IV. Iingqwalasela kuYilo oluLungisiweyo lweKomityi yeKofu
A. Impembelelo yoKhetho lweMathiriyeli yeNdebe yePhepha kuYilo oluLungisiweyo
Ukukhethwa kwezinto eziphathekayo kwiikomityi zephepha kudlala indima ebalulekileyo kuyilo olucwangcisiweyo. Izinto eziqhelekileyo zekomityi yephepha ziquka iikomityi zephepha ezinomgca omnye, iikomityi zephepha eziphindwe kabini, kunye neekomityi zephepha ezinemigangatho emithathu.
Ikomityi yephepha enye
Iikomityi zephepha elilodwalolona hlobo luxhaphakileyo lwekomityi yephepha, enezinto ezibhityileyo. Ifanelekile kwiipateni ezilula ezilahlayo kunye noyilo. Kuyilo olulungelelanisiweyo olufuna ukuntsonkotha ngakumbi, iikomityi zephepha ezinomgca omnye zisenokungakwazi ukubonisa iinkcukacha kunye nokuthungwa kwepateni kakuhle.
Ikopi yephepha ephindwe kabini
Ikomityi yephepha ephindwe kabiniyongeza umaleko wokugquma phakathi kwamaleya angaphandle nangaphakathi. Oku kwenza ikomityi yephepha yomelele ngakumbi kwaye imelane nobushushu obuphezulu. Iikomityi zephepha eziphindwe kabini zifanelekile kwiipateni zokuprinta ezinokwakheka okuphezulu kunye neenkcukacha. Okufana ne-reliefs, iipateni, njl njl. Ukuthungwa kwekomityi yephepha eliphindwe kabini kunokunyusa umphumo woyilo olucwangcisiweyo.
Iikomityi zephepha ezintathu
Ikomityi yephepha enemigangatho emithathuyongeza umaleko wephepha elinamandla aphezulu phakathi kwamaleya angaphakathi nangaphandle. Oku kwenza ikomityi yephepha yomelele kwaye ikwazi ukumelana nobushushu. Iikomityi zephepha ezintathu zomaleko zifanelekile kuyilo oluntsonkothileyo kunye nolwenziwa ngokwesiko kakhulu. Umzekelo, iipateni ezifuna imigangatho emininzi kunye nefuthe elithambileyo lokuthungwa. Izinto eziphathekayo zekomityi yephepha elinemigangatho emithathu inokubonelela ngomgangatho ophezulu wokushicilela kunye nesiphumo esingcono sokubonisa ipateni.
B. Iimfuno zombala kunye nobukhulu kwiipateni zoyilo
Iimfuno zombala kunye nobukhulu bepateni yoyilo zizinto ezibalulekileyo ezifanele ukuqwalaselwa kuyilo lweekomityi zekofu ezenziwe ngokwezifiso.
1. Ukukhetha umbala. Kuyilo lwesiko, ukhetho lombala lubaluleke kakhulu. Iipateni kunye nokuyila, ukukhetha imibala efanelekileyo kunokwandisa amandla acacileyo kunye nokukhangayo kwepateni. Kwangaxeshanye, umbala kwakhona kufuneka uthathele ingqalelo iimpawu inkqubo yoshicilelo. Kwaye ikwaqinisekisa ukuchaneka kunye nokuzinza kwemibala.
2. Iimfuno zobukhulu. Ubungakanani bepateni yoyilo kufuneka luhambelane nobukhulu bekomityi yekhofi. Ngokuqhelekileyo, ipateni yoyilo kufuneka ihambelane nommandla wokushicilela wekomityi yekofu. Kwaye kwakhona kuyimfuneko ukuqinisekisa ukuba iphethini ingabonisa umphumo ocacileyo kunye opheleleyo kwiikomityi zephepha zobukhulu obuhlukeneyo. Ukongeza, kuyafuneka ukuba kuqwalaselwe umlinganiselo kunye nokwakheka kweepatheni kwiisayizi ezahlukeneyo zekomityi.
C. Iimfuno zeteknoloji yoshicilelo kwiinkcukacha zepateni
Iitekhnoloji ezahlukeneyo zokuprinta zineemfuno ezahlukeneyo zeenkcukacha zepateni, ngoko ke xa ulungiselela uyilo lwekomityi yekofu, kuyafuneka ukuba kuqwalaselwe ukuguquguquka kobugcisa bokushicilela kwiinkcukacha zepateni. Ukuprintwa kwe-offset kunye ne-flexographic ngokuqhelekileyo kusetyenziswa iindlela zokushicilela ikomityi yekofu. Banokuhlangabezana neemfuno zoyilo oluninzi lwesiko. Ezi ndlela zimbini zokushicilela zinokufikelela umgangatho ophezulu wokushicilela kunye neenkcukacha zepateni. Kodwa iimfuno ezithile zinokwahluka. Ushicilelo lwe-Offset lufanelekile ukuphatha iinkcukacha ezinzima. Kwaye ukuprintwa kwe-flexographic kukulungele ukuphatha i-gradient ethambileyo kunye nemiphumo yomthunzi. Ukuprintwa kwesikrini kukulungele ngakumbi ukuphatha iinkcukacha zeepateni xa kuthelekiswa ne-offset kunye ne-flexographic printing. Ukuprintwa kwesikrini kunokuvelisa umaleko otyebileyo we-inki okanye umbala. Kwaye inokufezekisa iziphumo zokuthungwa kakuhle. Ke ngoko, ukuprintwa kwesikrini lukhetho olulungileyo loyilo oluneenkcukacha ezininzi kunye nokwenziwa.
