Ukuqonda iTekhnoloji eNgemva koomatshini boShicilelo be-Offset

Intshayelelo:

Oomatshini bokushicilela be-Offset badlala indima ebalulekileyo ekuvelisweni kwezinto ezininzi ezikumgangatho ophezulu. Ukususela kumaphephandaba kunye neemagazini ukuya kwiincwadana ezinemifanekiso kunye nokupakishwa, ukushicilela nge-offset kuye kwaba yindlela ekhethwayo yokushicilela. Kodwa basebenza njani aba matshini? Yintoni iteknoloji emva kokusebenza kwabo? Kweli nqaku, siza kungena nzulu kubugocigoci boomatshini bokushicilela beoffset, sihlola iinxalenye zabo, iindlela abazisebenzisayo kunye neenkqubo zabo. Nokuba ungumntu othanda ushicilelo okanye unomdla wokwazi ngetekhnoloji eyenza izinto eziprintiweyo ziphile, eli nqaku liza kukunika ingqiqo ebanzi yokusebenza kwangaphakathi koomatshini bokushicilela beoffset.

Iziseko zoShicilelo lwe-Offset:

Ushicilelo lwe-Offset bubuchule obuthandwayo obusetyenziselwa ukuvelisa kwakhona imifanekiso kunye nesicatshulwa kwiindawo ezahlukeneyo, ubukhulu becala iphepha. Igama elithi "offset" libhekiselele kugqithiso olungathanga ngqo lomfanekiso ukusuka kwipleyiti yokushicilela ukuya kwi-substrate. Ngokungafaniyo neendlela zokushicilela ngokuthe ngqo, ezifana ne-letterpress okanye i-flexography, i-offset printing isebenzisa i-intermediary-ingubo yerabha-ukudlulisa umfanekiso kwi-substrate. Le ndlela ibonelela ngeenzuzo ezininzi, kubandakanywa umgangatho ophezulu womfanekiso, ukuveliswa kombala ngokuchanekileyo, kunye nokukwazi ukuprinta kuluhlu olubanzi lwezinto.

Amacandelo omatshini woShicilelo we-Offset:

Oomatshini bokushicilela be-Offset ziinkqubo ezintsonkothileyo eziquka amacandelo amaninzi abalulekileyo asebenza kunye ngemvisiswano. Ukuqonda ukusebenza kwecandelo ngalinye ngundoqo ekuqondeni iteknoloji emva koomatshini bokushicilela be-offset. Makhe sihlolisise la macandelo ngokweenkcukacha:

Icwecwe lokuPrinta:

Embindini wawo wonke umatshini wokushicilela we-offset yipleyiti yokushicilela - icwecwe lentsimbi okanye ipleyiti yealuminiyam ethwele umfanekiso oza kushicilelwa. Umfanekiso okwipleyiti udalwe ngenkqubo yokucinezelwa kwangaphambili, apho ipleyiti ibonakaliswe kukukhanya kwe-UV okanye izisombululo zekhemikhali, ukuguqula iindawo ezikhethiweyo ukuze zikwazi ukwamkela inki. Emva koko ipleyiti ifakwe kwi-cylinder yepleyiti yomatshini wokushicilela, ukuvumela ukuveliswa komfanekiso ngokuchanekileyo kunye nokuhambelana.

Inkqubo yokufaka i-inking:

Inkqubo ye-inki inoxanduva lokusebenzisa i-inki kwipleyiti yokushicilela. Iqukethe uluhlu lweerola, kubandakanywa i-roller yomthombo, i-inki roller, kunye ne-distributor roller. I-roller yomthombo, efakwe kumthombo we-inki, iqokelela i-inki kwaye idlulisele kwi-roller ye-inki. I-inki roller, nayo, idlulisela i-inki kwi-distributor roller, esasaza ngokulinganayo i-inki kwi-plate yokushicilela. Inkqubo ye-inki ilinganiswe ngononophelo ukuze kuqinisekiswe ukuveliswa kombala ochanekileyo kunye nokuhanjiswa kwe-inki okuhambelanayo.

Isilinda seBlankethi:

Emva kokuba umfanekiso udluliselwe kwipleyiti yokushicilela, kufuneka idluliselwe kwi-substrate yokugqibela. Kulapho ingubo yerabha ingena khona. Isilinda sengubo sithwala ingubo yerabha, ecinezelwe kwipleyiti yokushicilela ukufumana umfanekiso weinki. Inzuzo yokusebenzisa i-rubber blanket yi-flexibility yayo, evumela ukuba ihambelane ne-contours ye-substrate. Njengoko i-cylinder yengubo ijikeleza, umfanekiso weinki uthotywa phezu kwengubo, ulungele inqanaba elilandelayo lenkqubo.

I-Impression Cylinder:

Ukudlulisa umfanekiso ukusuka kwengubo ukuya kwi-substrate, ingubo kunye ne-substrate kufuneka idibane nomnye. Oku kuphunyezwa nge-cylinder ye-impression. Isilinda esichukumisayo sicinezela i-substrate ngokuchasene nengubo, evumela ukuba umfanekiso weinki udluliselwe. Uxinzelelo olusetyenzisiweyo kufuneka lulawulwe ngokucophelela ukuze kuqinisekiswe umgangatho wokushicilela ohambelanayo kunye nokukhusela umonakalo kwi-substrate. Isilinda esibonakalayo sinokuhlengahlengiswa ukuze sikwazi ukujongana neenxalenye ezincinci ezinobunzima obahlukeneyo, zenze ushicilelo lweoffset lusebenze ngeendlela ezahlukeneyo kwizicelo ezahlukeneyo.

