Amakuru n'Itangazamakuru

Irangi ryerekana neza itandukaniro, ibara, ubwumvikane bwishusho kubintu byacapwe, bityo bigira uruhare runini mugucapa.Hamwe niterambere ryikoranabuhanga, ubwoko bwa wino buragenda bwiyongera, ibikurikira bizashyirwa muburyo ukurikije uburyo bwo gucapa kugirango ubone.

1、Kureka wino

Irangi rya Offset ni ubwoko bwa wino yijimye kandi yuzuye, ibyinshi muri byo ni okiside conjunctiva yumye wino, ifite amazi meza.Irashobora kugabanwa mumpapuro yagaburiwe na wino y'urubuga.Irangi ryagaburiwe impapuro ahanini ni ukumisha vuba okiside ya conjunctiva wino, wino y'urubuga ni iyumisha osose.

2、Inkingi

Nubwoko bwa wino yijimye, viscosity iratandukanye cyane bitewe numuvuduko wo gucapa.Uburyo bwo kumisha burimo gukama osmotic, okisiside ya conjunctiva yumisha, gukama guhindagurika nubundi buryo, cyangwa guhuza inzira nyinshi.Inkingi ya Letterpress ikubiyemo wino yumukara uzunguruka, igitabo cyirabura cyirabura, irangi ryamabara, nibindi.

3、Irangi ryo gucapa

Irashobora kugabanywamo ibyiciro bibiri, kimwe ni wino ya Photogravure, ikindi ni wino intaglio.Irangi rya Photogravure ni amazi yoroheje cyane, ibishishwa biri hasi cyane, byumye rwose na volatilisation ya solvent, ni wino yumisha ihindagurika, irashobora gucapishwa kuri substrate idakurura;Irangi ya intaglio ifite ubukonje bwinshi, agaciro kanini k'umusaruro, nta mavuta, kandi ahanini biterwa no gukama kwa conjunctiva ya okiside.

4、Irangi ryinshi

Irangi ryinshi ryo gucapa risaba amazi meza, ubukonje buke, byihuse binyuze muri meshi, kwimurira hejuru yubutaka bwimitsi irashobora kwihuta kwinjira byumye, byinjira neza mubutaka butagaragara.Uburyo bwo kumisha nuburyo bukurikira: ubwoko bwumuti uhindagurika, ubwoko bwa okiside polymerisation, ubwoko bwa osmotic bwumye, ubwoko bubiri bwibisubizo, ubwoko bwumisha uv, nibindi. Irangi irashobora kugabanywamo wino yanditswemo, wino ya ecran, nibindi.

5、Irangi ryihariye

Irangi ryinshi ridasanzwe rikenera wino yuzuye kugirango ikore neza, irashobora kugabanywamo wino ifuro ifuro, wino ya magnetiki, wino ya fluorescent, wino itwara, nibindi. Igomba kugira ibiranga nta muti uhindagurika, nta mpumuro, nta guhagarika, kwihuta gukira vuba , kurwanya amazi akomeye, ibara ryiza nibindi.

Ibikorwa bya wino biragoye cyane, imiterere yumubiri nayo iratandukanye, bimwe mubyimbye cyane, bimwe bifatanye cyane, bimwe biroroshye cyane, ibi bishingiye kuburyo bwo gucapa, isahani hamwe na substrate kugirango hafatwe ibyemezo byuzuye.
