1. Daim ntawv pub noj
Daim ntawv no yog qhov chaw kom paub meej tias daim duab yog nyob rau hauv ib qho chaw nyob rau sab sau toj siab txhua zaus nws luam tawm. Qhov no yuav tsum muaj rau xim printing thiab monochrome printing. Rau cov xim luam tawm tau tham ntawm no, cov xim ntawm cov ntawv feem ntau yog plaub xim ntawm cyan, magenta, daj, dub, los yog ntau dua. Rau txhua lub xim luam ntawv, tus cwj pwm uas yuav tsum tau muab xa mus rau ib qhov chaw ntawm lub substrate los ntawm lub tshuab luam ntawv, uas ua kom ntseeg tau tias cov phom sij ntawm cov xim zoo yog raug overlapped ua ke kom tiav meej tshaj qhov qub, yog li mus rau qhov tseeb ntawm me nyuam yaus cov xim nplua nuj. Yog li ntawd, lub luag hauj lwm ntawm cov ntawv muab ntaus ntawv ntawm cov ntawv xovxwm tseem ceeb heev. Feem ntau, qhov chaw nyob ntev yog hu ua txoj cai nyob hauv ntej (raug xa mus rau hauv pem hauv ntej koob qhia), thiab qhov chaw ua haujlwm tom qab yog hu ua txoj cai tswjfwm sab (raug xa mus rau sab nrig). Qhov kev ua tau zoo, qhov muaj nqis thiab kev hloov ntawm qhov kev ntaus ntawv tsis yog tsuas yog muaj kev txiav txim siab rau qhov zoo ntawm cov khoom luam tawm, tab sis kuj muaj kev sib raug zoo nrog rau theem ntawm kev tsim khoom tsim.
Txhawm rau pab soj ntsuam xyuas qhov tseeb tshaj ntawm kev luam, ob txoj kab hauv hla kev loj tshaj plaws yog luam tawm ntawm tib qho chaw nyob nruab nrab ntawm sab laug thiab sab sab ntawm nplooj ntawv. Thaum luam tawm, qhov khuam thiab kev kho ntawm kev tshaj tawm ntawm lub qhov rooj thiab lub yaw lub voj voog raug kuaj xyuas thiab kho. Nyob rau hauv rooj plaub, daim ntawv sau ntawm cov duab kos tau muab pov tseg.
2. Nthuav kev ntaus thiab luam ntawv siab
Lub plhaub lub taub hau ntawm qhov offset printing xovxwm yog ib lub tshuab luam ntawv, uas yog hu ua ib qho kev ntaus ntawv. Nws cov qauv kev ua tau zoo thiab kev tsim kev ncaj ncees yog ncaj qha ntsig txog qhov zoo ntawm cov teeb meem luam tawm thiab kev ua haujlwm ntawm kev tsim. Tib lub sij hawm, nws yog qhov kev ntsuas rau kev hloov ntawm tag nrho cov cheebtsam. Txawm hais tias tsis muaj qhov offset xovxwm, chav tsev stamping ua raws li txoj cai hauv peb lub hauv paus: Nws tsuas yog muaj cov phom lub tog raj, ib daim pam poom thiab lub tswv yim kheej. Lub ntsiab haujlwm ntawm cov phom khawm yog:
1 Ntsaws lub phaj thiab kho qhov chaw ntawm lub phaj.
2 Qhov ntev ntawm cov ntawv luam yuav raug hloov.
3 Hloov kev sib cuag ntawm cov phom lub tog raj kheej thiab pam lub tog raj kheej. Daim pam poom (pam lub tog raj kheej) muab qhwv nrog ib daim tawv, khoob khoob khawm rau sab nraud ntawm lub tog raj kheej kom hloov cov ntawv ntawm lub phaj. Lub luag haujlwm ntawm daim pam kheej lub khawm yog:
1 hloov number case;
2 kom paub txog qhov yuam kev ntawm lub tshuab;
3 tsis hnov qab.
Lub tswv yim kheej kheej yog qhov tseem ceeb tshaj plaws hauv lub tshuab tua hluav taws. Nws nto tau siab ua precision, acid thiab alkali tsis kam thiab corrosion kuj. Lub simplified lub cev kuj muaj kev yeem thiab muaj zog. Nws tuaj yeem tiv thaiv kev poob siab thiab kev vibration. Nws yog nruab nrog txoj kev ywj pheej. Lub ntsiab ntawm lub tswv yim tseem ceeb yog:
1 Txhawb nqa ntawv thiab luam ntawv tiav;
2 hloov ntawv;
3 Nyob rau hauv niaj hnub offset presses, lub tswv yim kheej kheej yog lub hauv paus rau kev hloov ntawm kev sib raug zoo ntawm lwm qhov chaw.
