Hnov xim kua cwj mem yog ib tus qauv tshiab rau plaub hom xim. Nws yog hais txog tus cwj pwm tshiab nrog rau ib los yog ob hom kev xav thiab ntxiv nrog lwm cov ntaub ntawv pov thawj. Teem rau cov kev xav tau luam tawm thiab xim nqaij tawv. Cov xim gamut ntawm qhov chaw xim yog deb tshaj ntawm ntau yam xim gamut ntawm rgb thiab cmyk. Ntau yam xim uas tsis tuaj yeem pom tshwm ntsej muag los ntawm cmyk plaub-xim ntawv number case muaj peev xwm pom tau hais nrog cov xim muaj xim. Vim hais tias qhov chaw xim xim siv qhov loj ntawm cov xim xim txheej xim, cov xim zoo yog qhov zoo, thiab cov xim sib txawv ntawm qhov dot overprinting thiab dot deformation txo, xim yog ruaj khov, thiab cov xim gamut yog dav. Yog li ntawd, thiaj li ua tiav cov teeb meem tshwj xeeb hauv cov ntawv luam yeeb, cov ntawv ua muaj ntawv caw thiab cov khoom ntim, cov xim tshwj xeeb cov xim siv rau kev luam ntawv. Kev pom xim luam ntawv tsis tuaj yeem yog daws cov teeb meem plaub-xim ntawm kev tshaj saud thiab tus lej tshuav nqi, tiam sis tseem ua tau raws li qhov tsim nyog ntawm kev tsim tshiab, thiab tus lej-thiab-ntxuav tshuav hauv cov txheej txheem luam ntawv kuj yoojyim.
Muaj ntau ntau yam uas ua rau cov xim txawv ntawm qhov xim muaj xim xim, tiam sis feem ntau yog: cov khoom ntawm cov khoom, qhov ntawm tus cwj mem, cov xwm txheej luam tawm, thiab qhov xaus ntawm cov ntawv luam tawm. Tej yam zoo li no tuaj yeem cuam tshuam rau cov xim luam yeeb thaum lub sij hawm qhov xim xim luam ntawv.
Ua ntej, tus txheej txheem ntawm cov ntawv luam tawm (daim ntawv) ntawm cov xim ntawm tus cwj pwm
1, daim ntawv xaj
Cov yam cuam tshuam rau lub whiteness ntawm daim ntawv yog: 1 Whiteness ntawm slurry: qhov tseem ceeb tshaj plaws. 2 Dyes: Lub zuag yuav tsum tau xaiv kom nws tsis txhob cuam tshuam nws cov kev xav nyob ze ntawm lub ntsiab lus ntawm qhov ntsuas ntawm qhov ntsuas, qhov ntawd yog, nws tsis cuam tshuam qhov dawb ntawm daim ntawv. 3 cov tub luam: nyob ntawm nws hom thiab qib. 4 Txheej Txheem: Lub ntsiab lus ntawm cov ntawv luam tawm xim dawb yog txiav txim siab los ntawm cov ntaub ntawv ntawm lub hauv paus, lub ntsiab lus ntawm cov txheej, thiab cov txheej txheej. Cov ntaub ntawv uas muaj xim dawb thiab ib qho xim (yog muaj ntawv xiav thiab yellowish) muaj cov teebmeem txawv ntawm cov xim ntawm cov ntawv luam tawm plhaub. Rau tib hom ntawv ntawm daim ntawv dawb, lub whiteness yog txawv, tshwj xeeb tshaj yog rau cov xim nrog ntau tus nqi ci, cov nyhuv yog tshwj xeeb pom tseeb, thiab qhov piv ntawm qhov xim xim kua cwj mem txawv heev. Yog li ntawd, nyob rau hauv qhov ntau lawm, daim ntawv nrog tus xiv dawb yuav tsum tau siv ntau li ntau tau los txo tus cwj pwm ntawm daim ntawv dawb ntawm daim luam xim.
2, smoothness thiab gloss ntawm daim ntawv
Los ntawm kev cuam tshuam rau qhov zoo ntawm cov teeb meem luam tawm, muaj kev sib raug zoo heev ntawm qhov ci ntawm daim ntawv thiab qhov ci ntawm cov luam. Txawm hais tias tsis muaj hom ntawm tus cwj pwm, qhov ci ntawm qhov sau tau nce nrog lub gloss ntawm daim ntawv nws tus kheej. Lub gloss ntawm daim ntawv no ncaj qha ntsig txog qhov inking efficiency ntawm daim ntawv. Cov ntaub ntawv uas muaj lub ci ntsa iab tuaj yeem ua tau zoo dua cov ntawv luam tawm thaum cov ntawv uas muaj qis dua tuaj yeem muaj tib lub cwj pwm xuab zeb tuab hauv daim ntawv. Yog li, muaj ib qho kev sib txheeb sib ze ntawm qhov ci ntawm cov luam thiab cov gloss ntawm daim ntawv nws tus kheej.
