Ngophuhliso oluqhubekayo lobugcisa bokushicilela, ukusebenza kwezixhobo zeempawu ezininzi zokushicilela ezaziwayo azizange zibe ngcono kwaye zibe ngcono, kodwa kunye neqondo lokuzenzekelayo liye laphuculwa ngokuqhubekayo. Inkqubo yolawulo olukude lombala we-inki iye yaba "uqwalaselo oluqhelekileyo" loshicilelo oluninzi olukrelekrele, okwenza ulawulo lwe-inki yombala weemveliso eziprintiweyo zilungele kwaye zithembeke. Nangona kunjalo, kwinkqubo yoshicilelo yokwenene, akukho lula ukufezekisa umbala we-inki ozinzile kwibhetshi nganye yeemveliso eziprintiweyo. Iingxaki zekhwalithi ezibangelwa ukungafani okukhulu kwimibala ye-inki zihlala zidibana nemveliso, ezibangela ilahleko kwinkampani.
Ngaphambi kokushicilela, kuyimfuneko ukwenza umsebenzi olungileyo wohlengahlengiso lwangaphambili olusekwe kumava
Okokuqala, hlengahlengisa ivolumu ye-inki yeqela ngalinye lomthombo we-inki ngokwendawo yobungqina okanyeushicileloipleyiti. Lo msebenzi kulula ukuwugqiba kumatshini oxhotyiswe ngenkqubo yokulawula i-inki ekude. Kufuneka kubekho uqikelelo olungaphezulu kwama-80% koku. Musa ukulungelelanisa umthamo we-inki kuluhlu olukhulu ngelixa ushicilela ukunqanda ukungafani kombala omkhulu.
Okwesibini, ngokweemfuno kwiphepha lenkqubo yemveliso kunye neempawu zemveliso, ukulungelelanisa kwangaphambili i-feeder, ukuqokelela iphepha, ukusebenza kwe-inki, ubungakanani boxinzelelo kunye namanye amakhonkco ukuphepha ukungxama ngexesha loshicilelo olusemthethweni. Phakathi kwabo, ukuqinisekisa ukuba i-feeder inokondla iphepha ngokuthembekileyo, ngokuqhubekayo kwaye ngokuzinzileyo yeyona nto ibalulekileyo. Abaqhubi abanamava kuqala balungelelanise kwangaphambili ukuvuthela, ukufunxa, unyawo loxinzelelo, intwasahlobo yoxinzelelo, ivili lokucinezela iphepha, igeji yecala, igeyiji yangaphambili, njl. qinisekisa ukuba i-feeder ityisa iphepha ngokutyibilikayo, kwaye uphephe izithunzi ezahlukeneyo ze-inki ngenxa yokubetha kwe-feeder. Kucetyiswa ukuba abasebenzi abanamava banokulungisa kwangaphambili i-feeder.
Ukongeza, i-viscosity, i-fluidity, kunye nokoma kwe-inki kufuneka ilungelelaniswe ngokufanelekileyo kwangaphambili ngokomgangatho wephepha elisetyenzisiweyo kunye nobukhulu bomfanekiso kunye nendawo yombhalo wemveliso eprintiweyo ukuphucula ukuprintwa kwayo kunye nokuqinisekisa ukushicilelwa okuqhelekileyo. . Umbala we-inki akufanele ulingane ngenxa yokuvalwa rhoqo ukucoca ilaphu lerabha kunye neenwele zephepha kunye nesikhumba se-inki kwi-plate yokushicilela. Ukuba izisusa ezahlukeneyo zokuncamathelisa kunye nee-oyile ze-inki zongezwa embindini wokushicilela, ukutenxa kombala kuqinisekile.
Ngamafutshane, ukwenza umsebenzi omhle wokulungiswa kwangaphambili ngaphambi kokuqala umatshini kunokunciphisa kakhulu ukungaphumeleli emva kokushicilela ngokusemthethweni, kwaye umphathi uya kuba nexesha kunye namandla okugxila kumbala we-inki.
