A: Hauv Photoshop, qhov chaw ntawm plaub-xim dub yog tshwj xeeb heev. Raws li qhov uas Photoshop 7.0 muaj kev txhawj xeeb, lub cim pheej yig ntawm qhov software yog ib txwm: C75 M68 Y67 K90.

Es tsis txhob, lawv luam tawm nrog 100% dub number case los ntawm kev txo qis, ces lawv tag nrho cov yeeb yam Qhov xim xim: liab tone.
Ob lub ntsiab lus ntxiv los ntxiv yog:
Vim tias tag nrho cov xim dub grey yog xim liab nruj me ntsis, yog li hauv Photoshop, koj xav tau qhov xim zoo nkauj grey, nws yog qhov zoo tshaj rau ntxiv ib qho kev faib ua feem ntawm xiav (C);
Rau cov ntawv nyeem, peb txhua tus paub tias ntau cov xim dub yog yooj yim luam thiab muab tshuaj, yog thaum tsim cov ntawv luam tawm (luam tawm) hauv Photoshop (tshwj xeeb tshaj yog cov ntawv sau me me), peb yuav tsum siv 100% ib zaug dub.
Yog tias muaj thaiv nplhaib, nws yuav muab xa mus rau lub tuam txhab ua yeeb yaj kiab thiab yuav muaj cov pob nyob rau hauv grey strip. Cov ntaub ntawv yog K20, thiab cov dots ntawm cov zaub tsis tau pom. Qhov tob ntawm cov xim yog tej zaum tswj los ntawm qhov ceev ntawm cov dots. Qhov screen qhia tau xim, tab sis cov ntawv luam tawm yog raws li cov teev. Yog tias koj saib nws nrog ib lub iav tsom iav, qhov xim ntawm txhua qhov teev ua tau yog xim xim, tab sis lawv faib yog tuab.
