Izindlela ezifanelekile zokuphrinta zephakeji ngayinye ye-roaster ekhethekile zizoncika kusethi yazo ehlukile yezidingo.Amapuleti okuphrinta asetshenziswa kaningi, futhi kuze kube muva nje, amaphrinta ayengenayo enye indlela.
Uyinki udluliselwa kokuphrintiwe kumaphrinta akudala kusetshenziswa amapuleti okuphrinta.Ngenxa yokuthi amapuleti ngamanye asetshenziswa, ukwenza ngendlela oyifisayo imisebenzi yokuphrinta kungaba inselele ngoba ukusethwa kwephrinta kudinga ukushintshwa.Ukwengeza, amapuleti amaningi kufanele asetshenziselwe ukwengeza umbala emaphaketheni ekhofi, okwenza izindlela ezivamile zokunyathelisa zingahlali.
Amaphrinta amaningi asasebenzisa amaphrinta anamapuleti okuphrinta endabuko naphezu kokuthuthukiswa kobuchwepheshe bokuphrinta bedijithali.Lokhu kungenxa yokuthi zisewumshini onenani elifanele okhiqiza amaphrinti ekhwalithi enhle kakhulu.
Abaningi, nokho, baphakamisa ukukhathazeka mayelana nokusimama kwamapuleti okuphrinta njengoba umkhakha wekhofi okhethekile uqhubeka nokubeka phambili ukupakishwa okuhambisana nemvelo.
Ayini amapuleti okuphrinta?
Ipuleti lokuphrinta lenziwe ngeshidi eliqinile, ngokuvamile elenziwe nge-aluminium.
Isithombe esiphrintwayo siqoshwa eshidini eliyisicaba, elincanyana.Amapuleti aqoshwa kusetshenziswa i-acids, i-computer-to-plate (CTP) imishini, noma ubuchwepheshe be-laser.
Lokhu ngokuvamile kwenziwa iphrinta, esebenzisa imishini ekhethekile ukuze ikopishele isithombe seklayenti epuletini.
Ngokuvamile, umbala uzogqama kakhulu lapho umdwebo ujula.Kubalulekile ukukhumbula ukuthi umklamo usebenzisa ipuleti elilodwa umbala ngamunye.
Ngakho-ke, umklamo wombala uzodinga ukwakhiwa kwamapuleti amane ahlukene, ngaphandle uma umshini wokushisa ucela ngokukhethekile umklamo omnyama nomhlophe.I-Cyan, i-magenta, ephuzi, kanye “nokhiye,” okumnyama, imibala emine ye-CMYK ezomelwa enye yalezi zingcwecwe ezine.
Imibala ishintshwa ibe yifomethi ye-CMYK ngemva kokuba iphrinta ithole amafayela omklamo.Lokhu kuphinde kunqume ukuthi ungakanani umbala ngamunye kwemine okufanele isetshenziswe ukuze kutholwe umbala ofunekayo ekwakhiweni.
Oyinki babe sebefakwa epuletini ngalinye ngemva kokwenziwa, bese kamuva bedluliselwa ezintweni zokupakisha.Khona-ke, inqubo efanayo yenziwa ngombala ngamunye olandelayo.
Izibambi zamapuleti angama-cylindrical wephrinta, azungeza futhi acindezele amapuleti endaweni yokuphrinta, afakwe amapuleti.
I-Rotogravure ne-flexographic printing yizinqubo ezimbili eziyinhloko ezisebenzisa amapuleti okuphrinta.
Ekuphrinteni kwe-rotogravure, iphrinta isebenzisa umshini ojikelezayo onamasilinda aqoshwe ngomklamo.
Ukuphrinta kwe-Flexographic, ngakolunye uhlangothi, kusebenzisa amapuleti okuphrinta anezindawo eziphakeme.Naphezu kokukhetha okusheshayo nokungabizi kakhulu, ukuphrinta kwe-rotogravure kulungele kangcono ukuphrinta okude.
