【Technology】 Cov ntawv nplaum tau luam tawm hauv Cov Ntawv nplaum uas siv daim ntawv nplaum

Hauv kev luam ntawv, qee zaum peb siv cov ntawv luam tawm nrog cov ntawv offset cov khoom no. Yog li niaj hnub no peb yuav qhia cov yam ntxwv thiab kev siv ntawm cov khoom no kom meej:

Raws li Adhesive Stickers luam tawm teeb meem, nws tsuas yog ua ke nrog cov yeeb yaj kiab yas thiab ntawv, uas dhau los ua cov khoom lag luam zoo sib xyaw cov ntawv thiab yas, txhim kho cov xwm txheej thiab cov ntawv zoo. Npog nrog daim ntawv tsuas yog cov ntawv tsis muaj coated, daim ntawv coated thiab daim ntawv dawb.

Offset ntawv kev ntxhib los mos yog opaque, scalability yog me me, du, yog cov ntawv luam ntawv zoo dua. Offset ntawv yog cov ntawv siv los ntawm kev luam ntawv offset los luam cov npog, cov ntawv tshaj tawm, cov ntawv tshaj tawm, cov cim lag luam, cov ntaub ntawv hauv nruab nrab, daim duab qhia chaw, cov ntawv tshaj tawm, cov khoom ntim khoom thiab cov ntawv sau ntawm cov ntawv thiab cov ntawv sau. Offset ntawv yog tsim rau ntau xim luam ntawv.

Cov ntawv tsis muaj coated yog muab faib ua ob sab ntawm cov ntawv uas tsis muaj coated thiab ib sab ntawm cov ntawv tsis muaj coated, thiab muab faib ua cov ntawv tiaj tus (cov ntawv ntawv) thiab cov ntawv web. Ob chav sided offset ntawv feem ntau siv kom muaj nuj nqis 70, 80, 90, 100, 120g / m2 thiab lwm hom, ib leeg-sab offset ntawv feem ntau siv quantitative 50, 60, 70, 80g / m2 thiab lwm hom, noo noo 4% ~ 9 feem pua. Phaj offset ntawv 500 rau ib ream, txhua ream ntawm daim ntawv hnyav raws li daim ntawv kom muaj nuj nqis thiab specification.

Raws li tus yam ntxwv ntawm offset luam ntawv, qhov zoo thiab luam ntawv tsim nyog ntawm offset ntawv yuav tsum ua raws li cov hauv qab no:

(1) Cov ntawv siab zog, dej tsis kam. Offset luam ntawv ntawm daim ntawv nro, lub zog saum npoo ntawm daim ntawv yog siab, kev ntxhib los mos yog nruj, daim ntawv tsis tso cai rau poob hmoov plaub hau, thiaj li tsis ua rau paste version. Daim ntawv lub zog tsis txaus, daim ntawv fiber ntau thiab muab tub lim yuav lo rau saum npoo ntawm cov menyuam roj hmab hauv cov txheej txheem ntawm embossing, ua rau cov ntawv luam tsis zoo thiab daim pam fouling. Offset luam ntawv muaj cov txheej txheem ntub dej, uas yuav tsum muaj qee yam dej tsis kam ntawm daim ntawv.

(2) daim ntawv nthuav dav yog me me, tawv tawv yog loj. Daim ntawv nthuav dav yog hais txog tus nqi hloov pauv loj tom qab ntub thiab ziab. Kev nthuav dav tus nqi yog qhov cuam tshuam ntawm ntau qhov xim overprinting raug, thiab cuam tshuam rau qhov zoo ntawm zaj duab xis. Offset luam ntawv number case viscosity loj dua, yog tias daim ntawv tawv tsis loj txaus, daim ntawv tsis yooj yim cais tawm ntawm cov menyuam roj hmab tom qab luam ntawv.

(3) Daim ntawv saum npoo yog du thiab tus cwj mem nqus yuav tsum tsis txhob siab dhau. Uncoated daim ntawv nto tsis sib luag, tsis sib luag fiber ntau faib, yuav ua rau cov ntawv sau thiab cov ntawv luam tawm tsis muaj zog, cov hierarchy tsis meej. Offset ntawv number case absorption siab dhau lawm, number case nyob rau hauv cov khoom sib txuas sai sai rau hauv daim ntawv, cov xim pigment tso rau ntawm daim ntawv, ua rau tsis zoo luam ntawv, luam ntawv, luster thiab lwm yam teeb meem zoo. Offset luam ntawv number case tsuas yog los ntawm oxidation polymerization conjunctival, pigment particles qhwv thiab qhuav, tsuas yog ib feem me me ntawm daim ntawv nqus thiab qhuav.

(4) daim ntawv zoo nkauj, nruj zoo nkauj. Daim ntawv zoo li yuav tsum tsis txhob muaj wrinkles, streaks, me ntsis, lub teeb ntsiab lus, tawg, qhov, xuab zeb, impurities, xws li nruj kev ntxhib los mos, dawb uniform, sizing thiab polishing zoo.
