Amandla Okunemba: Ukuhlola Izikrini Zomshini Wokuphrinta

Isingeniso:

Esikhathini sedijithali, imishini yokunyathelisa isiphenduke amathuluzi abalulekile ezimbonini ezihlukahlukene kusukela kokushicilela nokukhangisa kuya ekupakisheni nezindwangu. Le mishini iye yashintsha indlela esiphrinta ngayo, yanikeza ukunemba okungenakuqhathaniswa nokusebenza kahle. Umgogodla wale mishini yokunyathelisa usezikrinini zabo, ezidlala indima ebalulekile ekuqinisekiseni ukuphrinta kwekhwalithi ephezulu. Ukuthuthuka kobuchwepheshe bokuphrinta kuholele ekuthuthukisweni kwezikrini zemishini yokuphrinta yesimanje, ezinikeza ukuqina okuthuthukisiwe, ukunemba, kanye nokuxazululwa. Kulesi sihloko, singena emandleni okunemba ngokuhlola imininingwane eyinkimbinkimbi yezikrini zemishini yokuphrinta.

Ukuqina Okuthuthukisiwe Nokuphila Kade

Izikrini zomshini wokuphrinta zithuthuke kakhulu, zifaka izinto ezisezingeni eliphezulu nemiklamo ukuthuthukisa ukuqina kwazo nokuphila isikhathi eside. Abakhiqizi bayaqonda ukubaluleka kwezikrini ezingamelana nokuguga okuqhubekayo okubangelwa inqubo yokuphrinta. Lezi zikrini zivame ukuchayeka emazingeni okushisa aphezulu, ukucindezelwa komshini, nokusebenzisana kwamakhemikhali ngoyinki nezincibilikisi.

Enye yezinto ezisetshenziswa kakhulu ekwenzeni isikrini insimbi engagqwali. Izikrini zensimbi engagqwali zinokumelana okukhethekile nokugqwala, okuzenza zilungele izindawo lapho ukuchayeka kumakhemikhali nokuswakama kungenakugwema. Angakwazi ukumelana nezimo ezinzima embonini yokunyathelisa, okuvumela ukusetshenziswa isikhathi eside ngaphandle kokuphazamisa ikhwalithi yokuphrinta.

Ngaphezu kwalokho, abakhiqizi baphinde baphendukela ezintweni zokwenziwa ezifana ne-polyester ne-nylon ukuze kukhiqizwe isikrini. Lezi zinto zinikeza inhlanganisela eyingqayizivele yokuguquguquka namandla, ukuqinisekisa ukuthi izikrini zingakwazi ukubekezelela ukusetshenziswa okuphindaphindiwe. Izikrini ze-polyester nezenayiloni azijwayele ukungqubuzana, okuvumela imiphumela yokuphrinta engashintshi esikhathini eside.

Ukunemba ku-Screen Mesh ne-Weave

Ukuthwebula imininingwane eyinkimbinkimbi kanye nokuletha ikhwalithi yokuphrinta ehlukile kuncike kakhulu ekunembeni kwe-mesh yesikrini nokuluka. I-screen mesh ibhekisela enanini lezintambo nge-intshi ngayinye (TPI) futhi ithinta ukulungiswa nokucaca kwesithombe esiphrintiwe. Uma iphezulu i-TPI, i-mesh iba yincanyana, okuholela ekuphrinteni okunembe kakhudlwana anokulungiswa okuphezulu.

Abakhiqizi basebenzisa imishini ethuthukisiwe ukuze bathole inani elifanayo nele-mesh elingashintshi kuso sonke isikrini. Lokhu kuqinisekisa ukuthi ichashazi ngalinye esithombeni lidluliselwa ngokunembile ku-substrate yokuphrinta, okuqinisekisa imigqa ebukhali nemibala egqamile. Ukunemba kuma-mesh esikrini kuqeda ukungahambisani futhi kuqinisekisa ukuthi amaphrinti ahlangabezana nokucaciswa okufunayo.

Iphethini yokuluka yesikrini nayo idlala indima ebalulekile ekuzuzeni ukunemba okukhulu. Amaphethini wokuluka avamile ahlanganisa ama-plain, twill, nama-Dutch weave, ngayinye ihlinzeka ngezici ezihlukile. Izikrini ze-Plain weave zaziwa ngobulula bazo kanye nokuguquguquka, okuzenza zifanelekele izinhlelo zokusebenza ezihlukahlukene zokuphrinta. Izikrini ze-Twill weave zincanyelwa kumaphrinti anokulungiswa okuphezulu, njengoba zihlinzeka ngephethini yokuluka eqinile. Izikrini ze-Dutch weave, ezinokwakhiwa kwazo okuqinile, zilungele izinhlelo zokusebenza ezidinga ukuqina okukhethekile nokumelana nokugqoka.

