiraju svjetlost, a svijetla pozadina je reflektira. Ako je razlika premala, dekoder ne mo\u017ee odvojiti podatkovni uzorak od pozadine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">U testiranju crti\u010dnog koda (ISO\/IEC 15415), kontrast simbola je razlika izme\u0111u najsvjetlije i najtamnije refleksije u kodu. Kontrast simbola od 70% ili vi\u0161e zaslu\u017euje najvi\u0161u ocjenu, dok ispod 20% rezultira neuspjehom. Ocjenjiva\u010di tako\u0111er provjeravaju modulaciju, koja pokazuje koliko ravnomjerno svijetli i tamni moduli reflektiraju svjetlost po cijelom simbolu. Neujedna\u010dene boje ili slabo razdvajanje uzrokuju da skener propusti rubove modula.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Normalni polaritet, s tamnim modulima na svijetloj pozadini, radi na svakom ure\u0111aju. Neke ugra\u0111ene aplikacije kamere telefona ne mogu \u010ditati svijetle kodove na tamnoj pozadini, a podr\u0161ka se razlikuje ovisno o modelu telefona i verziji softvera. Koristite normalni polaritet osim ako niste testirali invertiranu verziju na ure\u0111ajima koje koristi va\u0161a publika.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Procjena omjera kontrasta boja i pragova<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Omjer kontrasta je broj od 1:1 (bez razlike) do 21:1 (crna na bijeloj). Omjer proizlazi iz pravila pristupa\u010dnosti u Smjernicama za pristupa\u010dnost web sadr\u017eaja (WCAG), koje su napisane za tekst, ali su prakti\u010dan na\u010din provjere QR boja. Provjera kontrasta (potra\u017eite \"WCAG contrast checker\") prihva\u0107a dva heksadecimalna koda i vra\u0107a omjer.

Najmanje 4:1 je minimum za unutarnji tisak i ekrane. 7:1 ili vi\u0161e sigurnije je za ambala\u017eu, letke i sve \u0161to se fotografira u razli\u010ditom osvjetljenju. 10:1 ili vi\u0161e je cilj za vanjsko ogla\u0161avanje.

Maloprodajni skeneri \u010desto koriste crveni laser, a crveno svjetlo ne vidi crvene trake ili crvenu tintu kao tamne. Za linearne bar kodove, ispisujte trake crnom, tamnoplavom ili tamnozelenom bojom na bijeloj podlozi, a nikada crvenom ili naran\u010dastom. QR kodovi koje \u010dita kamera telefona manje su osjetljivi na nijansu, ali isti savjet daje najpouzdaniji rezultat za oba.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Za\u0161tita tihe zone i dimenzija koda<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Visok kontrast mora se protezati do ruba koda. Prazan rub oko uzorka je tiha zona. Ona govori kameri gdje kod po\u010dinje i gdje zavr\u0161avaju drugi umjetni\u010dki elementi.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Zadr\u017eite tihu zonu \u0161iroku najmanje \u010detiri \u0161irine modula sa sve \u010detiri strane.<\/li>\n<li>Ovu marginu odr\u017eavajte \u010distom od teksta, ilustracija i obruba.<\/li>\n<li>Prilagodite tihu zonu boji va\u0161e svijetle pozadine kako bi granica bila \u010dista.<\/li>\n<li>Ispisujte kodove veli\u010dine najmanje 2 x 2 cm (0.8 x 0.8 in\u010da) za blisko, ru\u010dno skeniranje. Pove\u0107ajte ih za du\u017ee veze, jer vi\u0161e podataka zna\u010di manje module.<\/li>\n<li>Preferirajte kratku poveznicu. Kratki URL stvara jednostavniji uzorak s ve\u0107im modulima koji se bolje skeniraju pri slabom osvjetljenju.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Tekst ili umjetni\u010dko djelo unutar tihe zone \u010dest je uzrok pogre\u0161aka skeniranja na brendiranim materijalima.
