Mayelana neFlexography kunye neendlela ze-Letterpress zokuprinta
Iintlobo ezimbini zokushicilela zorhwebo ezichazwe njengoprintwa yokunceda i-letterpress kunye ne-flexography. Kuzo zombini iimeko, umfanekiso uhanjiswe kumaphepha okanye enye i-substrate iphakanyiswe ngaphezu komgca wokuprinta . INk isetyenziswe kumgangatho ophakanyisiweyo, kwaye ke iplati idibene okanye ifakwe kwi-substrate. Inkqubo yokushicilela ukukhululeka ifana nokusebenzisa i-ink pad kunye nesitampu seerubha. Ngaphambi kokuqulunqwa kweekhompyutheni zekhompyutha kunye nokushicilelwa kwe-offset, ubuninzi bokuprinta kwakunjani uhlobo lokushicilela ukukhutshwa.
Nangona umfanekiso ozoprintwa uphakanyiswa kwiplani yokushicilela, ukushicilelwa kokunceda akuyi kubumba iileta eziphakanyisiweyo ezifana nezifunyenwe kwi-embossing kunye ne-thermography.
Flexography
Ukushicilelwa kwe- Flexography kusetshenziselwa ukupakishwa kwamaphepha kunye neeplastiki kubandakanya iikhonksi, iibhokisi zeebisi, iilebula kunye nezixhobo zokutya, kodwa zingasetyenziselwa malunga nantoni nayiphi na enye into equka ikhodibhodi enobumba, i-fabric kunye nefilimu yensimbi. I-Flexography yinguqulelo yanamhlanje ye-letterpress. Isebenzisa ii-inks ezomileyo ngokukhawuleza kwaye zisetyenziselwa ukuqhuba ixesha elide.
Izicatshulwa zokuprinta ze-photopolymer ezisetyenziselwa ukushicilela i-flexography zifane nomfanekiso ophakanyisiwe ofumana inki. Zifakwe ezijikelezweni zeesilinda ze press web. I-Flexography ifanelekile ukushicilela iipateni eziqhubekayo, ezifana nephepha lodonga kunye nesipho sokuphosa.
I-Flexography yindlela yokushicilela ngokukhawuleza. Nangona kuthatha ixesha elingakumbi ukusetyenzisa umshicileli wokushicilela kwi-flexographic ngaphezu komshini wokushicilela okhutshiwe, emva kokuba umshicileli usebenza, kufuna ukungenelelo oluncinci kubaqhubi bamashishini kwaye unako ukuqhuba ngokukhawuleza ixesha elide.
Ukuprinta kweLetterpress
I-Letterpress yindlela yokudala yokushicilela. Xa ukushicilelwa kwe-offset kwakhiwe, kwathatha indawo ye-letterpress njengendlela yokuphrinta ekhethiweyo yamaphephandaba, iincwadi kunye nezinye iimveliso eziprintwayo. Ukushicilelwa kwe-Letterpress ngoku ibonwa njengesiqhelo, kwaye isasetyenziswa kwaye ixabiswa ngokushicilelwa kwimiqulu yobuciko emigqabini, iincwadi ezinqunyelweyo, amakhadi okubulisa aphezulu, amanye amakhadi ezoshishino, amaphepha encwadi kunye neememo zomtshato.
Inkqubo eyenziwa ngezandla eziye zafuna ukuhlanganiswa kwezicatshulwa ezihlukeneyo zolu hlobo kwisakhelo ngoku isebenzayo ngokwenza iplateli ye-polymer isebenzisa inkqubo yezithombe. Idijithali yombonakalo icingwa ukuba ifilimu ize ibonwe kwi-plate. Iindawo ezingenakunikwa kwiplani zihlanjululwa, zishiya indawo eziphakanyisiweyo eziza kufumana inki. Imimandla ephakanyisiwe i-inked kwaye icinezelekile kwiphepha kwiphephandaba le-letterpress, elidlulisela umfanekiso.
Ininzi yokushicilela i-letterpress isebenzisa imibala eyodwa yeeyinki enye okanye ezimbini. Iifowuni zihamba ngokukhawuleza zithelekisa i-press speed flexographic presses.
