Laser Imagesetter Performance Parameters
Feb 14, 2022
Cov kev ua haujlwm tseem ceeb ntawm lub laser imagesetter yog: cov ntaub ntawv raug (cov ntaub ntawv daws teeb meem), rov ua dua (sau npe yuam kev), hom ntawv, ceev ceev thiab laser wavelength, thiab lwm yam. tus duabsetter. Qhov ntsuas kuj yog tus qauv rau kev faib cov qib ntawm cov duabsetters.
Cov ntaub ntawv raug
Laser Imagesetter
Cov ntaub ntawv raug yog hais txog tus naj npawb ntawm cov teeb pom kev zoo uas tus duab duab tuaj yeem sau rau ib chav tsev ntev, uas yog, qhov kev daws teeb meem kaw, feem ntau qhia hauv dots ib nti (dpi) lossis dots ib centimeter (dpc). Qhov siab dua qhov kev daws teeb meem, qhov me me ntawm qhov chaw laser thiab qhov ntau dua qhov ntom ntawm qhov chaw. Vim tias cov dots ntawm cov duab luam tawm yog tsim los ntawm ntau cov kab teeb laser, qhov me me ntawm lub laser qhov chaw, ntau cov dots uas ua rau cov dots nyob rau hauv tib lub xov tooj ntawm cov kab screen, thiab qhov kev hloov pauv ntau dua hauv qib grey ntawm cov duab uas tuaj yeem ua tau. tsim, los yog , ua kom cov dot loj me me nyob rau hauv cov xwm txheej ntawm kev ua kom muaj cov qib grey, uas yog, kom tau txais ntau dua ntawm cov kab tshuaj ntsuam. Nyob rau hauv qhov ntau ntawm lub tshuab luam ntawv, txhua lub sij hawm qhov pom ntawm lub laser dot yog nce los yog tsawg, qhov luaj li cas ntawm luam ntawv dot hloov los ntawm ib theem, uas yog ib tug grey theem ntawm txawv ntxoov. Yog li ntawd, ntau qhov chaw laser uas ua rau lub dot, ntau qib grayscale raug tsim. Nyob rau hauv txoj kev no, lub koob yees duab tuaj yeem tsim tau txog 256 qib grey, uas yog, luam ntawv teev yog tsim los ntawm 16 × 16 laser dots.
Rov ua dua
Rov ua qhov tseeb yog hais txog qhov tseeb ntawm cov duab txoj hauj lwm ntawm txhua lub phaj xim, uas yuav tsum tau rau xim luam ntawv, thiab feem ntau yog xam los ntawm kev sib tshooj ntawm thawj xim phaj thiab lub phaj xim kawg. Monochrome prints tsis xav tau overprinting, yog li qhov tseeb ntawm kev sau npe tsis siab, tab sis rau xim luam ntawv, kev sau npe raug yog qhov tseem ceeb heev. Yog tias qhov tseeb overprinting tsis txaus, yuav muaj misalignment ntawm ntau yam xim ntawm cov ntaub ntawv luam tawm, dawb to ntawm cov xim blocks, ghosting ntawm me fonts, thiab lwm yam. Yog li ntawd, lub repeatability ntawm cov imagesetter yog ib qho tseem ceeb rau xim luam ntawv phaj. tseem ceeb.
Muaj ntau hom ntawv dav rau cov duabetters, feem ntau muaj yim-qhib, loj yim-qhib, tsis tu ncua plaub-qhib, loj plaub-qhib, thiab txawm folio thiab puv-qhib hom. Feem ntau, cov duab thaij duab tuaj yeem siv ntau hom yeeb yaj kiab sib txawv hauv qhov ntau hom ntawv. , nyob rau hauv thiaj li yuav hloov mus rau ntau hom kev xav tau thiab ua tiav lub hom phiaj ntawm kev txuag zaj duab xis. Cov ntaub ntawv raug thiab rov ua dua ntawm cov duabsetter muaj kev sib raug zoo nrog cov hom ntawv. Cov hom ntawv loj dua, qhov siab dua qhov yuav tsum tau ua kom raug, qhov nyuaj dua hauv kev tsim khoom thiab kev ua haujlwm, yog li tus nqi yuav nce exponentially.
Feem ntau, cov duab thaij duab nrog lub nruas sab hauv thiab sab nrauv tuaj yeem ua tiav cov ntaub ntawv raug siab, vim tias qhov kev ncua deb ntawm laser mus rau zaj duab xis yog ib txwm zoo ib yam. Txawm li cas los xij, lub laser beam ntawm lub imagesetter nrog lub winch qauv yog scanned los ntawm lub prism deflecting beam nyob rau hauv lub transverse kev taw qhia, yog li qhov kev ncua deb ntawm lub laser beam thiab nruab nrab thiab ob qho tag nrho ntawm cov zaj duab xis yog txawv. Qhov ntau dua qhov sib txawv ntawm ob qhov kawg, qhov ntau dua qhov nonlinear distortion, thiab yog li qhov yuam kev ntau dua. Yog li ntawd, nws feem ntau txwv tsis pub cov duab teeb tsa dav ntawm lub winch-type imagesetter tsis tuaj yeem tshaj plaub qhov qhib, thiab kev siv zog yuav tsum tau ua kom txo qis lub kaum sab xis ntawm lub laser beam thiab txo qhov deformation ntawm lub teeb pom kev.
Phototypesetting ceev
Imagesetting ceev feem ntau yog ntsuas hauv zaj duab xis pub ceev thaum kaw ntawm 1200dpi daws teeb meem. Cov duab thaij duab tshiab tuaj yeem khiav ceev heev, tab sis qhov no tsis yog tib yam uas txiav txim siab qhov ceev ntawm zaj duab xis, vim tias nws kuj raug txwv los ntawm qhov ceev ntawm RIP. Lub sij hawm siv los tso tawm ib qho layout yuav tsum sib npaug ntawm cov sij hawm siv los ntawm lub network xa cov ntaub ntawv, lub sij hawm siv los ntawm RIP los txhais cov layout, thiab lub sij hawm siv los ntawm cov imagesetter los sau, yog li cov imagesetter ceev tsuas yog cuam tshuam. ib feem ntawm lub sijhawm kaw.
Laser wavelength
Cov lasers feem ntau siv hauv cov duab thaij duab suav nrog helium-neon lasers nrog lub wavelength ntawm 633nm, liab semiconductor lasers nrog lub wavelength ntawm 650nm lossis 670nm, thiab infrared semiconductor lasers nrog 780nm infrared teeb. Lub laser wavelength txiav txim siab hom zaj duab xis siv, thiab txawm tias tus nqi ntawm zaj duab xis siv. Piv txwv li, lub domestic ammonia-neon laser phototypesetting zaj duab xis yog pheej yig tshaj, thiab yuav luag tag nrho cov ntawv phototypesetting siv cov zaj duab xis no, thaum lub infrared phototypesetting zaj duab xis yog kim thiab siv tsawg.
