Crease yog txheej txheem ntawm kev siv cov grooves ncaj nraim rau daim ntawv luam. Lawv raug siv rau hauv daim ntawv hauv daim ntawv ntawm cov caws pliav uas khiav raws kab kab.
Qhov xav tau kev creasing yog txiav txim siab los ntawm qhov yooj yim yooj yim thaum folding raws kab ntawm cov duab los yog ntawv nrog qhov ntom ntawm 150 g / m 2. Qhov zawj ua thaum lub sijhawm muab qhab nia yog hu ua "loj" thiab tso cai rau koj kom yooj yim thiab sib npaug ntawm ob sab ntawm daim ntawv.
Creasing yog ib qho haujlwm uas tuaj yeem ua tsis tau tsuas yog nrog ntawv, tab sis kuj nrog ntau yam ntaub ntawv. Piv txwv li, cov ntawv laminated, interlaced cardboard, cov ntawv yas, ntau hom yeeb yaj kiab yuav raug creasing.
Qhov txawv ntawm creasing thiab folding
Folding, xuas nrig ntaus thiab creasing yog cov txheej txheem siv hauv kev tsim cov khoom lag luam thiab cov ntawv sau. Cov txheej txheem no yog qhov tseem ceeb rau kev tsim cov ntawv caw, phaib nkag, lub thawv khoom plig thiab hnab, nrog rau kev tsim cov khoom luam tawm ntau ntau.
Nyob hauv kev lag luam luam ntawv, lub ntsiab lus ntawm lo lus "creasing" yuav tsum tsis txhob totaub nrog folding. Cov txheej txheem no sib txawv kiag li, ua rau cov khoom siv sib txawv thiab hauv ib ntu tshwj xeeb.
Raws li txoj cai, creasing yog txheej txheem ua ntej folding. Nqa tawm creasing ua rau nws yooj yim rau txheej txheem thaum folding.
Txoj kev folding yog siv los ua ib phau ntawv lossis lwm yam khoom luam tawm los ntawm cov ntawv luam tawm lawm. Los ntawm folding nws yog ua tau kom ua tiav folds. Siv txoj kev no, koj tuaj yeem yooj yim tsim ib daim ntawv qhia, phau ntawv lossis ntawv xov xwm los ntawm ntau phau ntawv sau.
Folding tau cuam tshuam los ntawm qhov tuab thiab ntim ntawm daim ntawv, cov ntsiab lus noo noo thiab cov kev taw qhia ntawm cov fibers mus rau quav, tus naj npawb ntawm quav thiab txoj kev folding.
Thaum qhab nia tiav
Creasing hloov cov pa folding tshuab thaum muaj kev cuam tshuam ntawm daim duab qhia ntawm daim ntawv lossis thaum siv cov khoom siv duab los qhia. Nws yog ib qho tsim nyog los txiav txim siab qhov xav tau ntawm nws ntawm qib prepress txhawm rau ua cov cim tshwj xeeb thaum lub sijhawm teeb tsa.
Crease yog txheej txheem uas tiv thaiv cov quav los ntawm kev tawg ntawm tus number case thiab muab cov ntawv luam tawm zoo nkauj.
Qhov kev txiav txim yog ua nrog kev pab los ntawm blunt disc riam los yog daim duab plaub ntsia rau ntawm lub tshuab creasing. Hauv kev ua haujlwm, lub tshuab nqa tawm indentation thiab compaction ntawm cov khoom.
Creasing khoom muab faib ua teb thiab cuam tshuam. Cov cuab yeej cuam tshuam feem ntau yog siv rau hauv cov khoom me me, thiab cov khoom siv teb yog qhov tseem ceeb rau kev ua haujlwm loj.
Txoj kev ua kom nrawm nrawm
Yog hais tias txoj kab loj yog nyob rau sab perpendicular rau daim ntawv fibers, nws yuav tsum tau siv phau ntawv creasing. Kev siv cov txheej txheem phau ntawv tso cai rau koj kom ua tiav qhov tseebquav kab thiab tiv thaiv daim ntawv los ntawm pliaj creases.
Kev siv phau ntawv creasing yog siv los tsim cov ntawv me me lossis rau kev tso tawm ib tsab ntawv tshwj xeeb. Txoj kev phau ntawv ntawm creasing, raws li qhov nyuaj, yog me ntsis kim dua lub tshuab.
Crease tool
Conventionally, creasing cov cuab yeej txawv ntawm ib sab ntawm lub quav, uas yog, muaj cov cuab yeej los kos ib kab fold los ntawm sab hauv ntawm daim ntawv los yog los ntawm sab nraud.
Lub rooj tsavxwm creasing yog muag nyias, thiab tsis yog cov koom haum luam ntawv tuaj yeem yuav nws. Kev yooj yim ntawm kev siv thiab tsis muaj kev txwv ntawm daim ntawv hom ua rau nws siv tau rau hom loj.
Lub rooj tsavxwm suav nrog daim duab peb sab tshwj xeeb siv rau kev tsim cov hnab ntawv ntawm ntau qhov ntev thiab dav. Lub rooj tsavxwm muaj cov cim siv.
