IV. Ukucatshangelwa Komklamo Owenziwe Ngokwezifiso Wezinkomishi Zekhofi
A. Umthelela Wokukhetha Okubalulekile Kwendebe Yephepha Kumklamo Owenziwe Ngokwezifiso
Ukukhethwa kwempahla yezinkomishi zephepha kudlala indima ebalulekile ekwakhiweni okwenziwe ngokwezifiso. Izinto ezivamile zenkomishi yephepha zihlanganisa izinkomishi zephepha ezinongqimba olulodwa, izinkomishi zephepha ezinezingqimba ezimbili, nezinkomishi zephepha ezinezendlalelo ezintathu.
Inkomishi yephepha lesendlalelo esisodwa
Izinkomishi zephepha ezinesendlalelo esisodwaziwuhlobo oluvame kakhulu lwenkomishi yephepha, enento encane kakhulu. Ilungele amaphethini alula alahlwayo kanye nemiklamo. Ngemiklamo eyenziwe ngokwezifiso edinga inkimbinkimbi eyengeziwe, izinkomishi zephepha ezinongqimba olulodwa zingase zingakwazi ukukhombisa imininingwane nokuthungwa kwephethini kahle.
Inkomishi yephepha elinesendlalelo esikabili
Inkomishi yephepha elinezingqimba ezimbiliyengeza isendlalelo sokuhlukanisa phakathi kwezingqimba zangaphandle nezingaphakathi. Lokhu kwenza inkomishi yephepha iqine futhi imelane namazinga okushisa aphezulu. Izinkomishi zephepha lezingqimba ezimbili zifanele amaphethini wokuphrinta anokwakheka okuphezulu kanye nemininingwane. Okufana nama-reliefs, amaphethini, njll. Ukuthungwa kwenkomishi yephepha elinezingqimba ezimbili kungathuthukisa umphumela womklamo owenziwe ngokwezifiso.
Inkomishi yephepha elinezingqimba ezintathu
Inkomishi yephepha enezingqimba ezintathuyengeza ungqimba lwephepha elinamandla aphezulu phakathi kwezingqimba zalo zangaphakathi nezingaphandle. Lokhu kwenza inkomishi yephepha iqine futhi imelane nokushisa. Izinkomishi zephepha lezendlalelo ezintathu zifanele imiklamo eyinkimbinkimbi futhi eyenziwe ngokwezifiso kakhulu. Isibonelo, amaphethini adinga imiphumela yokuthungwa enamaleveli amaningi nethambile. Impahla yenkomishi yephepha enezendlalelo ezintathu inganikeza ikhwalithi yokuphrinta ephezulu kanye nomphumela ongcono wokubonisa iphethini.
B. Izidingo zombala nosayizi zamaphethini okuklama
Izidingo zombala nosayizi wephethini yokuklama yizici ezibalulekile okufanele zicatshangelwe ekwakhiweni kwezinkomishi zekhofi ezenziwe ngokwezifiso.
1. Ukukhetha umbala. Ngokuklama ngokwezifiso, ukukhetha umbala kubaluleke kakhulu. Ngamaphethini nemiklamo, ukukhetha imibala efanelekile kungathuthukisa amandla acacile futhi akhangayo wephethini. Ngesikhathi esifanayo, umbala udinga futhi ukucabangela izici zenqubo yokunyathelisa. Futhi iqinisekisa nokunemba nokuzinza kwemibala.
2. Izidingo zobukhulu. Usayizi wephethini yokuklama udinga ukufanisa usayizi wenkomishi yekhofi. Ngokuvamile, iphethini yokuklama idinga ukufanisa indawo yokunyathelisa yenkomishi yekhofi. Futhi kuyadingeka ukuqinisekisa ukuthi iphethini ingabonisa umphumela ocacile futhi ophelele ezinkomishini zephepha ezinobukhulu obuhlukahlukene. Ngaphezu kwalokho, kuyadingeka futhi ukucabangela isilinganiso kanye nokuhlelwa kwamaphethini ngobukhulu obuhlukene bezinkomishi.
C. Izidingo zobuchwepheshe bokuphrinta ngemininingwane yephethini
Ubuchwepheshe bokuphrinta obuhlukile bunezidingo ezihlukile zemininingwane yephethini, ngakho-ke lapho wenza ngendlela oyifisayo imiklamo yenkomishi yekhofi, kuyadingeka ukucabangela ukuguquguquka kobuchwepheshe bokuphrinta kumininingwane yephethini. Ukuphrinta kwe-offset kanye ne-flexographic kuvame ukusetshenziswa amasu okuphrinta indebe yekhofi. Bangakwazi ukuhlangabezana nezidingo zemiklamo eminingi yangokwezifiso. Lezi zindlela ezimbili zokuphrinta zingafinyelela izinga eliphezulu lokuphrinta nemininingwane yephethini. Kodwa izidingo ezithile zingase zihluke. Ukuphrinta kwe-offset kulungele ukuphatha imininingwane eyinkimbinkimbi. Futhi ukuphrinta kwe-flexographic kulungele ukuphatha i-gradient ethambile kanye nemiphumela yethunzi. Ukuphrinta kwesikrini kufaneleka kakhulu ukuphatha imininingwane yamaphethini uma kuqhathaniswa nokuphrinta kwe-offset ne-flexographic. Ukuphrinta isikrini kungakhiqiza ungqimba olukhudlwana lukayinki noma umbala. Futhi ingafinyelela imiphumela emihle yokuthungwa. Ngakho-ke, ukuphrinta kwesikrini kuyisinqumo esihle semiklamo enemininingwane eyengeziwe kanye nokwenziwa.
