Nws yog paub zoo tias papermaking yog ib qho ntawm plaub qhov zoo tshaj plaws inventions ntawm Tuam Tshoj thaum ub. Nyob ib ncig ntawm 3,500 xyoo dhau los thaum lub sijhawm Shang Dynasty, Suav cov cim tau kos rau ntawm vaub kib thiab cov pob txha tsiaj, uas yog hu ua pob txha oracle. Nyob rau lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg, xyoob ntoo thiab ntoo strips hloov cov vaub kib thiab cov pob txha tsiaj, thiab hu ua xyoob raj thiab ntoo slips. Ob leeg pob txha oracle thiab xyoob slips tau cumbersome heev. Thaum Lub Sijhawm Tsov Rog Hauv Xeev, tus kws xav Hui Shi nyiam nyeem ntawv thiab ib txwm muaj tsib lub laub uas muaj xyoob slips raws nws thaum nws mus ncig xyuas kev kawm. Yog li, muaj ib lo lus hais tias nws tau kawm raws li tsib lub laub uas muaj phau ntawv. Nyob rau hauv Western Han Dynasty, nyob rau hauv lub tsev hais plaub thiab ntawm cov nom tswv cajceg, txhob lo lo ntxhuav xov los yog paj rwb ntawv yog siv los sau. Thaum sau rau ntawm ib qho ntawm cov ntaub ntawv no, nws yooj yim rau kev sau ntawv, thiab tsis tsuas yog tuaj yeem sau ntau dua li ntawm daim ntawv xyoob thiab cov ntsiav tshuaj ntoo, tab sis kuj tuaj yeem pleev xim rau ntawm lawv. Txawm li cas los xij, nws kim heev thiab tsuas yog siv tau los ntawm ob peb tus tswv cuab ntawm lub tsev hais plaub huab tais thiab nom tswv. Los ntawm lub xyoo pua 2nd BC, daim ntawv twb muaj nyob rau hauv Han Dynasty. Thaum lub sij hawm Eastern Han Dynasty, nws tau rumored tias Cai Lun tau tsim daim ntawv, tab sis qhov tseeb, Cai Lun tsuas yog txhim kho daim ntawv - ua cov txheej txheem. Txawm li cas los xij, archaeologists tau pom cov ntawv ua ntej. Plaub qhov kev tsim khoom zoo tshaj plaws ntawm Tuam Tshoj tau txuas ntxiv mus rau sab hnub poob ua ntej qhov tshwm sim ntawm niaj hnub European kev vam meej. Papermaking tau qhia rau Nyiv los ntawm Kaus Lim Kauslim hauv xyoo pua 7th, thiab rau United Arab Emirates nyob rau nruab nrab- xyoo pua 8. Los ntawm lub xyoo pua 12th, Tebchaws Europe pib xyaum ua cov txheej txheem ntawm Tuam Tshoj thiab teeb tsa cov chaw ua ntawv. Los ntawm lub xyoo pua 16th, ntawv tau dhau los ua neeg nyiam nyob hauv Europe. Kev tsim ntawm daim ntawv tau muab cov txiaj ntsig zoo heev rau kev loj hlob ntawm kev kawm, kev nom kev tswv, thiab kev lag luam hauv Tebchaws Europe thaum lub sijhawm ntawd.
Nyob rau hauv nruab nrab - xyoo pua 19th, cov neeg Askiv thawj zaug tau tsim ib daim ntawv ua txheej txheem. Lawv sib xyaw cov av nplaum dawb thiab nplua porcelain rau hauv ib txheej thiab sib npaug rau saum npoo ntawm daim ntawv qub (ob sab los yog ob sab), yog li tsim cov ntawv zoo tshaj -. Vim tias cov txheej txheem zoo ib yam li tus poj niam siv cov hmoov rau nws lub ntsej muag, nws hu ua hmoov ntawv, uas yog qhov peb hu ua daim ntawv tooj liab. Thawj lub npe Askiv rau daim ntawv tooj liab yog Art Paper, uas yog ib lub npe nrov rau cov khoom lag luam. Qhov tseeb, Art Paper tau muab txhais ua "daim ntawv kos duab" hauv Suav teb xyoo 1930 (ib qho kev txhais ncaj qha). Vim tias thaum daim ntawv no tau siv los luam tawm cov duab zoo nkauj hauv Tebchaws Europe, cov txheej txheem hnub ci ziab siv yog tooj liab corrosion luam ntawv phaj. Yog li ntawd, tom qab lub convention ntawm naming raws li kev siv, daim duab kos duab siv rau copperplate printing yog hu ua copperplate (printing) ntawv. Hauv kev lag luam luam ntawv hauv Suav teb loj, cov npoj yaig hauv cov ntawv ua lag luam txhua tus hu Art Paper "copperplate paper", es tsis yog "cov ntawv hmoov".
