Ukuqonda okujulile kweSigqibo sokuSebenza
Ukuba uhlalutya iirisiti, amaxwebhu, okanye ifowuni yentsapho yeso sihlandlo, i-scanner yakho yonk Nangona kunjalo, ngezinye iinjongo, ungadinga ukukhangela kwedwa. Indawo ye-ofisi idinga ukufundwa kwexwebhu . Umculi wesimboli okanye umfaki-zithombe angadinga iskena sesithombe.
Isisombululo seScan Scanner
Kwi-scanners, isisombululo se-optical sichaza ubungakanani benkcazelo enokuthi iskena sikhanywe kumgca ngamnye ojikelezayo kubalwa ngamachaphaza nge intshi (dpi). I-dpi ephezulu ifana nesisombululo esiphezulu kunye nemifanekiso esemgangathweni ephezulu ngeenkcukacha ezingaphezulu. Isisombululo esicacileyo se-optical kwi-multiple-in-one printer / scanners yi-300 dpi, engaphezulu kokuhlangabezana neemfuno zabantu abaninzi. Isisombululo sokuprinta i-office office esicinezelekileyo sisebenza ngama-600 dpi. Izigqibo zengqondo zikwazi ukufikelela phezulu kwiiskrini zezithombe zobuchwepheshe-ukuya kuma-6400 dpi akuqhelekanga.
Iskripthi esiphezulu sokusombulula ayisoloko ilingana nokutshekisha okungcono. Izicatshulwa eziphezulu ziza kunye nobukhulu befayile. Baza kuthatha indawo eninzi kwikhompyutha yakho kwaye bangathatha ixesha ukuvula, ukuhlela nokuprinta. Musa ukucinga malunga ne-imeyile.
Sisiphi isigqibo oya kuyidingayo?
Ukuphakanyiswa kwesisombululo esiyidingayo kuxhomekeke kwindlela oceba ukuyisebenzisa ngayo umfanekiso. Umbhalo wesicatshulwa ocacileyo kwi-dpi engama-300 ayiyi kuba yinto ecacileyo kumbukeli ongenasiphelo kwi-6400 dpi.
- Izikhundla zeWebhu: Uninzi lwabagadi bekhompyutheni lubonakalisa i-dpi engama-72 okanye iphakamileyo encinane kubagadi beengxelo eziphezulu, ngoko ke ukuba uhlola into eya kubonwa kwiwebhu okanye iya ku-imeyile, i-300 dpi ingaphezulu. Awuyi kulahlekelwa nantoni na ukuba uyaskena kwisisombululo esiphezulu, kodwa awuyi kuzuza nantoni na ngaphandle kobukhulu befayile, nto leyo inokuthabatha ininzi kulabo bekunye ekupheleni kwe-imeyile.
- Iifoto: Ngaphandle kokuba ucwangcisa ukwandisa iifoto, uza kufumana umgangatho ophezulu wesithombe ngokuskena kwi-300 okanye kwi-600 dpi. Ukuba uya kuphinda ubukhulu besayizi yenqobo, kabini i-dpi. Nangona kunjalo, abafaki beefoto abanobuchule bangadinga ukufumana isisombululo esiphezulu kunokwenzeka, ngokukodwa ukuba baya kukwandisa imifanekiso.
- Ukulungiswa kwesithombe: Landela ulawulo "kabini i-dpi" ukuba uceba ukunciphisa i-original ngokuyihlaba kwaye uyayandisa.
- Amaxwebhu e-Ofisi : i-300 dpi ingaphezulu kwamanqaku amaninzi. Unokuba ufuna ukuhlaziya isicatshulwa emva kwesoftware yokulungisa isithombe ukugcina indawo.
Umbala kunye neBin Deep
Umbala okanye ubunzulu bebuninzi ngumlinganiselo wolwazi umqokezeli oqokelela malunga nexwebhu okanye isithombe osihlolayo: Ukuphakama ubunzulu obuncinane, imibala emininzi isetyenziswe kwaye ikhangele bhetele ukukhangela kuyakuba. Imifanekiso ye-Grayscale yimifanekiso engama-8, kunye namanqanaba angama-256 wegrey. Imifanekiso yemifanekiso ekhishwe nge-24-bit scanner iya kuba nemibala engama-17 yezigidi; Ama-scanning 36-bit anike imibala engaphezu kweebhiliyoni ezingama-68.
I-trade-off yiyona fayile enkulu. Ngaphandle kokuba ungumfoto wezakhono okanye umyili wemifanekiso, akukho mfuneko enkulu yokuxhalabisa malunga nobunzulu bumnina, kuba amaninzi omatshini angenani ubuncinane bombala we-24-bit.
Isisombululo kunye nobunzima bunzulu bunokuchaphazela intengo yesithwebuli. Ngokubanzi, iphakamileyo isisombululo kunye nobunzulu bentsimbi, ixabiso eliphakamileyo.
Ukuhlaziya i-Scan
Ukuba unesofthiwe yokurhwefisa ifoto yezentengiso ezifana ne-Adobe Photoshop, unokwenza utshintshele iiskrini ezantsi ukuze ulondoloze indawo kwaye unganciphisi umgangatho kakhulu. Ngoko ke, ukuba i-scanner yakho ihlola nge-600 dpi kwaye uceba ukuthumela ukukhangela kwiwebhu apho i-dpi engama-72 iyisisombululo esisezantsi sesisombululo, akukho sizathu sokuba ungayifaki isisombululo. Nangona kunjalo, ukutshintsha ukutshekisha phezulu kuya kumbono omubi kumbono womgangatho.
