1. I-roller yeyinki
I-ink roller ibhekisela kuzo zonke izintambo ohlelweni lokuhlinzeka ngoyinki. Umsebenzi we-ink roller ukuhambisa uyinki wokunyathelisa epuletini lokunyathelisa ngendlela yobuningi neyokufanayo. I-ink roller ingahlukaniswa ngezigaba ezintathu: ukuthwala uyinki, ukudlulisa uyinki kanye nokuthembela epuletini. I-ink roller ethwala uyinki ibizwa nangokuthi i-ink bucket roller. Isetshenziselwa ukukhipha uyinki wobuningi ebhakedeni leyinki isikhathi ngasinye bese uyidlulisela ku-ink roller edlulisela uyinki (ebizwa nangokuthi i-uniform ink roller). I-ink roller edlulisela uyinki ithola lawa ma-ink futhi iwasabalalise ngokulinganayo ukuze yakhe ifilimu yeyinki efanayo, bese idluliselwa ku-plate backup roller, enesibopho sokusabalalisa uyinki ngokulinganayo epuletini. Kuze kube manje, umsebenzi we-ink roller usuqediwe. Ukusatshalaliswa okufanayo kweyinki kuqedwa kancane kancane enqubweni yokudlulisa elandelanayo yama-cot amaningana. Kule nqubo, ngaphezu kwama-cot, kunezintambo eziqinile kanye nama-roller abizwa ngokuthi ama-ink roller. Ku-offset press, ama-cot kanye nama-hard roll ahlelwa njalo ngezikhathi ezithile, akha i-collocation ethambile neqinile, lokhu kulungiselela kusiza kakhulu ekudlulisweni nasekusabalalisweni kweyinki. Umsebenzi we-inking roller ungaqinisa kakhulu ukusatshalaliswa kwe-axial kwe-inki. Uma isebenza, i-inking roller ingajikeleza futhi ihambe ngendlela ye-axial, ngakho-ke ibizwa ngokuthi i-inking roller.
2. Irola yokudambisa
I-dampening roller iyi-raber roller ohlelweni lokuphakelwa kwamanzi, efana ne-inki roller, futhi umsebenzi wayo ukuhambisa amanzi ngokulinganayo epuletini lokuphrinta. Ama-dampening roller afaka phakathi ukuthwala amanzi, ukudlulisa amanzi, kanye nokuphrinta. Njengamanje, kunezindlela ezimbili zokuphakelwa kwamanzi zama-water rollers, enye yazo ukuphakelwa kwamanzi okuqhubekayo, okuncike ku-plate roller engenaso isembozo se-velvet yamanzi, futhi ukuphakelwa kwamanzi kufezwa ngokulungisa ijubane le-water bucket roller. Indlela yokuqala yokuphakelwa kwamanzi yayingaguquki, eyayincike ku-plate roller embozwe ngesembozo se-velvet yamanzi, kanye ne-water roller egobile ukuze iphakele amanzi. Indlela yokuphakelwa kwamanzi okuqhubekayo ifanele ukuphrinta okusheshayo, futhi indlela yokuphakelwa kwamanzi engaguquki iye yashintshwa kancane kancane.
3. Isakhiwo serola yerabha
I-roll core kanye nezinto zerabha ezisetshenziswa ngaphandle zihlukile kuye ngenhloso.
Isakhiwo se-roller core singaba yimbobo noma siqine kuye ngokuthi sisetshenziswa kanjani. Isisindo se-roller yerabha siyadingeka ngokuvamile, sithinta isisindo esiphikisana nomshini, bese sithinta ukuqina kokudlidliza ngesikhathi sokusebenza.
Iningi lama-roller enjoloba omshini wokunyathelisa we-offset angama-roller angenalutho, ngokuvamile enziwe ngamapayipi ensimbi angewona awe-feng, kanti amakhanda e-shaft ezinhlangothini zombili ahlanganiswe namapayipi ensimbi iyonke. Kodwa-ke, maduze nje, nawo enziwe ngezinto ezingezona ezensimbi, njengepulasitiki eqiniswe ngefayibha yengilazi nezinye izinto ze-polymer, okuhloswe ngazo ukunciphisa isisindo nokuthuthukisa isivinini sokusebenza kanye nokuzinza. Isibonelo, imishini ejikelezayo esheshayo inezibonelo zokusetshenziswa.
4. Izinto zesendlalelo seglue
Izinto zerabha zinomthelela omkhulu ekusebenzeni kanye nekhwalithi yerola yerabha. Izinto zerabha ezahlukene kumele zikhethwe ezindaweni ezahlukene zokusetshenziswa, njengokumelana nokuguguleka, ukumelana nokushisa, ukumelana nokubanda, ukumelana ne-asidi, ukumelana nosawoti, ukumelana namanzi njalo njalo. Kukhona futhi ubulukhuni, ukuthamba, umbala, njll., konke okubekwa phambili ngenxa yendawo yokusetshenziswa kanye nezidingo zamakhasimende.
