Nyob rau hauv cov nqe lus ntawm inks:
1. Kev xaiv tus number case tsis tsim nyog, tus number case yuav tsum tau hloov;
2. Cov mem kua tsis nrawm dhau, xaiv tus number case qeeb-qhuav;
3. number case viscosity ntau dhau, xaiv tus number case viscosity tsawg.
4. Cov lag luam tsis zoo number case;
5. Nquag muaj tus cwj mem sib xyaw nrog cov kua cwj mem.
Thaum lub sijhawm luam ntawv, vim muaj kev nthuav dav thiab muag ntawm qhov hnyav, lub tshuab qhib mesh uas yuav tsum dhau tus number case yog txhaws, uas ua raws li phaj zaj duab xis thiab tiv thaiv tus number case kom dhau. Txhawm rau tiv thaiv hom teeb meem no, cov kua dej sib xyaw (tshwj xeeb yog cov number case qub) yuav tsum tau lim thiab rov siv dua nrog lub mesh ua ntej siv. Thaum rov siv lub phaj luam tawm siv, tus number case qub uas txuas rau ntawm daim phaj yuav tsum tau muab tshem tawm tag nrho. Thaum khaws cia cov ntawv luam tawm tom qab luam ntawv, ntxuav nws kom huv (suav nrog ntxig). Yog tias koj ua raws li tau piav saum toj no, kev sib tsoo ntawm inking ntoo yuav tsis tshwm sim.
Yog hais tias qhov taub ntawm lub taub hau kawg ntawm cov tswj hwm ntse raug puas ntsoog, lub ntsej muag yuav tshwm sim raws cov kev taw qhia kev txav ntawm scraper. Tshwj xeeb tshaj yog thaum luam tawm cov ntaub ntawv pob tshab, yuav muaj qhov cuab kev tsis sib xws. Yog li ntawd, pem hauv ntej kawg ntawm tus ntse ntse yuav tsum muaj kev tiv thaiv zoo los ntawm kev puas tsuaj. Yog tias nws raug puas, nws yuav tsum ua tib zoo sau nrog lub tshuab grinder.
Qhov tsis sib xws ntawm lub rooj luam ntawv tseem yuav cuam tshuam cov inking kev sib txawv. Convex number case txheej yog nyias, thiab cov kua nplaum uas muaj concave yog tuab. Qhov tshwm sim no tseem hu ua tsis yog inking. Tsis tas li, yog tias cov hmoov av ua raws li qhov chaw nyob sab hauv qab los yog lub tshuab luam ntawv, cov lus sau los saum toj tsis ua haujlwm kuj tuaj yeem tshwm sim. Lwm qhov laj thawj yog lub vijtsam luam ntawv phaj ntawm lub vijtsam luam ntawv raug kaw, thiab lub vijtsam yuav tsum raug ntxuav; lub tshuab luam ntawv siab ntawm lub tshuab luam ntawv tsis txaus, thiab lub tshuab luam ntawv siab yuav tsum tau nce;
