Sau Koj Cov Qauv: Cov Lus Qhia Tseem Ceeb thiab Tricks Koj Yuav Tsum Paub
Kev txiav txim siab rau txheej txheem tsim
Xim Chaw
Thaum tsim nyob rau hauv ib puag ncig digital, qhov chaw xim xim yog RGB, muab ntau yam xim tsis zoo. Txawm li cas los xij, cov xim ntau yam ntawm CMYK plaub-xim number case txheej txheem siv nyob rau hauv kev luam ntau lawm yog txwv. Cov ntawv pov thawj muag muag nrog CMYK yog qhov tseem ceeb kom nkag siab tias koj tus qauv tsim yuav tshwm sim li cas hauv kev luam ntawv thiab kho koj qhov kev cia siab raws li. Tsis tas li ntawd, calibrating koj lub monitor yog qhov tseem ceeb los xyuas kom meej tias qhov koj pom zoo li cas koj lub tshuab luam ntawv luam tawm.
Thaum cov xim muaj nuj nqis tuaj yeem sib txuas lus thoob ntiaj teb los ntawm cov tshuab xws li Pantone Matching System, kev ua tiav cov xim sib xws yuav xav tau qhov sib ntxiv ntawm cov xim xim rau cov txheej txheem CMYK. Cov xim xim feem ntau yog siv rau hauv 2-xim teeb rau tej yam xws li daim npav lag luam, tab sis kev sib xyaw xim thib tsib rau hauv ib qho kev ua tiav tonal yog qhov yuav tsum tau tshwj xeeb thiab tuaj yeem raug nqi. Rau cov phau ntawv, cov xim kev cai feem ntau tsuas yog muaj nyob rau ntawm kev txiav txim offset.
DPI thiab PPI
Cov neeg tsim qauv digital ua haujlwm hauv pixels, thaum lub tshuab luam ntawv ua haujlwm hauv dots ib nti (DPI). Cov ntxaij vab tshaus siab (xws li cov duab Retina) coj txawv dua li ntawv. Qhov tseem ceeb sib txawv yog qhov loj thiab qhov ntsuas. Hauv ntiaj teb luam ntawv, ib yam khoom tsis yog 800 pixels dav; Nws yog 8 nti. Pixels lossis cov ntsiab lus sawv cev qhov ntom ntom, tsis sib piv. Muaj ntau yam cuam tshuam rau qhov yuav tsum tau ua kom ceev, xws li qhov loj ntawm cov khoom, saib qhov deb thiab tsim cov ntsiab lus.
Rau phau ntawv luam ntawv, 300 dpi yog tus qauv, tab sis rau cov ntawv tshaj tawm, 100 dpi yuav txaus vim saib qhov deb. Thaum xaiv cov dluab thiab exporting cov ntaub ntawv, xyuas kom meej tias lawv haum rau lub hom phiaj luam ntawv loj. Cov duab qis-dpi yuav saib tsis zoo yog tias lawv luam tawm loj dua li lawv tshwm sim ntawm qhov screen. Xav txog cov proportions thiab textures ntawm lub cev khoom thaum lub sij hawm tsim txheej txheem kom ntseeg tau tias cov ntsiab lus tsim nyog.
Tsim rau cov khoom siv lub cev
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias koj tab tom tsim ib qho khoom siv uas yuav tsum tau sib sau ua ke. Thaum tsim ib phau ntawv, aligning cov ntsiab lus ntawm lub gutter yuav nyuaj. Kev tsim ntawm lub vijtsam tiaj tiaj ua rau nws nyuaj rau kev twv seb qhov quav ntawm nplooj ntawv lossis qhov nkhaus ntawm lub hau yuav cuam tshuam li cas rau qhov layout. Txawm hais tias los ntshav thiab txiav cov txheej txheem, tsis muaj qhov tseeb. Thaum tsim koj qhov layout, xav txog lub cev ntawm koj phau ntawv. Nws yuav zoo li cas hauv tus nyeem ntawv txhais tes yog tias tus nyeem ntawv tsis tuaj yeem nteg nws tag nrho? Yuav ua li cas koj hloov mus rau txoj kev koj ob lub qhov muag navigate lub cev qhov chaw?
Tsib qhov yuam kev loj ntawm cov neeg tsim qauv tsim Cov ntaub ntawv luam tawm
1. Tsis muaj cov kab los ntshav. Thaum xa cov ntaub ntawv mus rau lub tshuab luam ntawv, nws yuav tsum muaj cov kab ntshav los tso cai rau lub tshuab luam ntawv tuav lub tshuab luam ntawv thaum nws dhau mus. Blurb's Adobe InDesign plug-in tau teeb tsa cov duab kos nrog cov kab tsim nyog los ntshav. Txawm li cas los xij, yog tias siv cov software sib txawv, xyuas kom koj cov ntaub ntawv muaj tsawg kawg yog 3 hli lossis 0.25 ntiv tes los ntshav thaum tsim rau ntawm ntug ntawm nplooj ntawv.
