Iindidi ezimbini zomahluko wemibala kufuneka uyazi ukuba ukuprintwa kokupakisha

Ingxaki yokuphuhliswa kwemibala kwephakeji eprintiweyo ikhokele abasebenzi bokushicilela. Ingxaki yomahluko wombala unokulawulwa ngokufanelekileyo. Ngumgangatho womgangatho wemveliso yeNkampani, igama elidumileyo kunye nenqanaba lezakhono zenkosi. Ke ngoko, iinkampani zeengxaki kufuneka ziqwalasele.

Umbala oprintiweyo uqhutywa ngokwahlulahlulwe kabini, enye indlela: i-btch efanayo yombala wemveliso, kodwa ngombala wombala wesampulu. Ababini babhekisa kwi: I-batch efanayo yombala kukho umbala, kwaye abanye bayahambelana nesampulu, kodwa abanye abangahambelani nesampulu.

Ngoku ukusuka kwezi zinto zilandelayo esinqwenela ukuxoxa kwaye sihlalutye nawe.

Okokuqala, i-phenomeno yokuqala (ibhendi yokuqala yeemveliso zombala ofanayo, kodwa ngombala wombala wesampulu)

1, Izinto zabantu:

Inqanaba lesakhono likaPartain alinanto yakwenza, kodwa kunye nemvakalelo ye-Apteni, kuba i-batch yemveliso yemveliso ingabakho, kodwa ibonisa isampulu yesakhono, kodwa kutheni engahambelaniyo nesampulu? Ukuqala kokuqala? Oku kuxanduva lokuba luxanduva lomphathi. (Kananjalo ayiyi kubandakanyi impazamo yokutyikitya, ukuba kunjalo, le nto ihambelana nemvakalelo yoxanduva lwembobisi).

2, Umbala wePhepha:

Iphepha elimhlophe olwahlukileyo lineziphumo ezahlukeneyo kwimbonakalo yombala we-Inki. Kuba ubumhlophe bulingana nobodwa, bomvu, luhlaza okanye tyheli kwi-inki, ngenxa yoko kwi-Inki, kodwa i-inki iguqukile, kodwa eyona meko inombala wephepha lokumhlophe. Xa uvula, kufuneka usebenzise iphepha elinye. Ngenxa yobunzima, ubungakanani, ubungakanani, nangona kunjalo, kodwa ukuveliswa kwe-batch eyahlukileyo, ubumhlophe bephepha kuya kubakho umlinganiswa ongumbala wemveliso eprintiweyo. Ke kufuneka usebenzise iphepha elinye elimhlophe njengephepha eliprintiweyo.

3, IPhepha leDilesi kunye neLungelo:

I-Gloss yoPrinta ixhomekeke kwi-gloss kunye neyona phetshana lephepha. Umbala wombala we-Ofset sisigameko sokukhanya esiphezulu kwiPhepha lePhepha, ukukhanya kubonakaliswe kwi-iresina yomntu, ngokuhamba {{1} - -} umbala. Ukuba i-gloss kunye neliphenyane lephepha iphezulu, umbala esiwubonayo ngumbala oboniswe ngophawu lwe-inki, kwaye ukubekwa kombala okhanyayo kukuphakama. Ukuba iphepha elikrwada, i-gloss ephantsi, iya kuba nokucamngca, iya kunciphisa ukuxeliswa kombala ophambili, ukuze amehlo ethu anombala oshicilelayo azive elula. I-inki efanayo ilinganiswa nge-densdamometer. Iphepha elihlekisayo le-glossy, uxinzelelo oluphezulu. Iphepha le-gloss eliphantsi le-gloss enamaphepha anoxinano olusezantsi.