3, ntawv xaj lees txais thiab kev ua kom haum
Ink qhov kev lees paub hais txog qhov peev xwm ntawm daim ntawv ntaws kom tau txais tus lej hloov raws li nws tau luam tawm rau ntawm ib lub sijhawm thaum luam ntawv. Nws yog zoo ib yam nrog peb yam ntawm cov ntawv kev ua tau zoo: qhov peev xwm ntawm daim ntawv nto los tiv thaiv lub wetting ntawm lub luam ntawv number; qhov kev muaj peev xwm ntawm daim ntawv ntws mus nqus qee yam khoom ntim quav; qhov peev xwm ntawm daim ntawv nto los tuav thiab tuav ib yam cwj mem zas duab. Cov ntaub ntawv-rau-ink-absorption kev ua tau tshwm sim dhau lub sijhawm ntev los ntawm tus lej rau daim ntawv hu rau kom tiav solidification rau ntawm daim ntawv. Nws absorbs lub Cheebtsam qis-viscosity ntawm tus number case nrog cov capillary pores ntawm daim ntawv thiab ib co Cheebtsam ntawm tus number case. Internal osmosis muaj feem xyuam. Kev luam tawm siab, luam sij hawm, ink number case viscosity, thiab daim ntawv hluav taws xob hlawv tag nrho yuav cuam tshuam rau daim ntawv muaj peev xwm nqus tau kua. Tib tug cwj mem yuav muaj ntau hom ntawv luam tawm thaum sau rau ntawm daim ntawv nrog absorbency sib txawv nyob rau hauv tib co kev mob. Muaj cov pore cov qauv ua rau saum npoo ntawm daim ntawv los ntawm ntau theem hauv cov ntsiab lus ntawm anisotropic. Thiaj li yuav tau txais kev ua zoo zoo thiab kev sib luag ntawm daim ntawv, cov coatings txawv thicknesses feem ntau yog siv rau ntawm daim ntawv. Qhov xwm txheej thiab txheej txheem ntawm txheej coating seb lub peev xwm ntawm daim ntawv deg kom nqus tau kua. Qhov txawv ntawm absorbency tau qhov sib txawv ntawm cov xim ntawm cov ntawv luam tawm plhaub txheej.
Thib ob, qhov tshwm sim ntawm qhov cim ntawm tus cwj mem ntawm cov xim
Cov nyhuv kawg ntawm cov ntawv luam tawm yog muaj feem xyuam nrog rau tus cwj pwm ntawm lub cev thiab tshuaj lom neeg. Cov dadej ntawm tus lej txiav txim seb qhov xwm ntawm tus cwj pwm:
1, qhov loj ntawm cov xim pigment thiab qhov degree ntawm dispersion
Txawm hais tias lub luag hauj lwm ntawm tus cwj pwm kos duab capillary yog ib qho tseem ceeb hauv kev tsim cov gloss ntawm cov luam, qhov loj qhov pigment particle hauv lub xeev dispersed tseem ceeb dua, uas ncaj qha txiav txim lub xeev cov capillary ntawm tus cwj pwm film. Yog li, cov xim pigment yog me thiab zoo dispersed, uas yog ib qho kev zoo rau kev ua tus cwj pwm zaj duab xis, thiab yog ib qho tseem ceeb heev rau kev txhim kho cov gloss ntawm cov ntawv luam tawm.
2. Lub viscosity ntawm lub binder thiab cov ntsiab lus ntawm cov xim
Raws li cov kev sib txuas ntawm cov kab sib txuas, cov kab capillary permeation yog inversely ntsig txog cov viscosity ntawm cov kua, uas yog, tus kab permeation decreases li cov viscosity tsub kom. Lub capillary network qauv tsim ntawm tus number case pigment yog ib qho tseem ceeb ntawm txoj kev uas txiav txim siab kom cov paj ntaub ntawm cov luam. Thaum lub sij hawm ntawm lub teeb meem, tus number case yog nias rau hauv qhov loj qhov hws ntawm daim ntawv; tom qab luam, lub phom pib cais tawm ntawm tus number case thiab nkag mus rau hauv lub me pores ntawm daim ntawv. Yog li ntawd, qhov luaj li cas ntawm cov cuav zaj duab xis capillary txiav txim siab seb qhov sib cais ntawm tus tuav. Capillary retention ntawm lub binder yog zoo dua ntau tshaj li cov kev luam tawm siab mus nias lub binder rau hauv lub pores ntawm daim ntawv.
3, ziab lub sijhawm
Qhov ziab ziab ntawm cov cwj mem naj npawb rau hauv daim ntawv no yuav txo qhov nyiaj ntawm cov binder uas nkag mus rau hauv daim ntawv qhov ntxaij, qhov kev txhim kho cov gloss thiab smoothness ntawm tus cwj pwm film. Cov gloss siab ntawm tus cwj pwm ntawm cov yeeb yaj duab txhais tau hais tias cov qauv ntawm lub ntsej muag tseem ceeb heev, yog li ntawd tib neeg lub qhov muag pom tau tias lub teeb dawb reflected los ntawm cov nplaum yog ntau dua lub cuaj zaj duab xis nrog tsawg glossiness feem ntau, yog li ntawd qhov kev nplua nuj ntawm qhov xim yog siab dua. Yog li ntawd, cov ntawv sau nrog siab gloss zoo dua li thiab tag nrho. Cov ntawv luam tawm txheej ntawm qhov xim xim kua cawv yog feem ntau txhais los yog muaj teeb meem. Thaum xaiv mis mos, qhov cawv ntawm lub teeb ntawm lub teeb ntim rau ntawm cov xoom txheej rau ntawm qhov chaw xim luam tawm yuav tsum raug txiav txim siab raws li qhov xwm txheej tseeb.
