Yuav ua li cas cov ntawv luam tawm digital tuaj yeem cuam tshuam los ntawm cov txheej txheem fwj
Niaj hnub no, nrog rau kev loj hlob ntawm kev thov rau tus kheej customization thiab luv luv -khiav luam ntawv, digital printing yog loj hlob sai heev, nrog rau kev siv technology lossi txhim kho. Kev kub ceev, kev ua haujlwm siab, thiab kev ua haujlwm siab tau maj mam dhau los ua 'Golden hom' ntawm cov luam ntawv digital, tsav tsheb cov tuam txhab luam ntawv los tuav cov kev hloov pauv thiab kev hloov kho ntse.
Nyob rau hauv qhov kev hloov pauv no tau tshwm sim los ntawm kev luam ntawv digital, ntau thiab ntau lub tuam txhab luam ntawv luam tawm tau nquag teb rau kev hloov pauv hauv kev lag luam, kho lawv cov tswv yim, thiab nqis peev ntau hauv cov cuab yeej luam ntawv digital thiab thev naus laus zis. Lawv tab tom txhim kho cov txheej txheem ntau lawm thiab txhim kho cov kev pabcuam zoo, txhawm rau kom tau txais kev tuav pov hwm hauv kev lag luam muaj kev sib tw. Lub hom phiaj yog hloov pauv los ntawm kev luam ntawv ib txwm siv rau digital thiab ntse luam ntawv, ua kom tau raws li cov neeg siv khoom sib txawv thiab tus kheej daim ntawv lo luam ntawv xav tau.
Txawm li cas los xij, cov teb tshiab inevitably tuaj nrog cov kev cov nyom tshiab. Cov tuam txhab luam ntawv luam ntawv tseem ntsib ntau yam teeb meem hauv kev tsim cov luam ntawv digital. Thawj thiab foremost yog qhov teeb meem nqi. Txawm hais tias nws yog tus nqi ntawm cov khoom siv, tus cwj mem, luam ntawv lub taub hau, lossis daim ntawv thov software, cov nuj nqis no zoo li lub roob sawv hauv txoj kev ntawm lub tuam txhab kev txhim kho digital luam ntawv, ua rau nws txaus ntshai mus rau tom ntej.
Thib ob, ntawm cov thev naus laus zis thev naus laus zis, txawm tias cov txiaj ntsig ntawm digital luam tawm tuaj yeem ua raws li tus qauv zoo ntawm cov ntawv luam tawm ib txwm ua rau ntau lub tuam txhab luam ntawv tsis txaus siab thaum xaiv cov cuab yeej luam ntawv digital. Kev luam ntawv ib txwm tau dhau mus ntev - lub sij hawm kev loj hlob thiab kev siv thev naus laus zis, tsim cov txheej txheem kev paub tab nrog cov qauv siab hauv cov xim luam tawm, nthuav dav kev ua tau zoo, thiab tag nrho cov txiaj ntsig. Hauv kev sib piv, cov luam ntawv digital, txawm tias nrawm, hloov tau, thiab tus kheej, tseem muaj qhov sib txawv hauv kev sib piv lossis ncav cuag cov qauv ntawm kev luam ntawv ib txwm muaj. Los ntawm qhov no, nws yog qhov tseeb hais tias qhov kev thov rau seamless kev koom ua ke ntawm digital thiab tsoos luam ntawv tau dhau los ua lag luam xav tau sai rau kev lag luam luam ntawv.
Qhov tseeb, kev luam ntawv digital tuaj yeem ua tiav qib siab - luam ntawv zoo uas phim cov luam ntawv ib txwm muaj nrog qee qhov kev hloov kho. Piv txwv li, hauv daim duab hauv qab no, sab laug qhia txog PS phaj luam tawm, thiab sab xis qhia tau hais tias tus cwj mem hluav taws xob, thiab cov ntawv luam tawm twb ze heev.
Offset luam ntawv dot
Electronic Ink Halftones
Qhov no yog vim tias offset luam ntawv ua haujlwm ntawm lub hauv paus ntsiab lus ntawm dej - number case tshuav nyiaj li cas, ua rau ib nrab ntawm cov xim saturation, emulsification nyob ib ncig ntawm thiab nyob rau saum npoo ntawm cov dots, thiab tsawg ntom. Hauv qhov sib piv, tus cwj mem hluav taws xob tso siab rau cov qauv hauv electrostatic, muab ib nrab ntawm cov xim saturation ntau dua, ntau dua thiab tsawg deformed dots, thiab ntau dua. Yog tias ob leeg siv 150 lpi npo zaus, tag nrho cov number case ntim (xim xim) ntawm cov tshuab luam ntawv hluav taws xob yog qhov siab dua li ntawm PS phaj offset prints. Yog li ntawd, ua kom cov tshuaj ntsuam zaus hauv hluav taws xob luam ntawv tuaj yeem txo cov number case ntim, txo cov xim ntom, thiab ua tiav cov xim txuam nrog PS phaj offset luam ntawv.
Yog li, dab tsi lwm txoj hauv kev tuaj yeem ua rau cov ntawv luam tawm mus txog qhov zoo ntawm kev luam ntawv? Yuav ua li cas cov tuam txhab luam ntawv luam ntawv siv cov luam ntawv digital kom ua tiav cov khoom tsim tau zoo tshaj plaws? Yuav ua li cas cov kauj ruam yuav tsum tau hloov cov luam ntawv ib txwm siv rau digital printing?
