1. Omusingi ogukola ogw’ekyuma ekikuba ebitabo ku ssirini .
Okutwala omukono ogukozesebwa ennyo-ekyuma ekikuba ebitabo ekipapajjo ng’ekyokulabirako, enkola ekola ey’ekyuma ekikuba ebitabo ku ssirini esobola okunnyonnyolwa bweti: Amaanyi gayisibwa okuyita mu nkola y’okutambuza, bwe kityo ekisengejja ne kisika yinki n’ekyuma ekikuba ebitabo mu ssirini mu kutambula, olwo ssirini ekyuma ekikuba ebitabo ne ffoomu ya substrate ffoomu. Olw’okuba screen erina tension N1 ne N2, ekola force F2 ku squeegee. Obugumikiriza bufuula ekyuma ekikuba ebifaananyi ku ssirini obutakwatagana na substrate okuggyako layini y’okulowooza. Yinki ekwatagana ne substrate. Wansi w’ekikolwa ky’empalirizo y’okusika F1 ey’okusika, okukuba ebitabo kufuluma okuva ku layini y’embossing etambula okutuuka ku substrate okuyita mu mesh.
Mu nkola y’okukuba ebitabo, pulati y’okukuba ebitabo ku ssirini ne squeegee bitambula nga bikwatagana ne birala, era empalirizo y’okusika F1 n’obugumu F2 nabyo bitambula mu ngeri ya synchronous. Wansi w’ekikolwa ky’okugumira embeera, screen ekomawo mu budde okuva ku substrate okusobola okwewala blot eba encaafu. Kwe kugamba, olutimbe lulema buli kiseera era ne luddamu okusibwa mu nkola y’okukuba ebitabo.
Squeegee eyawulwa ku substrate wamu ne screen printing plate oluvanyuma lw’ekimu-Okukuba ebitabo mu kkubo kuwedde, ate mu kiseera kye kimu, kidda ku yinki okumaliriza cycle y’okukuba ebitabo. Ebanga wakati w’oludda olwa waggulu olwa substrate n’oludda olw’emabega olw’ekyuma ekikuba ebitabo ku ssirini oluvannyuma lwa yinki okuddizibwa luyitibwa ebanga lye limu-olupapula oba ebanga lya ssirini, okutwalira awamu nga lirina okuba mm 2 ku 5. Mu kukuba ebitabo mu ngalo, enkola n’obukugu bw’omukozi bikwata butereevu ku kutondebwa kwa layini y’okulowooza. Mu nkola, abakozi b’okukuba ebitabo ku ssirini bakuŋŋaanyizza obumanyirivu bungi obw’omuwendo, obuyinza okufunzibwa mu nsonga mukaaga, kwe kugamba, okukakasa okugolokofu, okubeera okw’enjawulo, isometric, equalizing, centring and vertical edge in the movement of the squeegee. Mu ngeri endala, olubaawo lwa squeegee lulina okugenda butereevu mu maaso mu kiseera ky’okukuba ebitabo, era terusobola kutambula ku kkono ne ku ddyo; Tekisobola kuba mpola mu maaso n’okusiiba emabega, mpola mu maaso ate mpola mu mugongo oba mu bwangu n’okudduka amangu; Enkoona y’okuserengeta ku bboodi ya yinki erina okusigala nga bweri, era okufaayo okw’enjawulo kulina okussibwako okuvvuunuka enkoona y’okuserengeta ekizibu eky’awamu eky’okweyongera mpolampola; Puleesa y’okukuba ebitabo erina okukuumibwa nga tekwatagana era nga ekwatagana; Ebanga wakati wa squeegee n’enjuyi ez’omunda eza fuleemu ya ssirini lirina okwenkana; Epulati ya yinki erina okuba nga yeesimbye ku fuleemu.
2. Omusingi ogukola ogwa flat screen curved screen printing machine .
Flat screen curved surface screen printing kitegeeza okukuba ebifaananyi ku ssirini nga kiriko ebisenge ebiwanvu (flat screens) ku bitundu ebiriko enkokola ebiringa (cylindrical oba conical curved surfaces). Mu mbeera ezimu, esobola n’okusengejja print ellipse, drum, arc n’ebintu ebirala ebikoonagana. Ekyuma ekikuba ebitabo ekikaluba-NET ekikoona ku ssirini kye kyuma ekikozesa ssirini empanvu okukuba waggulu-n'oludda olukooneddwa olwogeddwako waggulu.
