Flexo, nk'uko izina ribigaragaza, ni icyuma gicapa gikozwe muri resin n'ibindi bikoresho. Ni ikoranabuhanga ryo gucapa hakoreshejwe inyuguti. Igiciro cyo gukora icyuma kiri hasi cyane ugereranyije n'icyuma gicapa nk'icyuma gicapa cya intaglio. Ubu buryo bwo gucapa bwatanzwe hagati mu kinyejana gishize. Ariko, icyo gihe, ikoranabuhanga rya wino rikoreshwa mu mazi ryari ritaratera imbere cyane, kandi ibisabwa mu kurengera ibidukikije ntabwo byari byitezwe cyane icyo gihe, bityo gucapa ibikoresho bidafata umwuka ntibyigeze bitera imbere.

Nubwo gucapa hakoreshejwe flexographic na gravure muri rusange ari bimwe mu bikorwa, byombi birafunguka, birazunguruka, birahindura irangi, biratuma wino ihinduka, birakama, nibindi, ariko haracyari itandukaniro rinini mu buryo burambuye hagati yabyo. Mu bihe byashize, irangi rishingiye kuri gravure na solvent zigira ingaruka zigaragara zo gucapa. Biruta gucapa hakoreshejwe flexographic, ubu hamwe n'iterambere rikomeye rya wino zishingiye ku mazi, wino za UV n'ubundi buryo bwo kurengera ibidukikije, imiterere y'icapa hakoreshejwe flexographic iratangiye kugaragara, kandi ntabwo ari hasi ya gravure printing. Muri rusange, gucapa hakoreshejwe flexographic bifite ibi bikurikira:

1. Igiciro gito

Igiciro cyo gukora amasahani kiri hasi cyane ugereranyije n'icyo gukoresha gravure, cyane cyane iyo ucapa mu byiciro bito, icyuho ni kinini cyane.

2. Koresha wino nkeya

Icapiro rya flexographic rikoresha plaque ya flexographic, maze wino inyuzwa muri anilox roller, kandi ikoreshwa rya wino rigabanukaho ibirenze 20% ugereranije na plaque ya intaglio.

3. Umuvuduko wo gucapa urihuta kandi imikorere irakomeye

Imashini icapa ikoresheje wino nziza ishingiye ku mazi ishobora kugera ku muvuduko wa metero 400 ku munota, mu gihe icapiro risanzwe rya gravure rishobora kugera kuri metero 150 gusa.

4. Kurushaho kubungabunga ibidukikije

Mu gucapa flexo, inki zishingiye ku mazi, inki za UV n'izindi wino zitangiza ibidukikije muri rusange zikoreshwa, izi winki zitangiza ibidukikije kurusha inki zishingiye ku binyabutabire zikoreshwa mu gushushanya. Nta mvubura ya VOCS iboneka, kandi ishobora kuba iy'ibiryo byo mu rwego rwo hejuru.

Ibiranga imashini zicapa gravure

1. Ikiguzi kinini cyo gukora amasahani

Mu minsi ya mbere, amasahani yo gushushanyaho yakorwaga hakoreshejwe uburyo bwa corruption bwa shimi, ariko ingaruka ntizari nziza. Ubu amasahani ya laser arashobora gukoreshwa, bityo ubwiza buri hejuru, kandi amasahani yo gucapa akozwe mu muringa n'ibindi byuma araramba kurusha amasahani yoroshye yo gushushanyaho, ariko ikiguzi cyo gukora amasahani nacyo kiri hejuru. Ishoramari rinini kandi ryinshi rya mbere.

2. Uburyo bwo gucapa neza no guhuza neza

Icyapa cy'icyuma gicapa ni cyo gikwiriye cyane mu gucapa ku bwinshi, kandi gifite imiterere myiza. Giterwa n'ubushyuhe bwinshi n'igabanuka ryabwo kandi ni gito ugereranyije.

3. Ikoreshwa ry'inkwi nyinshi n'igiciro kinini cyo gukora

Ku bijyanye no kohereza wino, gucapa gravure bikoresha wino nyinshi, ibyo bikaba byongera ikiguzi cyo kuyikora.