2. Cov ntaub ntawv tso zis thiab RIP chaw. Thaum koj tus qauv tsim muaj xws li pob tshab, gradients, lossis duab ntxoov ntxoo, nws yog ib qho tseem ceeb uas yuav tau nug koj lub tshuab luam ntawv txog nws qhov kev nyiam. Txhua lub tshuab luam ntawv siv qhov sib txawv raster duab processor (RIP), uas cuam tshuam li cas nws txhais cov ntaub ntawv hauv PDF thiab tsim qhov project. Thaum qhov no siv rau tag nrho cov ntaub ntawv luam tawm, pob tshab, shading, thiab xim gradients tuaj yeem nyuaj tshwj xeeb. Kev tuav tsis raug ntawm cov ntsiab lus no hauv cov ntaub ntawv luam tawm tuaj yeem ua rau cov txiaj ntsig tsis xav tau. Xyuas kom tseeb tias koj cov ntaub ntawv luam tawm tau sib xws nrog koj lub tshuab luam ntawv tshwj xeeb kom tsis txhob ua yuam kev.
3. Kev xaiv font. Muab hais tias peb cov ntxaij vab tshaus tuaj yeem tso saib cov ntsiab lus zoo dua li feem ntau cov inks thiab cov ntawv, nws yog ib qho tseem ceeb uas yuav tau xav txog koj cov kev xaiv font kom zoo. Ntxiv nrog rau qhov nyuaj ntawm kev tso cai font, nws tseem ceeb heev rau kev siv koj tus qauv font. Xyuas kom tseeb tias tus font koj xaiv thiab nws qhov loj me nyob twj ywm tom qab luam ntawv. Feem ntau cov tshuab luam ntawv muaj kev zam tshwj xeeb, thiab cov ntawv sau qis dua 6 cov ntsiab lus lossis cov kab mob stroke thiab cov serifs qis dua 1 taw tes yuav tsis pom vim tus cwj mem thiab ntawv zoo nkauj. Tshawb xyuas koj lub tshuab luam ntawv cov lus qhia kom paub tseeb tias koj ua tau raws li nws cov kev xav tau txij thaum pib.
4. Ncej. Thaum ib phau ntawv raug tsim, cov nplooj ntawv luam tawm ib tus zuj zus, sib sau ua ke, thiab tom qab ntawd txiav. Kev ua tiav ib tus ciam teb uas zoo kawg nkaus sib luag rau ntawm ntug ntawm nplooj ntawv thaum lub sijhawm luam ntawv thiab sib dhos yog qhov nyuaj thiab tuaj yeem ua rau nplooj ntawv-rau-nplooj thiab luam-rau-daim ntawv hloov pauv. Yog li ntawd, nco ntsoov ua yuam kev nyob rau sab ntawm kev ceev faj thiab txawm tias tsis txhob siv ciam teb uas vam khom nplooj ntawv ntug.
5.Total Ink Coverage (TIC). Zoo ib yam li cov txheej txheem luam ntawv lub cev, muaj cov kev txwv uas yuav tsum tau xav txog. Qhov kev ntxhib los mos thiab viscosity ntawm tus number case txiav txim siab seb nws siv li cas thiab siv sijhawm ntev npaum li cas kom qhuav. Cov ntawv muaj qhov txwv tsis pub nqus, uas txhais tau tias lawv tuaj yeem tuav tau qee yam ntawm tus cwj mem yam tsis muaj deforming lossis tsis pom tseeb. Tsis tas li ntawd, lub tshuab luam ntawv txwv tsis pub muaj tus cwj mem uas nws tuaj yeem tso tawm ua ntej lub taub hau luam tawm los yog daim ntawv jam tshwm sim.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum koj saib yuav pom cov xim dub sib sib zog nqus thiab cov xim zoo nkauj, kev luam cov ntawv no tuaj yeem nyuaj. Hauv CMYK txheej txheem luam ntawv, muaj kev txwv rau tag nrho cov number case, feem ntau tsis tshaj 300% ntawm tag nrho cov xim. Piv txwv li, lub tshuab luam ntawv tuaj yeem luam 100% cyan, 100% magenta, thiab 100% daj, lossis 50% cyan, 100% magenta, 50% daj, thiab 100% dub. Thaum tsim cov xim thiab opacity, koj yuav tsum nco ntsoov qhov no hauv siab thiab ua qhov tseem ceeb saturation raws li xim tseem ceeb.
Txoj hauv kev zoo tshaj plaws yog kom muaj kev sib tham nrog koj tus kws tshaj lij luam ntawv. Nws yog ib qho yooj yim los saib xyuas cov txheej txheem kev cuam tshuam nrog kev luam ntawv tsim, tshwj xeeb tshaj yog nyob rau hauv lub hnub nyoog ntawm cov luam ntawv digital uas cov txheej txheem tau yooj yim dua. Nws tsis yog ib qho teeb meem ntawm kev nias lub pob, nrog rau kev ua tib zoo saib xyuas koj txoj haujlwm tuaj yeem siv cov duab kos duab zoo nkauj thiab kos duab zoo nkauj luam tawm.
