Thaum ua haujlwm ua ke nrog ntawv tshwj xeeb luam ntawv, txij li hom haujlwm no yog rau kev luam ntawv tshwj xeeb, muaj qee yam yuav tsum tau ua rau luam ntawv tsim. Nov yog cov lus qhia ntxaws txog kev tsim qauv luam ntawv ntawm ntau daim ntawv.
1. Cov ntawv sau
(1) Cov yam ntxwv ntawm daim ntawv embossed
Siv cov tshuab ua kom zoo nkauj lossis cov ntawv tawg, cov qauv sib txuam-convex tau tsim ntawm tus qauv ntawm daim ntawv lossis duab los qhia. Cov ntawv embossed txhim kho nws cov txiaj ntsig kho kom zoo nkauj los ntawm embossing, ua rau cov ntawv ntau dua. Xyoo tsis ntev los no, cov ntawv luam ntawm cov ntawv luam tau nthuav dav thiab nthuav dav. Cov ntawv muaj xim thiab zas xim xws li ntawv offset, ntawv kos duab, daim ntawv ntaj ntaj ntaj, daim ntawv ntaj ntaj ntaj, thiab lwm yam yog embossed (textured) ua ntej luam ntawv, zoo li&"; embossed printing paper &"; qib ntawv, thiab tseem coj tus nqi ntxiv rau qhov muag daim ntawv. Ntau cov ntawv siv hauv cov ntim hloov pauv tau feem ntau yog embossed ua ntej lossis tom qab luam ntawv txhawm rau txhim kho qhov muag pom ntawm lub rooj qhwv thiab txhim kho tus nqi ntawm cov khoom. Yog li ntawd, embossing tau dhau los ua txoj hauv kev tseem ceeb ntawm kev ua ntawv.
(2) Ua cov txheej txheem ntawm cov ntawv embossed
Muaj ob txoj hauv kev los ua cov ntawv embossed. Ib qho yog tias tom qab ntawv tau tsim tawm, tus qauv tau ntxiv rau hauv tshuab los ua cov ntawv embossed; lwm qhov yog tias tom qab daim ntawv tiaj tus ntawv tau qhuav, nws tau muab tso rau hauv lub tshuab embossing rau kev ua tiav ntxiv, thiab tom qab ntawd ob lub thawv ntawv raug nias rau ib leeg, ib qho yog dov lub tog raj kheej nrog cov qauv embossing, thiab daim ntawv yuav tsum tau embossed rau hauv tus qauv thaum daim ntawv yog twisted. Vim tias daim ntawv embossed muaj cov xim zoo nkauj, tsuas yog ib sab ntawm daim ntawv feem ntau yog embossed.
(3) Hom embossing
Embossing tuaj yeem faib ua ob hom: qauv embossing thiab tsis sau npe embossing. Lub npe hu ua embossing yog txhawm rau nias lub paj luam tawm ua lub ntsej muag-convex zoo raws li lub paj paj ntawm kev luam ntawv kom cov cim yuav nce, uas tuaj yeem ua lub luag haujlwm hauv kev kho kom zoo nkauj.
Tsis muaj cov qauv embossing, tus qauv embossed tsis cuam tshuam ncaj qha rau tus qauv ntawm cov ntawv luam. Muaj ntau hom qauv embossed. Xws li cov qauv ntaub, twill qauv, ncaj kab txaij, Yalian net, txiv kab ntxwv tev qauv, ncaj cov qauv, rab koob qauv, qe txheej txheem, lub hnab qauv, qauv qauv, lub lattice qauv, tawv qauv, tawv taub hau qauv, daim ntaub sov lub caij ntuj sov, iav kab txaij, thiab lwm yam Hom no uas tsis yog overprint embossing yog feem ntau siv rau embossing ntawv luam ntawv, coated phau ntawv npog, ntawv patent tawv ntawv, yas hluavtaws ntawv, zaub zaub parchment ntawv thiab lwm yam khoom siv kom zoo nkauj.
Cov ntawv tsim hauv tsev yog ua los ntawm cov ntawv offset thiab cov ntawv ntse. Qhov profile yog ntxhib thiab tsis meej pem, nrog kev ntxhib los mos, nthuav qhia tau zoo, thiab muaj ntau yam sib txawv. Ntau tus kws kos duab xav paub ntau dua hauv kev siv cov ntawv no thiab siv nws los ua cov npog thiab cov npe nplooj ntawv ntawm cov phau ntawv lossis albums los qhia txog tus kheej sib txawv.
