Qhov txawv ntawm letterpress printing thiab screen printing yog dab tsi?

1, Kev sib piv ntawm Cov Ntsiab Cai
Letterpress printing: letterpress printing yog ib lub tshuab luam ntawv qub, uas nws lub hauv paus ntsiab lus tseem ceeb yog kos lossis tsim cov duab kos duab thiab cov ntaub ntawv ntawm qhov tsa ntawm lub phaj luam ntawv, thiab hloov tus number case ntawm qhov nce mus rau lub substrate los ntawm kev siv lub siab, yog li ua tiav cov ntawv luam ntawv. luam ntawv. Nyob rau hauv cov ntawv luam ntawv, cov duab thiab cov ntawv ntawm cov ntawv luam ntawv yog siab tshaj qhov tsis muaj duab, tsim lub xeev tsa, yog li lub npe "letterpress".
Screen printing: Screen printing yog ib hom stencil luam ntawv thev naus laus zis, uas siv cov mesh qhov ntawm lub vijtsam luam ntawv phaj kom xau number case los ntawm cov qhov mesh hauv cov duab thiab cov ntawv thiab muab nws tso rau saum npoo ntawm lub substrate los ntawm lub siab ntawm lub tshuab luam ntawv. number case scraper. Lub vijtsam luam ntawv phaj yog tsim los ntawm ib lub thav duab, ib qho screen, thiab txheej txheej photosensitive nplaum. Los ntawm cov txheej txheem ua phaj, cov duab kos duab thiab cov ntawv nyeem tau hloov mus rau hauv cov duab mesh, yog li ua tiav kev luam ntawv.
2, Qhov sib txawv ntawm cov phaj ua cov txheej txheem
Letterpress printing: Lub phaj ua txheej txheem ntawm cov ntawv luam ntawv feem ntau suav nrog cov kauj ruam xws li kev tsim duab kos duab, xaiv cov khoom siv phaj, kos duab kos duab lossis ntau lawm, thiab phaj tiav. Hauv kev luam ntawv nyem thaum ntxov, cov ntawv nyeem thiab cov duab feem ntau tau muab los ntawm tes rau ntawm daim hlau lossis hlau; Niaj hnub nimno nyem luam ntawv, ntawm qhov tod tes, ntiav cov khoos phis tawj-pab tsim thiab tsim cov txheej txheem los tsim cov ntawv luam ntawv siab los ntawm txoj kev xws li laser engraving lossis electroplating.
Kev tshuaj ntsuam luam ntawv: Lub phaj ua txheej txheem ntawm kev tshuaj ntsuam luam ntawv suav nrog cov kauj ruam xws li xaiv qhov screen, ncab, txheej nrog cov nplaum nplaum, raug, kev loj hlob, thiab ziab. Thaum lub sij hawm ua cov phaj, nws yog ib qho tsim nyog los tsim cov yeeb yaj kiab sib raug raws li cov duab kos duab thiab cov ntaub ntawv, thiab nthuav tawm nws mus rau ib qho screen coated nrog photosensitive nplaum, thiaj li hais tias cov photosensitive nplaum hardens thiab ua mesh qhov nyob rau hauv cov duab thiab cov ntawv nyeem, thaum khaws cov duab tsis zoo thiab cov ntawv nyeem nyob rau hauv lub xeev softened rau kev ntxuav thiab tshem tawm.
3, Kev sib piv ntawm cov ntawv luam tawm
Letterpress printing: Cov nyhuv luam ntawv ntawm cov ntawv luam ntawv feem ntau yog cov txheej txheem tuab tuab, xim puv, thiab muaj zog peb-seem. Vim lub protrusion ntawm cov duab thiab cov ntawv nyeem, tus number case tuaj yeem sau tag nrho ntawm lub substrate thaum lub sij hawm luam ntawv, ua kom pom qhov sib txawv ntawm cov xim txheej tuab, yog li txhim kho qhov pom ntawm cov khoom luam tawm. Tsis tas li ntawd, letterpress printing kuj muaj kev tiv thaiv zoo thiab ua haujlwm ntev, ua rau nws siv dav hauv qee qhov tshwj xeeb xws li txiaj, cov ntaub ntawv, thiab lwm yam.
