Nhanganyaya: Kupenya kwechinhu chakadhindwa kunoreva mwero wekuti kugona kuratidza kwechinhu chakadhindwa pamusoro pechiedza chechiitiko chiri pedyo nekukwanisa kutarisisa kwakazara.Kupenya kwezvinhu zvakadhindwa kunonyanya kutariswa nezvinhu zvakaita sebepa, ingi, kudzvanywa kwekudhinda uye post-press processing.Ichi chinyorwa chinotsanangura kukanganiswa kweinki pakudhinda gloss, zvirimo kune shamwari referensi:
Iyo inki chinhu chinokanganisa kupenya kwechinyorwa
Iyo inonyanya kutsvedzerera kweiyo inki firimu, iyo inotarirwa nehunhu uye uwandu hwekubatanidza zvinhu.Ingi inofanira kunge iine pigment yakanaka yakapararira, uye iine viscosity yakakwana uye nekukasira kuomeswa nekukurumidza kudzivirira kupinda kwakanyanya kweanosunga mumapores emapepa.Uyezve, iyo ingi inofanirawo kuva fluidity yakanaka, kuitira kuti paumbwe yakatsetseka ingi firimu pashure kudhinda.
01 Ink Firimu Ukobvu
In bepa kunonyanyisa absorption ingi bhainda, akasara bhainda achiri akachengetwa ingi firimu, zvinogona zvinobudirira kuvandudza kupenya kwezvakadhindwa nyaya.Kana firimu reinki rakakora, ndiko kuwedzera kwasara kwekubatanidza zvinhu, ndiko kunobatsira pakuvandudza kupenya kwechinhu chakadhindwa.
Kubwinya kunowedzera nehupamhi hwemufirimu weinki, kunyange iyo inki yakafanana, asi kubwinya kwekudhinda kunoumbwa nekuchinja kwakasiyana kwepepa nehupamhi hwefirimu yeinki yakasiyana.Kana iyo inki firimu yakatetepa, kupenya kwepepa rakadhindwa kunoderera nekuwedzera kweiyo inki firimu ukobvu, izvo zvinodaro nekuti iyo inki firimu inovhara yepakutanga yakakwirira gloss yebepa pachayo, uye kupenya kweiyo inki firimu pachayo kunoderedzwa nekuda. kusvika pakutorwa kwepepa;Nekuwedzera zvishoma nezvishoma muhupamhi hwefirimu yeinki, kutorwa kwebhainda kunenge kwakazara, uye kuchengetwa kwepamusoro kwebhainda kunowedzera, uye kupenya kuri kuwedzerawo.
Kupenya kweakavharidzirwa paperboard kudhinda kunowedzera nekukurumidza nekuwedzera kweinki firimu ukobvu.Mushure meiyo inki firimu ukobvu hunowedzera kusvika 3.8μm, kupenya hakuchawedzera nekuwedzera kweinki firimu ukobvu.
02 Ink Fluidity
The fluidity of inki yakakura kwazvo, dot kuwedzera, imprinting size kuwedzera, inki layer kutetepa, kudhinda gloss kwakashata;Ingi fluidity idiki zvakanyanya, yakakwira gloss, inki haisi nyore kutamisa, haikodzeri kudhinda.Nokudaro, kuti uwane gloss zviri nani, inofanira kudzora fluidity yeinki, kwete yakakura haigoni kuva duku.
03 Ink Leveling
Mukudhinda, kutsvedzerera kweinki kwakanaka, kupenya kwakanaka;Kusamira zvakanaka, kudhirowa kuri nyore, kupenya kusina kunaka.
04 Ink Pigment Content
Ink pigment content yakakwira, mufirimu yeinki inogona kuumba nhamba huru yediki capillaries.Kugona kwenhamba huru idzi dzemacapillaries madiki kuchengetedza binder kwakakura kudarika kugona kwebepa pamusoro pefiber gap kutora binder.Naizvozvo, kana ichienzaniswa neingi ine pigment yakaderera, ingi ine pigment yakakwira inokwanisa kuita kuti firimu reinki rirambe riine mabhandi akawanda.Kupenya kwemaprints uchishandisa ingi yepigment yepigment yakakwira kupfuura iyo yemaprints ane low pigment content.Naizvozvo, inki pigment zvidimbu zvakaumbwa pakati pe capillary network chimiro ndicho chinhu chikuru chinokanganisa kupenya kwezvinhu zvakadhindwa.
Muchidhindo chaicho, kushandiswa kwechiedza chemafuta nzira yekuwedzera kupenya kwekudhinda, iyi nzira yakasiyana zvachose neyo nzira yekuwedzera pigment yemukati inki.Iyi nzira mbiri dzekuwedzera kupenya kwezvinhu zvakadhindwa mukushandisa, maererano nekuumbwa kweinki uye kudhinda ingi firimu ukobvu.
Iyo nzira yekuwedzera pigment yemukati inogumira nekuda kwekudiwa kwekuderedzwa kwemavara mukudhinda kwemavara.Ingi yakagadzirwa nezvidimbu zvidiki zve pigment, apo pigment yemukati inoderedzwa kana kudhinda kupenya kuchaderedzwa, chete kana iyo ingi firimu iri gobvu kuburitsa kupenya kwepamusoro.Nokudaro, munyaya iyi, nzira yekuwedzera pigment content inogona kushandiswa kuvandudza kupenya kwezvinhu zvakadhindwa.Nekudaro, huwandu hwepigment hunogona kungowedzerwa kune imwe muganhu, zvikasadaro zvichave nekuda kwe pigment zvimedu hazvigone kuvharwa zvizere nebinder, kuitira kuti chiedza chepamusoro chekuparadzira chiitiko cheingi firimu chiwedzere asi chinotungamira kuderera kupenya. yezvakadhindwa.