Lungiselela ngokuchanekileyo uxinzelelo lwamanzi kunye ne-inki roller
Ngexesha lenkqubo yoshicilelo, umfanekiso kunye nenxalenye yombhalo wepleyiti yokushicilela kufuneka iqhubeke kwaye isetyenziswe ngokulinganayo ngesixa esifanelekileyo se-inki ukufumana ushicilelo olunombala we-inki ongaguqukiyo. Ke ngoko, iirola ze-inki kunye neerola ze-inki, kunye neerola ze-inki kunye nepleyiti yokushicilela, kufuneka zigcine unxibelelwano olufanelekileyo kunye nobudlelwane bokuqengqeleka ukufezekisa ukuhanjiswa kakuhle kwe-inki. Ukuba lo msebenzi awenziwanga ngokucophelela nangokuchanekileyo, umbala we-inki awuyi kuhambelana. Ke ngoko, ngalo lonke ixesha kufakwa amanzi kunye ne-inki rollers, indlela yokuqengqeleka kwe-inki isetyenziselwa ukulungisa uxinzelelo phakathi kwabo nganye nganye, endaweni yendlela yemveli yokusebenzisa igeyiji yokuvavanya uxinzelelo, kuba le yokugqibela inesikali soxinzelelo. impazamo enkulu yokwenyani ngenxa yezinto ezahlukeneyo zabantu, kwaye kufuneka ivalwe kumatshini onemibala emininzi kunye nesantya esiphezulu. Ngokumalunga nobubanzi be-inki ejikelezayo, ngokuqhelekileyo kufanelekile ukuba ube ngu-4 ukuya kwi-5 mm. Okokuqala lungelelanisa uxinzelelo phakathi kwe-inki yokudlulisa i-inki kunye ne-inki yokufaka umtya, emva koko ulungelelanise uxinzelelo phakathi kwe-inki roller kunye ne-inki stringing roller kunye ne-cylinder plate yokushicilela, kwaye ekugqibeleni ulungelelanise uxinzelelo phakathi kwe-roller yokudlulisa amanzi, i-plate roller yamanzi, i-roller yentambo yamanzi, kunye ne-roller ephakathi, kunye noxinzelelo phakathi kwe-plate roller yamanzi kunye ne-cylinder plate cylinder. Ibha ye-inki phakathi kwezi ndlela zamanzi kufuneka ibe yi-6 mm.
Izixhobo kufuneka zihlaziywe emva kweenyanga ezimbini okanye ezintathu zokusetyenziswa, kuba ububanzi be-inki roller buya kuba buncinci emva kwexesha le-friction high-speed, ngakumbi ekuhanjisweni. Uxinzelelo phakathi kwe-inki rollers iba yincinci, kwaye i-inki ayiyi kukwazi ukuhanjiswa xa ii-inki rollers ziqokelela kuzo. Xa i-feeder inqumama okanye iyeka ukuqhubeka nokushicilela, i-inki inkulu ngeli xesha, ibangela ukuba umbala we-inki we-inki yokuqala okanye amakhulu amashiti ukuba abe mnyama, kwaye ibhalansi efanelekileyo yamanzi-inki kunzima ukuyifumana. Le mpazamo ayifumaneki lula, kwaye ibonakala ngakumbi xa ushicilela ushicilelo olucolekileyo. Ngamafutshane, ukusebenza kulo mba kufuneka kucokiseke kwaye indlela kufuneka ibe yesayensi, kungenjalo iya kubangela ukuba amanzi, ibha ye-inki, umlomo kunye nomsila woshicilelo ube nobunzulu obuhlukeneyo be-inki, ngokubangela iimpazamo kunye nokwandisa ubunzima be-inki. ukusebenza.
