Pantone Cigar Paper Boxes Qhov twg CTP phaj ua yog mus

 

Kaum xyoo dhau los, thaum lub sij hawm ntawm lub computer ncaj qha phaj ua pib nrog thermal technology, ntau cov tub txawg muaj lub tswv yim tias peb tau mus txog rau theem kawg ntawm txoj kev loj hlob ntawm offset printing daim hlau. Tab sis qhov no tsis yog li ntawd. Cov neeg siv txiav txim siab yam cuab yeej uas lawv xaiv yav tom ntej.

 

Txog rau 15 xyoo dhau los, txhua lub tshuab luam ntawv offset siv cov phaj ua zaj duab xis thiab tes ua. Rau 4- xim luam ntawv, cov txheej txheem no yuav tsum rov ua plaub zaug. Tom qab ntawd nws raug muab tso rau ntawm ib lub phaj offset nrog lub teeb ultraviolet ntawm lub tshuab luam ntawv, thiab tom qab ntawd yuav tsum tau tsim.

Los ntawm kev tsim lub tshuab loj 8-nplooj zaj duab xis raug, nws muaj peev xwm nthuav tawm cov nplooj ntawv digital ncaj qha rau ntawm 8-nplooj zaj duab xis. Koj tsuas yog tso ib daim ntawv loj ntawm zaj duab xis rau ntawm ib lub phaj thiab muab tso rau ntawm lub tshuab luam ntawv.

 

Cov kauj ruam mus rau CTP

Kev siv digital offset phaj exposure tshuab (CTP platemaking tshuab) tuaj yeem raug ncaj qha rau ntawm phaj. Yog li koj tuaj yeem txuag ntawm kev ua yeeb yaj kiab, tab sis koj yuav tsum ua siab ntev peb qhov hassles.

 

Thawj qhov yuav tsum yog daim ntawv pov thawj tag nrho cov ntawv pov thawj, uas yuav tsum tau luam tawm ntawm lub tshuab luam ntawv loj loj, txwv tsis pub muaj qhov yuam kev tuaj yeem pom ntawm lub phaj lossis xovxwm. Qhov thib ob uas koj yuav tsum tau ua yog yuav lub phaj raug lub tshuab, uas thaum xub thawj yog ntau kim dua li lub tshuab raug zaj duab xis. Qhov thib peb yuav tsum tau hloov dua siab tshiab rau digital offset printing, uas yog rhiab heev, yog li ntawd nyuaj rau lis, thiab ob zaug li kim li tsoos luam ntawv. Txawm li cas los xij, txij li lub tsev luam ntawv tau tshem tawm cov txheej txheem ua yeeb yaj kiab, uas txuag tau nyiaj ntau nrog rau lub sijhawm thiab tshem tawm qhov yuam kev, lub tsev luam ntawv tau lees txais qhov kev nce nqi no.

 

Tsis zoo thermal phaj

Lub rhiab heev ntawm cov phaj tsoos yog li 2000mj/cm2, thiab lub zog yuav tsum tau ntawm Agfa cov nyiaj phaj yog 0.35mj/cm2, uas yog 6,000 zaus sai dua li cov phaj ib txwm. Txawm li cas los xij, qhov rhiab heev txhais tau hais tias lub phaj kuj yog ib qho yooj yim rau kev ua haujlwm hauv kev tsim khoom, khaws cia thiab ua haujlwm, yog li nws tsis yooj yim rau kev cuam tshuam nrog tsis tsuas yog nyob rau hauv lub phaj manufacturing cog thiab kev thauj mus los, tab sis kuj nyob rau hauv kev cia, raug thiab kev loj hlob ntawm lub phaj. tshuab luam ntawv.

 

Qhov no tsis tuaj yeem hloov pauv thaum siv cov ntawv thermal luam ntawv, thiab nws cov spectral rhiab heev yog 830nm nyob rau hauv infrared band, yog li nws tuaj yeem ua tiav hauv lub teeb ci. Thaum Kodak tau tshaj tawm cov phaj no hauv xyoo 1996 hauv kev koom tes nrog Clio, nws zoo li cov thev naus laus zis thev naus laus zis yog CTP thev naus laus zis zoo tshaj plaws, txij li cov ntawv thermal cross-linked tsis zoo phaj tau pib siv. Hom phaj no yog preheated rau 110 degree C los ntawm laser nyob rau hauv cov ntawv luam. Tom qab lub phaj yog duab, nws yog rhuab nyob rau hauv lub qhov cub. Thaum txog 140 degree C, cov polymer hauv cov ntawv luam tawm yog thermally cross-linked rau hauv ib qho tshwj xeeb resistant resin. Tom qab qhov no thiaj li hu ua "preheating" txheej txheem, lub phaj yog tsim, tawm tsuas yog ib feem ntawm lub phaj uas tsim cov ntoo khaub lig-txuas txheej; Cov txheej txheem ntawm qhov tsis pom ntawm daim duab raug tshem tawm. Kodak lav kev luam tawm ntawm 500,000, qee cov neeg siv tuaj yeem tshaj 800,{11}}, thiab cov ntawv ci tuaj yeem ncav cuag ib lab luam tawm.

