Pravilo je jednostavno: moduli moraju biti jasno tamniji od pozadine. Crna na beloj daje odnos kontrasta 21:1 i najsigurniji je izbor. Za brendirani kod, te\u017eite ka najmanje 4:1, a koristite 7:1 ili vi\u0161e za spoljno ogla\u0161avanje, gde sun\u010deva svetlost i udaljenost smanjuju efikasan kontrast. Ovaj vodi\u010d daje brojeve, tabelu boja i rutinu testiranja.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Koje boje QR koda funkcioni\u0161u i mogu li QR kodovi biti u boji?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">QR kod mo\u017ee biti skoro bilo koje boje i mo\u017ee koristiti razli\u010dite boje za module i pozadinu. Kamera telefona ne vidi nijansu. Ona pretvara sliku u sivu skalu i odlu\u010duje, kvadrat po kvadrat, \u0161ta je tamno, a \u0161ta svetlo. Dakle, pitanje nije koju boju odaberete, ve\u0107 koliko se razlikuju dve vrednosti sive skale.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Funkcioni\u0161e:<\/strong> teget, tamnozeleni, antracit, tamnoljubi\u010dasti, tamnosme\u0111i ili crni moduli na beloj, krem ili drugoj veoma svetloj pozadini.<\/li>\n<li><strong>Funkcioni\u0161e uz testiranje:<\/strong> tamnocrvena, tamnotirkizna i tamnonarand\u017easta na beloj.

Mnoge aplikacije za skeniranje ih \u010ditaju, ali neke ne, pa ih izbegavajte na svemu \u0161to je va\u017eno.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Za\u0161to kontrast kontroli\u0161e skenabilnost QR koda<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Opti\u010dki senzori \u010ditaju QR kodove mere\u0107i razliku u refleksiji izme\u0111u tamnih i svetlih modula. Standard za QR kod, ISO\/IEC 18004, pretpostavlja tamne module na svetloj pozadini. Tamni moduli apsorbuju svetlost, a svetla pozadina je reflektuje. Ako je razlika premala, dekoder ne mo\u017ee da odvoji \u0161ablon podataka od pozadine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">U testiranju bar kodova (ISO\/IEC 15415), kontrast simbola je razlika izme\u0111u najsvetlije i najtamnije refleksije u kodu. Kontrast simbola od 70% ili vi\u0161e zaslu\u017euje najvi\u0161u ocenu, dok manje od 20% zna\u010di neuspeh. Ocenjiva\u010di tako\u0111e proveravaju modulaciju, koja pokazuje koliko ravnomerno svetli i tamni moduli reflektuju svetlost preko celog simbola. Neujedna\u010dene boje ili slaba separacija \u010dine da skener proma\u0161i ivice modula.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Normalan polaritet, sa tamnim modulima na svetloj pozadini, radi na svakom ure\u0111aju. Neke ugra\u0111ene aplikacije za kameru na telefonu ne mogu da \u010ditaju svetle kodove na tamnoj pozadini, a podr\u0161ka se razlikuje u zavisnosti od modela telefona i verzije softvera. Koristite normalan polaritet, osim ako niste testirali invertovanu verziju na ure\u0111ajima koje koristi va\u0161a publika.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Evaluacija odnosa kontrasta boja i pragova<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Odnos kontrasta je broj od 1:1 (nema razlike) do 21:1 (crno na belom). Odnos poti\u010de iz pravila pristupa\u010dnosti u Smernicama za pristupa\u010dnost veb sadr\u017eaja (WCAG), koje su napisane za tekst, ali su prakti\u010dan na\u010din za proveru boja QR kodova. Proverava\u010d kontrasta (potra\u017eite \u201eWCAG contrast checker\u201c) prihvata dva heksadecimalna koda i vra\u0107a odnos.

Najmanje 4:1 je minimum za \u0161tampu u zatvorenom prostoru i ekrane. 7:1 ili vi\u0161e je sigurnije za pakovanja, flajere i sve \u0161to se fotografi\u0161e pri razli\u010ditom osvetljenju. 10:1 ili vi\u0161e je cilj za spolja\u0161nje natpise.

Planirajte ve\u0107u marginu sigurnosti nego \u0161to biste to radili u zatvorenom prostoru.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Koristite crnu ili vrlo tamnu boju na beloj podlozi. Ciljajte na odnos od 10:1 ili ve\u0107i.<\/li>\n<li>\u0160tampajte na mat materijalu ili dodajte mat laminat. Sjajni vinil i staklo reflektuju sunce i naru\u0161avaju obrazac.<\/li>\n<li>Dimenzionirajte kod prema udaljenosti skeniranja. Uobi\u010dajeno pravilo je 1 jedinica \u0161irine koda na svakih 10 jedinica udaljenosti, tako da bi kod skeniran sa 2 metra (oko 6,5 stopa) trebalo da bude \u0161irok oko 20 cm (8 in\u010da).<\/li>\n<li>Sa\u010duvajte punu tihu zonu i postavite kod na solidnu svetlu plo\u010du umesto na fotografiju.<\/li>\n<li>Izbegavajte postavljanje koda tamo gde je izlo\u017een niskom suncu ili iza stakla, i skenirajte od\u0161tampani znak na stvarnoj lokaciji pre naru\u010divanja pune serije.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Kontrast bar koda: QR kodovi vs. linearni bar kodovi<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ista pravila kontrasta primenjuju se na druge bar kodove visokog kontrasta, kao \u0161to su Code 128 ili EAN. Maloprodajni skeneri \u010desto koriste crveni laser, a crveno svetlo ne vidi crvene trake ili crveno mastilo kao tamno. Za linearne bar kodove, \u0161tampajte trake u crnoj, tamno plavoj ili tamno zelenoj boji na beloj podlozi, i nikada u crvenoj ili narand\u017eastoj. QR kodovi koje \u010dita kamera telefona manje su osetljivi na nijansu, ali isti savet 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 ivice koda. Prazna margina oko obrasca je tiha zona. Ona govori kameri gde po\u010dinje kod i gde se zavr\u0161ava drugi umetni\u010dki sadr\u017eaj.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dr\u017eite tihu zonu \u0161iroku najmanje \u010detiri \u0161irine modula na sve \u010detiri strane.<\/li>\n<li>Ovu marginu dr\u017eite \u010distom od teksta, ilustracija i ivica.<\/li>\n<li>Uskladite tihu zonu sa svetlom bojom pozadine kako bi granica bila \u010dista.<\/li>\n<li>\u0160tampajte kodove veli\u010dine najmanje 2 x 2 cm (0,8 x 0,8 in\u010da) za blisko, ru\u010dno skeniranje. Idite na ve\u0107e dimenzije za du\u017ee linkove, jer vi\u0161e podataka zna\u010di manje module.<\/li>\n<li>Preferirajte kratku vezu. Kratak URL stvara jednostavniji obrazac sa ve\u0107im modulima koji se bolje skeniraju pri slabom svetlu.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Tekst ili grafika unutar tihe zone je \u010dest uzrok gre\u0161aka pri skeniranju na brendiranim materijalima.