Ukufezekisa ibhalansi ye-inki yamanzi
Njengoko sonke siyazi, ibhalansi ye-inki yamanzi yinxalenye ebalulekileyo yoshicilelo lwe-offset. Ukuba amanzi makhulu kwaye i-inki inkulu, i-inki iya kufakwa emulsified emanzini-kwi-oyile, kwaye umgangatho wemveliso eprintiweyo ngokuqinisekileyo awuyi kuba yinto efanelekileyo. Ngokuziqhelanisa nexesha elide, umbhali uye waphonononga iindlela ezithile.
Okokuqala, qinisekisa ukuba ubudlelwane boxinzelelo phakathi kwamanzi kunye ne-inki rollers kulungelelaniswa ngokufanelekileyo, kwaye umxholo wesisombululo somthombo kunye ne-isopropyl alcohol ihlangabezana nemigangatho jikelele. Ngesi siseko, vula umatshini, vala amanzi kunye neerola ze-inki, kwaye emva koko umise umatshini ukujonga ipleyiti yokushicilela. Kungcono ukuba ne-3mm encinci yokungcola okuncangathi emphethweni wepleyiti yokushicilela. Ukuthatha isixa samanzi ngeli xesha njengesixa sokuqala samanzi sokushicilela, ukushicilelwa okuqhelekileyo kweemveliso zegraphic jikelele kunokuqinisekiswa, kwaye ibhalansi ye-inki yamanzi inokufezekiswa ngokusisiseko.
Okwesibini, ubungakanani bamanzi bunokulungelelaniswa ngokuguquguqukayo ngokwezinye izinto, ezinjengendawo enkulu yepleyiti yokushicilela, indawo erhabaxa yephepha, imfuno yokongeza izongezo kwi-inki, isantya sokushicilela kunye notshintsho kwi. ubushushu bomoya kunye nokufuma.
Ukongeza, umbhali uphinde wafumanisa ukuba xa umatshini uqalwa nje ukuprintwa, ubushushu bomzimba buphantsi, kwaye xa umatshini ubaleka ngesantya esiphezulu kangangeyure enye okanye ezimbini, ubushushu bomzimba, ngakumbi ubushushu berola yerabha, buya kuthi ga ngoku. ukunyuka ngaphezu kokuphindwe kabini, okanye nangaphezulu. Ngeli xesha, umthamo wamanzi kufuneka unyuswe ngokuthe ngcembe de i-inki yamanzi ifikelele kwibhalansi entsha.
Ingabonwa ukuba akulula ukufezekisa ibhalansi ye-inki yamanzi, kwaye umqhubi kufuneka alinganise kwaye asebenzise i-dialectically. Ngaphandle koko, ukuzinza kombala we-inki kunzima ukulawula, kwaye iimveliso eziprintiweyo eziphezulu azikwazi ukuprintwa.
Ukuhlolwa kovavanyo kunye nokuhlelwa kokulandelelana kombala
Kwimveliso, sihlala sidibana nesimo esinjalo: isampuli ebonelelwa ngumthengi ayifani kakhulu, okanye idrafti ye-inkjet yombala inikezelwa ngaphandle kobungqina. Ngeli xesha, kufuneka sihlalutye imeko ethile, kwaye asikwazi ukusebenzisa indlela yokunyusa ngokungqongqo okanye ukunciphisa umthamo we-inki ukugxotha umphumo wobungqina. Nangona isondele kubungqina ekuqaleni, ukuzinza kombala we-inki akunakuqinisekiswa, kwaye ngoko umgangatho wokugqibela wemveliso eprintiweyo awunakuqinisekiswa. Kule nkalo, umzi-mveliso wokushicilela kufuneka unxibelelane ngokukhutheleyo nomthengi ngesimo sengqondo esinzima nesinoxanduva, ubonise iingxaki kunye neengcebiso zokuguqulwa kwesampulu, kwaye wenze uhlengahlengiso olufanelekileyo ngaphambi kokushicilela emva kokufumana imvume.
