Reglen er enkel: modulerne skal v\u00e6re tydeligt m\u00f8rkere end baggrunden. Sort p\u00e5 hvid giver et kontrastforhold p\u00e5 21:1 og er det sikreste valg. For en brandet kode skal du sigte efter mindst 4:1 og bruge 7:1 eller mere til udend\u00f8rs skiltning, hvor sollys og afstand reducerer den effektive kontrast. Denne guide giver tallene, en farvetabel og en testrutine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hvilke QR-kodefarver virker, og kan QR-koder farves?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">En QR-kode kan have n\u00e6sten enhver farve, og den kan bruge forskellige farver til modulerne og baggrunden. Et telefonkamera ser ikke farvetone. Det konverterer billedet til gr\u00e5toner og afg\u00f8r, kvadrat for kvadrat, hvad der er m\u00f8rkt og hvad der er lyst. S\u00e5 sp\u00f8rgsm\u00e5let er ikke, hvilken farve du v\u00e6lger, men hvor forskellige de to gr\u00e5tonev\u00e6rdier er.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Virker:<\/strong> marinebl\u00e5, m\u00f8rkegr\u00f8n, koksgr\u00e5, m\u00f8rklilla, m\u00f8rkebrun eller sorte moduler p\u00e5 hvid, creme eller en anden meget lys baggrund.<\/li>\n<li><strong>Virker med en test:<\/strong> m\u00f8rker\u00f8d, m\u00f8rk turkis og m\u00f8rk orange p\u00e5 hvid. Tjek f\u00f8rst forholdet, og scan et printet pr\u00f8vetryk.<\/li>\n<li><strong>Virker ikke:<\/strong> gule, lysegr\u00e5, pastelfarvede eller neonmoduler og ethvert farvepar med samme lysstyrke, s\u00e5som mellemgr\u00f8n p\u00e5 mellemr\u00f8d.<\/li>\n<li><strong>Risikabelt:<\/strong> lyse moduler p\u00e5 en m\u00f8rk baggrund (invertede koder). Mange scanner-apps l\u00e6ser dem, men nogle g\u00f8r ikke, s\u00e5 undg\u00e5 dem p\u00e5 alt, der er vigtigt.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Hvorfor kontrast styrer QR-kodescanningsevnen<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Optiske sensorer l\u00e6ser QR-koder ved at m\u00e5le forskellen i reflektion mellem m\u00f8rke og lyse moduler. QR-kodestandarden, ISO\/IEC 18004, antager m\u00f8rke moduler p\u00e5 en lys baggrund. M\u00f8rke moduler absorberer lys, og den lyse baggrund reflekterer det. Hvis forskellen er for lille, kan dekoderen ikke adskille datam\u00f8nsteret fra baggrunden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ved stregkodetest (ISO\/IEC 15415) er symbolkontrast forskellen mellem den lyseste og m\u00f8rkeste reflektans i koden. En symbolkontrast p\u00e5 70 % eller mere giver den h\u00f8jeste karakter, og under 20 % er utilstr\u00e6kkelig. Bed\u00f8mmere kontrollerer ogs\u00e5 modulation, som viser, hvor j\u00e6vnt de lyse og m\u00f8rke moduler reflekterer over hele symbolet. Uj\u00e6vne farver eller svag adskillelse f\u00e5r scanneren til at overse modulkanter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Normal polaritet, med m\u00f8rke moduler p\u00e5 en lys baggrund, fungerer p\u00e5 alle enheder. Nogle indbyggede telefonkamera-apps kan ikke l\u00e6se lyse koder p\u00e5 m\u00f8rke baggrunde, og underst\u00f8ttelsen varierer efter telefonmodel og softwareversion. Brug normal polaritet, medmindre du har testet den inverterede version p\u00e5 de enheder, dit publikum bruger.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Evaluering af farvekontrastforhold og t\u00e6rskler<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Kontrastforholdet er et tal fra 1:1 (ingen forskel) til 21:1 (sort p\u00e5 hvid). Forholdet stammer fra tilg\u00e6ngelighedsreglerne i Web Content Accessibility Guidelines (WCAG), som blev skrevet for tekst, men er en praktisk m\u00e5de at tjekke QR-farver p\u00e5. En kontrastm\u00e5ler (s\u00f8g efter \"WCAG contrast checker\") accepterer to hexkoder og returnerer forholdet.

Mindst 4:1 er minimum for indend\u00f8rs print og sk\u00e6rme. 7:1 eller mere er sikrere for emballage, flyers og alt fotograferet i varieret lys. 10:1 eller mere er m\u00e5let for udend\u00f8rs skiltning.

Planl\u00e6g en st\u00f8rre sikkerhedsmargen, end du ville indend\u00f8rs.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Brug sort eller en meget m\u00f8rk farve p\u00e5 hvid.

Glansfuld vinyl og glas reflekterer solen og forstyrrer m\u00f8nstret.<\/li>\n<li>Tilpas koden til scanningsafstanden. En almindelig regel er 1 enhed af kodens bredde for hver 10 enheder af afstand, s\u00e5 en kode scannet fra 2 meter (ca. 6,5 fod) b\u00f8r v\u00e6re omkring 20 cm (8 tommer) bred.<\/li>\n<li>Bevar den fulde stillezone, og placer koden p\u00e5 et ensfarvet lyst panel i stedet for et foto.<\/li>\n<li>Undg\u00e5 at placere koden, hvor den vender mod lav sol eller sidder bag glas, og scan det printede skilt p\u00e5 det faktiske sted, f\u00f8r du bestiller en fuld produktion.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Stregkodelkontrast: QR-koder vs. line\u00e6re stregkoder<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">De samme kontrastregler g\u00e6lder for andre stregkoder med h\u00f8j kontrast, s\u00e5som Code 128 eller EAN. Detailscannere bruger ofte en r\u00f8d laser, og r\u00f8dt lys ser ikke r\u00f8de streger eller r\u00f8d bl\u00e6k som m\u00f8rkt. For line\u00e6re stregkoder skal streger printes i sort, m\u00f8rkebl\u00e5 eller m\u00f8rkegr\u00f8n p\u00e5 hvidt, og aldrig i r\u00f8d eller orange. QR-koder l\u00e6st af et telefonkamera er mindre f\u00f8lsomme over for farvetone, men det samme r\u00e5d giver det mest p\u00e5lidelige resultat for begge.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Beskyttelse af den stillezone og kodens dimensioner<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">H\u00f8j kontrast skal str\u00e6kke sig til kanten af koden. Den tomme margen omkring m\u00f8nstret er den stillezone. Den fort\u00e6ller kameraet, hvor koden starter, og hvor andet grafik slutter.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hold en stillezone p\u00e5 mindst fire modulbredder p\u00e5 alle fire sider.<\/li>\n<li>Hold denne margen fri for tekst, illustrationer og rammer.<\/li>\n<li>Match den stillezone med din lyse baggrundsfarve, s\u00e5 gr\u00e6nsen er ren.<\/li>\n<li>Print koder p\u00e5 mindst 2 x 2 cm (0,8 x 0,8 tommer) til t\u00e6t, h\u00e5ndholdt scanning.

Kameraer konverterer billedet til gr\u00e5toner, s\u00e5 to forskellige nuancer kan ende med samme lysstyrke og smelte sammen til \u00e9n gr\u00e5.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Undg\u00e5 pastelfarvede moduler som babybl\u00e5, mint eller lysegul.<\/li>\n<li>Undg\u00e5 lysr\u00f8de eller orange moduler. Laserscannere l\u00e6ser r\u00f8dt som lyst, og kontrastforholdet er ofte under 5:1.
