Vektorfiler skalerer til enhver st\u00f8rrelse uden at blive sl\u00f8rede eller pixelerede. Hvis du skal bruge et rasterformat som PNG, s\u00f8rg for, at opl\u00f8sningen er mindst 300 DPI ved den endelige printst\u00f8rrelse. Rasterfiler med lav opl\u00f8sning er en af de mest almindelige \u00e5rsager til ul\u00e6selige printede QR-koder.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-8c55fd95b260\"><strong class=\"schema-faq-question\">Hvordan ved jeg, om min QR-kode vil scanne efter udskrivning uden at k\u00f8re et fuldt udskriftsjob?<\/strong> <p class=\"schema-faq-answer\">Udskriv et enkelt pr\u00f8vetryk i den n\u00f8jagtige tilsigtede st\u00f8rrelse p\u00e5 det n\u00f8jagtige materiale, du planl\u00e6gger at bruge, test det derefter p\u00e5 mindst to forskellige enheder (iOS og Android) under realistiske lysforhold.
