Cov ua kua zaub ntawm lub ntsiab nyob hauv qab yog raws li nram no:
Xim xim yog cov khoom siv khov hauv cov mem kua, uas yog cov xim txhim kho cov kua cwj mem, thiab feem ntau yog dej-ua kom tsis muaj xim. Kev saturation, tinting zog, pob tshab thiab lwm yam khoom ntawm tus number case xim zoo hais txog cov khoom ntawm cov xim muaj xim.
Cov ntawv ci yog cov ua kua ua kua ntawm tus number case, thiab cov xim yog cov thauj khoom. Hauv cov txheej txheem luam ntawv, phau ntawv nqa cov xim pleev xim, los ntawm tus cwj mem ib nrab ntawm lub tshuab luam ntawv, los ntawm tus number case roller, luam ntawv phaj, thiab dov mus rau hauv txheej los tsim zaj duab xis number case, uas yog tsau, ziab thiab nplaum rau hauv txheej. Lub gloss, dryness, thiab cov khoom siv lub zog ntawm tus number case zaj duab xis yog cuam tshuam nrog kev ua tiav ntawm phau ntawv binder.
Tus neeg sawv cev ntxiv nyob rau hauv tus number case yog txhawm rau txhim kho qhov luam tawm ntawm tus number case, xws li viscosity, adhesion, thiab dryness.
Nrog rau kev txhim kho tshuab luam ntawv, ntau hom ntawm inks txuas ntxiv nce, thiab muaj ntau txoj kev faib tawm. Yog tias faib raws li cov txheej txheem luam ntawv, muaj tsib hom nram qab no:
Letterpress printing number case: tus cwj mem dub rau phau ntawv thiab ntawv sau, tus cwj mem dub rau kev sib hloov, xim number casepress, thiab lwm yam.;
Lithographic luam ntawv inks: offset luam ntawv ci ci inks, offset luam ntawv qeeb mentshis, thiab lwm yam.;
Gravure printing number case: thaij duab thaij duab, kos duab kos xim, thiab lwm yam.;
Serigraphy printing number case: transcription printing number case, silk screen printing number case, thiab lwm yam.;
Kev luam ntawv inks tshwj xeeb: ua npuas dej inks, sib nqus inks, fluorescent inks, inks conductive, thiab lwm yam.
Cov txheej txheem number case teeb meem ntau dua. Feem ntau, cov tshuaj pleev xim, cov hlua khi thiab ntau yam sib xyaw ua ke tau sib xyaw nrog qee qhov sib faib ua cov roj pleev, thiab tom qab ntawd rov ua dua rau hauv cov menyuam zeb lossis hauv cov menyuam zeb kom ua cov xim tuaj ua kom cov xim zoo nkauj ua kom tawg mus rau hauv phau ntawv qhia.