05 Hukuru uye Kupararira kwePigment Particles
Ukuru hwe pigment particles munharaunda yekupararira inogadzirisa zvakananga mamiriro e capillary yefirimu yeinki.Kana ingi zvidimbu zvikaita weti, mamwe madiki capillaries anogona kuumbwa.Wedzera kugona kweinki firimu kuchengetedza binder uye kunatsiridza kupenya kwezvinhu zvakadhindwa.Panguva imwecheteyo, kana pigment particles ikapararira zvakanaka, inobatsirawo kugadzira firimu reinki rakatsetseka, iro rinogona kuvandudza kupenya kwezvinhu zvakadhindwa.Izvo zvinomisa zvinhu zvinokanganisa kupararira kwe pigment particles ndeye pH kukosha kwe pigment particles uye zviri mukati mezvinhu zvinoputika muinki.Iyo pH kukosha kwe pigment yakaderera, zviri mukati mezvinhu zvinoputika muinki zvakakwirira, uye kupararira kwe pigment particles kwakanaka.
06 Ink Transparency
Mushure mekugadzirwa kwepamusoro-soro yeingi firimu, chiitiko chechiedza chinoratidzwa nepamusoro peingi firimu, chimwe chikamu chepamusoro pepepa, uye chikazoratidzwa kunze, zvichiita maviri sefa yemavara, iyi yakaoma reflection rich color effect;Uye iyo ingi firimu inoumbwa neopaque pigment, kupenya kwayo kunongoratidzwa nepamusoro pepamusoro, iyo luster mhedzisiro haina kujeka inki.
07 Kubatanidza Material Smooth
Kupenya kwebhainda ndicho chinhu chikuru cheinki imprinting luster.Early inki binder inonyanya kuenderana nemafuta e-linseed, tung mafuta, catalpa mafuta uye mamwe mafuta emiriwo.Kutsvedzerera kwekuseri kwepamusoro pe conjunctiva hakuna kukwirira, firimu remafuta chete, kupararira kwechiedza chechiitiko, uye kupenya kwekudhinda kwakashata.Uye ikozvino inki linker resin sechinhu chikuru, yakadhindwa conjunctiva mushure mekutsvedzerera kwepasi kwakakwira, chiitiko chechiedza chinopararira kuratidza chinodzikiswa, uye kupenya kwakadhindwa kwakapetwa kakawanda kupfuura inki yekutanga.
08 Kupinda kwe Solvent
Kudhinda kuchangopera, nekuda kwekuomeswa kweinki nekugadzirisa hakuna kupera, saka, kupenya kwenzvimbo yekudhinda kwakakwira zvakanyanya, senge bepa rakavharwa, nzvimbo yayo yekudhinda yemunda chikamu che gloss inowanzo 15-20 madhigirii akakwirira. kupfuura pepa jena, uye pamusoro pacho pakanyorova uye kupenya.Asi iyo ingi painooma uye ichiomesa, kupenya kunoderera zvishoma nezvishoma.Kana iyo inonyungudutsa muinki ichiri kugara pabepa, iyo ingi inochengetedza dhigirii yemvura uye ine kutsetseka kwepamusoro.Zvisinei, nekupinda kwezvinonyungudutsa mupepa, kutsetseka kwepamusoro kunotarirwa nepigment particles, uye panguva ino pigment particles yakakura kudarika mamorekuru anonyungudutsa, naizvozvo, kutsetseka kwenzvimbo yekudhinda kune kupinda kwezvinonyungudutsa uye zvaifanira kudzikira.Muchiitiko ichi, iyo solvent inopinda muzinga inobata zvakananga kutsetseka uye kupenya kwenzvimbo yekudhinda.Kana kupinza kunoitwa zvishoma nezvishoma, uye oxidation polymerization yeresin inoitwa panguva yakakodzera, iyo inki yepamusoro inogona kuchengetedzwa muhunyoro hwakatsetseka hwemamiriro ekuoma kwefirimu.Nenzira iyi gloss yekudhinda inogona kuchengetedzwa pamwero wepamusoro.Pane zvinopesana, kana kupinza kwechigadzirisi kuchikurumidza, ipapo kuomeswa kwepolymerization kweresin kunogona kupedzwa chete kana kutsetseka kwenzvimbo yekudhinda kwakaderedzwa zvikuru, kuitira kuti kudhinda gloss kuderedzwa zvakanyanya.
Nokudaro, muchiitiko chekupenya kwakafanana kwepepa, zvishoma nezvishoma kupinza kweinki, kunowedzera kubwinya kwekudhinda.Kunyangwe mune iyo chena gloss uye inki yekupinda mwero zvakafanana, kudhinda gloss kuchave kwakasiyana nekuda kweinki pamapepa ekupinda mamiriro.Kazhinji, panguva imwechete yekupinda, dense uye yakanaka kupinza nyika inonyanya kubatsira pakuvandudzwa kweinodhinda gloss kupfuura nzvimbo shoma uye yakaoma yekupinda.Asi kuderedza ingi kupinda uye conjunctiva kumhanya kunatsiridza kupenya kuchaita kuti kuseri kunonamira ingi kukundikana.
09 Ink Drying Fomu
Iyo imwe chiyero cheinki ine mafomu akasiyana ekuomeswa, kupenya hakuna kufanana, kazhinji oxidized conjunctiva kuomesa pane osmotic drying gloss yakakwirira, nekuti oxidized conjunctiva inoomesa ingi firimu bonding zvinhu.