Nws yuav tsum tau qhia tshwj xeeb tshaj tawm tias cov luam ntawv siab yog muab los ntawm lub zog ywj pheej tsim los ntawm kev sib deev ntawm daim ntawv cog lus ntawm daim pam ntawm daim pam lub tog raj kheej. Plate thooj voos kheej kheej thiab tswvyim thooj voos kheej kheej yog cov tawv tawv uas tsis yooj yim deformed tom qab daim ntawv thov siab. Yog li ntawd, thaum lub sij hawm luam ntawv, daim pam pob lub thawv ntim thiab lwm ob lub thawv tsis nyob hauv txoj kab ncaj nraim, tab sis ib tus nplhaib nrog qhov dav. Qhov siab tshaj plaws tus nqi deformation nqi ntawm daim pam feem ntau yog hu ua luam siab nyob rau hauv ntau lawm. Qhov tseeb, qhov siab tshaj plaws (tus nqi deformation) yog qhov sib npaug ntawm ob kab thooj voos kheej kheej ntxiv rau qhov sib txawv ntawm lub thickness ntawm daim ntawv, lub ntxaum, thiab qhov chaw nruab nrab ntawm ob lub thawv.
Thaum lub sij hawm thaum tus number case hu rau hauv daim ntawv, nyob rau hauv tej qhov siab ntawm lub thawv, lub khi molecules yog forcibly pressed rau hauv fiber ntau kis ntawm daim ntawv, thiab ces qhov sib txawv capillary phenomenon hauv daim ntawv txheej yog maj mam thiab dawb do permeated. Yog li, lub siab yog ib qho tseem ceeb rau cov phom yuav qhuav thiab permeable ntawm daim ntawv deg. Thaum lub tshuab luam ntawv siab tshaj qhov nqi qis, lub luam tawm ntawm lub tshuab luam ntawv yuav pib kis mus rau qhov tsis pub tshaj ntawm cov ntawv luam tawm, thiab tus lej number case hloov pib. Cov ntawv luam tawm print yog cov loj heev, thiab daim duab yog obviously distorted. Yog li ntawd, luam tawm ntau tshaj ib qho txiaj ntsim zoo tsis tsim nyog rau luam ntawv.
Qhov ob, cov txheej txheem tsis yog ntawm qhov kev luam ntawv luam tawm
Kev luam ntawv tsis feem ntau siv rau hauv kev luam ntawv yog: ink hue, number case hue, number case drying, paper thickness, paper smoothness, ntawv ntim ntawv, daim ntawv txheeb ze cov ntawv nyeem, daim ntawv deg zog, ntawv p H, , pam tuab, pam tuab, lub thauv ntim, lub thauv ntim, lub thauv ntim, lub thauv ntim, lub thauv ntim ntawm lub thawv ntim, hnav thiab hais txog.
Hauv qhov tseeb cov ntawv luam tawm kev lag luam, nws tsis tsim nyog lossis tsis los kho thiab tswj tag nrho cov saum toj no. Qhov tsis zoo xws li dampening kua, daim pam, cov quav hauv plawv, dej rau menyuam thiab hauv ob sab yog feem ntau tsis hloov kho thiab hloov thaum lub txheej txheem ntau lawm, thiab yuav siv tau ua ib qho system. Ua ntej teeb meem. Los ntawm cov seem ntawm kev tswj kom muaj kev tswj, qhov tsis ntawm kev tswj kev haum rau qhov offset luam ntawv uas yog xws li number case control, luam tsis, proofing, proofs, daim hlau, number case thiab ink number case, ink pattern sample files, layouts, substrates, thiab paper kev pub noj. Tos.
Duav Kev Tswj: Tuaj hu ua Xim Tswj (Colorant C ontrol), vim siv cov xim uas tsis muaj cov cwj pwm txawv ntau dua, tswj kev ua cov txheej txheem PS nrog colorants, nws muaj cov cwj pwm los yog cov kauj ruam uas piav qhia txog qhov kos hauv PS nplooj ntawv. Cov ntaub ntawv xim yog hloov mus rau cov ntsiab lus ntawm cov cuab yeej colorant nplooj ntawv, xws li ntaus cim qhov chaw xim, luam cov xim sib lawv liag, thiab cov zoo li.
Tsis pub luam tawm: Txheeb xyuas cov chav nyob lossis tus cwj pwm uas yuav tsum tau siv rau cov txheej txheem luam ntawv, xws li kev ncaj nraim, kev siv ziab khaub ncaws, luam yeeb xim, , xim pawg neeg daim ntawv teev npe, ob npaug ntawm cov ntawv luam xim xim pawg siv kev txiav txim, hom ntawv hom, qhov chaw qhwv ntsej muag, qhov siab tshaj ntawm kev luam ntawv ntawm lub tshuab luam ntawv, daim ntawv xa txuj ci, qhov ci ci, thiab cov zoo li.
