Igihe cyose R + G + B amabara atatu agongana ugereranije, miriyoni zirenga miriyoni zirashobora kubyara.Kuki birabura?Umukara urashobora kubyazwa umusaruro mugihe igipimo cya RGB kingana, ariko bisaba wino eshatu kugirango zitange ibara rimwe, ibyo ntibishoboka mubijyanye nubukungu.Mubyukuri, umukara ukoreshwa cyane mugushushanya, niyo mpamvu mubyukuri gucapa amabara ane.Hariho indi ngingo imwe: iyo umukara wakozwe na RGB ugereranije numukara uvanze neza na wino, uwambere afite imyumvire yubusa, mugihe iyanyuma yumva iremereye.
1. Hamwe nihame ryamabara ane, biroroshye cyane kubantu bose kubyemera.Iringana na firime enye mugihe cyo gusohoka, kandi irahwanye kandi ninzira enye za cyan, magenta, umuhondo, numukara (C, M, Y, K) mumiyoboro ya IFOTO.Guhindura umuyoboro mugihe dutunganya ishusho mubyukuri ni impinduka kuri firime.
2. Meshes, utudomo nu mfuruka, inshundura ziringaniye hamwe ninshundura.Mesh: kuri santimetero kare, umubare wududomo twashyizwe, 175 mesh kubintu bisanzwe byacapwe, na mesh 60 kugeza 100 mesh kubinyamakuru, bitewe nubwiza bwimpapuro.Icapiro ridasanzwe rifite meshes zidasanzwe, bitewe nimiterere.
1. Imiterere nukuri kwishusho
Icapiro rya kijyambere rya offset rikoresha icapiro rya offset (amabara ane yerekana hejuru), ni ukuvuga, ishusho yamabara igabanijwemo amabara ane: cyan (C), ibicuruzwa (M), umuhondo (Y), umukara (B) firime y'amabara ane, hanyuma ucapishe isahani ya PS icapwa inshuro enye na offset, hanyuma ni ibicuruzwa byacapwe.
Gucapa amashusho biratandukanye na mudasobwa isanzwe yerekana amashusho.Amashusho agomba kuba muburyo bwa CMYK aho kuba RGB cyangwa ubundi buryo.Iyo isohoka, ishusho ihindurwamo utudomo, aribwo busobanutse: dpi.Nibisobanuro byibuze byerekana amashusho yo gucapa bigomba kugera kuri 300dpi / pigiseli / santimetero, kandi amashusho meza cyane ukunze kubona kuri mudasobwa mubisanzwe wumva ari meza cyane kuri monite.Mubyukuri, Byinshi muribi ni amashusho ya 72dpi ya RGB, kandi ibyinshi ntibishobora gukoreshwa mugucapa.Amashusho yakoreshejwe ntagomba kwerekanwa nkibisanzwe.Ntutekereze ko amashusho ashobora gukoreshwa mugucapura kuko aribyiza binyuze muri acdsee cyangwa izindi software, kandi nibyiza nyuma yo gukuza.Bagomba gufungurwa muri photoshop, kandi ingano yishusho ikoreshwa kugirango hemezwe ukuri.Ukuri.Kurugero: ifoto ifite imiterere ya 600 * 600dpi / pigiseli / santimetero, noneho ubunini bwayo burashobora kwaguka kurenza inshuro ebyiri kandi bigakoreshwa nta kibazo.Niba imyanzuro ari 300 * 300dpi, noneho irashobora kugabanuka gusa cyangwa ingano yumwimerere ntishobora kwagurwa.Niba amashusho yerekana ari 72 * 72dpi / pigiseli / santimetero, noneho ubunini bwayo bugomba kugabanuka (ubunyangamugayo bwa dpi buzaba bunini), kugeza igihe imyanzuro izaba 300 * 300dpi, irashobora gukoreshwa.(Mugihe ukoresheje iyi mikorere, shyira ikintu "Redefine Pixel" muburyo bwo guhitamo amashusho muri Photoshop ntayo.)
Imiterere yishusho isanzwe ni: TIF, JPG, PCD, PSD, PCX, EPS, GIF, BMP, nibindi.
2. Ibara ryishusho
Kubireba amagambo amwe yumwuga nko gucapa cyane, gucapa cyane, gutobora, hamwe nibara ryibara mugucapa, urashobora kwifashisha bimwe mubicapiro byibanze.Hano hari imyumvire isanzwe igomba kwitabwaho.
1, gusohoka
Hano hari umurongo winyuguti z'ubururu ukanda ku isahani yo hepfo y'umuhondo, ku isahani y'umuhondo ya firime, umwanya w'inyuguti z'ubururu ugomba kuba ari ubusa.Ibinyuranye nabyo ni ukuri kuri verisiyo yubururu, bitabaye ibyo ikintu cyubururu kizacapishwa neza kumuhondo, ibara rizahinduka, kandi umwimerere wubururu uzahinduka icyatsi.
2. Kurenga
Hano hari umurongo winyuguti yumukara ukanda ku isahani runaka itukura, hanyuma umwanya winyuguti zumukara ku isahani itukura ya firime ntugomba gufungurwa.Kuberako umukara ushobora gufata ibara iryo ariryo ryose, niba umukara urimo ubusa, cyane cyane inyandiko ntoya, ikosa rito mugucapisha bizatera inkombe yera kugaragara, kandi itandukaniro ryirabura numweru ni binini, byoroshye kubona.
3. Umukara w'amabara ane
Iki kandi nikibazo gikunze kugaragara.Mbere yo gusohora, ugomba gusuzuma niba inyandiko yumukara muri dosiye yasohotse, cyane cyane icapiro rito, iri ku isahani yumukara gusa, kandi ntigomba kugaragara ku yandi masahani atatu.Nibigaragara, ubuziranenge bwibicuruzwa byacapwe bizagabanywa.Iyo ibishushanyo bya RGB bihinduwe mubishushanyo bya CMYK, inyandiko yumukara rwose izahinduka umukara wamabara ane.Keretse niba byavuzwe ukundi, bigomba gutunganywa mbere yuko firime isohoka.
4. Ishusho iri muburyo bwa RGB
Iyo usohora amashusho muburyo bwa RGB, sisitemu ya RIP muri rusange ihita ibahindura muburyo bwa CMYK kugirango isohore.Nyamara, ubuziranenge bwibara buzagabanuka cyane, kandi ibicuruzwa byacapwe bizagira ibara ryoroheje, ntabwo ryaka, kandi ingaruka ni mbi cyane.Ishusho ihinduwe neza muburyo bwa CMYK muri photoshop.Niba ari skaneri yandikishijwe intoki, igomba kunyura muburyo bwo gukosora amabara mbere yuko ishusho ikoreshwa.