 

Txawm hais tias lub thermal tsis zoo phaj no muaj qhov rhiab heev ntawm 150mj / cm2, nws txoj kev ntseeg tau muaj zog heev, vim tias tsis muaj qhov cuam tshuam tsis zoo los yog tus tsim tawm kom muaj kev cuam tshuam rau cov phaj ua cov txiaj ntsig.

 

Zoo thermal phaj

Tag nrho cov tuam txhab phaj xav siv cov phaj thermal kom tau txais ib daim ntawm kev lag luam, yog li lawv tau tsim cov phaj zoo nrog 830nm wavelength imaging. Tag nrho cov tsis tau luam tawm qhov zoo ntawm cov phaj zoo yuav tsum tau yaj nrog lub laser beam kom tshem tawm cov txheej hauv tus tsim tawm. Yog li ntawd, yuav tsum muaj lub zog siab, lub phaj luam ntawv yuav tsum tau khaws cia ntawm qhov kub thiab txias ntawm lub Hoobkas rau ob peb hnub, thiab lub tshuab cua txias tau xa mus rau cov neeg siv khoom, thiab lub tshuab luam ntawv yuav tsum khaws cia ntawm qhov kub thiab txias kom deb li deb. raws li ua tau.

Tus naj npawb ntawm cov ntawv luam tawm ntawm cov phaj no nyob ntawm qhov kev tiv thaiv ntawm cov txheej txheem, yog li lub sij hawm tsim lub phaj yuav tsum tsis txhob ntev dhau. Txawm li cas los xij, yog tias lub sijhawm txhim kho luv dhau, lub phaj yuav pib qias neeg tom qab luam tawm ntau txhiab daim ntawv luam. Cov phaj no yog li rhiab heev rau cov txheej txheem kev hloov pauv ntau dua li photosensitive nyiaj phaj. Hom thermal phaj manufacturers tshaj tawm cov lus hais txawv txawv hais tias "tsis muaj preheating yog xav tau" vim hais tias cov tsev luam ntawv tsis kam siv lub hwj chim-tshuaj phaj cua sov rauv taws. Txawm li cas los xij, kev ua haujlwm ntawm kev ua kom muaj zog yog ua los ntawm cov chaw tsim khoom phaj, yog li ua kom lub siab ruaj khov yog qhov tseem ceeb, yog li qhov no tsis tau hais. Qhov rhiab heev ntawm cov pa hluav taws xob tsis zoo thiab qhov zoo yog 150-200mj / cm2, uas yog 10 mus rau 15 npaug siab dua qhov rhiab heev ntawm cov ntawv luam tawm ib txwm muaj. Niaj hnub no tag nrho cov phiaj xwm no tau hais txog 180% txog 200% siab dua li cov phiaj xwm ib txwm muaj.

 

Ntshav laser phaj

Vim tias lub tshuab sab hauv lub nruas raug tsis tuaj yeem ua rau thermal raug, Agfa muab cov ntsev ntsev ntawm nws cov khoom siv nrog cov ntshav laser diode nyob rau hauv kev ua lag luam rau Drupa 2000. Tom qab, Fujifilm thiab Kodak kuj tau tso cov ntshav laser luam ntawv daim hlau hauv khw. Cov phaj no tuaj yeem ua tiav nyob rau hauv lub teeb daj zoo nkauj, thiab zoo li cov nyiaj thiab cov ntawv polymer saum toj no, nws yog qhov nkag siab rau cov txheej txheem hloov.

 

Tsis muaj kev ua phaj

Ntawm Drupa 2004, Agfa tau qhia txog Azura (Green Star) kub yaj luam ntawv daim hlau, uas tsis siv tshuaj lom neeg txoj kev loj hlob, tab sis tsuas yog siv cov khoom siv txuas ntxiv mus tshem tawm cov yeeb yaj kiab, ntxuav thiab kua nplaum. Yog li ntawd, qhov zoo ntawm thermal raug yog li ruaj khov uas qhov kev nyab xeeb ntawm kev ua yog siab npaum li qhov tsis zoo thermal version. Tab sis cov ntawv kho mob tsis pub dawb yog 10 feem pua ​​​​ntau dua li cov phaj thermal, thiab cov tshuab luam ntawv lees txais tus nqi vim tias lawv txuag nyiaj rau tus tsim tawm, saib xyuas, thiab cov nqi tshuab. Txij li thaum xyoo 2006IPEX luam ntawv qhia, Kodak thiab Fujifilm kuj tau muab cov txheej txheem tsis pub dawb, uas yog thermally imaged thiab tsuas yog tshem tawm thaum luam tawm ntawm cov xovxwm.

 

Ib txwm luam ntawv phaj

Nws zoo nkaus li tias niaj hnub no cov tshuab luam ntawv tsuas muaj kev xaiv ntawm thermal, ntshav laser thiab cov txheej txheem luam ntawv tsis pub dawb. Tab sis qhov kev xav ntawd tau yuam kev: nyob rau xyoo 1990s, Bess Printing tau tsim lub tshuab raug hu ua UV-Setter rau kev luam ntawv offset. Tam sim no ntau dua 800 ntawm cov tshuab no tau muag thoob ntiaj teb, thiab cov ntaub ntawv muag khoom tseem tab tom nce sai. Yog vim li cas yog tias lub tshuab kis tau tus mob no tau zoo heev rau ntau xyoo, thiab lub tuam txhab tau ua haujlwm tsis tu ncua los txo lub sij hawm raug.

