Kev sau cov ntawv yooj yim
Nyob rau hauv cov txheej txheem luam ntawv, lub nrig ntawm cov duab ib nrab yog kho ntawm qhov sib txawv ntawm cov dots. Los ntawm sib xyaw CMYK plaub-xim dots, koj tuaj yeem tso saib tus zauv ntawm cov xim.
Nws muaj ob hom kev lag luam uas tam sim no siv nyob rau hauv cov txheej txheem luam ntawv: amplitude modulation (AM) thiab kev ua haujlwm ntau zaus (FM).
AM qhov chaw
AM qhov chaw yog tam sim no siv ntau tshaj plaws network. Nws cov density ntawm dots yog tsau, thiab ntxoov xim yog qhia los ntawm kho qhov loj me ntawm cov dots, yog li ua tau zoo ntawm kev hloov ntawm lub suab. Hauv kev luam ntawv, kev siv AM chaw tsim nyog yuav tsum tau saib xyuas kev sib npaug zos, teeb duab, pob qhov rooj, thiab kab xev.
Dot loj
Qhov loj daig yog txiav txim siab los ntawm cov kev pabcuam ntawm cov teev, los yog tus lej nqi. Feem ntau hais lus, nws yog ib txoj kev cai uas siv "ua kom tiav" raws li kev ntsuas. Piv txwv li, 10% ntawm qhov kev pab them nqi yog hu ua "10% outlet", ib qho hluav taws xob nrog 20% kev pabcuam yog hu ua "20% outlet", thiab qhov kev tawm suab nrog 0% yog hu ua "absolute network" qhov kev pab them nqi ntawm 100% ntawm lub network yog hu ua "nyob rau hauv field."
Lub suab ntawm cov teeb meem luam tawm feem ntau muab faib ua peb theem: lub suab nrov, lub suab nrov, thiab lub suab tsaus nti. Cov kev pabcuam teebmeem ntawm qhov tseem ceeb yog li 10% txog 30%; qhov kev pab them nqi ntawm half-hour yog li 40% rau 60%; thiab qhov tsaus nti yog 70% txog 90%. Lub qhov net thiab daim teb seem muab faib ua ke.
Dot puab
Qhov teeb duab hauv cov ntawv luam tawm tsis yog ib qho zoo nkaus xwb uas txhua tus xav txog. Nws tuaj yeem faib ua peb hom: square, round, thiab rhombus nrog rau cov duab uas tshwm los ntawm cov dots ntawm 50% inking rate.
Square dots yog zoo li tus chessboards nrog 50% kev pab them nqi. Cov phom nws yog ntse, thiab nws lub peev xwm los nthuav qhia qib muaj zog. Haum rau cov kab, graphics thiab qee cov duab uas nyuaj.
Nyob rau hauv cov ntaub ntawv ntawm ib ncig dot, xws li nyob rau hauv lub suab nrov los yog nyob rau hauv nruab nrab cov laus, lub tsuas yog ywj siab thiab tsuas yog ib feem nrog kev cob cog. Yog li no, qib theem rau qib tsuas yog neeg pluag, thiab nws tsis tshua siv plaub-xim luam ntawv.
Cov pob zeb diamonds zoo li sib xyaw cov tawv nqaij ntawm cov square dots thiab cov mos-kev hloov ntawm cov voj voos. Cov kev hloov xim yog ntuj, uas yog tsim rau kev ua tau zoo ntawm cov duab thiab cov duab.
Dot kaum
Nyob rau hauv cov phaj printing, qhov xaiv ntawm lub kaum sab xis muaj lub luag haujlwm tseem ceeb heev. Xaiv qhov teeb meem tsis zoo no yuav ua rau muaj kev cuam tshuam kev cuam tshuam.
Cov voj voog uas muaj tshaj plaws yog 90 degree, 15 degrees, 45 degrees, thiab 75 degrees. 45-degree network muaj qhov kev kawm zoo tshaj plaws, nws ruaj khov thiab tsis tuaj dull; qhov 15 degree thiab 75 degree angle stability muaj ntau zuj zus, tab sis qhov pom kev nyhav tsis yog sib npaug; 90 degree kaum sab xis yog qhov tseem ruaj khov, tab sis qhov muag pom tau zoo dhau lawm Tsis muaj qhov zoo nkauj.
Yog tias ob lossis ntau ntau hom kev dots raug muab tso ua ke, yuav muaj kev cuam tshuam kev sib nraus. Thaum cov cuam yog loj txaus los cuam tshuam cov tsos ntawm daim duab, qhov sib txawv "rhizard qauv" tshwm.
