Yog tias koj tshiab rau lub ntiaj teb ntawm kev luam ntawv, ib qho ntawm thawj yam koj yuav tsum paub txog yog DPI.Nws sawv rau dab tsi?Dots ib nti.Thiab vim li cas nws thiaj tseem ceeb?Nws yog hais txog tus naj npawb ntawm cov dots luam tawm raws li ib-nti kab.Qhov siab dua ntawm DPI daim duab, cov dots ntau dua, thiab yog li qhov ntse dua thiab qhov tseeb dua koj cov ntawv yuav yog.Nws yog txhua yam hais txog qhov zoo…
Dot thiab pixels
Raws li DPI, koj yuav hla lub sij hawm PPI.Qhov no sawv cev rau pixels ib nti, thiab nws txhais tau tias yog tib yam.Ob leeg yog ib qho kev ntsuas ntawm qhov kev daws teeb meem luam tawm.Qhov siab dua koj qhov kev daws teeb meem, qhov zoo dua koj cov ntawv luam yuav yog - yog li koj tab tom nrhiav kom mus txog qhov chaw uas cov dots, lossis pixels, tsis pom lawm.
Xaiv koj hom luam ntawv
Feem ntau cov tshuab luam ntawv tuaj nrog xaiv hom kev luam ntawv, thiab qhov no feem ntau yog ib txoj haujlwm uas tso cai rau koj luam tawm ntawm DPIs sib txawv.Koj qhov kev xaiv ntawm kev daws teeb meem yuav nyob ntawm seb hom printheads koj lub tshuab luam ntawv siv, thiab tus tsav tsheb luam ntawv lossis RIP software uas koj siv los tswj lub tshuab luam ntawv.Tau kawg, luam ntawv hauv DPI siab dua tsis tsuas yog cuam tshuam rau koj cov ntawv luam tawm zoo xwb, tab sis kuj yog tus nqi, thiab ib txwm muaj kev lag luam tawm ntawm ob.
Cov tshuab luam ntawv inkjet feem ntau muaj peev xwm ntawm 300 txog 700 DPI, thaum lub tshuab luam ntawv laser tuaj yeem ua tiav txhua yam ntawm 600 txog 2,400 DPI.
Koj qhov kev xaiv ntawm DPI yuav nyob ntawm seb cov neeg yuav mus saib koj cov ntawv luam li cas.Qhov ntau dua qhov pom qhov deb, qhov me me ntawm pixels yuav tshwm sim.Yog li, piv txwv li, yog tias koj luam tawm ib yam dab tsi zoo li daim ntawv qhia lossis daim duab uas yuav raug saib ze, koj yuav tsum xaiv txog 300 DPI.Txawm li cas los xij, yog tias koj luam tawm daim ntawv tshaj tawm uas yuav pom los ntawm ob peb taw deb, koj tuaj yeem tau txais deb ntawm DPI txog 100. Ib daim ntawv tshaj tawm pom los ntawm qhov deb dua, qhov twg 20 DPI yuav txaus.
Yuav ua li cas txog cov xov xwm?
Lub substrate uas koj luam tawm kuj tseem cuam tshuam rau koj xaiv qhov zoo tagnrho DPI.Nyob ntawm seb nws permeable npaum li cas, cov xov xwm tuaj yeem hloov qhov tseeb ntawm koj cov ntawv luam tawm.Sib piv tib DPI ntawm daim ntawv glossy coated thiab uncoated paper-koj yuav pom tias cov duab ntawm daim ntawv tsis muaj xim tsis yog ze li ntawm daim duab ntawm daim ntawv glossy.Qhov no txhais tau hais tias koj yuav tsum tau kho koj qhov chaw DPI kom tau txais tib theem zoo.
Thaum tsis ntseeg, siv DPI siab dua li koj xav tias koj yuav xav tau, vim nws zoo dua kom muaj ntau yam nthuav dav ntau dua li tsis txaus.