Indlela yePhepha:

Ecaleni kwamacandelo abalulekileyo, umatshini wokushicilela we-offset nawo ubonisa indlela yephepha eyilwe kakuhle ukukhokela i-substrate kwinkqubo yokushicilela. Umendo wephepha uqukethe ii-roller ezininzi kunye neesilinda ezivumela ukuphathwa ngokufanelekileyo kunye nokuchanekileyo kwe-substrate. Ukususela kwiyunithi yokutya ukuya kwiyunithi yokuhambisa, umendo wephepha uqinisekisa ukuhamba kakuhle kwe-substrate, ukugcina ukubhaliswa kunye nokunciphisa umngcipheko weejam zephepha. Indlela yephepha echanekileyo ibalulekile ekuphumezeni iziphumo zoshicilelo lobuchwephesha.

Inkqubo yoShicilelo ye-Offset:

Ekubeni ngoku siye sahlolisisa iinxalenye eziphambili zomatshini wokushicilela weoffset, makhe sihlolisise inkqubo yenyathelo nenyathelo elibandakanyekileyo ekuveliseni umbandela oshicilelweyo.

Cinezela kwangaphambili:

Ngaphambi kokuba kuqaliswe ukuprinta, kufuneka kulungiswe ipleyiti yokushicilela. Oku kubandakanya ukuveza ipleyiti kwisibane se-UV okanye izisombululo zekhemikhali, ezithi zitshintshe ngokukhethekayo iipropati zayo zomphezulu ukuze zamkele i-inki. Emva kokuba ipleyiti ilungile, ifakwe kwi-cylinder yeplate, ilungele ukufumana inki.

Isicelo se-Inki:

Njengoko ipleyiti yokushicilela ijikeleza kwi-cylinder yepleyiti, inkqubo ye-inking isebenzisa i-inki kumphezulu wayo. I-roller yomthombo iqokelela i-inki kumthombo we-inki, ethi ke idluliselwe kwi-inki roller kwaye isasazwe ngokulinganayo kwipleyiti yokushicilela. Imimandla engeyiyo yomfanekiso wepleyiti, egxotha amanzi, igcina i-inki, ngelixa iindawo zomfanekiso zamkela i-inki ngenxa yonyango lwazo ngexesha lokushicilela kwangaphambili.

Ukugqithiselwa kwe-Ink kwiBlankethi:

Emva kokuba i-inki isetyenziswe kwipleyiti yokushicilela, umfanekiso uhlanjululwa kwingubo yerabha njengoko i-cylinder yengubo idibana nepleyiti. Ingubo ifumana umfanekiso weinki, othe wajika ngoku kwaye ulungele ukuhanjiswa kwi-substrate.

Ukugqithiselwa koMfanekiso kwi-Substrate:

Ngomfanekiso we-inki ohlala phezu kwengubo, i-substrate iyaziswa. Isilinda esichukumisayo sicinezela i-substrate ngokuchasene nengubo, idlulisela umfanekiso weinki kumphezulu wayo. Uxinzelelo olusetyenzisiweyo luqinisekisa umgangatho ophezulu ngaphandle kokonakalisa i-substrate.

Ukomisa kunye nokuQeda:

Nje ukuba i-substrate ifumane umfanekiso we-inki, iqhubekeka ngenkqubo yokomisa ukususa nabuphi na ubumanzi obuseleyo kwaye ikhawulezise ukunyangwa kwe-inki. Iindlela ezahlukeneyo zokomisa, ezifana nezibane zobushushu okanye izomisi zomoya, zisetyenziselwa ukukhawulezisa eli nqanaba. Emva kokumisa, izinto eziprintiweyo zinokuthi zenzeke iinkqubo ezongezelelweyo zokugqiba, njengokusika, ukusonga, okanye ukubopha, ukufikelela kwifomu yokugqibela efunekayo.

Isiphelo:

Oomatshini bokushicilela be-Offset bangumxube omangalisayo wobunjineli obuchanekileyo kunye nobuchwepheshe obuphambili. Ukudityaniswa kwamacandelo ahlukeneyo, ukusuka kwipleyiti yokushicilela kunye nenkqubo ye-inki ukuya kwingubo kunye neesilinda zokubonisa, ivumela ukuveliswa kwezinto ezikumgangatho ophezulu zokushicilela kunye nokuveliswa kombala okhethekileyo kunye nesisombululo. Ukuqonda itekhnoloji emva kwaba matshini kunika ukuqonda okuxabisekileyo kubunzima benkqubo yoshicilelo kunye namanyathelo abukhali abandakanyekayo ekudaleni izixhobo zokuprinta zobungcali. Nokuba ungumshicileli onqwenelayo okanye unomdla nje welizwe loshicilelo lweoffset, ukuphonononga ubucukubhede betekhnoloji koomatshini bokushicilela beoffset kunika umbono onomdla kubugcisa kunye nesayensi yemveliso yoshicilelo.
