Impamvu yo gutandukanya ibara ryamabara yamabara muburyo bwo gucapa

Mubikorwa byo gucapa, haribintu byinshi bitera umwanya winoki wino ya chromatic asberration, kandi ibyo bintu byaganiriweho bitandukanye hepfo.

Impapuro 1 ku ngaruka zamabara

Ingaruka zimpapuro kuri wino ibara ryerekana cyane muri bitatu.

. Kubwubwoko bumwe bwimpapuro zera, umweru uratandukanye, kandi itandukaniro ryamabara yo gucapa ryibicana ahanini mumwanya wirabura mumwanya wirabura wijimye, kandi ingaruka ziragaragara cyane, kandi ingaruka ziragaragara cyane, kandi ingaruka ziragaragara cyane. Igipimo kiratandukanye cyane. Kubwibyo, mumusaruro nyirizina, impapuro zifite umweru zimwe zigomba gucapirwa uko bishoboka kugabanya ingaruka zuwakaze k'impapuro ku ibara ryacapwe.

. Imiterere yimpapuro igena ko hashyizweho ibitagenda neza n'amakarita byakozwe n'imigozi y'ibimera hejuru yimpapuro. Kugirango ubone uburinganire bwiza nubusanzure bwurupapuro, mubisanzwe ni ngombwa ko utwikira hejuru yimpapuro hamwe nubwinshi bwimigezi itandukanye. Kamere nukabyimba byo gutwikira byerekana ko yinjira hejuru yimpapuro. Hamwe nubushobozi butandukanye bwo kwiyumvisha, birakenewe kugirango amabara yo gucapa ibice bitandukanye. Ugereranije nimpapuro zanditse, NTA -} Igice cyinjira mu mwijima, kijimye, kandi ibara ryivanga, ibara ryivanze rya cyan wino na magenta wino yerekana cyane.

. Ubuso bwimpapuro zo gucapa ni igice -} glossy ubuso, cyane cyane impapuro.

Mu icapiro ryamabara, hafi 4% yumucyo bigaragarira mugihe umucyo uteye hejuru yimpapuro kumpande zabaye 45. Uru ni urumuri rugaragarira hejuru yikibanza cya mbere. Ibisigaye byibyabaye byanyuze kumurongo wino, byatoranijwe na wino, hanyuma bigaragarira binyuze muri wino, kandi bireba ijisho ryumuntu, kandi rifatwa nijisho ryabantu. Iri ni ibara tubona. Niba gloss kandi byoroshye impapuro ari hejuru, urumuri rwagaragaye hejuru yikibanza cya mbere nikintu gishingiye ku myigaragambyo kandi biragoye kwinjira mumaso yabantu. Ibara ryagaragaye muri iki gihe ni ibara ryerekanwe na wino. Niba ubuso bwimpapuro bukabije kandi glikass ni hasi, ibitekerezo bitandukanye bizabera hejuru yikibanza cya mbere. Muri iki gihe, ibara tubona ni uruvange rwumucyo nyamukuru wamabara kandi urumuri rugaragarira hejuru yikibanza cya mbere. Kubera ko hari ikintu cyera cyera imbere, cyuzura urumuri nyamukuru rwamabara rugabanuka. Kubwibyo, iyo abantu bubahirije ibicuruzwa byacapwe, ibara rihinduka, kandi iyo ubucucike bupimwa hamwe nigitambararo gigabanya kandi umurambo uriyongera.

Ingaruka zo kuvura hejuru kumabara

Uburyo bwo kuvura hejuru bwibicuruzwa bipakira ahanini birimo guhimba (filime mbi, firime ya mat), gukinisha (amavuta meza, matt, uv varnish) nibindi. Nyuma yo kuvura hejuru yibicuruzwa byacapwe, hazabaho urugero rwihishe hamwe namabara afite amabara. Izi mpinduka zigabanijwemo impinduka zumubiri nubupfumu. Impinduka zumubiri zigaragarira cyane muburyo bwo gutekereza no kubigaragaza hejuru yibicuruzwa, bifite uruhare runaka kubwubusa. Iyo utwikiriye firime nziza, utwikire amavuta yoroheje na UV, ubucucike bwibara ryiyongera; Iyo utwikiriye firime mat, utwikire amavuta matte, ubucucike bwamabara buragabanuka. Guhindura imiti biva ahanini na firime ya plastike, amavuta ya UV base, hamwe nibiti bitandukanye birimo amavuta ya UV, bizahindura ibara ryicapa.