4, I-Shwephu iprintiweyo

Iprintwe ngefilimu, ipoliling, i-caleinder, ngaphezulu kweoyile, ukushicilela kunye nolunye unyango lomphezulu, kuya kubakho amanqanaba ahlukeneyo e-Hue utshintsho. Olunye lotshintsho lutshintsho lomzimba, ezinye iinguqu zemichiza. Utshintsho lomzimba luboniswa ikakhulu kumhlaba wemveliso olwanda ukubonakaliswa, okunefuthe elithile kulwalamano lwemibala. Umzekelo, ifilimu entsokothileyo, uVardish, ikhalenda, njl njl. Uxinizelelo lwemibala luya kunyuka. - -} Ifilimu, umbala wombala weMatte ngokuncitshiswa koxinano lwemibala. Utshintsho lwekhemikhali ikakhulu livela kwiglu, i-varnish, ioyile ye-UV njalo njalo. Ezi zixhobo ziqukethe uluhlu olubanzi lweengcinga, zonke zibangela utshintsho lombala kumbala we-inki. Ke ngoko, njengokupakisha iprinta iprinta, inkqubo yokuprinta ukuba kukho iposti -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}

Ixabiso eli-5, elomileyo

Imveliso yokuprinta i-Offset emva nje kokuprinta, i-inki isekwimeko emanzi, emva koko ixabiso lokuxinanisa kunye nexabiso elilinganayo emva kokomisa uxinano oluprintiweyo lwahlukileyo. Ukuxinana okuphezulu, ixabiso elomileyo liphantsi, le yimeko yolo eyomileyo -} ixabiso lokubuyela umva. Kungenxa yokuba i-inki iprinti iprintwe inamanqanaba athile okukhulisa. Ukwenziwa komphezulu wesipili -} ngokusekwe, kukhangeleka kumibalabala, bhetye. Xa i-inki yomile, umphezulu ubonakalisile ukucamngca, indalo iphela iphela kunakwixesha elishicilelweyo. Kwiprinta eqhelekileyo ukuze kuqinisekiswe ukuba iimveliso zeBatch kangangoko zingakwazi ukunciphisa umbala, sisebenzisa indlela yovavanyo olufanayo lokuxinana. Oko kukokuqala ukuba imveliso imanzi, isayinwe ngumthengi kwaye yavunywa kwangoko ngexabiso elilinganayo loxinano olumanzi kunye nexabiso le-L * b * b *. Emva kokuprinta imveliso (ilizwe elimanzi), ngokwexabiso lokuqala lokulinganisa ukulinganiswa kunye ne-L * A * B * B * Ixabiso lolawulo lwemibala. Ewe kunjalo, ukuba usebenzisa i-densnstoometer ngesixhobo setyhefu, inokuphelisa umphezulu we-inki ngenxa yokubonakalisa ukukhanya. Ilinganise i-sleulty engaxinanga kunye noxinano olomileyo lusondelelene, kodwa kunokunceda ukunciphisa ulawulo lombala.

6, Uxinzelelo lokuprinta:

Uxinzelelo lokuprinta yenye yeemeko ze-inki zokudluliselwa, kuba umphezulu weplate, ingubo, njl njl. If the printing pressure is less than or uneven, the ink layer is prone to the phenomenon of uneven brightness, so the process required to achieve "three flat", which requires the printing plate surface, blanket and substrate and lining the surface to achieve a relatively flat Conditions, in order to thinner layer of ink through a balanced printing pressure to print on the print to get a more uniform ink color.

Xa uxinzelelo lokuprinta alwanelanga okanye lungalingani, umzimba we-linger kunye nomphezulu weplate yokushicilela Kukho umphezulu weplate, kufuneka unyuse inani le-inki ukuze udibane neziphumo zokubonisa ubume. Nangona kunjalo, oku akuyi kunyusa kuphela ukusetyenziswa kwe-inki, kodwa kulula ukuvelisa umbala wokushicilela kunye nokushicilela i-phenomeno emdaka, ngoko ke kudle i-inki e-roller, i-roller i-roller, i-roller i-roller, i-roller isebenzisa i-pilor yombala.