Kodwa-ke, ngayinye yalezi zinqubo idinga izindleko ezinkulu zangaphambili ukuze kukhiqizwe futhi kufakwe amapuleti okuphrinta.Kodwa-ke, uma zisetshenziswa njalo ngokwanele, izindleko zeyunithi ngayinye zithobekile.
Ukuhlukahluka kwe-roaster kuphinde kukhawulelwe amapuleti okuphrinta, okubavimbela ukuthi bahlukanise izikhwama zabo futhi bakhiqize amadizayini ephakheji enguqulo enomkhawulo.
Ngenxa yalokho, ukuphrinta okusekelwe epuletini kuvame ukusetshenziswa izinkampani ezinkulu zekhofi emhlabeni wonke.Intengo ngeyunithi ngayinye yale ndlela yokuphrinta inkulu kakhulu kumarosa amancane.
Yiziphi izingxenye eziya ekudaleni amapuleti okuphrinta?
Ukukhathazeka ngokuphila isikhathi eside kwamapuleti okunyathelisa kukhona ngaphezu kwentengo.
Izici ezimbili—izinto ezisetshenziselwa ukwakha ipuleti nokuthi lisetshenziswa kaningi kangakanani—zingacatshangelwa ukuze kwenziwe lokhu kuzimisela.
Amapuleti okuphrinta ngokuvamile enziwe ngensimbi, ngokuvamile insimbi ehlanganiswe ngethusi, kodwa futhi angenziwa ngepulasitiki, irabha, iphepha, noma izitsha zobumba.Ngokwemvelo, ukusimama kwento ngayinye yalezi zinto kuyahlukahluka ngokwezinga elithile.
Izinto ezihlala isikhathi esincane kakhulu zingamaphepha nezitsha zobumba, nazo ezinezingqimba zekhabhoni eziphansi kakhulu ngesikhathi sokukhiqiza.Insimbi, ipulasitiki, nenjoloba yizinto ezihlala isikhathi eside kakhulu, nokho ukwenziwa kwazo kubangela ukungcola okukhulu.
Izinto ezingcono kakhulu zokusebenzisa ikesi elithile kufanele zikhethwe abashicileli abafuna ukunciphisa umthelela wemvelo wokuphrinta kwabo.
Isibonelo, iphepha kanye ne-ceramics kungaba yizinto ezizuzisa kakhulu imvelo lapho uphrinta inani elincane.
Nokho, kungaba ukuhlakanipha ukusebenzisa izinto ezihlala isikhathi eside uma lesi silinda bekufanele sinyathelise izigidi zamakhophi.Lokhu kuvimbela isidingo sokuphindaphinda amasilinda amaningana.
Ngenxa yokuthi lawa mapuleti angase aphinde asetshenziswe, lokhu ukukhetha okuwusizo ikakhulukazi kubathosi abangashintshi umklamo wabo wokupakisha.Isilinda esisodwa se-rotogravure singasetshenziswa izikhathi ezifika ezigidini ezingu-20, okuphawulekayo.
Lawa mapuleti nawo alula ukuwahlanza, avumela ukugcinwa kuze kuphele ukuphrinta okulandelayo.Ngenxa yalokhu, ayisixazululo esihle, esingabizi sabashisi abakhulu abanokuphrinta okude.
Ukwengeza, ukusebenzisa oyinki be-organic volatile organic compound (VOC) nezinto zokupakisha ezigaywa kabusha njenge-Kraft noma iphepha lerayisi kungathuthukisa ukusimama kwalelisu.Kanye nokwenza kabusha ipuleti lokuphrinta njengoba lifinyelela ekupheleni kwempilo yalo ewusizo futhi linamathela kumklamo ofanayo wokupakisha.
Kodwa-ke, kuma-roaster amancane, ukuphrinta kwedijithali kungase kuzuzise kakhulu imvelo kunokusebenzisa amapuleti okuphrinta.
Ngokuyisisekelo, izindleko noma i-carbon footprint ezokhiqizwa amapuleti amane okuphrinta ngeke idlulwe ngenani elincane lokunyathelisa.Ukuphrinta kwedijithali kunikeza enye indlela engabizi kakhulu futhi evumelana nemvelo.
