Wino ikoreshwa mu gucapa ibara ry'amazi yumuka iyo umuntu akoresheje uburyo bufatika, ni ukuvuga mu guhindura imyuka y'ibintu biva mu ruganda, n'inyino y'ibice bibiri binyuze mu gukaraba imiti.
Icapiro rya Gravure ni iki?
Wino ikoreshwa mu gucapa ibara ry'amazi yumuka iyo umuntu akoresheje uburyo bufatika, ni ukuvuga mu guhindura imyuka y'ibintu biva mu ruganda, n'inyino y'ibice bibiri binyuze mu gukaraba imiti.
Ni izihe nyungu n'ibibi byo gucapa gravure?
Ubwiza bwo gucapa buri hejuru
Ingano ya wino ikoreshwa mu gucapa gravure ni nini, amashusho n'inyandiko bifite ishusho y'urukiramende, kandi imiterere yayo irakomeye, imirongo irasobanutse neza, kandi ubwiza bwayo ni bwinshi. Igice kinini cy'icapiro ry'ibitabo, amagazeti, amashusho, gupakira no gushushanya ni ugucapa gravure.
Icapiro ryinshi
Uburyo bwo gukora plaque yo gucapa gravure ni burebure, imikorere ni mike, kandi igiciro ni kinini. Ariko, plaque yo gucapa iraramba, bityo ikaba ikwiriye gucapa mu buryo bwinshi. Uko plaque iba nini, ni ko inyungu iba nyinshi, kandi iyo icapa hakoreshejwe plaque nto, inyungu iba nto. Kubwibyo, uburyo bwo gucapa gravure ntibukwiriye gucapa plaque nto z'ibirango.
(1) Ibyiza: irangi ry'iwino ni hafi 90%, kandi ibara ni ryiza cyane. Irakora neza cyane. Irahangana cyane n'imiterere yayo. Umubare w'ibishushanyo ni munini cyane. Ikoreshwa ry'impapuro zitandukanye, uretse impapuro, naryo rishobora gucapwa.
(2) Ingaruka mbi: ikiguzi cyo gukora amasahani kirahenze, ikiguzi cyo gucapa nacyo kirahenze, akazi ko gukora amasahani karagoye cyane, kandi umubare muto w'amakopi yacapwe ntabwo ukwiriye.
Ibice by'ibanze
Gravure ishobora gukoreshwa mu bikoresho bitandukanye, ariko ikunze gukoreshwa mu gucapa impapuro na pulasitiki byo mu rwego rwo hejuru.
Ishusho y'amacapiro: Imiterere yayo irasukuye, irangana, kandi nta mwanda ugaragara. Amashusho n'inyandiko bishyirwa neza. Ibara ry'icyuma gicapa ni rimwe muri rusange, ikosa ry'ingano y'icapiro rito ntirirenza 0.5mm, icapiro rusange ntirirenza 1.0mm, kandi ikosa ryo gucapa cyane ku mpande z'imbere n'inyuma ntirirenza 1.0mm
Ibibazo Bikunze Kubazwa
Kunanirwa kw'icapiro rya gravure biterwa ahanini n'amasahani yo gucapa, wino, substrates, abakoresha ibyuma bishyushya, n'ibindi.
(1) Ibara ry'ibara ni ryoroheje kandi ntiringana
Impinduka z'ibara ry'iwino zibaho ku bintu byacapwe. Uburyo bwo kubikuraho burimo: gukosora imiterere y'uruziga rw'icyuma gifunga, guhindura inguni n'umuvuduko w'icyuma gifunga cyangwa kugisimbuza ikindi gishya.
(ii) Ishusho irimo ubwoya n'umusemburo
Ishusho y'ikintu cyacapwe irashyirwa mu byiciro kandi ikaranze, kandi impande z'ishusho n'inyandiko bisa n'ibice. Uburyo bwo gukuramo ni: gukuraho amashanyarazi adahinduka ku buso bw'icyuma, kongeramo solvents za polar kuri wino, kongera umuvuduko w'icapiro mu buryo bukwiye, guhindura aho squeegee iherereye, n'ibindi.
3) Ikintu cy’uko wino ifunga yumira mu mwobo w’icyuma gicapa, cyangwa uwo mwobo w’icyuma gicapa wuzuyemo ubwoya bw’impapuro n’ifu y’impapuro, byitwa gufunga icyuma. Uburyo bwo gukuramo ni: kongera ingano y’ibintu bisukura muri wino, kugabanya umuvuduko w’umuvuduko w’icyuma, no gucapa ukoresheje impapuro zifite imbaraga nyinshi.
4) Kwirukana irangi no gushyira amabara ku gice cy'umurima cy'ikintu cyacapwe. Uburyo bwo gukuraho ni: kongeramo amavuta ya wino ikomeye kugira ngo wongere ubukana bwa wino. Hindura inguni y'icyuma gicapa, wongere umuvuduko wo gucapa, simbuza icyuma gicapa cy'umuyoboro muremure ukoresheje icyuma gicapa cy'umuyoboro muremure, nibindi.
5) Ibimenyetso byo gusimbuza: Ibimenyetso by'imashini ikora ku gikoresho cyacapwe. Uburyo bwo gukuraho burimo gucapa wino isukuye nta kintu cy'amahanga cyinjiramo. Hindura ubukana, ubwumye, no gufatana kwa wino. Koresha mashini ikora wino nziza kugira ngo uhindure inguni iri hagati y'imashini ikora wino n'isahani.
6) Imvura y'amabara
Uburyo bwo gukamura ibara ku icapiro. Uburyo bwo gukuraho ni: gucapa wino ifite ikwirakwizwa ryiza kandi ikora neza. Inyongera zirwanya imvura n'izirwanya imvura zongerwa kuri wino. Zingura neza wino kandi uyivange kenshi.
(7) Ihinduka ry'amabara ya wino ku bintu bito bito byacapwe. Uburyo bwo gukuraho ni ubu: guhitamo gucapa wino mu buryo bwihuse, kongera ubushyuhe bw'umuvuduko wo kumisha cyangwa kugabanya umuvuduko wo gucapa mu buryo bukwiye.
(8) Kwirukana wino
Wino yacapwe kuri firime ya pulasitiki ntabwo ifata neza kandi irakurwaho n'intoki cyangwa imbaraga za mashini. Uburyo bwo kuyikuraho ni ubu: gukumira firime ya pulasitiki ku bushuhe, guhitamo gucapa wino neza hamwe na firime ya pulasitiki, kongera gushyira hejuru firime ya pulasitiki, no kunoza ubushyuhe bw'ubuso.
Iterambere rigezweho
Bitewe no kurengera ibidukikije n'impamvu z'ubuzima, inganda zikora ibiryo, imiti, itabi, inzoga n'izindi zirushaho kwita ku kurengera ibidukikije ibikoresho byo gupakira no gucapa, kandi inganda zikora ibicapiro zirushaho kwita ku bidukikije mu mashami yo gucapa. Wino na varnish bita ku bidukikije bizarushaho gukundwa, sisitemu zo gufunga zifunze n'ibikoresho bihindura vuba bizakundwa, kandi imashini zikoresha ibicapiro zikoreshwa mu gupima amazi zizakoreshwa cyane.
