Ma UV (ultraviolet) na EB (electron beam) na-agwọ ọrịa na-eji radieshon electromagnetic, nke dị iche na ọgwụgwọ okpomọkụ IR (infrared). Ọ bụ ezie na UV (Ultra Violet) na EB (Electron Beam) nwere ogologo wavelength dị iche iche, ha abụọ nwere ike ịkpata nchikota kemịkalụ na ink sensitizers, ya bụ, crosslinking elu-molecular crosslinking, na-ebute ọgwụgwọ ozugbo.
N'ụzọ dị iche, ọgwụgwọ IR na-arụ ọrụ site na ikpo ọkụ ink, na-arụpụta ọtụtụ mmetụta:
● Evaporation nke obere ihe mgbaze ma ọ bụ mmiri mmiri,
● Na-eme ka oyi akwa ink dị nro na ịba ụba na-asọpụta, nke na-enye ohere ịnweta na ihicha,
● Ọkịtị oxidation nke elu kpatara site na ikpo ọkụ na kọntaktị na ikuku,
● Ịgwọ resins na mmanụ dị elu n'okpuru okpomọkụ.
Nke a na-eme ka IR gwọọ ọtụtụ akụkụ na usoro ihicha akụkụ, karịa otu usoro ọgwụgwọ zuru oke. Ink ndị na-agbaze mgbaze na-adị iche ọzọ, n'ihi na ọgwụgwọ ha na-enweta 100% site na evaporation ihe mgbaze nke ikuku na-enyere aka.
Ọdịiche dị n'etiti UV na EB Curing
UV ọgwụgwọ dị iche na EB ọgwụgwọ tumadi na penetration omimi. Ụzarị UV nwere oke ntinye; dịka ọmụmaatụ, oyi akwa ink gbara ọkpụrụkpụ 4-5µm chọrọ iji ọkụ ọkụ UV dị elu gwọọ ngwa ngwa.

Ma ọ bụghị ya, elu ahụ nwere ike gwọọ ebe oyi akwa nke dị n'ime na-anọgide na mmiri-dị ka akwa esighị ya - nwere ike ime ka elu ahụ gbazee ma rapara.
Ntinye UV na-adịkwa iche nke ukwuu dabere na agba ink. A na-abanye n'ime ink Magenta na Cyan ngwa ngwa, mana ink Yellow na Black na-enweta ọtụtụ UV, ink ọcha na-egosipụtakwa ọtụtụ UV. Ya mere, usoro nke agba layering na-ebi akwụkwọ na-emetụta nke ukwuu ọgwụgwọ UV. Ọ bụrụ na ink ojii ma ọ bụ odo nwere nnukwu nnabata UV dị n'elu, ink na-acha uhie uhie ma ọ bụ na-acha anụnụ anụnụ nwere ike ịgwọta nke ọma.

N'aka nke ọzọ, ọgwụgwọ EB enweghị ọdịiche dabere na agba na ọgwụgwọ ma nwee ntinye siri ike. Ọ nwere ike banye n'ime akwụkwọ, rọba na ihe ndị ọzọ, na-agwọkwa akụkụ abụọ nke mbipụta n'otu oge.

White underlay ink bụ ihe ịma aka karịsịa maka ọgwụgwọ UV n'ihi na ha na-egosipụta ìhè UV, mana ọgwụgwọ EB adịghị emetụta ya. Nke a bụ otu uru EB nwere karịa UV.
Otú ọ dị, ọgwụgwọ EB na-achọ ka elu dị na gburugburu ikuku oxygen iji nweta ọgwụgwọ zuru oke.
