In packaging and trademark printing, the application of pearlescent printing has been very common. It not only gives people the enjoyment of pearl-like luster, but also has a certain anti-counterfeiting function. In addition to the use of pearlescent ink, pearlescent printing also uses pearlescent paper and pearlescent paper. The difference between the two is that pearlescent ink printing is a pearlescent effect in the graphics and text, while pearlescent paper and pearlescent paper printing are printing other than graphics and texts. The object exhibits a pearlescent effect. Since pearl paper and pearl paper printing are different from ordinary paper, film and other printing, it is necessary to pay attention to the correct selection of ink in printing and master printing skills in order to print ideal prints. Let's talk about some issues that need to be paid attention to in the printing of pearl paper and pearl paper.
1. Pearl ntawv luam ntawv
1. Cov yam ntxwv tseem ceeb ntawm cov ntawv hlaws
Cov ntawv muaj pes tsawg leeg ntawm pearl ntawv yog tib yam li cov ntawv dawb dawb, uas yog, nws muaj peb ntu: hauv qab fiber ntau, muab tub lim thiab txheej txheej. Qhov sib txawv ntawm cov ntawv dawb dawb yog qhov txheej txheej ntawm cov ntawv hlaws muaj cov khoom uas tsim cov nyhuv pearl. Cov khoom yog tsim los ntawm titanium oxide (los yog lwm yam hlau oxides) thiab mica flakes, thiab cov mica flakes yog qhwv los ntawm titanium dioxide los yog lwm yam hlau oxides los ua ib tug flakes -zoo li cov qauv. Feem ntau hais lus, pearl ntawv muaj ob yam ntxwv.
(1) The surface energy is low, and the adsorption performance of ink is poor. Because the surface of the sheet structure composed of mica and titanium dioxide or other metal oxides is relatively smooth, and the paper surface is required to be relatively smooth in the papermaking process, so that the paper has a better pearlescent effect and satisfies people's visual enjoyment, but this makes pearlescent paper. The surface energy of the paper is much smaller than that of ordinary whiteboard paper, so that the ink is not easy to adhere and absorb, and it is not easy to dry during printing.
(2) Cov nyhuv pearlescent rau saum npoo yog yooj yim puas. Txij li daim ntawv qauv tsim los ntawm mica thiab titanium dioxide los yog lwm yam hlau oxides cuam tshuam los ntawm lub siab thiab dabtsi yog khoov thaum lub sij hawm luam ntawv, nws yog ib qho yooj yim mus ua txhaum cov pearlescent ntawv, los yog nws yog detached los ntawm daim ntawv vim viscosity ntawm tus number case thaum luam ntawv. . Thaum lub sij hawm tus txheej txheem, nws yog ib qho yooj yim mus poob lub pearlescent nyhuv thiab nthuav tawm hauv qab ntawm daim ntawv los ua cov pob dawb.
2. Cov teeb meem xav tau kev saib xyuas hauv pearl ntawv luam ntawv
Hauv kev xav, kev luam ntawv ntawm pearl ntawv tuaj yeem siv offset printing, gravure printing, flexographic printing, screen printing thiab lwm yam luam ntawv, tab sis raws li kev xyaum ua, nws yog tsim nyog los siv offset printing. Vim tias cov khoom pearlescent ntawm cov ntawv pearlescent tau tawg yooj yim, thiab cov khoom ib nrab -cov khoom tiav tsis tuaj yeem tiv taus qhov sib txuas thiab kev sib txhuam, cov txheej txheem tsim khoom yuav tsum luv luv li sai tau, thiab qee qhov kev sib txuas ntawm cov txheej txheem yuav tsum raug tshem tawm, tshwj xeeb tshaj yog cov uas muaj kev koom tes ntau dua. Cov uas tuaj yeem luam tawm ib zaug tsis tas yuav tsum luam tawm ob zaug, cov uas tuaj yeem luam tawm los ntawm kev luam ntawv offset tsis tas yuav tsum tau tshuaj ntsuam luam tawm, cov uas tuaj yeem ua kua roj vanish ntawm lub tshuab tsis tas yuav varnished offline, thiab Ntawm cov hoob kawm, cov uas tsis tuaj yeem varnished yog resolutely tsis varnished, vim varnishing kuj zoo heev tsis muaj zog ntawm pearl ntawv. pearl nyhuv. Txij li cov ntawv hlaws feem ntau qhia txog cov txiaj ntsig zoo ntawm daim ntawv hlaws, yog tias qhov chaw luam ntawv loj dhau, qhov npog ntawm tus number case yuav loj dua. Vim lub shading thiab opacity ntawm tus number case, lub pearl nyhuv ntawm daim ntawv yuav tsis muaj zog heev thaum nws dhau los ntawm tus number case txheej. , yog li ntawd cov nyhuv pearl ntawm daim ntawv tsis tuaj yeem cuam tshuam. Yog li ntawd, peb yuav tsum sim kom tsis txhob loj - cheeb tsam cov qauv luam ntawv raws li cov yam ntxwv ntawm pearl ntawv thaum tsim phaj. Feem ntau, qee cov qauv kab yooj yim, cov ntawv nyeem, thiab lwm yam yog tsim, uas tuaj yeem tsis tsuas yog hais txog cov ntsiab lus tseem ceeb ntawm cov ntsiab lus ntim, tab sis kuj qhia tau cov txiaj ntsig zoo nkauj hlaws ntawm daim ntawv.