Feem ntau, thaum lub kaum ob qhov sib txawv ntawm ob hom ntawm tsuas yog 30 degrees thiab 60 degrees, tag nrho kev cuam tshuam kev cuam tshuam yog tseem zoo nkauj dua; qhov dot angle txawv ntawm 45 degrees yog tom ntej; Thaum cov kaum sib txawv ntawm ob qhov tsuas yog 15 degrees thiab 75 degrees Thaum cov kev cuam tshuam fringes tuaj yeem ua kom cov duab puas.
Dot naj npawb
Tus naj npawb ntawm cov voj voog txiav txim siab qhov ua tiav ntawm daim duab, zoo li kev daws teeb meem. Tus kab ntau hom yog siv raws li nram no:
Kab 10-120: Cov luam tawm tsis zoo, cov duab luv ntev xws li cov ntawv tho thiab cov zog yog luam tawm cov ntawv xov xwm lossis ntawv tawv nqaij, thiab cov ntaub ntawv xov xwm thiab cov ntaub ntawv muaj ntaub ntawv.
150 kab: Cov plaub-xim luam ntawv feem ntau yog siv cov ntaub ntawv no, txhua hom ntawv muaj.
Kab 175-200: exquisite albums, pictorials, thiab lwm yam., Feem ntau luam ntawm coated ntawv
250-300 txoj kab: Qhov tseem ceeb tshaj plaws albums, thiab lwm yam., Feem ntau luam ntawm cov ntawv pov thawj thiab cov ntawv tshwj xeeb.
Cov nram qab no yog cov nyhuv ntawm cov duab nyob rau hauv ntau ntau kab kab mob (cov nyhuv ntawm qhov kev tshuaj ntsuam yog qhov tiag tiag, tsuas yog rau qhov siv)
Ntsuam xyuas qhov point point
Qhov kev tshuaj ntsuam xyuas lub ntsiab lus yog qhov kev ntsuam xyuas tshiab tsim txij thaum xyoo 1990. Nws qhov txawv ntawm qhov kev ua haujlwm ntawm qhov teeb meem ntawm lub network yog tias qhov loj ntawm lub vijtsam npo ntawm qhov kev tshuaj ntsuam ntawm lub network yog tsau, thiab nws yog tau los ntawm kev tswj lub denseness ntawm cov ntsiab lus hauv lub network. Cov dots nyob rau hauv lub highlights yog sparse, thiab cov dots nyob rau hauv tus duab ntxoov ntxoo laus yog ntom.
Muaj ntau npaum li cas los ntawm lub webscope.
Ib-kaum ntawm kev sib koom tes: Tsuas yog peb qho zoo sib xws ntawm ob qho ntawm lub network.
Zengcheng.com: Tsuas yog ob qhov sib txawv ntawm qhov kev tawm ntawm ob qho chaw ntawm kab pheeb ces kaum.
Peb-kaum ntawm nets: Tsuas yog ob tug 1.5-square-dot nets raug muab tso rau ntawm ob lub kaum ntawm kab pheeb ces kaum.
Plaub-kaum ntawm cov nets: Tsuas yog 1.25 tus sib npaug ntawm cov nets raug muab tso rau nruab nrab ntawm ob qho ntawm cov kab txuas ntawm kab pheeb ces kaum.
50% ntawm cov nuj nqis: Tsuas yog ob tug nets ntawm tib lub loj tib si raug muab tso rau ntawm ob sab zus.
Ib-tenth network sib raug rau Jiucheng. Tshooj ob ntawm lub network tau sib raug mus rau Bacheng. Lub 30% network sib raug mus rau Qicheng. 40% ntawm cov lej sib raug mus rau 60% ntawm qhov net. Tsuas yog qhov luaj li cas ntawm qhov kev tshaj tawm xwb yog qhov txawv ntawm qhov kev ncua deb ntawm lawv.
