Tus cwj pwm ntawm tus cwj mem uas cuam tshuam rau gloss ntawm kev luam ntawv
Nws yog tsuas yog qhov smoothness ntawm tus number case zaj duab xis, uas yog txiav txim los ntawm qhov xwm thiab kom muaj nuj nqis ntawm cov khoom sib txuas.Ink yuav tsum muaj cov xim zoo sib xws, thiab muaj cov viscosity txaus thiab ziab kom ceev kom tsis txhob nkag mus rau hauv cov ntaub ntawv ntau dhau rau hauv daim ntawv pores.Tsis tas li ntawd, tus number case yuav tsum muaj fluidity zoo, thiaj li tsim kom muaj tus cwj mem zoo tom qab luam ntawv.
01 Ink Film Thickness
Nyob rau hauv daim ntawv siab tshaj plaws absorbing number case binder, qhov seem binder tseem khaws cia nyob rau hauv tus cwj mem zaj duab xis, nws tuaj yeem txhim kho cov luster ntawm cov ntawv luam tawm.Lub thicker tus cwj mem zaj duab xis, ntau cov khoom sib txuas ntxiv, qhov zoo dua rau kev txhim kho cov luster ntawm cov ntawv luam tawm.
Gloss nce nrog lub thickness ntawm tus number case zaj duab xis, txawm hais tias tus number case yog tib yam, tab sis cov ntawv luam ntawv gloss tsim los ntawm cov ntawv sib txawv hloov nrog lub thickness ntawm tus number case zaj duab xis yog txawv.Thaum tus number case zaj duab xis yog nyias, qhov ci ntawm cov ntawv luam tawm txo qis nrog qhov nce ntawm tus number case zaj duab xis thickness, uas yog vim li cas tus number case zaj duab xis npog qhov qub siab dua gloss ntawm daim ntawv nws tus kheej, thiab lub gloss ntawm tus number case zaj duab xis nws tus kheej raug txo vim. mus rau qhov nqus ntawm daim ntawv;Nrog rau qhov maj mam nce hauv cov tuab ntawm cov yeeb yaj kiab, qhov nqus ntawm cov ntaub ntawv yog qhov yooj yim saturated, thiab qhov chaw tuav ntawm cov ntaub ntawv yog nce, thiab cov gloss kuj tseem txhim kho.
Lub gloss ntawm coated paperboard luam ntawv nce sai nrog qhov nce ntawm number case zaj duab xis thickness.Tom qab tus number case zaj duab xis thickness nce mus rau 3.8μm, lub gloss yuav tsis nce ntxiv nrog rau qhov nce ntawm number case zaj duab xis thickness.
02 Ink Fluidity
Lub fluidity ntawm tus number case yog loj heev, dot nce, imprinting loj expansion, number case txheej thinning, printing gloss yog tsis zoo;Ink fluidity tsawg dhau, siab gloss, number case tsis yooj yim rau kev hloov, tsis haum rau luam ntawv.Yog li ntawd, thiaj li yuav tau txais gloss zoo dua, yuav tsum tswj cov fluidity ntawm tus number case, tsis loj heev tsis tuaj yeem me dhau.
03 Ink Leveling

04 Ink Pigment Cov ntsiab lus
Ink pigment ntsiab lus yog siab, nyob rau hauv tus number case zaj duab xis yuav tsim ib tug loj tus naj npawb ntawm me me capillaries.Lub peev xwm ntawm cov neeg coob ntawm cov me me capillaries khaws cov ntaub ntawv yog ntau dua li qhov muaj peev xwm ntawm daim ntawv saum npoo fiber ntau kom nqus tau cov ntaub ntawv.Yog li ntawd, piv nrog tus cwj mem nrog cov ntsiab lus tsis tshua muaj xim, tus cwj mem nrog cov ntsiab lus pigment siab tuaj yeem ua rau tus cwj mem zaj duab xis khaws cov binders ntau dua.Lub gloss ntawm prints siv high pigment cov ntsiab lus inks yog siab dua li ntawm prints uas tsis muaj xim ntsiab lus.Yog li ntawd, cov xim pleev xim xim tsim los ntawm cov qauv capillary network yog qhov tseem ceeb cuam tshuam rau cov luster ntawm cov ntawv luam tawm.
Hauv kev luam ntawv tiag tiag, kev siv lub teeb roj txoj kev los ua kom cov luster ntawm cov ntawv luam tawm, txoj kev no txawv kiag li los ntawm txoj kev nce cov xim ntawm tus number case.Ob txoj hauv kev no txhawm rau ua kom cov luster ntawm cov ntawv luam tawm hauv daim ntawv thov, raws li qhov muaj pes tsawg leeg ntawm number case thiab luam ntawv number case zaj duab xis thickness.
