Ukugcina ixabiso lalo liphantsi kuyathandeka kumashishini, ngelixa iingenelo zalo zokusingqongileyo zixhasa imizamo yokuzinza. Liyaguquguquka kwaye linokuguqulelwa ngokwezifiso,iphepha lokuprinta eliyi-offsetilungiselela iiprojekthi ezinkulu, ihlangabezana neemfuno ezahlukeneyo zamacandelo afana nokupapasha, ukuthengisa, kunye nemfundo. Ukongeza,iphepha lokuprinta le-offset elingagqunywanga ngomthilukhetho oluhle kakhulu kwabo bafuna ukugqitywa kwendalo, ngelixaikhadibhodi emhlophe ekwiroliifomu inika isiseko esiqinileyo kwizicelo ezahlukeneyo.
Iphepha Elingacwangciswanga kunye noMgangatho Ophezulu Wokuprinta
Iphepha elingaphandle libalasele ngomgangatho walo ophezulu wokuprinta, nto leyo eyenza ukuba libe lolona khetho luphezulu kwiimfuno ezahlukeneyo zokuprinta. Isisombululo sokuprinta sephepha elingaphandle sidla ngokuqala kwi300 ukuya kwi-2400 DPI, ngelixa ukuprinta kwedijithali kudla ngokuba phakathi150 ukuya kwi-300 DPILe DPI iphezulu ekuprinteni nge-offset iphumela kwimifanekiso ebukhali necacileyo, nto leyo ibalulekileyo kwizicelo zobungcali.
Ziliqela izinto ezinegalelo kumgangatho ogqwesileyo wokuprintwa kwephepha le-offset:
| I-Factor | Ubungqina |
|---|---|
| Ukwaleka | Amaphepha agqunyiweyo anciphisa ukufunxwa kweyinki, nto leyo ebangela imifanekiso ebukhali kunye nemibala eqaqambileyo. |