(Ib qho kev txiav txim siab ntawm 300 leej, peb paub hais tias nws hais tias txhua tus ntiv tes muaj 300 tawm square pixels hauv txhua qhov kev coj ua Tom qab daim duab loj lawm, nws yuav pom tias nws muaj ntau cov qhov sib txawv ntawm ntau qhov ntau thiab tsawg. cov teeb meem luam tawm yog tsim los ntawm cov dots, tus najnpawb ntawm cov kab ntawv luam tawm yog hais txog cov xov tooj kab ntawm ib nti hauv kab rov tav los sis ntsug ntawm qhov teeb meem ntawm cov ntawv luam tawm, uas yog, cov xov tooj ntawm lub vev xaib. vim tias cov kab ntawv tshaj tawm ntawm cov xov tooj yog kab / Kab, lossis LPI rau luv luv, piv txwv li, 150 Lpi txhais tau hais tias muaj 150 lub voj kab hauv ib nti.Uas cov duab thaij duab, qhov loj dua cov vijtsam, qhov ntau ntawm cov vijtsam, ntau qhov ntxiab qhov ntxig li yog qhov ntau dua ntawm qhov kev qhia, qhov loj dua qhov dot, ntxaum qhov xim ntawm qhov kev qhia, thiab ib tsos tsaus tsawv txheej, thiab cov me me cov dots, sib zog dua cov xim ntawm kev qhia, lub zog th e uas muaj tuaj txheej, kab lus (Lpi) thiab qhov daws teeb meem (Dpi). ) Hais txog 1: 1, xws li 150 kab ntawm daim duab yuav tsum tau hais txog 300Dpi kev daws teeb meem. Kev daws teeb meem yog ob zaug ntawm cov kab. Yog hais tias koj tsis tau xyuam xim rau txoj kev xav, nws muaj peev xwm to taub raws li qhov ceev ntawm zaj duab xis los yog kua!)
Inter-color: Cov xim sib xyaw npaj los ntawm kev tov ob hom xim hu ua inter-colour or secondary secondary. Piv txwv, R, G, B, M80%, Y70%, C20%, thiab Y80% tuaj yeem raug hu ua inter-xim. Xim no tseem hu ua secondary xim
Duplex colour: Cov xim uas ua los ntawm kev sib tov nrog cov xim ntawm cov xim, lossis cov xim uas ua rau nws sib tov nrog ob qho xim sib txawv yog hu ua ib qho xim ntawm polychromatic los yog tertiary. Nyob rau hauv qhov tseeb, lub xim polychromatic yog ib qho sib xyaw ntawm peb lub ntsiab xim, tab sis nws yog raws li ntawm cov xim thawj.
Complementary colour: Thaum ob hom xim yog tov, lawv dub, thiab ob xim yog complementary. Cov xim ntawm ib qho ntawm peb lub ntsiab xim thiab lwm qhov ob hom xim yog ib qho xim sib nrauj. Piv txwv, M thiab G yog cov xim sib txuam. Qhov ob ntxoov ntawm lub teeb, yog hais tias tov rau daim ntawv dawb, yog sib sau ua ke rau ib leeg.
Dab tsi yog qhov cuab yeej cuab tam raws li? Qhov sib txawv ntawm Choke thiab Spread nyob qhov twg? Dab tsi txhob cia tseg?
(1) Ntsuas kev tswj yog ua nyob rau ntawm qhov chaw uas muaj ob lub xim xa mus. Lub shrinkage los yog nthuav ntawm nws foreground (los yog tom qab), hollowing tawm, los yog muab nchuav tag nrho yog tag nrho hu ua qhov cuab yeej cuab tam. Yuav kom tsis txhob glazing ntawm tus sib tshooj, qhov cuab yeej cuab tam yuav tsum yog me ntsis loj tshaj plaub-xim qhov tseeb ntawm cov ntawv xovxwm. Vim yog qhov sib txawv ntawm kev luam luam tawm hauv ntau hom xim prints, nrog rau cov lus tshaj tawm thiab cov tshuab luam ntawv, ntau dua qhov teeb meem ntawm cov ntawv luam tawm, qhov ntau dua cov lus tshaj tawm ntawm cov ntawv sau npe thiab txo qis dua tus nqi. Lub Tebchaws As Mes Lis Kas Printing Service thiab luam ntawv tau luam tawm cov kev qhia txog qhov tseeb. Piv txwv: sheetfed offset printing, kev siv cov ntawv xov tooj dotline tooj yog 150lpi, qhov cuab yeej cuab tam yog 0.08 hli; Cov ntawv xov xwm offset ntawm lub xov tooj, cov xov tooj ntawm 100lpi, tus nqi ntaiv yog 0.15mm.
(2) Shrinkage yog qhov nce ntawm thaj chaw ntawm (xim xim) tom qab ntawd nws yuav nkag mus rau hauv qhov tsaus ntuj nti (ntawv los yog cov duab) ntawm tus ciam teb, thaum tuav cov duab ntawm cov pauv teeb meem tsis hloov.
Qhov kev nthuav dav yog kom muaj thaj tsam ntawm qhov sib txawv ntawm qhov sib tw, kom nws yuav ua rau thaj chaw tom qab nrog xim ib tsos tsaus tsawv nyob ntawm tus ciam teb, thaum tuav tus qauv ntawm tus qauv qhia txog yav dhau los.
(3) Cia khoob thaum tom qab dub, thiab lub foreground yog hollowed tawm, peb ntxoov CMY yuav tsum tau dealt nrog thaum npliag, kom lub foreground contour txhais los ntawm cov monochrome dub version.