7, Ukubona umthombo wokukhanya:

Imveliso yokuprinta i-Offset ekuboneni kombala kufuneka ube nomthombo wokukhanya, akukho kukhanya akunakubona umbala, kodwa ukuba umthombo wokukhanya awufani, umahluko wombala uya kuba mkhulu. Ngokubanzi, sifuna ukubonwa kombala phantsi kweemeko zokukhanya kwendalo (okt imithombo yolwazi esemgangathweni). Ukuba usebenzisa iibhulukhwe eziqhelekileyo zomthombo wokukhanya, emva koko umbala uya kubonakala tyheli, kunzima ukuchonga umbala, imveliso yokugqibela iya kuba nombala onzima. Ukongeza, amandla okukhanya kunye ne-engile yekhanyano iya kuchaphazela inkcazo yombala. Kumthombo wokukhanya okufanayo, isampulu ikhanyiwe ekubonakaliseni ubungakanani bokukhanya, ikakhulu kwisampulu kunye nomthombo wokukhanya ukumisela umgama. Kufutshane nezomeleleyo, kubeka kude kakhulu. Ke ngoko, sihlala sinikela ingqalelo kumanqaku amabini ngexesha lomsebenzi okanye ebusuku: enye kukusebenzisa umthombo wokukhanya okukhanyayo (i-400-700 okanye enye i-Angle ilinganayo. Ngeemveliso ezineemfuno zemibala ephezulu, iisampulu ze-inki ze-Inki kufuneka zibekwe ngaphezulu komgangatho wokuthelekisa, ukuze ngenxa yokujonga ukungaboni ngasonye kumbala ochanekileyo. Ke ngoko, inkqubo yokuziqhelanisa isixelela ukuba iimpawu zemithombo yokukhanya kunye nokujonga komahluko kuya kuchaphazela ngqo umbala wesazisi esichanekileyo.

Okwesibini, i-phenomeno yesibini (umbala ofanayo Kukho umbala, ezinye zinesampulu efanayo, kodwa ezinye ezingahambelani nesampulu)

1, Izinto zabantu:

Ukuba i-hue imbalwa yokuqala ye-hue, kwi-inki ayikalungelelanga tyala, yaqala ukuvula yonke indlela, i-inki yenkqubo yesakhono se-{0} {i-{0}} yezakhono ezintle, zombini zinobuchule obufanayo bokuvelisa i-batch efanayo yombala wemveliso.

2, Isisombululo seMpu:

Ukushicilelwa kwe-Offset kukusetyenziswa komgaqo weoyile - ukuziphindezela kwamanzi. La manzi abhekisa kwisisombululo somthombo. Ubungakanani bayo buchaphazela umbala we-Inki. I-inki enkulu ye-inki yombala, amanzi, i-inki encinci ye-inki iya kubunzulu imibala. Ngaphezulu amanzi amakhulu, ukuphakama okukhulu kwe-inki. I-inki ye-inki ye-inki, umbala kukukhanya. I-inki ekhuphuthiweyo ayisiyombala ombi kuphela, kodwa ikwavelisa imdaka, yeka, impatho ayinamandla, kwaye ke iingxaki ezisemgangathweni. Ke ngoko kwiprinta, ukusebenza kufuneka balawule ngokungqongqo ubungakanani besisombululo esinamanzi kwiplate yokuprinta, kwaye sisebenza kakuhle kwi-inki kunye ne-inki. Amanzi amancinci ayadingeka, ngcono.

3, Isantya sokushicilela:

Isantya sokuprinta siya kuchaphazela umbala wezinto eziprintiweyo. Kungenxa yokuba isantya semoto siya kuchaphazela i-inki ibhalansi. Vala ipleyiti yamanzi kunye nenguqulelo ecothayo yamanzi kwiplate iyahluka. I-Express yePlet yePlate yamanzi yincinci, iplate ecothayo i-vapor enkulu yamanzi. Ngenxa yotshintsho kubungakanani bamanzi kukhokelela ekungalingani kwi-inki, kuya kukhokelela kutshintsho kumbala we-inki. Ngokwesiqhelo kuprintwa mayinikele ingqalelo kwisantya esihlala sihlala, ngokuqinisekileyo asinakuqhuba ngokukhawuleza. Okwethutyana kancinci, iiprinta eziprintiweyo ziya kuvelisa umbala. Kwangelo xesha kufuneka ixhomekeke kwimeko yomatshini, lungisa ngesantya esizinzileyo. Umzekelo, abanye oomatshini bokushicilela abangenisayo abasezantsi babonisa isantya esiphezulu samashiti ali-16,000 / iyure kunye nesantya esiphezulu soomatshini basekhaya abangama-8,000 / iyure. Ezi ntengiso azizizo isantya esizinzileyo. Ngokubanzi, omabini umatshini womatshini ongeniswayo kunye nomatshini wasekhaya, isantya esizinzileyo singama-70% sesantya esiphezulu sesona si-110 / ngeyure, esi santya sinokuba lula ukulawula i-inki ibhalansi, ukunciphisa umbala.

4, roller embi:

Inkqubo yokuPrinta i-Offset, into eprintiweyo inokufumana umbala we-inki ingempela, umgangatho we-roller unendima ebaluleke kakhulu. I-cots ngokubanzi ine-inki i-Ink Rollir, i-IK Rolller kunye ne-IK Roller emithathu, banefuthe elikhulu kwimibala ye-inki. Ukuguquguquka, ukunamathela, ukujikeleza, ubunzima kunye nokugqitywa komphezulu we-inki roller ubukhulu becala kumisela umgangatho we-inki eprintiweyo. Ukuba kukho i-inki roller i-elaistity, ukungabikho kwe-viscosity, qengqeleka i-eccentric. I-Colloidal elungileyo kunye ne-Colloidal, inkqubo yokuprinta inokwenzeka ukuba ibangele i-enden okanye engazinzanga, ukuze i-inki ilungiselele i-interks engahambelaniyo. Ke ngoko, xa uprinta ukuqinisekisa ukuba umgangatho wee-cots, ukwenzela ukuba umjikelo ngamnye wokushicilela uhlanganiswe kwiplate ye-inki ifana. Ke ngoko, kumsebenzi oqhelekileyo, iroller iroller kufuneka icocwe ukuze uthuli kunye nokungcola okuphezu kwerabha kungasuswa kwaye i-inki ingadlulisele. Kwangelo xesha, uxinzelelo lonxibelelwano phakathi kweenqanawa ze-inki kunye ne-inki roller kunye neplate yokushicilela kufuneka ilungiswe. Ngaphandle koko, ukudluliselwa kwe-inki engalinganiyo kungenzeka, kukhokelela kumahluko omkhulu wombala.

5, Ulondolozo lwezixhobo:

Ukugcina intsebenzo elungileyo yoomatshini sisiqinisekiso esinokuthenjwa ukuphucula umgangatho we-inki yokuprinta. Ukuba umatshini akazinzanga, umzekelo, uxinzelelo aluhambelani, ukondla akuzinzile, ukushicilela kuhlala kubonakala kungenanto, iimeko ezininzi. Ibophelelekile ukubangela umbala wombala wokushicilela. Ke ngokufuthi kufuneka senze umsebenzi ofanelekileyo wokulungiswa kwezixhobo, ingqalelo kwiinxalenye eziphambili zezinto ezinqabileyo zoomatshini, ukuthintela ukunxiba kunye nokukrazula izixhobo ezikwimeko ezinzileyo. Njengomshicileli ophumileyo ukwenza umsebenzi olungileyo, "uMiyoshi" (uLawulo oluLungileyo, ukusebenzisa, ukulungiswa),

Zininzi izizathu zokusekwa kombala oPrinta, iindlela zokulawula nangaphezulu, ezifuna ukuba sizihlole izikhokelo zokushicilela, thabatha umkhwa wabo wokufumana amanqaku, kuthi, ingcinezelo inesithuthuko, ndiyakholelwa ukuba ixesha elide Njengobuso bokwenene, uya kuba sendleleni eya kwimpumelelo ngakumbi kwaye igudile.