Corkboard ntawv, tseem hu ua coated printing ntawv, yog hu ua hmoov ntawv nyob rau hauv cov cheeb tsam xws li Hong Kong. Nws yog qib siab - cov ntawv luam ntawv qib siab ua los ntawm txheej cov ntawv qub nrog xim dawb. Nws yog tsuas yog siv rau kev luam tawm cov npog thiab cov duab kos ntawm qib siab - cov ntawv kawg thiab cov ntawv teev sijhawm, cov duab xim, ntau yam kev lag luam zoo tshaj plaws, cov qauv, cov khoom ntim, cov cim lag luam, thiab lwm yam.
Cia kuv kuj qhia meej tias daim ntawv tooj liab tuaj yeem siv tau hauv cov tshuab luam ntawv inkjet. Muaj cov ntawv tshwj xeeb coated copperplate uas tuaj yeem tso tawm ntawm cov tshuab zoo tib yam, thaum daim ntawv tooj liab tsis tu ncua yuav tsum muaj lub tshuab tshwj xeeb thiab tus cwj mem! Copperplate ntawv kuj tuaj yeem siv rau hauv cov xim hloov xim inkjet luam ntawv (HP DeskJet D2368), tab sis tus nqi luam ntawv tshwj xeeb yog siab heev thiab nws feem ntau tsis pom zoo siv nws. Copperplate ntawv tuaj nyob rau hauv ntau thicknesses: 100, 157, 200, 250, 300, 400, thiab 450 grams. Tam sim no, tag nrho cov no tuaj yeem siv rau hauv cov tshuab luam ntawv inkjet. HP lub tshuab luam ntawv siv thermal npuas tshuab luam ntawv, thiab lub taub hau luam ntawv yog ib qho khoom siv, yog li kev suav nqi yog: nqi=printhead noj + ntawv + number case; EPSON siv micro-electro- tshuab luam ntawv tshuab, thiab cov nqi suav yog: nqi=ntawv + number case. (Cov xim gamut ntawm HP yog qee qhov qis dua rau EPSON. Txawm hais tias HP tau tshaj tawm 12-xim luam ntawv, feem ntau, nws tseem tsis muaj qhov dav xim gamut ntawm EPSON.)
Copperplate ntawv yog ib hom ntawv tiaj tus nrog qhov ntev ntawm 787 × 1092mm lossis 880 × 1230mm thiab lub hauv paus hnyav li ntawm 70 txog 250 grams ib square meter. Daim ntawv tooj liab tuaj yeem muab faib ua ib qho -ib daim ntawv tooj liab, ob npaug- daim ntawv tooj liab, daim ntawv tooj liab matte, thiab daim ntawv zoo nkauj copperplate raws li kev siv sib txawv. Nws kuj tau muab faib ua peb qib: A, B, thiab C raws li qhov zoo. Cov ntaub ntawv tseem ceeb ntawm daim ntawv tooj liab yog tooj liab puag daim ntawv thiab coatings. Copperplate puag ntawv yog tsim los ntawm kev ntaus bleached chemical wood pulp los yog sib tov ntawm ib nrab bleached tshuaj straw pulp ntawm daim ntawv tshuab. Qhov yuav tsum tau ua rau daim ntawv tooj liab yog cov tuab tuab, tsis tshua muaj elasticity, siab zog, thiab dej tsis kam. Daim ntawv saum npoo yuav tsum tsis muaj stains, wrinkles, qhov, thiab lwm yam. Cov txheej uas siv rau daim ntawv thov yog tsim los ntawm cov xim dawb zoo (xws li kaolin, barium sulfate, thiab lwm yam), cov nplaum (xws li polyvinyl cawv, casein, thiab lwm yam), thiab cov khoom siv ntxiv. Cov kua dej no siab heev thiab siab -khoom{20}} cov ntsiab lus txheej yog siv sib npaug thiab nyias los ntawm lub tshuab txheej rau hauv daim ntawv, tom qab ntawd qhuav, dov rau hauv ib lub yob ntawm lub tshuab yob ntawv, xa mus rau super calender rau lamination thiab xov, thiab thaum kawg txiav, xaiv, thiab ntim.
