Koj puas paub vim li cas koj siv cov ntawv coated los luam cov ntawv luam tawm?

Daim ntawv Copperplate yog tsim nrog kev tshuaj ntsuam luam ntawv, vim tias cov ntawv tsis sib xws ntawm cov ntawv tsis sib xws ntawm qhov tsis sib xws thiab qib ntau dua li txoj kab uas hla ntawm cov dot loj dua, qee cov dots tshwm sim nyob rau hauv qhov sib txawv ntawm cov fibers thiab tsis tuaj yeem hloov tus cwj mem mus rau qhov chaw. daim ntawv, kom cov duab pixel hauv qhov no tsis tuaj yeem tsim dua tshiab.Daim ntawv coated nrog pulp thiab ces calendered, qhov saum npoo ntawm daim ntawv hais me dua lub cheeb ntawm lub dot, lub pulp kuj zoo dua li cellulose fibers, yog li ntawd lub dot yuav raug reproduced.Obviously, coated coated coated ntawv luam ntawv kev ua tau zoo yog zoo dua uncoated offset ntawv.

Cov ntawv qub ntawm cov ntawv coated yog ua los ntawm cov ntawv xov xwm zoo tshaj plaws los yog offset luam ntawv, thiab cov ntawv qib siab coated yog ua los ntawm cov ntawv tshwj xeeb.Cov txheej txheej saum npoo yog ruaj khov rau ntawm daim ntawv qub.Daim ntawv saum npoo yog ces super calendered, nrog ib tug ruaj khov txheej, tsis muaj npuas, tsis muaj streaks, muaj zog gloss thiab siab smoothness.Qhov smoothness ntawm daim ntawv coated feem ntau yog siab tshaj 600s, uas yog ntau tshaj 10 npaug tshaj li ntawm offset ntawv.Qhov no ua rau cov ntawv coated tuaj yeem nyob ze rau ntawm daim ntawv luam ntawv thiab luam tawm cov ntsiab lus kom meej.Tus nqi pH ntawm cov ntawv coated yog nyob ib ncig ntawm 7, uas tsis muaj kev cuam tshuam rau cov tshuaj lithographic ntub dej thiab tsis muaj kev cuam tshuam rau cov txheej txheem kom qhuav.Nyob rau hauv daim ntawv tooj liab daim ntawv number case adheres sai sai, qhuav sai, thiab tom qab ziab kuj tuaj yeem teem lub gloss, zoo reproducibility ntawm lub network point, tus number case txheej yog nyias thiab meej duab, lub network yog huv si.Qhov kev ruaj ntseg ntawm daim ntawv coated kuj zoo dua li cov ntawv offset, thiab luam ntawv ntawm cov ntawv coated tuaj yeem ua tau raws li qhov yuav tsum tau ua kom raug overprinting.Lub zog tensile thiab lub zog saum npoo ntawm daim ntawv coated kuj yog siab txaus los tiv thaiv lub zog tensile ntau dua uas tsim los ntawm cov kua nplaum nplaum ntau dua.Vim yog cov saum toj no, cov ntawv coated feem ntau yog siv los luam cov ntaub ntawv qib siab
