Muab cov ntawv ntawd tso nyiaj rau 45–50% ntawm tag nrho cov nqi luam tawm-thiab thaum lub sijhawm ua lag luam tsis hloov pauv tsis ntev los no- kev txhim kho tus nqi yuav tsum tau ua kom zoo, cov ntaub ntawv- qhia, thiab hla- koom tes ua haujlwm.
a) Cov Tswv Yim Muag Khoom
- Ua ntej tus nqi-raws li kev xaiv tshaj tus nqi hwm- qib kev yuav khoom: Sib tw daim ntawv qhia meej meej rau txoj haujlwm (xws li, opacity, brightness, caliper) kom tsis txhob dhau - engineering.
- Cov nqi txo nqi, cov nqe lus them nqi zoo (piv txwv li, net-60 vs. upfront), thiab lub caij yuav qhov rais raws caij nyoog raws li cov khoom lag luam kev kwv yees.
- Khaws cov khoom ruaj ntseg rau cov qib txheem; tsuas yog siv -hauv- lub sijhawm xaj rau cov khoom tshwj xeeb hauv substrates kom txo qis kev pheej hmoo ntawm kev laus.
b) Cov khoom siv tuav thiab khaws cia
- Txheeb xyuas hnub tsim khoom raws li tau txais: Cov ntaub ntawv sib zog xav tau ntau dua lossis sib npaug li 30 hnub ntawm kev ua kom zoo dua qub-tsim kom ruaj khov cov dej noo thiab tiv thaiv curling lossis daim ntaub thaiv thaum txiav / pub mis.
- Ua ntej- txiav kev tshuaj ntsuam xyuas qhov tseeb qhov tseeb, grammage zoo ib yam, flatness, thiab xim uniformity; tsis lees txais ntau qhov tsis sib haum tam sim ntawd.
- Protect cut stacks with stretch-wrapping to mitigate hygroscopic deformation; repurpose oversized trimmings (>10-cov ntawv sib npaug) rau kev ua pov thawj, me me - cov haujlwm ua haujlwm, lossis cov ntaub ntawv sab hauv-yielding 3-5% cov khoom txuag txhua xyoo.
c) Pressroom Efficiency Measures
- Qhia cov neeg tsav tsheb kom paub txog daim ntawv- tus cwj pwm tshwj xeeb (piv txwv li, qhov zoo li qub, tus cwj mem nqus tus nqi) thiab kho cov ntawv xov xwm kom haum.
- Siv cov ntawv fij tseg (piv txwv li, tawm- cov ntawv tshwj xeeb lossis cov ntaub ntawv rov qab) thaum lub sij hawm muab daim pam so thiab hloov tus cwj mem kom khaws cia siab - cov khoom muaj nqis.
- Siv lub hauv paus txhua hli- ua rau kev soj ntsuam ntawm daim ntawv- cuam tshuam txog qhov tsis xws luag (piv txwv li, kev sau npe tsis raug, kev xaiv, curl), cov ntaub ntawv tshawb pom hauv cross- kev tshuaj xyuas zoo, thiab ua haujlwm tiv thaiv kev ua haujlwm nrog lub sijhawm lav ris.
