Urufunguzo rwa gravure wino yo gucapa ubuziranenge: viscosity

Viscosity iterwa nimpamvu nyinshi, zirimo ubwiza bwihariye bwumuti wa binder resin, imitungo ya pigment (nko kwinjiza amavuta, igereranyo, ingano yingingo, no gutatanya), guhuza hagati yibintu na binders, hamwe nubwoko nubunini bwumuti. Icyerekezo kizaza kuri wino ya plastike intaglio nuruvange rwinshi hamwe nubukonje buke.

• Viscosity igira ingaruka zikomeye kumiterere yicapiro: ubukonje bwinshi bugabanya amazi, bikavamo kuzura kutuzuye kwingirangingo cyangwa ibibara byera; ikoresha imbaraga nyinshi ku cyuma cya muganga, itera ingorane zo gusiba no gukata; kandi ibangamira ihererekanyabubasha, biganisha ku guhagarika. Ku rundi ruhande, ubukonje bukabije burenze urugero butera irangi ryinshi, bikagaragaza nk'ibimenyetso by'amazi, bikagabanuka neza, kandi bikaba bishoboka ko ibibazo bya electrostatike byiyongera, bikabuza ibara rimwe.

• Ubwiza bwakazi bwa wino bugomba guhinduka ukurikije umuvuduko wo gucapa nibiranga isahani. Icapiro ryihuse risaba ububobere buke kugirango wohereze neza wino; icyakora, wino yo hasi irashobora guteza imbere ibimenyetso byamazi hejuru yubukonje buke cyane, ntibikwiriye inzira yihuta. Ijwi ryimbitse hamwe n’ahantu hakomeye bisaba irangi ryinshi ryijimye kugirango ryororoke rirambuye, mugihe uturere tworoheje, cyane cyane dufite ibimenyetso byingenzi, twungukirwa na wino yo hasi. Irangi ryujuje ubuziranenge ritanga intera yagutse yimiterere ihindagurika, mugihe abakene bafite intera ndende kandi igarukira kubikorwa byo hejuru cyane.

• Ibintu bigira ingaruka kumikorere ya wino ikubiyemo igipimo cyo kongeramo umusemburo, gukora neza gushonga, ubushyuhe bwibidukikije hamwe na wino, igipimo cyuka cyuka, hamwe nuburinganire bwumuti. Ongeramo ibishishwa bikwiye birashobora guhindura ububobere, ariko kurenza urugero birashobora gukurura inenge; guhuza ibishishwa bitandukanye byongera imbaraga; ihindagurika ry'ubushyuhe rigira ingaruka ku gihe cyo gukama no gukama; guhumeka neza bisaba kuzuzwa mugihe kugirango bikomeze neza; nubusumbane bwumuti bushobora gutera ubukonje budasanzwe cyangwa imvura igwa, bisaba ko hahindurwa ibihimbano kugirango bigarure uburinganire.
