Nyob rau hauv sab sab ntawm daim duab 1, muaj peb cov khoom siv straw, dub teb, grey teb thiab dawb teb calibration pipette, uas muaj peev xwm paub qhov dub thiab dawb teb calibration ntawm daim duab.
Nceeg ua tau raws li peb lub luag haujlwm nram qab no
1. Duab teeb siab
Tus Curve nkhaus tuaj yeem kho kho qhov tob ntawm daim duab xim, tshwj xeeb tshaj yog rau kev hloov ntawm qee cov duab tho txawv.

Yog li ntawd, cov duab ntawm cov duab poob, thiab qhov sib txawv ntawm lub suab tsaus nti tsawg dhau thiab qhov theem tsis txaus. Ua li no, peb yuav tsum pib ua qhov sib txawv ntawm lub suab tsaus, thaum uas ua kom txhua tus ci ntsa iab, ua cov xim ntawm txhua txheej sib zog. Qhib qhov nkhaus dialog box, siv CMYK nws cov kauj tsoo raws li cov khoom ua kom haum, rub tawm qhov cwj pwm, thiab hloov cov ciaj thiab cov txiaj ntsim raws li qhia hauv daim duab 3. Nws pom tau tias daim duab 3 yog qhov zoo tshaj li qhov tshwm sim ntawm daim duab 2. Cov tag nrho cov duab meej, cov ntsiab lus yog ntau tshaj, thiab qhov txawv kuj qhib.
2. Kho xim ncaj qha
Cov cuab yeej nkhaus no tuaj yeem kho qhov xim xim ntawm cov duab los sis cov xim ua haujlwm ntawm lub suab nrov, tab sis lub peev xwm los kho qhov xim txawv ntawm qhov xim tsis zoo. Vim tias nws yog qhov khoom ntawm cov channel, tsis yog xim ntawm qhov khoom. Cia peb saib ib qho piv txwv. Daim duab 4 yog daim duab ntawm ib tug poj niam. Peb paub los ntawm lub ntsej muag uas C2% M35% Y26% K0%, nws M yog loj dua Y.
