Ekuphrinteni kwe-offset, ingubo ye-offset idlala indima ebalulekile ekuqinisekiseni ukuphrinta kwekhwalithi ephezulu. Ukuqina kwengubo ye-offset kungenye yezinto ezibalulekile ezinquma ukusebenza kwayo. Kulesi sihloko, sizobhekisisa ukubaluleka kokuqina kwengubo ye-offset nokuthi ithinta kanjani ikhwalithi yokuphrinta iyonke.
Ingubo yokuphrinta ye-offset iyingxenye ebalulekile yenqubo yokuphrinta ye-offset, phakathi kwepuleti lokuphrinta kanye ne-substrate idlala indima ephakathi. Indima yengubo ukudlulisa uyinki kusuka epuleti lokuphrinta ukuya ku-substrate ukuze kuqinisekiswe ukunemba nokuvumelana kokukhiqizwa kwesithombe. Ukujiya kwengubo yokuphrinta ye-offset kudlala indima ebalulekile ekunqumeni ikhwalithi yokuphrinta.
Ngakho-ke, buyini ubukhulu bengubo ye-offset? Ugqinsi lwengubo ye-offset ngokuvamile lulinganiswa ngamamilimitha (mm) noma ama-micrometer (µm). Ugqinsi olujwayelekile lwezingubo zokulala lusukela ku-1.95 mm ukuya ku-2.20 mm, nogqinsi oluhlukahlukene olutholakalayo ukuze kuhlangatshezwane nezidingo ezithile zokuphrinta. Ubukhulu bengubo ye-offset buthinta ngokuqondile ikhono layo lokunamathela ebusweni bepuleti ne-substrate, okubuye kuthinte ukudluliswa kwe-inki kanye nekhwalithi yokuphrinta iyonke.
Inkampani yethu iphinde ikhiqize ama-Offset Blankets, njengalenaI-LQ-AB Adhesion Blanket Yokuphrinta kwe-Offset.
I-LQ Izingubo zokulala ezizinamathelayo zifanelekile ekuphrinteni amafomu ebhizinisi. Kulula ukusika nokuhlubula. Ukulandelela onqenqemeni lwephepha kumbalwa, kulula ukukususa nokufaka esikhundleni, inking yendawo kanye nokusebenza kokuvela kabusha kwamachashazi kuhle kakhulu.
Ukujiya kwengubo ye-offset kuwukucatshangelwa okubalulekile kwamaphrinta nabathengi bokuphrinta. Ingubo yokulala ewugqinsi inikeza ukusekela okungcono nokugoba, okubalulekile ekuzuzeni ukudluliselwa kukayinki okungaguquki kanye nokugcina ukwethembeka kwesithombe. Ukwengeza, izingubo zokulala eziwugqinsi zingasiza ukunxephezela amaphutha amancane epuletini noma ku-substrate, ngaleyo ndlela kuthuthukiswe ikhwalithi yokuphrinta.
Ngokuphambene, izingubo zokulala ezacile zingase zilungele izinhlelo zokusebenza ezithile zokuphrinta ezidinga amandla okucindezela aphansi. Kubalulekile ukuqaphela, nokho, ukuthi izingubo zokulala ezizacile zisengozini yokuguga futhi zidabuke, okuthinta ukuphila kwazo isikhathi eside nokusebenza kwazo zonke.
Ukujiya kwengubo ye-offsetakuthinti nje kuphela ukudluliswa kukayinki nokukhiqizwa kabusha kwesithombe, kodwa futhi kuthinta ikhwalithi yokuphrinta. Kuphinde kuthinte yonke inqubo yokuphrinta, okuhlanganisa ukuzuza kwamachashazi, ukungaguquguquki kombala nerejista yokuphrinta nezinye izici. Ukukhetha okulungile nokugcinwa kokuqina okufanele kwengubo ye-offset kusiza ukuthola ukuphrinta okucacile, okucacile, kuyilapho kunciphisa ukuhluka kombala nokubhalisa.
Esimeni sokuncintisana sokuphrinta kwe-churn, ikhwalithi yokuphrinta iwumehluko oyinhloko wabahlinzeki bokuphrinta kusukela kwabaqhudelana nabo. Ngokuqonda ukubaluleka kokuqina kwengubo ye-offset kanye nomthelela wayo kukhwalithi yokuphrinta, abahlinzeki bokuphrinta bangenza izinqumo ezinolwazi lapho bekhetha ingubo yokulala efanele yezidingo zabo zokuphrinta.
Lapho uhlolaizingubo zokulala, kubalulekile ukucabangela izidingo ezithile zomsebenzi wokunyathelisa, kuhlanganise ne-substrate, uyinki kanye nohlobo lomshini wokunyathelisa. Izinhlelo zokusebenza zokuphrinta ezihlukene zizodinga ubukhulu obuhlukahlukene bezingubo zokulala ukuze uthole imiphumela engcono kakhulu. Isibonelo, lapho uphrinta kuma-substrates amaholoholo noma okuthungwe, kungase kudingeke ingubo ewugqinsi ukuze kuqinisekiswe ukumbozwa kwe-inki okungaguquki kanye nokucaca kwesithombe.
Ngaphezu kwalokho, ukuthuthukiswa kobuchwepheshe be-offset blanket nakho kuye kwaholela ekwakhiweni kwezingubo zokulala ezikhethekile ukubhekana nezinselele ezithile zokunyathelisa, isibonelo, izingubo ezicindezelayo ze-offset zinganikeza ukucindezelwa okukhulu, okuholela ekudlulisweni kwe-inki okuthuthukisiwe kanye nekhwalithi yokuphrinta, ikakhulukazi kuma-substrates angalingani noma ayinselele.
Ekukhetheni izingubo zokulala, ngaphezu kokuqina, kufanele futhi kubhekwe ukucindezelwa kwengubo, ukuthungwa kwendawo nokuqina, nezinye izici, ukuqonda okuphelele kwalezi zici ukusiza abahlinzeki bokuphrinta benze izinqumo ezinolwazi ngokuhambisana nezidingo zabo zokukhiqiza. kanye namazinga ekhwalithi.
Kafushane, ukujiya kwengubo ye-offset kuyisici esiyinhloko esithinta kakhulu izinga lokuphrinta kwe-offset. Abahlinzeki bokuphrinta nabathengi bokuphrinta kufanele bacabangele ngokucophelela izidingo ezithile zemisebenzi yabo yokuphrinta futhi bakhethe ubukhulu obufanele bezingubo zokulala ukuze bathole imiphumela engcono kakhulu. Ngokuqonda umthelela wokujiya kwengubo ye-offset kukhwalithi yokuphrinta, abahlinzeki bokuphrinta bangathuthukisa ukuphuma kwabo kokuphrinta futhi balethe imiphumela ephakeme kakhulu ehlangabezana namazinga aphezulu kakhulu ekhwalithi nokuvumelana.