Cov kev cai rau cov ntawv coated muaj xws li cov txheej txheem siab, cov txheej nyias nyias tsis muaj npuas, qhov tsim nyog ntawm cov nplaum rau hauv cov txheej txheem los tiv thaiv cov ntawv hmoov thiab fraying thaum luam ntawv, thiab qhov tsim nyog ntawm xylene los ntawm cov ntawv coated, uas yog tsim rau luam ntawv nrog ib tug mesh suav ntawm 60 kab ib centimeter los yog siab dua.
Copperplate ntawv suav nrog glossy hmoov copperplate ntawv thiab matte hmoov copperplate ntawv. Feem ntau hais lus, matte hmoov ntawv yog hais txog matte hmoov copperplate ntawv, thaum daim ntawv tooj liab feem ntau yog hais txog glossy hmoov copperplate ntawv. Tus nqi luam ntawv ntawm ob yog tib yam. Kev lag luam luam ntawv yuav tsum muaj rau matte hmoov ntawv yog me ntsis siab dua, uas yuav ua rau cov luam ntawv tsaus dhau. Qhov saum npoo ntawm "matte hmoov ntawv" tsis cuam tshuam lub teeb, muaj tus cwj mem zoo nqus, thiab cov ntawv luam ntawv yog tuab, yog li lub sijhawm ziab tom qab luam ntawv yuav tsum ntev dua. Txawm li cas los xij, yog tias qee hom number case yog siv rau kev luam ntawv, qhov teeb meem ntawm lub sij hawm ziab kom qhuav tuaj yeem daws tau tag nrho (cov number case no yog me ntsis kim dua li tus number case).
Feem ntau, siab - cov ntaub ntawv luam tawm zoo yog luam tawm ntawm daim ntawv coated. Coated ntawv tsim nrog rau kev tshuaj ntsuam luam ntawv. Txij li qhov saum npoo ntawm daim ntawv tsis sib xws yog qhov tsis sib xws thiab ntau dua nyob rau hauv qhov siab dua li txoj kab uas hla ntawm cov dots, qee cov dots tau meej nyob rau hauv qhov sib txawv ntawm cov fibers thiab tsis tuaj yeem hloov tus number case rau ntawm daim ntawv, uas ua rau tsis muaj peev xwm rov tsim cov duab pixels ntawm cov chaw no. Tom qab daim ntawv yog coated nrog ib tug slurry thiab ces polished, cov hais nyob rau saum npoo yog me dua lub cheeb ntawm cov dots, thiab cov slurry tus number case nqus cov cuab yeej kuj zoo dua li cov cellulose fibers. Yog li ntawd, cov dots tuaj yeem raug rov tsim dua. Kom meej meej, qhov kev ua tau zoo ntawm kev luam ntawv ntawm cov ntawv coated copperplate yog qhov zoo tshaj ntawm cov ntawv tsis muaj xim offset. Lub hauv paus ntawv ntawm cov ntawv coated copperplate yog ua los ntawm high-rolls zoo ntawm cov ntawv luam tawm los yog offset printing ntawv, thaum high-qib coated tooj liab daim ntawv siv tshwj xeeb hauv paus ntawv. Cov txheej txheej yog ruaj khov rau hauv daim ntawv hauv qab. Daim ntawv saum npoo yog ntxiv super- polished, ua rau cov txheej ruaj khov tsis muaj npuas, streaks, muaj zog gloss, thiab siab smoothness. Lub smoothness ntawm coated copperplate ntawv feem ntau yog siab tshaj 600s, uas yog ntau tshaj 10 npaug tshaj ntawm offset ntawv. Yog li, daim ntawv coated copperplate tuaj yeem tiv tauj lub phaj luam ntawv thiab ua kom pom tseeb ntawm cov dots. Tus nqi pH ntawm coated copperplate ntawv yog nyob ib ncig ntawm 7, uas tsis muaj kev cuam tshuam rau cov dej -raws li number case rau offset printing thiab tsis muaj kev cuam tshuam rau cov txheej txheem ziab ntawm tus number case. Ntawm daim ntawv coated copperplate, tus number case adheres sai sai, dries sai, thiab tseem tuaj yeem cuam tshuam qhov ci tom qab ziab. Kev tsim cov dot yog qhov zoo, cov xim txheej yog nyias thiab cov duab yog qhov tseeb, thiab cov dots yog du. Qhov seem stability ntawm daim ntawv coated copperplate kuj zoo dua li ntawm cov ntawv offset. Thaum luam tawm ntawm daim ntawv coated copperplate, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev sau npe meej. Lub zog tensile thiab lub zog saum npoo ntawm cov ntawv coated copperplate kuj yog siab heev, muaj peev xwm tiv taus qhov nro loj tsim los ntawm cov kua nplaum uas siv tau.
