Los ntawm cov qauv kev tsim cov ntawv sau thiab cov phaj ua, txoj kev luam ntawv yooj yim ntawm tus kheej yog nyob ntawm nws tus kheej thiab muaj nws cov cim tshwj xeeb. Cov phaj ua cov txheej txheem no yeej muaj raws li nram no: daim pib → hluav taws xob sib cais los yog cov duab thaij duab → cov duab tsis zoo → rov qab kis tau → lub cev raug → cov dej ntub dej → Tshaj xo → kev kho mob tom qab → Tshaj tawm tom qab → Muab tshuaj. Piv nrog rau offset luam, muaj cov nram qab no sib txawv:
1. Ib chav ntawm cov xim muaj nuj nqis uas tuaj yeem tsim tawm tau. Offset luam tawm yog 1% rau 99% (los yog 2% rau 98%), thiab luam ntawv flexo yog 3% mus rau 95%.
2. Lub qhov hluav taws xob tau nthuav dav (50%). Offset luam tawm yog 15% mus rau 20%, flexo printing yog 30% mus rau 40%
3. Tawm ntawm cov kab kev tshuaj ntsuam. Offset luam ntawv yog feem ntau nce mus txog 175 lines / inch, thiab cov flexo screens feem ntau tsis tshaj 150 tawm kab / nti.
Dimensional deformation ntawm cov xim sib cais
Qhov cuab tseem ceeb tshaj plaws ntawm cov phom nyuab yog qhov tseem ceeb. Thaum lub phom nyhuv rau ntawm lub cylindrical nruas, cov ntawv xov xwm ua rau lub cev ua rau cov menyuam yaus hauv lub qhov quav. Qhov deformation no cuam tshuam txog cov qauv thiab cov ntawv nyeem ntawm cov nplai ntawm cov ntawv luam tawm, yog li ntawd cov duab luam tawm tau luam tawm. Cov ntawv nyeem tsis tuaj yeem tsim ua kom raug, los sis txawm tias deformed. Yuav kom them nyiaj rau cov duab ntawm daim duab deformation, nws yog qhov tsim nyog los txo qhov loj ntawm qhov sib thooj ntawm cov duab tsis zoo. Tus qauv tsim ntawm kev sib txawv los yog xim sib txawv ua ntej phaj kev tsim nyog yuav tsum ua rau hauv tus account elongation ntawm lub phaj luam ntawv, thiab rho tawm qhov nqi sib txawv ntawm qhov ntev ntawm qhov ntev ntawm qhov uas yuav tsum tau them kom them, kom cov ntawv luam tawm tau raws li qhov yuav tsum tau ua.
Yooj yim version ntawm dot kis tau tus mob
1. Vim li cas rau qhov kev nthuav tawm ntawm cov muag khoom
Kev nthuav ntawm cov ntawv teev lus hauv kev luam yog kev tsis pom zoo, thiab muaj ob lub ntsiab lus tseem ceeb rau kev nthuav dav ntawm cov teev tseg: ib qho yog vim li cas lub cev. Thaum lub sij hawm ntawm lub teeb meem, tus cwj mem ntawm cov phaj dot yog deformed los ntawm kev ua yeeb yam, ua rau lub ntsiab lus kom nthuav; Lwm qhov laj thawj yog qhov ua rau lub teeb ci ntsa iab rau ntawm ib feem ntawm qhov ntawm cov duab thaij duab, qhov no ua rau pom qhov pom tau ntau npaum li cas. Qhov nthuav dav ntawm qhov muag pom tau yog nyob ntawm lub hau ntawm tus cwj pwm, qhov smoothness ntawm daim ntawv, nqus khoom, thiab cov zoo li.
2. Saj zawg zog version of dot kis tau tus mob
Hauv flexographic luam ntawv, vim cov duab ci ximxoo siv los kuj yog ib qho tseemceeb, nws tsim nyog siv lub tshuab luam tawm cov txheej txheem luam ntawv, uas ua rau cov duab ntawm cov duab teeb thiab cov duab ntawm cov duab, ua rau muaj kev hloov xim thiab txheej kev ua tiav. Hauv kev xyaum, los ntawm kev ntsuas thiab teeb duab qhov sib txawv ntawm tus qauv flexographic luam ntawv curve, nws yuav pom tau tias qhov dot loj nyob rau hauv cov ntawv luam theej luam yooj yim heev, thiab cov teev hauv qab 10% tsis yooj yim los tswj. Yog li ntawd, kev kho tshwj xeeb yuav tsum ua rau thaj tsam tseem ceeb, thiab kom deb li deb tau zaum taj.
3. cuam tshuam yam tseem ceeb
(1) Tus lej ntawm cov vijtsam ntau ntxiv. Qhov ntau ntawm cov npo ntawm cov npo, qhov loj hauv lub network yuav loj tuaj.
(2) Qhov loj ntawm lub tshuab luam ntawv, qhov loj dua qhov kev siv luam ntawv, qhov loj tshaj qhov teebmeem loj, thiab "zero zero" yuav tsum khaws cia kom ntau li ntau tau hauv cov ntawv luam tawm.
