Tom qab 40 xyoo ntawm txoj kev loj hlob, Tuam Tshoj tau dhau los ua lub ntiaj teb cov neeg tsim khoom loj tshaj plaws thiab cov neeg siv khoom hauv kev lag luam daim ntawv lo. Kev noj txhua xyoo ntawm daim ntawv lo yog kwv yees li 16 billion square metres, kwv yees li ib feem peb ntawm tag nrho cov ntawv sau thoob ntiaj teb. Ntawm lawv, kev noj cov ntawv nplaum rau tus kheej muaj ntau tshaj li ib feem peb ntawm tag nrho cov khoom siv ntawm cov ntawv nyob hauv Suav teb, uas yog 6 billion txog 7 billion square metres, thiab cov seem yog cov ntawv sau, cov ntawv ntim zaj duab xis, hauv cov ntawv pwm. thiab lub tes tsho labels
Suav daim ntawv lo luam ntawv, tshwj xeeb tshaj yog tus kheej-adhesive label printing, yog heev cuam tshuam los ntawm Nyiv. Tam sim no, letterpress luam ntawv nyiaj txog li 60%, tseem yog lub hauv paus ntawm kev lag luam luam ntawv; Offset luam ntawv nyiaj txog li 20% thiab yog txoj kev loj hlob sai tshaj plaws; Flexography luam ntawv tso nyiaj txog li 10%, yog qhov zoo tshaj plaws ntawm kev luam ntawv, tab sis cuam tshuam los ntawm ntau yam hauv Suav teb, tam sim no tau teeb tsa hauv ntau qhov ntau, khau raj me me. Lwm 10% yog digital printing thiab lwm yam kev luam ntawv xws li tshuaj ntsuam luam ntawv, gravure printing thiab tshwj xeeb printing
Cov luam ntawv digital yog qhov kev txhim kho sai tshaj plaws hauv kev luam ntawv daim ntawv lo. Feem ntau, cov luam ntawv digital siv inkjet, toner, hluav taws xob number case thiab inkjet hloov txoj kev.
Qhov zoo tshaj plaws yog kev luam ntawv sib xyaw, uas ua ke nrog cov luam ntawv digital nrog cov luam ntawv ib txwm muaj.
Xya-xim luam ntawv, tseem hu ua "high-fidelity printing", nthuav cov xim gamut thiab zoo heev txhim kho xim zoo ntawm cov ntaub ntawv luam tawm. Siv dot overlay printing teb es tsis txhob tshwj xeeb xim number case printing teb, tsis tas yuav configure tshwj xeeb xim number case, txo cov khoom noj thiab nqi; Thaum lub tshuab luam ntawv luam tawm ntau qhov kev txiav txim, nws tsuas yog yuav tsum tau hloov lub phaj yam tsis tau ntxuav lub cots thiab hloov tus cwj mem, uas txhim kho kev tsim khoom.
3. Waterless offset luam ntawv
Nws siv tus cwj mem hloov qis, siv rau hauv cov khoom siv rau cov menyuam cov cwj mem hloov, tus cwj mem viscosity thiab xim xim sib txawv tuaj yeem hloov kho, luam xim zoo ib yam, kev luam ntawv siab, yog 2 ~ 3 zaug ntawm cov khoom siv luam ntawv ib txwm siv.
Flexography yog ib hom kev luam ntawv uas siv flexo daim hlau thiab hloov cov number case los ntawm cov menyuam anilox. Flexographic luam ntawv phaj feem ntau siv lub thickness ntawm 1-5mm photosensitive resin phaj. Ink muab faib ua peb pawg, raws li dej-raws li number case, cawv-soluble number case, UV number case. Raws liflexographic luam ntawv number case yog ntsuab, nws tau siv dav hauv kev ntim khoom noj khoom haus luam ntawv thiab muaj kev cia siab dav.
PS phaj luam ntawv tus kheej-nplaum daim ntawv lo yog nrog tus nqi qis ntawm offset phaj ua thiab cov nyhuv luam ntawv zoo, offset label tshuab yog thawj qhov kev xaiv ntawm daim ntawv lo luam ntawv lag luam ntxiv rau cov tshuab luam ntawv ib txwm siv. Offset printing ua rau qhov tsis xws luag ntawm letterpress graphics, phaj ua tus nqi qis, haum rau txhua yam kev txiav txim, txais tos los ntawm cov tuam txhab luam ntawv.