3 ingaruka zoroheje kumabara

Umukozi ushishikaye ni paste - nkikintu kitagira ibara kandi kibonerana, kirimo cyane cyane kigira uruhare runini mu icapiro ryamabara. Umubare woroheje wongeyeho uratandukanye, kandi ingaruka kuri hue nazo ziratandukanye, cyane cyane ibara ry'ubururu nizo zigaragara cyane.

In the process of formulating spot-color inks, the leveling force and pressure generated by the uniform ink meter and the ink-extracting instrument are smaller than those on the printing press. Nta mpamvu yo kongeramo urumuri mugihe cyo gucapa, ariko koresha gusa koroshya kugirango ukore ikarita imwe yo kwerekana ikarita. Kubireba ubucucike bwamabara, hariho itandukaniro ryamabara hagati yikarita yamabara nibicuruzwa byacapwe. Ibi ni ukubera ko byongeweho umukozi wa dilutit ahindura agabura iyi pigment muri wino kandi bigatera wino gukurura, kurobanuka, no kwerekana urumuri. Nkibisubizo byimpinduka, hariho itandukaniro ryamabara, riterwa nitandukaniro muri sisitemu.

4 Ingaruka z'itandukaniro ryumutsi

Kubicuruzwa byacapwe byacapwe gusa, wino iracyatose kandi ifite itandukaniro ryubucucike iyo bwumye. Ibintu byunvike bike cyane birenze ubucucike bwumutse buvugwa nkubucucike bwumutse. Ni ukubera ko igice cya wino cyacapwe gifite ibintu bimwe na bimwe biringaniye, bityo rero uburyo bwo kwerekana hejuru bwiganjemo ibitekerezo bitandukanye, bisa neza kandi birabagirana. Iyo urwego rwinkingi ari muburyo bwumutse, kwerekana ubuso bwiganjemo ibyoroshye, kandi ibara risanzwe kandi ryijimye kuruta igihe ryacapwe.

Kubera ko ubucucike bwumutse bukoreshwa nyuma yo gucapa iminota 30 kugeza kuri 60 nyuma yo gukama, ibi bivamo ingorane zo gupima no kugenzura ubucucike bwanditseho.

Igidasanzwe hamwe nigikoresho cya polaririzor kirashobora gukuraho urumuri ruva hejuru yikibuga cya wino kubera ubwenge butandukanye kugirango habeho ibara ryumutuku kuburyo butunganijwe neza kandi bwumye. Ku mpapuro zashizweho, itandukaniro ryubusa ryapimwe ni 0.05 kugeza 0.15, na Not Not-}} impapuro zanditse zifite itandukaniro ryuzuye rya 0.1 kugeza 0.2. Itandukaniro ryamabara naryo ritandukanye namabara atandukanye, hamwe nitandukaniro rito ryumuhondo, ibara rinini ryirabura, hamwe namabara yubururu n'umutuku hagati. Kubwibyo, iyo bipimwe hamwe na densitometero nkiyi, agaciro kapimwe kagomba kuba hejuru kuruta agaciro k'ubucucike bw'isanduku isanzwe, kugira ngo dukine inshingano zo kugenzura.

5 Ingaruka za sisitemu itandukaniro

Inzira yo gukora ikarita yamabara hamwe na metero imwe yo muri wino hamwe na wino yerekana "gahunda yumye". Nta mazi arimo, kandi icapiro ni "gahunda yo gucapa". Amazi atose agira uruhare mubikorwa byo gucapa. Kubwibyo, wino igomba gukorerwa mu icapiro rya Offset. The emulsification phenomenon of the water-in-oil emulsified ink changes the distribution state of the pigment particles in the ink layer, and inevitably produces a color difference, and the printed product also appears to be dark in color and not vivid.

Byongeye kandi, gushikama kwa wino bikoreshwa mugukuramo amabara, ubunini bwikinyinge cyinjira, ihuriro rishya kandi rishaje kandi rifite ingaruka zinyuranye nazo zishingiye ku itandukaniro ryamabara. Ingaruka.
