iindaba

Ngenxa yomahluko omkhulu kwindawo yoshicilelo lobushushu kunye nokufuma, iimeko inkqubo iipropati ezahlukeneyo kunye printability, uhlobo ngalunye inki pigment, ikhonkco esetyenziswa umlinganiselo wezinto kunye nokuzalisa imathiriyeli phantse rhoqo, ukuba akakwazi ukuhlangabezana imfuneko iimeko ezahlukeneyo zokufaneleka koshicilelo, izongezo ze-inki zokuprinta zinokudityaniswa ukunyenyisa i-inki ukuze ihlangabezane neemfuno zokufaneleka koshicilelo.Eli phepha lazisa ngokufutshane indima yezongezo ze-inki eziqhelekileyo kunye neendlela zabo zokusetyenziswa, umxholo wereferensi yabahlobo:

izongezo ze-inki

Ii-inki ezincedisayo zizixhobo ezincedisayo ezisetyenziselwa ukunyenyisa i-inki ukuze zihambelane neemeko ezahlukeneyo zokushicilela.Zininzi iindidi zezongezo ze-inki, incanyathiso esetyenziswa ngokuqhelekileyo, i-arhente yokufefa yokukhanya, i-desiccant, i-ejenti yokomisa kancinane, i-diluent, i-ejenti ekwaziyo ukumelana ne-friction, i-oyile yeglosi yokugquma, ukongeza kwezi zingentla zisetyenziswa ngokuqhelekileyo izongezo ze-inki, kukho i-anti-fouling agent, anti. -i-agent ye-foam, i-oyile yokushicilela, njl. Ukususela kwimbono yokuphucula ukusebenza kakuhle kunye nomgangatho wokushicilela, ngokweemeko eziguqukayo zokushicilela, kunenzuzo ukongeza ezinye izongezo ngokufanelekileyo kwiinki ezikhethiweyo ukuqinisekisa ukushicilelwa okuqhelekileyo.

01 Ukurhoxiswa kokuncamathelisa

I-Adhesives ine-viscosity encinci kwaye isetyenziswa ngokuqhelekileyo kwi-lithography kunye neenki zokushicilela zokunceda ukunciphisa i-viscosity yazo.Kushicilelo lwe-offset, ngenxa yotshintsho kwiipropathi zephepha kunye neemeko zokuprinta, njengokufunxa ioli, amandla aphantsi komhlaba, into entle kunye nengalunganga yokulahla i-coating, xa i-desiccant igqithise okanye ubushushu begumbi leworkshop yokushicilela buphantsi kakhulu, iya kuthi. kubangela iinwele zephepha, ipleyiti yesitaki sokuprinta, ipleyiti yokuncamathisela kunye nezinye iimpazamo, ezichaphazela umgangatho wokushicilela.Ngoko ke, xa kwenzeka le nto ingentla, inani elifanelekileyo le-adhesive yokususwa kwe-adhesive inokongezwa ukuba buthathaka kwaye isuse indima yeziphene ezingentla.

02 Ukusuka kwi-Arhente yokuKhanya

Susa i-diluent, eyaziwa ngokuba yi-diluent, sisixa esikhulu sezongezo zoshicilelo lwe-offset.Kukho i-diluent ezimbini eziqhelekileyo: enye ioli ecacileyo, isetyenziselwa i-inki eqaqambileyo;Enye i-resin - uhlobo lwe-diluent, esetyenziselwa i-inki ye-resin.Ukuba umbala we-inki yoshicilelo ufunyaniswa unzulu kakhulu ukubuyisela umbhalo-ngqangi wokuqala, unokongeza inani elifanelekileyo le-arhente yokukhanya, ukuze ifezekise umphumo ofanelekileyo.

03 Desiccant

I-Desiccant yenye yezona zinto zibalulekileyo zokushicilela i-inki encedisayo.Ngokweemeko ezahlukeneyo zokuprinta kunye nephepha lokushicilela, inani le-desiccant, uhlobo kunye nendlela yokusetyenziswa nayo ihluke.I-desiccant esetyenziswa ngokuqhelekileyo ioli ebomvu eyomileyo, ioli emhlophe eyomileyo iindidi ezimbini, ioli ebomvu eyomileyo iyomisa ukusuka ngaphandle ukuya ngaphakathi, ioli emhlophe eyomileyo ingaphandle ngexesha elifanayo lomile.Xa uprinta, ndikhetha uhlobo lweoli yokomisa ngokweemfuno zokuprinta kunye nombala we-inki.Idosi ye-oyile yokoma ngokubanzi yi-2% -3%, kakhulu iya kubuyisela umva, ukwenzela ukuba izinga lokumisa lihle.

04 Slow Drying Agent

I-Desiccant eyaziwa ngokuba yi-antioxidants, le yi-desiccant kunye nezongezo ze-inki ezichaseneyo.Kwinkqubo yoshicilelo, ngenxa yezizathu ezahlukahlukeneyo zidla ngokubangela ixesha lokuphumla, xa ixesha lokuphumla ixesha elide, inki iya komisa ulusu.Ukuze ucombulule olu hlobo lwengxaki, kudla ngokuyimfuneko ukongeza inani elifanelekileyo le-desiccant kwi-inki kumatshini, kwaye uqhube umatshini ngamaxesha ambalwa, ukwenzela ukuba ungakhawulezi ukoma.

05 Mncinci,

Ekushicileleni, ngenxa ye-viscosity ye-inki egqithisileyo okanye umgangatho wephepha ophantsi, iimpazamo ezifana nokutsalwa koboya bephepha kunye nokuwa kwepleyiti zihlala zisenzeka, ezichaphazela ukuprintwa okuqhelekileyo.Ngeli xesha, ukongeza ukongeza isixa esifanelekileyo sokuncamathelisa ukunciphisa i-viscidity ye-inki, isixa esincinci se-diluent singongezwa ukunciphisa i-viscidity ye-inki, ukuze ushicilelo luqhube kakuhle.Kukho iintlobo ezininzi ze-oyile ye-inki edibeneyo, i-viscosity ephantsi ye-inki ezintandathu.

06 Ukuxhathisa kwiFriction

I-arhente yokumelana nefriction ikwabizwa ngokuba yiarhente yokugudisa.Uninzi lwezi zinto zisekelwe kwizinto ze-wax.Xa amasuntswana e-inki yoshicilelo rhabaxa, ezifana inki emhlophe, igolide kunye nesilivere inki, yongeza isixa esifanelekileyo i-arhente ukumelana ukukhuhlana ukunyusa ukuxhathisa ukukhuhla kunye agudileyo izinto yoshicilelo.

07 I-Oli yokuKhanya yeCap

Iimpawu zokuthengisa, iialbham zemifanekiso kunye nezinye iimveliso zoshicilelo oluphezulu, umgangatho wokushicilela ubukhulu becala ngonyango lweglosi, ukuze kuphunyezwe isiphumo sokukhanya okuphezulu, ukusetyenziswa kweoli yeglosi, inokuxutywa kwi-inki yoshicilelo ngaphambi kokushicilela, inokuprintwa kwakhona emva kokushicilela. ioli yeglosi.Kodwa emva kokuprintwa kweglosi yeglosi, emva kwexesha elide kuya kuba tyheli, ukuchasana nokukhanya kubi, ke ngoku kukho iindlela ezininzi kwiglosi yeglosi yeoli entsha yokukhanya.
