IGrayscale vs. Art Line
Imifanekiso yeGrayscale igcina ixabiso kwiimilinganiselo zokukhazimula ngokuchasene nolwazi lombala. Umfanekiso oqhelekileyo we-grayscale u-256 shades wegrey ukusuka ku-0 (omnyama) ukuya ku-255 (umhlophe).
Umnyama omnyama nomgca wobuGcisa ngokuqhelekileyo umbala o-2 (ngokuqhelekileyo umnyama nomhlophe) ubugcisa besikrinti, ipeni kunye neenki, kunye nemifanekiso yeepencil. Ukuguqula ifoto kumgca wobugcisa (njengoko kuboniswe kumzekeliso) unokwenziwa kwimiphumo ekhethekileyo kodwa ngeeplayseli ezimnyama okanye ezimhlophe kuphela, iinkcukacha zeefoto zilahlekile.
Xa uguqula umfanekiso wesibhakabhaka kwi-B & W, umfanekiso we-grayscale ngumgomo.

RGB Izithombe
Nangona kunokwenzeka ukutshekisha umbala wombala kwi-grayscale okanye uthathe i-B & W yezithombe zedijithali (kunye neekhamera ezithile) ngaloo ndlela usuhlula umgca wemibala, ininzi yeemifanekiso esisebenzisayo ngokuqala ngombala.
Iifoto zemibala kunye neefoto zekhamera zedijithali ziqhelekileyo kwifomathi yeRGB. Ukuba akunjalo, ngokuqhelekileyo isiko ukuguqula kwi-RGB kwaye usebenze nomfanekiso (ukuhlela kwiprogram yesofthiwe yeefayile) kule fomati. Imifanekiso ye-RGB igcina imilinganiselo ebomvu, eluhlaza, kunye nohlaza okwakusesikweni ukuba yenze umbala wombala. Umbala ngamnye wenziwe ngamanani ahlukeneyo obomvu, eluhlaza kunye nohlaza okwesibhakabhaka.
Ngamanye amaxesha kuyimfuneko okanye kuyinqweneleka ukuprinta okanye ukubonisa iifoto zeMnyama neNtshonalanga (i-grayscale). Ukuba umfanekiso wasezantsi umbala, iprogram yeprogram yeprogram efana ne-Adobe Photoshop okanye iCorel Photo-Paint ingasetyenziselwa ukuguqula umbala wombala kwindlela ethile emnyama nomhlophe.
Kukho iindlela ezininzi ezikhoyo zokufumana ifoto ye-B & W ukusuka kwisithombe sombala. Uvavanyo kunye neposiso ngokuqhelekileyo yindlela efanelekileyo kakhulu. Izindlela ezininzi ezisetyenziswa kakhulu zisebenzisa "ukuguqula kwi-grayscale" okanye "i-desaturation" (okanye "ukususa umbala") kwi-software yokuhlela umfanekiso.

Guqulela kwiGreyyscale
Inkrinta zeInkjet njengeRGB ukuze ngezinye izihlandlo uphumelele kwiziphumo zokuprinta ezingcono xa uguqula umfanekiso kwakhona kwi-RGB emva kokuya kwi-grayscale - iya kuba yimibala yegrey.

Ukutshatyalaliswa (Susa imibala)
Ukuba ixabiso le-RGB yomfanekiso lidatshulwa (umbala ususiwe) ixabiso linye lilinganayo okanye lifana nelinye kumbala ngamnye, okubangele umthunzi ongaqhelekanga.
I-Desaturation iqhube i-Red, Green, ne-Blue hues ukuya kwiigrey. Umfanekiso usembala ye-RGB kodwa imibala igugu.Uma iziphumo zedaturation emfanekisweni obonakala ngathi yi-grayscale, akunjalo.

I-Grayscale ne-Desaturation kunye nezinye iindlela zokuguqula
Iyakwazi ukuhluka ukusuka kwesithombeni esinye ukuya kulandelayo kwaye ukungafani kungabonakali de ibe umfanekiso uprintwe. Uvavanyo kunye nephutha lunokuba yindlela efanelekileyo yokuyiqesha.
Ezinye iindlela zokudala umfanekiso wesigcawu ukusuka kumfanekiso wombala zibandakanya:
- Guqulela kwimodi ye-LAB uze ukhiphe kuphela isiteshi seLuminance yakho yomnyama nomhlophe. Isiphumo sihle kakhulu njengemodi ye-grayscale.
- Khipha enye yee-RGB okanye i-CMYK iziteshi, usebenzisa enye okanye udibanisa ezimbini iziteshi ukuze wenze umphumo oyifunayo.
- Esikhundleni sokususa yonke imibala ngokulinganayo nge-désaturation, sebenzisa ulawulo lwe-Hue / Saturation ukuze uhlaziye ishaneli ngalinye ngabanye ngemiphumo yesiko.
- Yakha i-monotone (kunye nombala ngaphandle kobumnyama) okanye i-duotone yombala ongeyena-mhlophe, kungekhona-umnyama omnyama nomhlophe.

Print Print Grayscale Izithombe njengeMnyama kunye ne-White Halftones
Xa ushicilelwe ngenki emnyama, umfanekiso wesigcawu uguqulwa kwipateni yamachashaza amnyama afana neetoni eziqhubekayo zomfanekiso wokuqala. Iimpawu ezimnyama zegrey ziquka amachashaza amancinci amancinane okanye amancinci ahlukeneyo. Imibala emnyama yegrey iqukethe amachaphaza amaninzi okanye amnyama amaninzi kunye nendawo esondeleyo.
Ngoko ke, xa ushicilela umfanekiso we-grayscale nge inkenki emnyama uyaphrinta imifanekiso ye-B & W kuba i-halftone yimizuzu emnyama nje yeinki.
Unako ukuvelisa i-halftones yedijithali ngqo kwi-software ukuya kumshicileli. Impembelelo ye halftone esetyenzisiweyo ingacaciswa kwiiprinta zakho zePDD (i-PostScript Printer Driver) okanye isetyenziswe ngqo kwiprogram yakho yesofthiwe.
Xa ushicilela iifoto ze-B & W kumshicileli we-inkjet, iziphumo zinokuhluka ngokushicilela nge-inkino emnyama kuphela okanye ukuvumela umshicileli ukuba asebenzise imibala ye-inks ukuprinta i-shadow shades. Utshintsho lwembala - ukusuka ekungabalulekiyo ukubonakala-lungenzeka xa usebenzisa ii-inks zembala. Nangona kunjalo, inki emnyama kuphela inokulahlekelwa ezinye zeenkcukacha ezigqibeleleyo kwaye zivelise amachashaza athile ayenayo ye-ink - enye i-halftone ebonakalayo.
Ukushicilelwa kwezorhwebo, shiya imifanekiso yegrayscale kwimodi ye-grayscale ngaphandle kokuba umniki-nkonzo wakho ubonisa ngenye indlela. Ngokuxhomekeke kwindlela yokushicilela, izikrini ze-halftone ezimnyama kunye ezimhlophe zilula ngakumbi kunokuba ezinye iiprinta ze desktop zingaphumelela. Nangona kunjalo, ungacacisa izikrini zakho kwisofthiwe yakho ukuba ukhetha (okanye ukudala imiphumo ekhethekileyo).