Cov yam ntxwv loj tshaj plaws ntawm letterpress yog luv, tiaj tus, nrawm, luam ntawv lag luam tuaj yeem ua rau lawv tus kheej phaj, luam ntawv number case, zoo txee, ua haujlwm yooj yim, yooj yim kho, haum rau txhua yam khoom nruab nrab daim ntawv lo.
Letterpress tshuab feem ntau yog muab faib ua ob pawg: ib qho yog ib nrab ntawm cov ntawv sau tshuab, feem ntau hu ua letterpress intermittent tshuab; Lwm qhov yog tag nrho cov ntawv sau teb. Txawm hais tias letterpress daim ntawv lo luam ntawv tsis tau pom nyob rau hauv cov ntawv sau saum toj kawg nkaus luam ntawv lag luam hauv Suav teb, Nws tseem yog lub zog tseem ceeb ntawm tus kheej-nplaum daim ntawv luam ntawv hauv cov lag luam me thiab nruab nrab, suav txog li 60%, thiab qhov xwm txheej no yuav tsis hloov. nyob rau hauv lub sij hawm luv luv.
Kev sib xyaw luam ntawv yog ua tiav ntau txoj kev luam ntawv sib txawv ntawm ib lub cuab yeej, uas feem ntau ua tiav ntawm flexography tshuab luam ntawv,
Kev sib xyaw ua ke luam ntawv feem ntau yog ua los ntawm flexography luam ntawv ua ke, yog tias tsim nyog, ntxiv txias stamping, tshuaj ntsuam luam ntawv, ib kauj ruam los ua kom tiav cov luam ntawv. Combined printing nyob rau hauv lub niaj hnub kev txiav txim siab yog kev sib xyaw ntawm cov luam ntawv nrog cov tsoos luam ntawv, uas yog, ib daim ntawv lo muaj ob qho tib si luam ntawv thiab cov luam ntawv digital nrog cov ntsiab lus sib txawv, tsim cov ntaub ntawv sib txawv ntawm cov ntaub ntawv luam tawm ntau lawm.
Txoj kev loj hlob ntawm kev siv tshuab luam ntawv yog digitalization, thiab digitalization pib los ntawm kev nias ua ntej. Kev lag luam daim ntawv lo tau pib paub CTP phaj ua hauv flexography thiab offset luam ntawv, tab sis qhov nkag mus ntawm CTP phaj ua hauv letterpress tsuas yog kwv yees li 10%, thiab Tuam Tshoj txoj kev lag luam daim ntawv lo yog cov ntawv xov xwm, yog li CTP phaj ua lag luam muaj peev xwm loj hauv kev lag luam. daim ntawv lo kev lag luam.
9. Nyob rau hauv-pwm daim ntawv lo khoom
Nyob rau hauv-pwm daim ntawv lo yog ib qho ntawm cov khoom tsim sai tshaj plaws nyob rau hauv daim ntawv lo kev lag luam saw hauv tsev thiab txawv teb chaws. Nws muaj keeb kwm ze li 30 xyoo hauv Suav teb. Nws muaj ob yam ntxwv: ua ntej, nws muaj cov nyhuv zoo nkauj thiab yog cov caviar rau cov dav dav hauv tsev neeg daim ntawv lo; Qhov thib ob, vim tias tsis muaj cov ntawv hauv paus, tsuas yog ib txheej ntawm zaj duab xis, daim ntawv lo tuaj yeem rov ua dua nrog lub thawv, yog li cov yam ntxwv tiv thaiv ib puag ncig zoo. Nyob rau hauv-pwm daim ntawv lo kuj yog ib txoj kev kho kom zoo nkauj pom zoo los ntawm thoob ntiaj teb ntim thiab luam ntawv kev lag luam. Nws tau muab faib ua ob pawg: tshuab moulding thiab txhaj tshuaj molding.
