Flexo, nkuko izina ribigaragaza, ni icyapa cyandika cya flexografiya gikozwe muri resin nibindi bikoresho. Nubuhanga bwo gucapa inyuguti. Igiciro cyo gukora amasahani kiri hasi cyane ugereranije nicyapa cyo gucapa ibyuma nka plaque intaglio. Ubu buryo bwo gucapa bwatanzwe hagati yikinyejana gishize. Icyakora, muri kiriya gihe, tekinoroji y’inkunga ishingiye ku mazi yari itaratera imbere cyane, kandi icyo gihe ibisabwa mu kurengera ibidukikije ntabwo byari bihangayikishijwe cyane n’icyo gihe, bityo icapiro ry’ibikoresho bidakurura ntibyatezwa imbere.

Nubwo icapiro rya flexographic hamwe na gravure icapiro ahanini ni kimwe mubikorwa, byombi ntibishaka, guhinduranya, kwimura wino, gukama, nibindi, ariko haracyari itandukaniro rinini muburyo burambuye hagati yabyo. Mubihe byashize, gravure na solvent-ishingiye kuri wino bifite ingaruka zigaragara zo gucapa. Ibyiza kuruta icapiro rya flexografiya, ubu hamwe niterambere ryinshi rya wino ishingiye kumazi, wino ya UV hamwe nubundi buryo bwangiza ibidukikije byangiza ibidukikije, ibiranga icapiro rya flexografiya bitangiye kwigaragaza, kandi ntabwo biri munsi yo gucapa rukuruzi. Muri rusange, icapiro rya flexographic rifite ibintu bikurikira:

1. Igiciro gito

Igiciro cyo gukora amasahani kiri hasi cyane ugereranije na gravure, cyane cyane iyo icapye mubice bito, icyuho ni kinini.

2. Koresha wino nkeya

Icapiro rya flexografiya ryakira isahani ya flexografiya, hanyuma wino ikoherezwa muri roller ya anilox, kandi gukoresha wino bigabanukaho hejuru ya 20% ugereranije na plaque intaglio.

3. Umuvuduko wo gucapa urihuta kandi imikorere irarenze

Imashini icapa flexographic hamwe na wino yo mu rwego rwohejuru y’amazi irashobora kugera ku muvuduko mwinshi wa metero 400 ku munota, mu gihe icapiro risanzwe rishobora kugera kuri metero 150 gusa.

4. Ibidukikije byangiza ibidukikije

Mu icapiro rya flexo, wino ishingiye kumazi, wino ya UV nizindi wino zangiza ibidukikije muri rusange zikoreshwa, zikaba zangiza ibidukikije kuruta wino ishingiye kumashanyarazi ikoreshwa mubikurura. Hafi ya VOCS isohoka, kandi irashobora kuba-ibiryo.

Ibiranga icapiro rya gravure

1. Igiciro kinini cyo gukora amasahani

Mu minsi ya mbere, amasahani ya gravure yakozwe hakoreshejwe uburyo bwo kubora, ariko ingaruka ntabwo zari nziza. Ubu ibyapa bya lazeri birashobora gukoreshwa, kubwibyo bisobanutse neza, kandi ibyapa byo gucapa bikozwe mu muringa n’ibindi byuma biraramba kuruta ibyapa byoroshye, ariko ikiguzi cyo gukora amasahani nacyo kiri hejuru. Ishoramari ryinshi, ryinshi.

2. Gucapa neza neza no guhuzagurika

Isahani yo gucapa icyuma irakwiriye cyane mu icapiro rusange, kandi ifite ihame ryiza. Ihindurwa no kwagura ubushyuhe no kugabanuka kandi ni nto

3. Gukoresha wino nini nigiciro kinini cyo gukora

Kubijyanye no guhererekanya wino, icapiro rya gravure ritwara wino nyinshi, mubyukuri byongera ibiciro byumusaruro.