Kev tshuaj ntsuam luam ntawv: Cov nyhuv luam ntawv ntawm kev tshuaj ntsuam luam ntawv yog qhov muag heev thiab muag muag. Vim tias tus number case tau xau mus rau lub substrate los ntawm lub qhov mesh, ib qho kev sib txuam ntawm tus number case txheej txheej tuaj yeem tsim, zam qhov teeb meem ntawm cov xim tsis sib xws uas yuav tshwm sim hauv kev luam ntawv nyem. Nyob rau tib lub sijhawm, kev tshuaj ntsuam luam ntawv kuj muaj cov yam ntxwv ntawm cov xim nplua nuj thiab cov khaubncaws sab nraud povtseg, uas tuaj yeem ua tau yooj yim rau kev luam ntawv ntawm cov qauv nyuaj xws li gradients thiab dots. Tsis tas li ntawd, kev tshuaj ntsuam luam ntawv kuj muaj qhov tshwj xeeb zoo hauv kev luam ntawv ntawm cov ntaub ntawv mos xws li ntaub, tawv, thiab lwm yam.
4, Kev sib piv ntawm cov khoom siv
Convex printing: Convex printing yog tsim rau kev luam ntawv ntawm ntau yam ntaub ntawv, xws li ntawv, yas, hlau, thiab lwm yam. Txawm li cas los xij, vim nws lub siab luam ntawv siab, muaj qee yam yuav tsum tau ua rau lub flatness thiab lub zog ntawm substrate. Tsis tas li ntawd, letterpress printing yuav ntsib tej yam nyuaj thaum luam ntawv mos los yog deformable cov ntaub ntawv.
Kev tshuaj ntsuam luam ntawv: Kev tshuaj ntsuam luam ntawv tuaj yeem siv rau yuav luag txhua hom ntaub ntawv, suav nrog ntawv, yas, hlau, ntaub, iav, ceramics, thiab lwm yam. txawm nyob rau qhov tsis sib xws los yog yooj yim deformed substrates.
5, Kev sib piv ntawm daim ntawv thov teb
Letterpress printing: letterpress printing muaj ntau yam kev siv hauv ntim luam ntawv, phau ntawv luam ntawv, ntawv luam ntawv, thiab lwm yam. Nws cov nyhuv luam ntawv tshwj xeeb thiab kev tiv thaiv kev ua txhaum cai ua rau nws nrov hauv cov ntim khoom siab, cov phau ntawv tawv tawv, cov ntawv tiv thaiv cuav, thiab lwm yam. Tsis tas li ntawd, hauv qee qhov tshwj xeeb xws li txiaj, cov ntaub ntawv, thiab lwm yam, letterpress printing kuj plays lub luag hauj lwm irreplaceable.
Screen printing: Screen luam ntawv tau nyiam ntau xim vim nws cov txheej txheem tshwj xeeb thiab daim ntawv thov dav. Hauv kev lag luam tshaj tawm, kev tshuaj ntsuam luam ntawv yog siv los tsim cov ntawv loj loj sab nraum zoov, tsheb lub cev ntawv nplaum, cov ntawv nplaum phab ntsa, thiab lwm yam; Hauv kev lag luam textile, cov ntaub ntawv luam tawm siv los ua ntau yam qauv thiab cov ntawv; Hauv kev lag luam hluav taws xob, nws yog siv rau kev txheeb xyuas thiab kho kom zoo nkauj ntawm cov khoom xws li Circuit Boards thiab cov khoom siv hluav taws xob. Tsis tas li ntawd, kev tshuaj ntsuam luam ntawv kuj tau ua kom pom nws qhov tshwj xeeb ntxim nyiam hauv thaj chaw xws li kos duab luam tawm thiab ua khoom plig tus kheej.