2. Cog parchment (ntawv sulfuric acid)
Cov zaub parchment ntawv yog hom ntawv hloov pauv ua los ntawm cov ntoo cog tom qab ntawv tuab tau kho nrog sulfuric acid los hloov cov khoom qub. Nws yog ib nrab pob tshab, daim ntawv muaj ob peb qhov khoob, daim ntawv yog tawv thiab ntom, thiab nws tuaj yeem siv tau, pleev xim, pleev xim rau, lossis xeb. Dhau li, nws yooj yim los sib xyaw nrog cov ntawv taug qab.
Yog li ntawd, ntawv ib nrab pob tshab thiab ntawv sulfuric acid feem ntau siv los ua lub nplhaib hauv qab lossis txheej ntawv rau cov ntawv hauv cov qauv niaj hnub no. Yog tias tau tso cai, lawv tuaj yeem hais tau zoo dua thiab tshem tawm lub ntsiab lus, thiab lawv haum rau cov nthwv dej niaj hnub no. Qee lub sij hawm nws kuj tseem siv ua nplooj ntawv npe ntawm phau ntawv lossis duab duab.
3. Ntawv hluavtaws (ntawv polymer thiab ntawv yas)
Cov ntawv hluavtaws yog ua los ntawm cov khoom siv hluavtaws (xws li PP, PE, PS, thiab lwm yam) raws li cov khoom siv tseem ceeb. Cov tshuaj yaj tau yaj los ntawm qee cov txheej txheem, thiab tom qab ntawd txuas ntxiv thiab txuas ntxiv ua cov yeeb yaj kiab. Tom qab ntawd nws yuav ua tiav rau hauv daim ntawv thiab them nrog cov paj ntoo ntuj. Cov ntaub ntawv tau txais los ntawm qhov ntse, tsis pom kev, thiab luam tawm tau. Feem ntau, cov ntawv hluavtaws tau muab faib ua ob pawg: ib qho yog cov ntawv siv hluavtaws ua hluavtaws, thiab lwm yam yog cov ntawv ua raws cov yeeb yaj kiab.
Sab nraud, daim ntawv hluavtaws tsis txawv ntawm daim ntawv cog ntoo cog ntoo ntuj. Cov yeeb yaj kiab-raws cov ntawv hluavtaws tau nkag mus rau qib high-end ntawv luam ntawv lag luam thiab tuaj yeem hloov kho rau ntau yam ntawm cov tshuab luam ntawv. Cov ntawv hluavtaws uas siv hauv khw tam sim no tsuas yog hais txog cov ntawv ua cov ntawv hluavtaws. Yog tias phau ntawv, tshaj tawm, nqi siv nyiaj, thiab lwm yam luam tawm ntawm cov ntawv hluavtaws tsis raug cim, cov neeg siv nruab nrab yuav tsis tuaj yeem pom qhov sib txawv ntawm lawv thiab cov ntawv nrov.
Cov ntawv hluavtaws muaj qhov ua tau zoo luam ntawv, thiab yuav tsis tsim "GG" "ntawv tawg &"; tshwm sim thaum luam ntawv; tus txheej txheem ntawm cov ntawv hluavtaws pom tias ua pob me me, uas tuaj yeem pab tau zoo hauv kev txhim kho kev tsis pom kev thiab luam tawm tau; cov ntawv hluavtaws cov duab luam tawm tau zoo, Cov dots tau meej, xim xim muag muag, qhov loj ruaj khov, thiab nws tsis yooj yim rau hnub nyoog. Nws tsim nyog sau cia tias thaum siv offset luam ntawv, kev tshaj lij hluavtaws ntawv offset luam ntawv inks yuav tsum siv.
Ntawv tshwj xeeb yog daim ntawv uas siv tshwj xeeb thiab tsim tawm me me. Muaj ntau hom ntawv tshwj xeeb, uas tau sau ua ke los ua ntau yam hom phiaj tshwj xeeb lossis ntawv kos duab. Tam sim no, cov neeg muag khoom xa mus rau cov ntawv kos duab xws li cov ntawv embossed ua cov ntawv tshwj xeeb. Nws yog ib qho tseem ceeb kom yooj yim cov ntsiab lus tsis meej uas tshwm sim los ntawm ntau yam. Muaj ntau hom ntawv tshwj xeeb, thiab cov txiaj ntsig tsim tsis zoo ib yam. Kab lus no luv luv qhia txog kev ceev faj rau kev kos duab ntawv luam ntawv tsim.