Cov Ntawv Pov Thawj Tuav Ntaub Ntawv: Cov ntaub ntawv pov thawj muab los ntawm lub Department of Preparatory yog lub hauv paus rau kev tswj cov txheej txheem luam ntawv. Yuav tsum muaj qhov teeb meem ntawm lub voos pov thawj. Xam Xaj: Cov qauv ntawm kev luam tawm dhau los yog siv rau qhov kev luam ntawv tam sim no.
Phaj: Feem ntau ntawm cov ntawv siv hauv niaj hnub offset luam tawm yog cov PS versions. Cov PS version yog raws li cov duab ntawm cov duab hluav taws xob (polymer layerensitive) ua ib daim duab nraaj, thiab cov ntawv phaj duab yog me ntsis siab tshaj qhov seem. Feem xyaw hydrophilic yog ib qho yeeb yaj duab ntawm txhuas oxide. Waterless offset luam ntawv siv ib hom ntawv uas muaj menyuam ua ntej luam tawm cov ntawv luam tawm. Qhov seem ntawm yog ib qho silica gel uas rov qab ua piv txwv. Cov duab seem yog ib txheej ntawm ib nyuag concave polymer, thiab cov nplaim ntawm lub phaj yog resistant rau oxidation. Qhov zoo ntawm PS version ncaj qha cuam tshuam qhov zoo ntawm cov luam.
Lej: Cov yam ntxwv xim ntawm peb lub ntsiab xim ntawm tus number case ncaj qha rau qhov txawv ntawm cov xim tiag tiag ntawm cov ntawv luam tawm. Sib txawv ntawm peb hom xim inks muaj ntau xim xim, grey nplua thiab efficiency, yog li cov xim ntawm tus number case yog txawv. Vim li no, thaum luam cov khoom zoo, yuav tsum siv tib hom xim muaj suab npe ntawm tib lub khw. Ntxiv mus, thaum lub sij hawm luam ntawv, sim tsis ntxiv cov neeg pab txhawb ntau rau tus thawj tus cwj mem los ua tus number case emulsification los yog saturation txo. Thaum hloov xim, yog tias cov xim tom ntej tsis yog ntxuav, xim hloov ntawm cov xim tom kawg yuav nce, thiab qhov txhuab theem yuav nce, yog li cuam tshuam cov xim luam tawm ntawm cov ntawv luam tawm. Naj zauv tsam cov lus qhia: Txheeb tus cim ntaus cim tsis rau lub tshuab luam ntawv, tsis hais txog cov lus qhia, nrog rau tus lej feem ntau ntawm lub tshuab luam ntawv nyob hauv daim ntawv qhia txog kev noj mov, thiab tus lej number case uas yuav tsum tau muaj nyob rau ntawm kab rov tav ntawm lub cheeb tsam (specifying tus nqi ntawm tus number case rau txhua cheeb tsam number case), qhov nqi yog ntawm 0 thiab 1, thiab 1 yog 1 0 0%).
Layout: Hais txog kev teeb tsa kev teeb tsa rau kev teeb tsa kev tsim qauv, nrog rau kev npaj lub npe, seb puas yuav tau ua qhov tsim qhov teeb meem, qhov ntau kawg ntawm cov ntaub ntawv uas tau hais tseg thaum ua tiav, qhov ntau npaum li cas ntawm cov ntaub ntawv siv, seb puas tau ntxiv cov ntawv ntxiv, yuav ua li cas kos npe thiab teeb duab cov khoom nta, thiab lwm yam. Ntawm lawv, chav teeb layout nrog rau txoj kev txiav, cov ntsiab lus ntawm nplooj ntawv, qhov ntshav ntu, seb lub sab tau raug daig, thiab cov zoo li.
Cov ntawv luam tawm: Cov ntawv luam tawm yog lub hauv paus rau cov xim ci ntawm cov ntawv luam tawm. Yog hais tias tus dawb ntawm lub substrate yog high, lub ci ci ntawm cov xim yuav kho. Conversely, lub grey substrate zoo li muab ib qho nyiaj me me rau txhua qhov xim ntawm tus cwj pwm, uas qhia tus npub xim. Tsis tas li ntawd, tus nqi ntawm substrate absorbency yuav cuam tshuam rau kev tuaj yeem ntawm cov xim. Rau ib qho yooj yim muaj zog substrate, qhov kev ua luam tsis tsim ib qho puv xaj puv ntim quav rau saum npoo, thiab lub khob cij excessively penetrates mus rau hauv lub substrate kom qhuav lub blot. Ib daim ntawv uas muaj lub qhov capillary loj ua rau ib co pigment txeem rau hauv daim ntawv nrog tus phias, uas yog txo cov xim xim thiab rau qhov vividness ntawm cov xim.