Rau kev xaiv pearl ntawv luam ntawv number case, feem ntau muaj peb hom inks: UV number case, tsis yog -absorbent ntawv luam ntawv number case thiab tus number case zoo tib yam, uas tuaj yeem siv rau luam ntawv hlaws ntawv, tab sis cov nyhuv luam ntawv ntawm txawv inks kuj txawv. Ink, phem tshaj yog tus cwj mem zoo tib yam.
(1) UV number case luam ntawv. UV number case luam ntawv siv ultraviolet ziab, thiab txhua chav luam ntawv tau nruab nrog lub tshuab ziab khaub ncaws ultraviolet thaum luam ntawv. Thaum UV number case dhau los ntawm lub tshuab ziab khaub ncaws, lub sij hawm ziab yog luv luv nyob rau hauv qhov pib ntawm photoinitiating pab pawg neeg, uas tuaj yeem hais tau kom qhuav tam sim ntawd, yog li cov ntawv luam tawm tau qhuav tag thaum nkag mus rau chav luam ntawv tom ntej los yog txais link. Cov txheej txheem xws li nce tus lej ntawm tus lej tuaj yeem siv los txhim kho tus lej ntawm tus lej ntawm tus lej ntawm daim ntawv hlaws. Nyob rau tib lub sijhawm, kev luam tawm ntawm tus cwj mem kuj tseem yog ib qho qhuav - nias- qhuav overprinting txoj kev, uas tuaj yeem txhim kho tus nqi ntau dua. Yog li ntawd, UV number case luam ntawv feem ntau tsis muaj teeb meem los ntawm ziab, tiv thaiv - nplaum, thiab hmoov poob los ntawm pearl ntawv; Nyob rau tib lub sijhawm, UV number case luam ntawv yuav tsis tsim khawb, cov kua nplaum ntawm daim tawv nqaij thiab lwm yam tshwm sim. Tsis tas li ntawd, UV number case yog ib puag ncig tus phooj ywg tus cwj pwm uas tam sim no tau nce qib.
(2) Tus cwj mem tshwj xeeb luam ntawv rau tsis yog - ntawv luam ntawv. Nws hais txog tus cwj mem tshwj xeeb tshwj xeeb uas siv rau kev luam ntawv nrog ntau yam tsis yog -absorbent nto, xws li JP number case ntawm Hangzhou Hanghua. Cov inks no tshwj xeeb rau cov ntaub ntawv uas tsis tshua muaj zog saum npoo thiab cov khoom nqus dej tsis zoo. Cov txheej txheem luam ntawv yog tib yam li kev luam ntawv zoo tib yam, uas tuaj yeem txhim kho qhov adhesion thiab ziab kom zoo ntawm cov ntawv luam ntawv txheej, tab sis cov luam ntawv ceev yuav tsum tsis txhob nrawm dhau los tiv thaiv tus number case los ntawm kev lig dhau lawm kom qhuav thiab ua rau sab nraub qaum. ua qias neeg.
(3) Ordinary number case printing. Rau pearl ntawv luam ntawv cov khoom uas tsis zoo yuav tsum tau thiab batch me me, feem ntau cov tuam txhab uas muag siv tus cwj mem zoo tib yam los luam, uas yuav tsis tau tsuas yog ua tau raws li cov kev cai ntawm cov neeg muas zaub, tab sis kuj yuav economical.
Ib qho ntxiv, cov teeb meem hauv qab no feem ntau tshwm sim hauv Pearl Ntawv luam ntawv, poob me me kom qhuav, yooj yim muab tso rau ntawm sab nraum qab, yooj yim rau kos, thiab lwm yam; pearl nyhuv yog ib qho yooj yim los plam, yooj yim luam tawm Qhov tsim ntawm cov pob dawb, paj, creases thiab lwm yam tshwm sim yog txhua yam uas yuav tsum tau them sai sai rau hauv pearl ntawv luam ntawv.
