Npog A5 Spiral Journals Notebooks Dab tsi yog Cov Txheej Txheem Rau Kev Luam Ntawv Xim Luam

Npog A5 Spiral Journals Notebooks Dab tsi yog cov xwm txheej rau luam ntawv xim luam tawm

1, substrate
Substrate yog lub hauv paus ntawm kev luam ntawv xim ci los yog tsis, raws li lub hauv paus ntsiab lus ntawm cov xim luam ntawv, ntxiv rau cov xim ntawm ntau yam xim dot los ntawm kev sib ntxiv ntawm cov xim ntawm qhov chaw sib tov los ua tib neeg lub ntsej muag xim, tsis muaj luam ntawv dot substrate nto. xim. Thiab tau koom nrog hauv qhov sib xyaw ua ke no. Yog li ntawd, yog tias lub substrate whiteness gloss yog siab, koj tuaj yeem txhim kho qhov ci ntawm cov xim. Ntawm qhov tsis sib xws, grey substrate zoo li ntxiv me me ntawm cov xim dub rau ntau yam xim ntawm tus cwj mem, yog li qhia cov xim tsaus. Tsis tas li ntawd, qhov nqus me me ntawm lub substrate yuav cuam tshuam qhov saturation ntawm cov xim. Absorptive substrate, imprinting tsis tuaj yeem tsim kom txaus plump number case txheej ntawm qhov chaw, cov khoom sib txuas ntau dhau mus rau hauv lub substrate ua kom imprinting withered. Daim ntawv nrog cov pores loj yuav ua rau qee cov pigments infiltrate rau hauv daim ntawv ua ke nrog cov khoom sib txuas, kom cov xim saturation txo, cuam tshuam rau qhov ci xim.

2. Ink

Cov yam ntxwv xim ntawm peb tus cwj pwm thawj xim ncaj qha cuam tshuam rau qib ntawm cov xim xim xim, sib txawv ntawm peb hom xim xim xim, nws cov xim tsis zoo, qib grey thiab kev ua haujlwm sib txawv, yog li qhov ci xim ntawm tus number case xim txawv, yog li ntawd, luam ntawv cov khoom zoo, yuav tsum tau siv nrog cov chaw tsim khoom ntawm tib cov qauv ntawm cov xim ci ci. Tsis tas li ntawd, nyob rau hauv cov txheej txheem luam ntawv, sim tsis txhob ntxiv cov neeg ua hauj lwm pab ntau dhau rau hauv cov cwj mem qhuav, kom tus number case emulsification lossis saturation txo. Thaum hloov xim, yog tias tus number case qub tsis tau ntxuav, cov xim tsis zoo ntawm tus number case tom kawg yuav nce thiab qib grey yuav txhim kho, yog li cuam tshuam rau cov xim luam tawm ntawm cov ntawv luam tawm.

3, phaj khoom

Dej offset luam ntawv siv cov khoom siv phaj feem ntau yog PS version. PS version yog raws li polymer photosensitive txheej, thiab cov ntawv luam tawm yog me ntsis siab dua qhov dawb paug. Qhov hydrophilic feem yog aluminium oxide nyias zaj duab xis. Waterless offset printing yog ib qho tshwj xeeb pre-coated photosensitive offset printing phaj. Qhov seem dawb paug yog ib hom tshuaj pleev xim silicone. Cov duab ib feem yog ib tug me ntsis recessed polymer, thiab nto ntawm lub phaj yog antioxidant. Qhov zoo ntawm PS luam ntawv ncaj qha cuam tshuam rau qhov zoo ntawm cov ntawv luam tawm.

4, number case txheej thickness

Hauv cov txheej txheem luam ntawv tiag tiag, tus number case txheej thickness cuam tshuam rau cov xim luam tawm. Lub thickness ntawm tus number case yog nyias, thiab daim duab yog tsaus thiab npub; Lub thickness ntawm tus number case txheej yog thicker, dot o tus nqi nce, lub suab tsaus yog yooj yim los paste, thiab daim duab yog npub thiab theem tsis meej. Yog li ntawd, tus number case txheej thickness yuav tsum coj mus rau hauv tus account lub kauj ruam ntawm reproduction. Feem ntau hais lus, nyob rau hauv qhov kev pom zoo ntawm daim ntawv pov thawj zoo, tus number case txheej thickness yuav tsum tau kho raws li cov ntaub ntawv pov thawj. Rau cov tshuab monochrome, them nyiaj tshwj xeeb rau thawj xim ntawm cov qauv. Lub thickness ntawm thawj xim number case txheej ncaj qha cuam tshuam cov xim luam ntawm tag nrho cov duab.

5. Tshaj tawm tus nqi

Overprint tus nqi sawv cev rau qhov piv ntawm tus lej ntawm tus lej luam tawm ntawm cov xim dhau los rau tus lej ntawm tus lej luam ncaj qha rau ntawm daim ntawv. Qhov piv yog ib txwm tsawg dua 100%, uas yog hais tias, tus lej ntawm tus lej luam tawm hauv cov xim dhau los yog tsawg dua li tus lej luam tawm ncaj qha rau ntawm daim ntawv.

Tus nqi overprint yuav cuam tshuam cov xim saturation ntawm cov xim thib ob. Lub overprint tus nqi yog loj, tag nrho ntawm cov xim yog loj, xim yog brighter. Rau lub tshuab monochrome, tus nqi luam tawm feem ntau yog siab dua, thiab rau lub tshuab multicolor, tsis tsuas yog cov ntawv luam tawm tsawg, thiab yuav ua rau cov xim ua ntej thiab tom qab cov xim sib xyaw.
