Daim ntawv me me compatibility yog hais txog ntau yam ntawm daim ntawv qhov ntev uas lub tshuab luam ntawv lossis cov khoom siv ntau yam tuaj yeem txhim kho cov txheej txheem - feem ntau teev raws li qhov siab tshaj plaws thiab qhov tsawg kawg nkaus txhawb. Kev siv daim ntawv sab nraud qhov no yuav ua rau muaj kev noj zaub mov tsis zoo, kev sib raug zoo, lossis kev puas tsuaj rau cov khoom siv. Thaum xaiv A3 daim ntawv rau kev luam ntawv hauv chaw ua haujlwm, cov txheej txheem hauv qab no yuav tsum tau ua nruj me ntsis kom ntseeg tau tias kev ua tau zoo, cov duab zoo, cov cuab yeej siv tau ntev, thiab cov ntaub ntawv ruaj khov.
1. Qhov hnyav (grammage)
Cov tshuab luam ntawv electrostatic feem ntau xav tau ntawv nrog lub hauv paus hnyav ntawm 64-80 g / m². High- qauv kawg tuaj yeem ua kom haum rau ntau qhov dav (50–200 g / m²); Txawm li cas los xij, kev xaiv yuav tsum ua raws li cov chaw tsim khoom tshwj xeeb rau cov cuab yeej tshwj xeeb. Kev sib txawv tuaj yeem cuam tshuam kev noj qab haus huv kev ntseeg tau thiab toner adhesion.
2. Nto tiav thiab txheej
Qhov nruab nrab gloss gloss yog siv tau rau kev luam ntawv monochrome; Txawm li cas los xij, ntau qhov smoothness impedes toner fixation thiab ua rau cov keeb kwm yav dhau. Rau ib qho - kev luam ib sab, ib daim ntawv -coated yog txaus. Rau duplex (ob -sided) luam tawm, ob npaug -coated ntawv yog pom zoo kom ua kom zoo ib yam toner adhesion ntawm ob qhov chaw. Kev dawb yuav tsum ua tau raws li ISO 2470 cov qauv (feem ntau ntau dua lossis sib npaug li 90% ISO ci ntsa iab) kom pom qhov sib txawv thiab nyeem tau.
3. Fiber ntom ntom thiab tsim
Daim ntawv yuav tsum muaj cov qauv zoo sib xws, nruj nreem khi fiber ntau. Cov fibers xoob dhau los yog tawg ua rau txo qis tensile lub zog, ua kom muaj plua plav, thiab cuam tshuam cov ntawv sib cais- ua rau muaj kev sib tsoo thiab sib kis ntawm cov khoom siv kho qhov muag (xws li, cov iav scanner, photoconductor nruas). Xws li kev sib kis degrades duab fidelity (xws li, grey keeb kwm yav dhau, streaks) thiab accelerates hnav. Tsis tas li ntawd, qhov tsis zoo ntawm fiber ntau cuam tshuam kev ruaj ntseg archival thiab ntev - lub sij hawm legibility ntawm cov ntawv luam.
4. Striffness (Bending Resistance)
Kev tawv nqaij-tsis yog grammage nkaus xwb- yog qhov tseem ceeb rau kev thauj mus los ntawm cov ntawv nyuaj. Ob daim ntawv nrog qhov hnyav tib yam (piv txwv li, 70 g / m²) tuaj yeem sib txawv hauv kev khoov tsis zoo vim muaj qhov sib txawv ntawm fiber ntau, ntaus degree, thiab calendering. Tsawg- daim ntawv tawv tawv yog qhov yooj yim rau curling, wrinkling, thiab jamming nyob rau hauv tsawg heev kuj (xws li, ntawm nips los yog cov lus qhia). Tsuas yog cov ntaub ntawv uas qhia txog qhov nruj txaus- tau lees paub raws ISO 2493-1-yuav tsum tau muab tso rau hauv cov tshuab luam ntawv electrostatic siab.
5. Cov ntsiab lus noo noo thiab khaws cia
Excess moisture (>6.5% los ntawm qhov hnyav) txo qis hluav taws xob tiv thaiv, cuam tshuam cov txheej txheem electrostatic duab. Cov txiaj ntsig muaj xws li:
a) Nrhav daim ntawv jams-tshwj xeeb yog adhesion rau photoconductor nruas, nres ua haujlwm;
b) faint duab, tsis tshua muaj toner ntom, thiab siab tom qab tsaus;
c) Thermal deformation thaum fusing, ua rau cockling lossis curling.
Txhawm rau txo cov kev pheej hmoo no, khaws cov ntawv hauv huab cua -ib puag ncig tswj (20–25℃, 45–55% RH), kaw kom txog thaum siv. Thaum qhib, rov muab cov khoom tsis siv nyob rau hauv vapor-barrier ntim. Ua ntej- txiav reams (500 nplooj ntawv) yuav tsum tau muab tso rau hauv ntsug hauv daim ntawv lo, cov ntawv tso cua txias-tsis txhob muab tso rau hauv lub tiaj lossis tsis raug rau cov av ib puag ncig.
6. Grain Direction (Fiber Orientation)
Daim ntawv nthuav tawm anisotropic txhua yam khoom raws li nws cov kev coj noj coj ua - lub axis sib npaug mus rau qhov tseem ceeb fiber ntau sib dhos. Rau A3 nplooj ntawv, cov nplej yuav tsum tau ntev (piv txwv li, mus rau qhov ntev ntawm ntug, 420 mm) kom txo qis kev khoov thaum pub mis thiab txo qis kev pheej hmoo. Misaligned nplej nce rau sab buckling thiab impairs rau npe raug, tshwj xeeb tshaj yog nyob rau hauv siab - ntim los yog duplex hom.
7. Chaw thau khoom raws tu qauv thiab kev npaj daim ntawv
Kev thauj khoom kom raug yog qhov tseem ceeb los tiv thaiv misfeeds:
a) Rau ib nrab- voj voog (U-tig) txoj kev pub khoom noj: Muab cov ntawv nrog coated (glossier) sab pem hauv ntej. Rau ncaj- txoj kev (kab rov tav) feeders: Orient lub coated sab upward.
b) Tsis txhob cuam tshuam cov pawg-tsis txhob tso cov ntawv hauv qab ntawm ib pawg ncaj qha rau ntawm daim ntawv sab saum toj ntawm lwm tus hauv tib lub tais.
c) Ua ntej thauj khoom, de- cov nplooj ntawv zoo li qub thiab cais ntawm kev tswj cov kiv cua:
(i) Tuav ib tug ream ntawm ob qho kawg; maj mam twist ib kawg thaum ua kom lwm qhov ruaj khov, tom qab ntawd thim rov qab los ua kom paub txog micro- huab cua khoob;
(ii) Square cov npoo thiab coj mus rhaub kom ruaj khov rau ntawm qhov chaw tiaj tus kom sib haum;
(iii) Maj mam kiv lub pawg kom tshem tawm cov fibers thiab plua plav.