Izinzuzo zokuphrinta kwe-eco-friendly kumaphakheji wekhofi
Enye yezinkinga ezinkulu ezibhekene nebhizinisi lekhofi ukusimama.Ngaphandle kwakho, abanikazi besitolo sekhofi kanye nama-roastery abakwazi ukugcina amakhasimende abo, ukuvikela isivuno sezitshalo, noma ukunakekela imboni.
Ukupakisha kuyindawo enhle yokuqala kubathosi abafuna ukuphakamisa iziqinisekiso zemvelo zenkampani yabo.Kunezinzuzo eziningi zokusebenzisa ukuphrinta kwe-eco-friendly.
Iqinisekisa ukuthi amarosa asiza ekuvikeleni umkhakha ezinseleleni zawo ezinzima futhi kuzobaluleka kakhulu ekusizeni ngezinhlelo zokugcina amakhasimende.Ngokocwaningo lwakamuva, u-81% wabathengi ufuna ukuphatha amabhizinisi asimeme.
Ngokocwaningo oluxhunyiwe, cishe ingxenye yesine yabaphenduli bayekile ukusekela inkampani noma ukuthenga umkhiqizo othile ngenxa yezinkinga eziphathelene nezimiso zokuziphatha noma ukusimama.
Ukupakishwa kwe-Eco-friendly ngokusobala kukhanga inani elikhulayo labathengi futhi kungasiza ekuqinisekiseni ukuthi bahlala bethembekile kumkhiqizo.
Ama-roasters angakhuphula ukuqashelwa komkhiqizo phakathi kwezethameli ezibanzi futhi adale umbono omuhle womkhiqizo ngokuqinisekisa ukuthi umkhiqizo uhlotshaniswa ngokuqondile nokusimama.
Abagazingi abafuna ukusebenzisa iphakethe lekhofi elihambisana nemvelo kumele bacabangele kokubili inqubo yokuphrinta nezinto zokwakha.Usayizi wokuqalisa kokuphrinta kufanele ucatshangelwe njengento eyinhloko yokuphrinta.
Inketho evumelana kakhulu ne-eco-friendly kumarosa amancane ukusebenzisana nochwepheshe bokupakisha abasebenzisa ukuphrinta kwedijithali.
Amasu okuphrinta edijithali asebenzisa amandla amancane kakhulu futhi awadingi amapuleti okuphrinta.Ngakho-ke zibiza kancane futhi zisebenzisa izinto zokusetshenziswa eziphansi kakhulu.
Ukwengeza, banciphisa kakhulu ithonya labo endaweni ezungezile.Ngokuphawulekayo, uma kuqhathaniswa ne-rotogravure nokuphrinta kwe-flexographic, i-HP Indigo Press 25K inomphumela wemvelo ophansi ngo-80%.
Ngaphezu kwalokho, abarosa ikhofi bangaqhubeka benciphisa umthelela wekhabhoni ngokukhetha iphrinta enikeza izinto zokupakisha zekhofi ezinobungani bemvelo.
Ngokokuqala ngqa, amarosa azimele manje ayakwazi ukufinyelela emaphaketheni ekhofi angokwezifiso athengekayo futhi asimeme ngenxa yentuthuko yakamuva yobuchwepheshe bokuphrinta bedijithali.
Ukupakishwa kwekhofi kungase kuklanywe ngokuqondile futhi kuphrintwe ngedijithali e-CYANPAK ngokushintshana kwamahora angu-40 kanye nesikhathi sokuthunyelwa samahora angu-24.
Ngaphezu kwalokho, kungakhathaliseki usayizi noma impahla, sihlinzeka ngamanani aphansi we-oda (MOQs) wokupakisha.Singaqinisekisa futhi ukuthi ukupakishwa kungagaywa kabusha ngokuphelele noma kungabola ngenxa yokuthi sihlinzeka ngezikhwama ezenziwe ngezinto ezithinta imvelo ezihlanganisa i-kraft nephepha lerayisi, kanye nezikhwama ezifakwe i-LDPE ne-PLA.