Cov txheej txheem ntawm cov ntsiab lus pigment yog txwv vim qhov xav tau ntawm cov xim txo cov xim luam ntawv.Ink npaj nrog me me ntawm cov xim, thaum cov xim cov ntsiab lus raug txo thaum cov ntawv luam tawm yuav raug txo, tsuas yog thaum tus number case zaj duab xis yog tuab heev los tsim kom muaj luster ntau dua.Yog li ntawd, nyob rau hauv cov ntaub ntawv no, tus txheej txheem ntawm nce pigment ntsiab lus yuav siv tau los txhim kho cov luster ntawm cov ntaub ntawv luam.Txawm li cas los xij, cov xim ntawm cov xim tsuas yog nce mus rau qee qhov kev txwv, txwv tsis pub nws yuav yog vim cov xim pigment tsis tuaj yeem npog tag nrho los ntawm cov ntawv khi, yog li ntawd lub teeb tawg ntawm qhov tshwm sim ntawm tus number case zaj duab xis yog intensified tab sis ua rau txo qis luster. ntawm cov ntawv luam tawm.
05 Qhov Loj thiab Dispersion ntawm Pigment Particles
Qhov loj ntawm pigment hais nyob rau hauv lub dispersion xeev ncaj qha txiav txim lub xeev ntawm capillary ntawm tus number case zaj duab xis.Yog hais tias tus cwj mem particle tso zis, ntau me me capillaries tuaj yeem tsim.Ua kom muaj peev xwm ntawm cov yeeb yaj kiab number case khaws cia thiab txhim kho cov luster ntawm cov ntawv luam tawm.Nyob rau tib lub sijhawm, yog tias cov xim pigment disperse zoo, nws kuj tseem pab tsim kom muaj cov xim zoo nkauj, uas tuaj yeem txhim kho cov luster ntawm cov ntawv luam tawm.Qhov txwv tsis pub cuam tshuam rau kev tawg ntawm cov xim pigment yog pH tus nqi ntawm cov xim pigment thiab cov ntsiab lus ntawm cov teeb meem tsis zoo hauv tus cwj mem.Tus nqi pH ntawm cov xim tsis tshua muaj, cov ntsiab lus ntawm cov tshuaj tsis haum rau hauv tus number case yog siab, thiab dispersion ntawm cov xim pigment yog qhov zoo.
06 Ink Transparency

08 Kev Txhaum Cai
Kev luam ntawv tsuas yog tas lawm, vim tias cov number case qhuav thiab kho tsis tiav, yog li ntawd, lub gloss ntawm lub tshuab luam ntawv yog siab heev, xws li cov ntawv coated, nws cov ntawv luam tawm ntawm daim teb ib feem ntawm gloss feem ntau yog 15-20 degrees siab dua. tshaj li ntawm daim ntawv dawb, thiab nto yog ntub thiab ci.Tab sis raws li tus number case dries thiab solidifies, lub gloss maj mam txo.Thaum cov kuab tshuaj nyob rau hauv tus number case tseem nyob rau ntawm daim ntawv, tus number case tuav ib tug degree ntawm fluidity thiab muaj ib tug siab smoothness.Txawm li cas los xij, nrog kev nkag mus ntawm cov kuab tshuaj rau hauv daim ntawv, qhov smoothness ntawm qhov chaw yog txiav txim siab los ntawm cov xim pigment, thiab lub sijhawm no cov xim pigment yog loj dua li cov kuab tshuaj molecules, yog li ntawd, qhov smoothness ntawm cov ntawv luam tawm yog nrog rau cov khoom siv. nkag mus ntawm cov kuab tshuaj thiab yuav tsum tau poob.Nyob rau hauv cov txheej txheem no, cov kuab tshuaj nkag mus ncaj qha cuam tshuam rau smoothness thiab gloss ntawm printing nto.Yog hais tias qhov infiltration yog nqa tawm maj mam, thiab oxidation polymerization ntawm cov cob yog nqa tawm ntawm qhov tsim nyog ceev, tus number case nto tuaj yeem khaws cia rau hauv ib qho kev sib luag ntawm lub xeev ntawm zaj duab xis hardening.Nyob rau hauv txoj kev no lub tshuab luam ntawv gloss tuaj yeem tswj tau ntawm qib siab dua.Ntawm qhov tsis sib xws, yog tias qhov nkag mus ntawm cov kuab tshuaj yog nrawm, tom qab ntawd cov polymerization hardening ntawm cov resin tsuas tuaj yeem ua tiav thaum lub smoothness ntawm lub tshuab luam ntawv tau txo qis heev, yog li cov ntawv luam tawm gloss yog txo qis.
Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm tib lub gloss ntawm daim ntawv, lub qeeb nkag mus ntawm tus number case, lub siab dua lub gloss ntawm printing.Txawm tias nyob rau hauv cov ntaub ntawv ntawm dawb gloss thiab number case nkag mus yog tib yam, luam ntawv gloss yuav txawv vim tus number case ntawm daim ntawv nkag mus rau lub xeev.Feem ntau, ntawm tib tus nqi nkag siab, ntom thiab zoo thiab zoo rau kev nkag mus rau kev txhim kho cov luam ntawv tshaj li lub xeev thiab ntxhib lub xeev.Tab sis txo tus number case nkag thiab conjunctiva ceev los txhim kho kev luam ntawv gloss yuav ua rau backside sticking number case tsis ua hauj lwm.
09 Ink Drying Form
Tib tus number case nrog cov ntaub ntawv ziab sib txawv, qhov gloss tsis zoo ib yam, feem ntau oxidized conjunctiva drying dua osmotic drying gloss yog siab, vim oxidized conjunctiva qhuav ink zaj duab xis bonding khoom.
