Chingwe chala chala chala chodziwika chala / kukana

Kuwerenga kwabwino kwa manja a chala cham'manja mosakayikira ndi imodzi mwazowonetsa chimodzi chofunikira kwambiri cha scanner yala, imadziwikanso kuti ndi kuzindikiritsa konyenga:

(1) Gwiritsani ntchito kuchuluka: monga zomwe zalembedwa pamagawo ena, ndi zina zambiri, izi ndi magawo omwe amalimbikitsidwa ndi makampani osiyanasiyana. Kaya ndi 500dpi kapena resed - 0.1%, ndi lingaliro logwiritsa ntchito wamba, ndipo palibe njira yodziwira. Muyezo woyeserera ndikuti kuchuluka kwa kukana kuyenera kukhala ≤3% ndipo kuchuluka kwa zozindikira zabodza uyenera kukhala ≤0.001%.
. Izi zikuwoneka ngati lingaliro la kulingalira kwa masamu: pamlingo womwewo, kudziwitsa zoona zenizeni kumakwera, kuzindikirika konyenga kuli kotsika, komanso mosemphanitsa. Ichi ndi ubale wotseka. Koma chifukwa chiyani zili zolondola pamlingo wina? Chifukwa ngati njira yaukadaulo ndi bwino kusintha, zisonyezo ziwirizi zimatha kuchepetsedwa, chifukwa chake, mulingo waukadaulobe. Pofuna kufulumizitsa chitsimikizo, opanga ena amachepetsa chitetezerochi chomwe chimatha kupanga chitetezero kuti apange zithunzi zonyenga ndi kuthamanga kwamphamvu komanso kuthekera kwamphamvu. Izi zikuwoneka kawiri kawirikawiri pazala zam'manja kapena ma bocks.
Malinga ndi miyezo yoyenera, kuchuluka kwa chinsinsi cha chala cha chala chakunyumba kuyenera kukhala Level 3, ndiye kuti, kuchuluka kwa Resence ndi ≤0.1% ndi kuchuluka kwa zoyatsira zabodza ndi ≤0.001%.
Kuthetsa kwa mutu wa chala cham'manja kwa chala ndi 640 × 480, komwe ndi 300,000 DPI. Kulondola kwa zomveka zam'manja ndi ma pixel 300,000, kuchuluka kwa REBS ndi <0.1%, kuchuluka kwa zozindikira zabodza ndi <0.001%, ndipo gawo lake lachitetezo ndilokwera kuposa momwe muliri 3.