Omusingi ogukola ogw’ekyuma ekikuba ebitabo ku ssirini epapajjo: A-obuwagizi bw’olutindo b-okuwagira enkiiko z’enkiiko c-okuwagira okusimbulizibwa. Mu kiseera ky’okukuba ebitabo, pulati y’okukuba ebitabo ku ssirini n’ebigenda mu substrate bitambula, ate squeegee eyimiridde. Ekyuma ekikuba ebitabo ku ssirini ekipapajjo kinywezebwa ku fuleemu ya ssirini era ekyuma ekikuba ebifaananyi eky’oku ssirini ekikoonagana (flat screen curved screen printing machine) kitambula ku sipiidi etali ya bulijjo, era ekisengejja ekiteekebwa ku kyuma ekiwanirira kikyuka olw’okusikagana kwa ssirini. Sipiidi ya linear ya curved substrate ku impression line y’emu n’embiro ezitambula eza flat screen printing plate okutuuka ku scraping printing.
Mu ndowooza, layini y’okukuba embossing erina okuba ku busbar esinga obunene eya curved substrate okuyamba okwongera ku off-screen angle n’okukakasa omutindo gw’okukuba ebitabo. Okusobola okwanguyiza okutereeza, squeegee okutwalira awamu yeettanira enkoona ey’okungulu eya 60℃±15℃, era kyetaagisa okusobola okutereeza verticality n’ebipimo ebya waggulu n’ebya wansi. Ennongoosereza mu nneekulungirivu kwe kukakasa nti layini y’okusala tekyuka mu bbanga nga etereeza waggulu ne wansi, era bulijjo ekwatagana n’ebbaala ya bbaasi esinga obunene A; Squeegee eriko enkoona ey'okungulu eya 60℃±15℃ekozesebwa okukakasa nti okuserengeta kwa squeegee kukolebwa oluvannyuma lw'okuteekebwa mu nneekulungirivu . Mu nnongoosereza entuufu, okusobola okukakasa nti pulati y’okukuba ebitabo eya ssirini epapajjo eyawulwa okuva ku substrate eriko enkokola mu budde, layini y’okulowooza esobola okuba ey’omulembe katono, naddala nga dayamita ya substrate nnene, layini y’okulowooza erina okukyusibwa mu maaso. Ekyuma ekiwagira okukuba ebitabo mu ngeri ey’okukoona (curved printing) bika eby’enjawulo eby’ebyuma eby’enjawulo bikolebwa era ne bikolebwa abakozesa okusinziira ku byetaago by’ebintu.
Ekintu ekiyitibwa cylindrical container oba conical container kiyinza okukubibwa n’ebibiri bibiri eby’ebizingulula, bbeeri z’emikono ez’ebibikka n’ebikopo ebirina omugerageranyo gw’obuwanvu okutuuka ku dayamita wansi wa 1.5, era ebibya ebigonvu ebigonvu bisobola okuwagirwa ebyuma ebifuuwa omukka. Ellipse eri kumpi kitundu kya ssiringi ku ngulu, ekiyinza okuwagirwa enkola ya cylindrical inlay.
Omusingi gw’okukuba ebitabo ku ngulu kwa kkooni okusinga gwe gumu n’ogw’okukuba ebitabo ku ngulu kwa ssiringi. Enjawulo eri nti ekifaananyi ky’ekyuma ekikuba ebitabo ku ssirini n’engeri y’okutambula kw’ekyuma ekikuba ebitabo ku ssirini. Bw’oba okola ekyuma ekikuba ebitabo ku ssirini okukuba ku ngulu kwa kkooni, sooka osse ekifaananyi ekigaziyiziddwa eky’okungulu kwa kkooni, era ozuule wakati w’ekitundu okusinziira ku kulaba okugaziyiziddwa, n’oluvannyuma londa fuleemu ya ssirini entuufu okukola ekyuma ekikuba ebitabo ku ssirini.
Ku pulati EFGH esobola okubeeramu ddala ffaani-Eri mu nkula ya Abed, pulati y’okukuba ebitabo ekwatagana n’enkula ya ffaani ekolebwa. Teekateeka ku ddyo-omuggo ogw'enkoona ku pulati EFGH, era ogiteeke ne O nga ekisiki okukola pulati esobola okukyusibwa mu ngeri ya ffaani. Olwo, nga okukuba ebitabo ku ngulu kwa ssiringi, ebizingulula 4 bikozesebwa okuwanirira substrate wansi w’ekyuma, squeegee etereezebwa, era fuleemu ya pulati etambuzibwa mu ngeri ya ffaani, era squeegee enyigirizibwa okukuba ku ngulu w’ekyuma ekiyitibwa conical plate. Mu kiseera ky’okukuba ebitabo, bbeeri ya koniki eri mu layini ekwatagana n’ekyuma ekikuba ebitabo ku ssirini wansi wa puleesa emu eya squeegee; Ekipande ky’okukuba ebitabo ku ssirini bwe kitambula mu kifaananyi kya ffaani eky’okwebungulula okwetooloola ekisiki kya ffaani-Okukuba ekifaananyi ekibikkula, ekisengejja kikyuka mu ngeri ey’okukwatagana ku ntambula y’ekyuma ekiwanirira; Yinki enyigirizibwa squeegee n’ekulukuta ku ngulu w’ekisengejja okumaliriza okukuba.