Kwimveliso, ukulandelelana kombala wokushicilela kumatshini wemibala emininzi ngokuqhelekileyo kugqitywa yi-viscosity ye-inki. Kuba kushicilelo olunemibala emininzi, i-inki ibekwe ngaphezulu ngendlela emanzi-ngomanzi, kuphela ngokufumana olona mgangatho uphezulu wokugqwesa apho umbala we-inki ozinzileyo nongatshintshiyo unokuprintwa. Ukulungiswa kokulandelelana kombala wokushicilela kufuneka kuhambelane neempawu kunye neemfuno zomgangatho wemveliso eprintiweyo, kwaye ayikwazi ukuhlala ingatshintshi. Ngelo xesha, i-viscosity ye-inki nayo ingalungiswa. Umzekelo, isiciko esimfusa kunye nesigqubuthelo esiluhlaza esibhakabhakeni sinemibala eyahlukeneyo yokuprinta: i-cyan yokuqala kunye ne-magenta yesibini yeyokuqala kunye ne-magenta yokuqala kunye ne-cyan yesibini kokugqibela. Ngaphandle koko, imibala eprintiweyo iya kubonwa, engeyiyo igudileyo kwaye ingazinzile. Umzekelo, kushicilelo olunombala omnyama kakhulu, umnyama kufuneka ubekwe kwiqela lemibala yokugqibela kangangoko kunokwenzeka. Ngale ndlela, ukukhazimla komnyama kungcono kwaye imikrwelo kunye nokuxubana kombala ngaphakathi kumatshini kuyaphetshwa.
Hlakulela imikhwa elungileyo yokusebenza kwaye womeleze uxanduva lomsebenzi
Xa sisenza nawuphi na umsebenzi, kufuneka sibe nemvakalelo ephezulu yoxanduva kunye nemvakalelo enamandla yomgangatho. Kufuneka silungelelanise inkqubo yokusebenza kwaye sibambelele kwimikhwa elungileyo yemveli efana "nemigangatho emithathu" kunye "nenkuthalo emithathu". Thatha uthelekiso rhoqo lweesampulu njengomzekelo. Xa uthelekisa isampuli yesiginitsha kwisampulu, ngenxa yokungafani komgama, i-engile, umthombo wokukhanya, njl. njl., okubonakalayo kuya kuba nomkhethe, okukhokelela kumbala we-inki ongahambelaniyo. Ngeli xesha, isampuli yesiginitsha kufuneka ikhutshwe kwisampuli kwaye ithelekiswe ngononophelo; ipleyiti yokushicilela ixesha elide kufuneka ibhakiwe ukunciphisa ukuphambuka kombala we-inki okubangelwa kukutshintsha kwepleyiti; ilaphu lerabha kufuneka lihlanjululwe rhoqo, kunye nephepha lokuqhawula ngaphezulu kufuneka libekwe emva kokucoca ngalunye ukwenza umbala we-inki uzinzile; emva kokuba i-feeder imisiwe, amaphepha amahlanu okanye amathandathu asanda kushicilelwa amnyama kakhulu kwaye kufuneka atsalwe ngaphandle. Isantya sokushicilela akufuneki sikhawuleze kakhulu. Into ebalulekileyo kukugcina umatshini uzinzile kwaye uqhelekileyo; xa ufaka i-inki emthonjeni we-inki, ngenxa yokuba i-inki entsha inzima kwaye inomanzi obunzima, kufuneka ivuselelwe amaxesha amaninzi ukunqanda ukuchaphazela ubungakanani be-inki kwaye ibangele ukutenxa kombala we-inki.
Abaqhubi kufuneka baqhubeke befunda, bajonge kwaye bahlalutye ngononophelo, bafumane izinto ezichaphazela utshintsho lombala we-inki kuzo zonke iinkalo, kwaye bathathe amanyathelo ahambelanayo ukukhusela ngokufanelekileyo kwaye banqobe, bazame ukuphucula ukuzinza kunye nokuhambelana kombala we-inki. iimveliso eziprintiweyo, kunye nokuphucula ngokufanelekileyo umgangatho weemveliso eziprintiweyo.