Intuthuko Ekuxazululeni Nokunemba

Imboni yokunyathelisa ithuthuka ngokuqhubekayo, idinga amazinga aphezulu okulungiswa nokunemba. Abakhiqizi bafinyelele inselele ngokusebenzisa amasu amasha ukuze baqinisekise ukuthi izikrini zabo zihlangabezana nalezi zidingo eziqinile. Ukuthuthuka kwezikrini zemishini yokuphrinta kuholele ekuthuthukisweni kwezikrini ezinezibalo eziphezulu ze-mesh kanye nokunemba kokubekwa kwamachashazi okuthuthukisiwe.

Izikrini ze-Ultra-fine ezinezibalo ze-mesh ezingaphezu kuka-350 TPI seziphenduke insakavukela embonini. Lezi zikrini zinika amandla ukuphrinta kwemininingwane yamaminithi ngokunemba okungenakuqhathaniswa, okuholela ezithombeni ezibukhali nezichaziwe. Uma unemeshi yesikrini incinyane, amachashazi engeziwe ayintshi ngayinye (DPI) angadluliswa, okuvumela amaphrinti anokulungiswa okuphezulu abonisa amaphethini ayinkimbinkimbi, ukwakheka, nokufiphaza.

Ukubekwa kwamachashazi okunembile kubalulekile ekuzuzeni amaphrinti angokoqobo anemibala enembile namagradient. Izikrini zemishini yokuphrinta manje zifaka amasistimu okubhalisa athuthukile aqinisekisa ukuqondana okunembile kwemibala nezinto. Lokhu kuqeda noma yikuphi ukubhaliswa okungalungile noma ukugqagqana okungenzeka phakathi nenqubo yokuphrinta, okuholela kumaphrinti angenasici ahlangabezana namazinga aphezulu ekhwalithi.

Ukulawulwa Kwe-Ink Okuthuthukisiwe Nokufanayo

Esinye isici lapho izikrini zemishini yokunyathelisa zibonise amandla azo okunemba kusekulawuleni uyinki nokufana. Ukuzuza ukugeleza nokusabalalisa kukayinki okungaguquki kubalulekile ekuqinisekiseni ukumbozwa, ukuvimbela ukuhlukahluka kwemibala, kanye nokunciphisa ukumoshwa kwe-inki.

Abakhiqizi bethule ama-coatings akhethekile ebusweni bezikrini zomshini wokuphrinta ukuze bathuthukise ukulawula kukayinki. Lezi zimbotshana zenza kube lula ukunamathela kukayinki kanye nezici zokukhulula, okuqinisekisa ukudluliselwa kukayinki okubushelelezi nokunembayo ku-substrate yokuphrinta. Ukulawulwa kwe-inki okuthuthukisiwe kubangela imibala egqamile, imiphetho ebukhali, nokukhiqizwa kabusha okunembile kwemiklamo eyinkimbinkimbi.

Ngaphezu kwalokho, ukufana kokufakwa kukayinki kube ngcono kakhulu ngenxa yentuthuko yamasu okukhiqiza izikrini. Izikrini ezinokucindezela okulawulwa ngokunembile kanye nezindawo ezisezingeni zivumela ukugeleza kukayinki okungaguquki kuso sonke isikrini. Lokhu kufana kuqeda noma yikuphi ukuhlanganisa noma ukumboza okungalingani, okuholela ekuphrinteni okubukekayo okukhangayo abonisa ukuhambisana kombala okukhethekile.

Isiphetho

Izikrini zemishini yokunyathelisa ziye zavela njengomgogodla wobuchwepheshe bokunyathelisa besimanje, okuvumela ukukhiqizwa kwamaphrinta ekhwalithi ephezulu ngokunemba okungenakuqhathaniswa. Ukuthuthuka okuqhubekayo kwesayensi yezinto ezibonakalayo, amaphethini wokuluka, ukuminyana kwe-mesh, ukulungiswa, nokulawulwa kukayinki kuye kwayishintsha kakhulu imboni yokunyathelisa. Abakhiqizi bayaqhubeka nokuphusha imingcele, bevumela amabhizinisi ukuthi afinyelele imininingwane eyinkimbinkimbi, imibala egqamile, kanye nokwenza kabusha okunembile kumaphrinti awo. Kungakhathaliseki ukuthi okokufaka, izindwangu, noma izinto zokukhangisa, amandla okunemba anikezwa izikrini zemishini yokunyathelisa abumba indlela esibona ngayo futhi siyazisa umhlaba wokuphrinta.