 

Tab sis qhov laj thawj tseem ceeb yog tias cov tsev luam ntawv tsuas yog xav txo tus nqi ntawm cov ntawv luam tawm thaum lawv nce lub CTP Express. Nyob rau tib lub sijhawm, lub tshuab luam ntawv tswj xyuas qhov kev ua haujlwm siab dua ntawm qhov tsis txaus ntseeg offset luam ntawv phaj zoo li ua ntej.

 

Yog tias lub tsev luam ntawv twb tau siv CTP thiab them tus nqi phaj siab dua, nws tuaj yeem hloov mus yuav UV-setters thaum nqis peev hauv lwm txoj hauv kev, yog li nws cov nqi phaj tuaj yeem yuav luag ib nrab yav tom ntej. Yog tias lub tshuab luam ntawv siv 20,000 square metres ntawm daim phiaj ib xyoos, suav ntawm 8 euros ib square meter, tus nqi luam ntawv txhua xyoo yog 160,000 euros, nws tuaj yeem txuag tau 80,{{ 7 } € !

 

Lub phaj yog rhiab heev rau lub teeb violet

Bessin siv UV teeb rau qhov raug thiab siv cov txheej txheem patented uas tsis muaj leej twg tuaj yeem ua tau txog tam sim no. Txij li thaum lub IPEX2006 luam ntawv exhibition, Bessin tau muaj nws thawj comrade - Luscher Company, nyob rau hauv lub Plaub Hlis 2006, lub tuam txhab launched ib tug thermal version ntawm lub exposure tshuab nrog ntshav laser diode, uas siv ntshav laser diode es tsis txhob thermal laser diode. Txij li thaum Lub Ib Hlis 2007, thawj Xpose-UV-Conventional exposure tshuab tau siv nyob rau hauv lub teb chaws Yelemees. Thawj pawg ntawm 20 lub tshuab raug muag tau xa tuaj rau lub Plaub Hlis 2007.

 

Tus nqi tam sim no ntawm lub tshuab raug hluav taws xob no yog kwv yees li 25% siab dua lub tshuab hluav taws xob, vim tias tam sim no diode nrog 140mj / cm2 tso zis hluav taws xob yog kim heev. Txawm li cas los xij, raws li tus nqi phaj raug txo los ntawm ib nrab, tus nqi siab dua tau them rov qab rau lub xyoo ua haujlwm thib ob thiab tus nqi qis dua ntawm cov phaj tom ntej tau qhia tag nrho hauv cov tuam txhab nyiaj.

 

Plate manufacturers cov tshuaj tiv thaiv

Nws yeej ib txwm yog cov ntaub ntawv uas thaum lub tshuab tshiab tuaj nrog, tib tus neeg muag khoom tsuas tuaj yeem muab ib lossis ntau ntawm ob daim hlau, thiab nws yuav siv sijhawm li ob xyoos lossis ntau dua kom txog rau thaum lwm cov tuam txhab phaj tuaj yeem muab cov phaj no. Thaum lub violet laser diode yog siv los nthuav tawm ntawm cov tsoos phaj (PS phaj), qhov teeb meem no txawv kiag li, vim hais tias tag nrho cov phaj manufacturers pom kom meej meej lub lag luam tshiab thiab muab cov phaj zoo sib xws rau qhov no digital UV raug. Muaj txog 20 lub phaj zeb muab ntau tshaj 60 hom phaj. Nws tsis yog qhov xav tsis thoob tias txhua lub phaj mills txaus siab ua haujlwm nrog ob lub tuam txhab raug tsim tawm, Besprint thiab Luscher, txhawm rau muab cov ntaub ntawv phaj rau lawv cov neeg siv khoom.

 

Cov tshuaj tiv thaiv ntawm lub tsev luam ntawv

Txawm hais tias qhov kev thov tshiab rau kev luam ntawv offset yuav ua rau tus nqi ntawm lub phaj luam ntawv no poob qis, cov lus teb tsis yog. Vim tias cov phaj loj loj ua lag luam tsis tu ncua hais tias tsis muaj nyiaj yuav tsum tau ua los ntawm kev luam ntawv offset. Txhua tus neeg uas ib txwm xav txog kev ua cov kauj ruam ntawm kev ua daim hlau ntawm cov paib qub nrog lub tshuab tshiab cov phaj kis tau tus mob tam sim no muaj qhov thib ob lub tshuab xa tawm los xaiv. Tej zaum yuav muaj ntau tus neeg xa khoom sai sai.

 

Yog li vim li cas Agfa, Fujifilm thiab Kodak tso tseg txoj kev lag luam? Vim tias lawv tsim daim hlau, lawv puas txhawj xeeb tias cov phiaj no yuav tsis muag thaum lawv txais cov tshuab raug tshiab?
