Kev txiav txim siab qhov zoo ntawm daim ntawv kab lis kev cai yuav tsum xav txog tsib yam tseem ceeb: qhov hnyav, xim dawb, smoothness, tensile zog, thiab ib puag ncig ntsuas. Cov kev txwv no feem cuam tshuam rau kev xav, kev pom kev pom, kev luam ntawv, kev ua haujlwm ntev, thiab kev nyab xeeb.
Cov ntsuas no sib sau ua ke "kev ua tau zoo" ntawm daim ntawv; kev txiav txim siab tsis tuaj yeem kos raws li ib qho kev ntsuas. Piv txwv li, lub hauv paus hnyav ≠ zoo. Yog tias kev dawb huv tshaj cov qauv lossis ib puag ncig tsis tau raws li cov qauv, nws yuav ua rau lub qhov muag ua rau muaj kev phom sij. Nov yog cov txheej txheem tshwj xeeb rau kev txiav txim siab zoo:
Qhov hnyav (g / m²): Txiav thickness thiab nruj; nws yog "qhov pib pib."
Muaj nuj nqi: Reflects qhov hnyav ntawm ib cheeb tsam ntawm daim ntawv, ncaj qha cuam tshuam rau thickness, nruj, thiab xav tias tig nplooj ntawv.
High- Cov Qauv Zoo: Txhua Hnub Luam Ntawv / Sau: 70–80 g / m², 80 g yog "golden base weight," tiv thaiv los ntshav-los ntawm thaum lub sij hawm muab ob npaug rau - sab luam ntawv.
Xim Printing / Ntawv Qhia: 100–157 g / m², tuab thiab textured, txhim khu kev pom zoo.
Npog / Daim Npav: 200g / m² lossis siab dua, xws li 250g coated ntawv rau qhov tawv thiab tsis tshua muaj siab-rau-bending cover.
Avoidance Tip: Tsis tshua muaj grammage (<60g) makes it prone to ink bleed-through and tearing; too high a grammage (>300g) tuaj yeem tshaj lub tshuab luam ntawv lub peev xwm.
Dawb (%): cuam tshuam qhov pom kev nplij siab; siab dhau yuav ua mob rau lub qhov muag.
Function: Hais txog daim ntawv lub peev xwm los cuam tshuam lub teeb. Ntau dhau ib tug whiteness yog glaring, thaum tsawg ib tug whiteness ua rau nws dull.
Txuj Txuj Ci:
Rau kev siv txhua hnub, kev ua kom dawb ntawm 80% - 88% yog pom zoo rau nws txoj kev ua siab mos thiab kev tiv thaiv qhov muag, ua tau raws li cov cai ntawm GB / T 30130-2023 rau cov ntawv siv los ntawm cov tub ntxhais kawm theem pib thiab theem nrab.
High whiteness ntawv (Ntau dua los yog sib npaug li 93%) yog haum rau kev tshaj tawm, daim ntawv qhia, thiab lwm yam kev siv uas xav tau cov xim vibrant, tab sis tsis haum rau kev nyeem ntawv ntev.
Avoidance Tip: Paper with a whiteness >90% feem ntau muaj cov tshuaj fluorescent whitening ntau ntau, uas tuaj yeem ua rau pom kev qaug zog tau yooj yim nrog kev siv sijhawm ntev - thiab tej zaum yuav cuam tshuam rau menyuam txoj kev loj hlob ntawm qhov muag.
Smoothness (thib ob): Txiav txim siab kom pom tseeb thiab yog qhov tseem ceeb rau "printability".
Muaj nuj nqi: Ntsuas qhov smoothness ntawm daim ntawv nto, ncaj qha cuam tshuam rau uniformity ntawm number case hloov.
Tus Qauv Zoo: Ntsuas siv txoj kev Bekk; lub sij hawm ntev, qhov siab dua qhov smoothness.
High-quality cultural paper typically has a smoothness >100 vib nas this, ua tiav cov ntsiab lus meej thiab cov xim zoo nkauj hauv kev luam ntawv.
Impact: High smoothness: ntshiab dluab thiab cov ntawv nyeem, cov xim number case, thiab zoo gloss.
Tsawg smoothness: Ua rau muaj teeb meem xws li qhov muag plooj number case, tsis muaj dots, thiab luam ntawv tsis sib xws.
