Ukunyathelisa okungaxhunyiwe kanye nama-offset plate

Ezweni lanamuhla, imisebenzi eningi ingenziwa ngekhompyutha namadivayisi axhuma ngqo kuwo. Lokhu kusebenza ngisho nasendlini yokunyathelisa - kusukela ekufikeni kombala wokunyathelisa, ezinye izindlela seziqalile ukulahlekelwa ukuhambisana. Noma kunjalo, lokhu akusho ukuthi iphrinta yombala manje ibhekene nawo wonke amaphephandaba nomagazini - eqinisweni, konke akulula kakhulu. Amapulethi okungaxhunyiwe angatholakali yonke indawo, ngakho-ke ungabhali phansi ukunyathelisa ukuphrinta kuma-akhawunti. Kusamanje kuyathandwa kakhulu ngenxa yezizathu eziningi ezinhle. Ngakho-ke, uma unesithakazelo ekufundeni mayelana nokunyathelisa kwe-offsets, amapulethi okucasula nakho konke okuhlobene nabo, ke lesi sihloko senu.

Kuyini?

Ngaphambi kokuba uhlole ngokuningiliziwe ukuthi yiziphi ama-flatset okumele azimele, kubalulekile ukuthi ubheke lolu hlobo lokunyathelisa. Ngosizo lwaso, kuze kube manje, amaphephandaba amaningi, omagazini kanye nezinye izincwadi eziningi zembala ziyadalwa. Igama lolu hlobo lucabanga ukuthi umsebenzi usuqedile ngaphandle kokuxhumana nephaka lokunyathelisa kanye nezinto eziprintiwe. Yilapho amapulatifomu ahlaselwe khona, ngenxa yokuthi le ndlela iyenzeka kanjani.

Isebenza kanjani?

Inqubo yokunyathelisa i-offset ilula kakhulu - njengoba usuqonde kakade, ukuma nokubonakala akuthintana - kunezinhlamvu eziningi ezenziwe ngamacwecwe e-offset phakathi kwabo. Ngamunye wabo wenza umsebenzi wayo. Ngokuvamile kunamabili - omunye unesibopho sefomu, nomunye - ngesithombe. Iyinki efomini eliphrintiwe kuqala ihanjiswa kwelinye shaft, bese liya kwelinye, futhi kusukela kulo livele liwela kokugcina.

Izinzuzo nokungalungi

Inzuzo enkulu yale ndlela yizinga eliphakeme lomphumela wokugcina - akukho iphrinta yombala wanamuhla ongadlula izinga lokushicilelwa kwe-offset. Okwesibili, kukunika ukukhetha okungekho okungenamkhawulo kwezinto ongasebenza ngazo, futhi kukunikeza ithuba lokucubungula okuphambene nokuphrinta ngemuva kokuthola umphumela omuhle. Okwesithathu, lolu hlobo lusetshenziselwa ukusabalalisa okukhulu kwezinto ezibonakalayo ngesikhathi esifushane - amaprinta ombala ngeke akwazi ukusebenza ngesivinini esinjalo uma kuziwa kwamakhulu ezinkulungwane zamakhophi. Futhi-ke, kufanele kuqaphele ukuthi, ngokugijima okukhulu, inani eliphelele liyanciphisa kakhulu.

Kodwa, yiqiniso, kunamaphutha. Okubaluleke kakhulu kulezi zidingo zokuthunyelwa kweposi. Lokhu kufaka ukuhlukaniswa kombala, ukulinganisa umbala nokunye okuningi - konke okudingeki ukwenze uma usebenzisa ukunyathelisa komshini okuvamile okukunika indaba ephelele. Ngokwemvelo, zonke lezi zinyathelo zokucubungula zenza ikhwalithi yezinto ezibonakalayo zibe ngumyalo wokuphakama okukhulu, kodwa futhi kubangele ukuthi akunakwenzeka ukwenza imiyalelo esheshayo, kuyilapho ukunyathelisa umbala kukhompyutha kungathatha kuze kube ihora ngeminyana encane. Okwesibili, umbuzo wokuthola inzuzo unomthelela - ukubunzima kwenqubo yokuqeda kwenza kube lula kakhulu ukugijima okukhulu futhi ngesikhathi esifanayo kungabi nzuzo kakhulu kwabancane. Njengoba ubona, ukunyathelisa ukucasula kunezinzuzo nezinzuzo zayo, futhi ngezinye izikhathi kungabi usizo futhi kuya kuwe ekulahlekelweni, kuyilapho kwezinye izimo kuyoba ikhambi elihle.

Amapulethi okungahambisani nokukhiqiza kwawo

Isikhathi sokukhuluma ngento ngaphandle kokukhipha ukuphrinta ngeke kwenzeke - mayelana nama-offset plate. Kungenxa yabo ukuthi izindleko zenqubo ziphezulu kakhulu - zenza ukuthi zingabi nzuzo ezinkundleni ezincane, kodwa zinenzuzo kakhulu ezinkulu. Phela, ngamunye wabo wenza ngokuhlukana. Ukukhiqizwa kwamacwecwe e-offset kuyinkimbinkimbi. Ukuzikhiqiza, kusetshenziselwa izinsimbi ezihlukahlukene ezingezona zensimbi, ekugcineni zifakwa emikhiqizweni eqediwe esetshenziselwa ukunyathelisa okuqhubekayo.

Ukuyinkimbinkimbi kwalolu hlelo kubuye futhi ukuthi ipuleti idlula ngezigaba eziningi zokuthuthukiswa ngaphambi kokuya kumakhasimende. Okokuqala kuhlanzwa noma yikuphi ukungcola, khona-ke kukhishwa i-asidi ekhethekile, lapho kuqhutshwa khona umshini kagesi, olungiselela ipuleti ukuze aqhubeke nomsebenzi kumaphephandaba, awanikeze zonke izakhiwo ezidingekayo. Ngokwemvelo, lezi akuzona zonke izigaba zokukhiqiza - ukukhiqizwa kwamapulethi okuphutha kuthatha isikhathi esiningi, kodwa izinto ezitholakalayo eziphezulu zitholakalayo ezinikeza izinga eliphakeme lokunyathelisa umbala.

Bend

Ukuze usebenzise amacwecwe e-offset ekunyathelweni, kubalulekile ukugoba imiphetho yawo ukuthola i-shaft efunayo yesilinganiso esifanele. Ngenxa yalokhu, kukhona imishini ekhethekile, lapho amapuleti ahlaselwe khona. Lesi yisigaba esibaluleke kakhulu, ngoba kufanele usebenze ngento ecacile kakhulu - ayikwazi ukubangela noma yimuphi umonakalo, ukuze ingabonakali emshinini. Ngakho-ke, ukuguqa kumele kuqhutshwe njalo kumishini ephakeme kakhulu ochwepheshe beklasi lokuqala.

Yini okufanele uyenze ngokulandelayo?

Noma kunjalo, kuyafaneleka ukuqonda ukuthi ama-offset ayikho into evuselelekayo - ayifanele inkinga eyodwa, emva kwalokho kufanele ilahlwe. Lesi esinye sezizathu ezenza izindleko zalolu hlobo lokunyathelisa ziphakeme, futhi ukwenza ukugijima okuncane akusizo izindleko. Njengoba inikezwe ukuthi zenziwa ngamaseli angewona ama-ferrous, amafayili angcolile akufanele aphonswe ngaphandle, kodwa ayenziwe ukuze aphinde avuselelwe - ngakho uzohlinzeka ngemisebenzi emvelo futhi uzokwazi ukubuyisela ingxenye yemali esetshenzisiwe.
