Cov ntawv luam tawm cov khoom lag luam uas siv rau hlau logo ntawv nplaum, electroform nickel sticker, hlau foils thiab lwm yam ntaub ntawv raws li substrates yog hu ua hlau kos npe luam ntawv. Nyob rau hauv cov txheej txheem ntawm hlau kos npe luam ntawv, nws yog feem ntau ntsib tias muaj xim sib txawv ntawm cov ntawv luam tawm. Cov hauv qab no yog cov lus qhia luv luv rau txoj kev tswj ntawm chromatic aberration nyob rau hauv cov txheej txheem ntawm hlau luam ntawv cim:
Nyob rau hauv cov txheej txheem ntawm cov hlau kos npe luam ntawv, xim txawv ntawm cov khoom luam tawm feem ntau suav nrog: number case khoom xim sib txawv, sib tshooj xim sib txawv, dot deformation xim sib txawv, xim txawv los ntawm qhov tsis raug overprinting, xim txawv los ntawm kev txawv txav wetting system, xim kos npe. printing thiab glazing ntau lawm txheej txheem. chromatic aberration, thiab lwm yam.
1. Cov xim sib txawv ntawm tus cwj mem: xws li cov xim thawj lossis xim xim xim, lub ntsiab yog vim li cas rau xim sib txawv ntawm cov khoom tom qab yog: 1. Cov xim thiab xim tsis muaj tseeb, hom thiab feem ntau ntawm tus number case xaiv yog tsis tsim nyog, thiab lawv tsis tuaj yeem ua tau raws li cov kev cai luam ntawv; 2. Lub tshuab luam ntawv ntawm tus number case yog txawv ntawm Kev ua haujlwm ntawm lub tshuab luam ntawv thiab lub tshuab ziab khaub ncaws tsis haum; ③ Tus number case xim thiab lub thickness ntawm tus number case txheej tsis haum los yog tus number case loj.
Txoj kev tswj hwm: ① sau cov ntaub ntawv thaum lub sij hawm luam ntawv tiag tiag ntawm cov txheej txheem hlau, qhia meej meej, thiab tswj tus nqi ntawm lub tshuab luam ntawv; ② Kev luam ntawv tsim nyog ntawm tus number case yuav tsum ua tau raws li lub hom phiaj ntawm kev luam ntawv, thiab cov viscosity ntawm tus number case yuav tsum yog, fluidity yuav tsum tau kho raws li qhov xwm ntawm substrate, ceev ntawm lub tshuab, thiab hom duab thiab cov ntawv nyeem. . Lub tshuab ceev yog ceev thiab cov khoom luam ntawv yuav tsum tau. Lub viscosity ntawm tus number case yog me me thiab fluidity kuj loj, thiab vice versa; ③ Thaum tus number case tau npaj thawj zaug, cov qauv luam ntawv yuav tsum tau siv raws li tus qauv. txheem hauv paus.
2. Overlay chromatic aberration: nrog rau cov kab sib txuas thiab cov khoom hauv qab, cov laj thawj tseem ceeb ntawm cov chromatic aberration yog: ① Cov xim sib txawv ntawm cov xim tsis tsim nyog; ② Cov kua nplaum viscosity tsis ruaj khov.
Tswj txoj kev: ① Tswj lub thickness ntawm tus number case txheej thiab viscosity ntawm tus number case; ② Npaj cov ntawv luam ntawm cov cim hlau kom tsim nyog: feem ntau, cov xim thib ob yog luam tawm ua ntej, thiab cov xim tseem ceeb yog luam tawm tom qab. Cov xim nrog cov ntsiab lus qis qis yog luam tawm ua ntej, xim nrog cov ntsiab lus siab yog luam tawm tom qab, anilox version yog luam tawm ua ntej, thiab cov phaj khoom tau luam tawm tom qab. Tus cwj mem uas muaj viscosity siab yog luam tawm ua ntej, xim tsaus yog luam tawm ua ntej, thiab lub teeb xim yog luam tawm tom qab. Cov duab me me thiab cov ntawv nyeem tau luam tawm ua ntej, thiab cov uas muaj duab loj thiab cov ntawv nyeem tau luam tawm tom qab. Cov xim tsaus yog luam tawm ua ntej, thiab cov ci ntsa iab yog luam tawm tom qab. Qhov tseeb, nws yog ib qho tsim nyog los kho cov xim sib txawv raws li cov ntsiab lus sib txawv thiab cov yam ntxwv; ③ kho cov kav dej thiab cov kav dej, thiab tswj cov lej sib npaug.
3. Dot deformation chromatic aberration: Lub ntsiab yog vim li cas rau dot deformation chromatic aberration yog: ①Qhov nce los yog txo cov neeg kho tshuab dots, nrog rau kev cuam tshuam ntawm kev luam ntawv siab, number case, dej phwj, pam, hlau phaj txheej txheej, thiab lwm yam.; ②Qhov kev nce ntawm cov dots kho qhov muag los yog shrinking, uas yog hais txog kev hloov ntawm cov dots nyob rau hauv tus txheej txheem ntawm kev hloov cov luam ntawv tsis zoo ntawm cov hlau kos npe rau PS version.
Txoj kev tswj hwm: ① Kho lub siab kom ua tau raws li cov kev cai luam ntawv. Yog tias lub siab loj dhau lawm, lub phaj hlau yuav nthuav dav hauv cov duab thiab cov ntawv, thiab yog tias qhov ntsuas qhov ntsuas tsis meej, nws yuav ua rau lub phaj poob, uas yuav cuam tshuam rau kev luam ntawv durability. Yog tias qhov siab me dhau lawm, lub phaj luam ntawv muaj cov inking tsis zoo, tsis zoo imprint txhais, thiab khoob dots; ② Tswj lub viscosity ntawm tus number case; ③ Tswj tus nqi pH thiab tus nqi conductivity ntawm cov kav dej; ④ Kev teeb tsa ntawm daim pam ua tau raws li cov qauv los tiv thaiv daim pam ntawm kev ncab, Dot hloov los ntawm torsion lossis compression deformation; ⑤ Kev tswj xyuas meej ntawm lub sijhawm raug los xyuas kom muaj kev rov qab los ntawm qhov tsis zoo.
4. Qhov sib txawv xim tshwm sim los ntawm qhov tsis raug overprinting feem ntau yog tshwm sim los ntawm qhov tsis raug qhov chaw ntawm txhua xim version thaum lub sij hawm overprinting txheej txheem.
Kev tswj cov txheej txheem: ①Qhov kev hloov siab ua tau raws li qhov yuav tsum tau muaj ntawm cov ntawv hlau luam ntawv, suav nrog ntau yam ntaub qhwv; ② Lub ntsuas phoo pem hauv ntej, sab ntsuas, thiab gripper yog qhov chaw raug; ③ Kev teeb tsa ntawm PS version ua raws li cov cai; ④ Cov ntawv luam loj rov qab ua cov yeeb yaj kiab loj; Qhov tseeb qhov chaw; ⑥ Qhov tseeb qhov tseeb ntawm cov hlau kos npe tsim ua raws li lub teb chaws cov qauv thiab kev ua haujlwm ntawm cov khoom siv.
