Uhlobo kunye nendlela yokomisa
Ngokohlobo lweoyile, inokwahlulwa ngokwezi ntlobo zilandelayo:
1) Ioli engaphezulu kwamanzi
2) Ioli ecwebezelayo ngaphezulu
3) Ioli ye-Superplastic
4) Ioli egqithisileyo
Indlela yokomisa i-oyile: ukomiswa kwe-infrared
Qaphela: Iimveliso ezine-oyile ezimacala omabini kufuneka zibekwe ngokuthe nkqo kwaye zomiswe phambi kokuba zifunyanwe. Ngenxa yokuba iimveliso ezineoli eziphindwe kabini zilula ukunamathela
imfuneko yobugcisa
Ukongeza kokungenambala kwayo, okukhazimulayo, ukoma okukhawulezayo, ukumelana neekhemikhali kunye nezinye iimpawu, ioyile ecwebezelayo kufuneka ibe nezi zinto zilandelayo:
1) Ifilimu inokucaca okuphezulu kwaye akukho mbala. Umfanekiso kunye nombhalo awuyi kutshintsha umbala emva kokumisa. Ngaphezu koko, akufuneki ukuba iguqulwe umbala okanye ibe tyheli ngenxa yokuvezwa lilanga okanye ukusetyenziswa ixesha elide.
2) Ifilimu inokumelana nokunxiba okuthile.
I-3) inokuguquguquka okuthile. Ifilimu eqaqambileyo eyenziwe naluphi na uhlobo lwe-varnish phezu kwendawo eprintiweyo kufuneka igcine i-elasticity efanelekileyo ukulungelelanisa ukuguquguquka kwephepha okanye iphepha, kwaye ayiyi konakaliswa, iqhekeze okanye ihlulwe.
4) Ifilimu inokumelana nokusingqongileyo okulungileyo. Akuvumelekanga ukutshintsha ukusebenza ngenxa yokunxibelelana ne-asidi ebuthakathaka okanye isiseko esibuthathaka kwindawo.
I-5) Inonamathela okuthile kumphezulu wezinto eziprintiweyo. Ngenxa yempembelelo yexabiso elidityanisiweyo loxinaniso lomfanekiso womphezulu kunye nombhalo we-inki yombhalo, ukunamathela komphezulu wento eprintiweyo kuncitshiswe kakhulu. Ukuze kuthintelwe ifilimu eyomileyo ukuba ingaqhekeki kwaye ihlanjululwe ekusebenziseni emva kokumisa, kufuneka ukuba ifilimu ibe ne-adhesion eqinile, kwaye inokubambelela okuthile kwi-inki kunye nezinto ezahlukeneyo ezincedisayo.
6) Umgangatho olungileyo kunye nomphezulu wefilimu ogudileyo. Umphezulu we-absorbency, ukuguda kunye nokumanzi kwezinto eziprintiweyo ziyahluka kakhulu. Ukuze wenze i-coating ecwebezelayo yenze ifilimu egudileyo kwiindawo ezahlukeneyo zemveliso, kufuneka ukuba ioli ekhazimlayo ibe nepropathi efanelekileyo yokulinganisa kunye nomphezulu wefilimu ugudile emva kokubunjwa kwefilimu.
7) Kuyafuneka ukuba ube nokulungelelaniswa okubanzi kwi-post-press processing. Okufana negilding kunye noshicilelo lwesikrini.
