Incazelo yenqubo yokuphrinta isikrini sendebe

Ilogo inyatheliswa kanjani ku-indebeZingaki izindlela? Njengamanje, indlela yokuphrinta ilogo nephethini enkomishini incike esimweni esithile.

Okulandelayo kuchaza inqubo yokuphrinta isikrini sendebe ejwayelekile emakethe:

Ukuphrinta kwesikrini kuwukwelula indwangu kasilika, indwangu yefayibha yokwenziwa noma i-mesh yensimbi ohlakeni lwesikrini, bese wenza ipuleti lokuphrinta kwesikrini ngokuqopha ngesandla ifilimu yopende noma ukwenza ipuleti le-photochemical. Ubuchwepheshe besimanje bokuphrinta kwesikrini busebenzisa izinto ezithinta ukukhanya ukwenza amapuleti okuphrinta kwesikrini ngokwenza ipuleti lezithombe.

Indlela yokwenza amapuleti:

Indlela yokwenza ipuleti ngqo iwukuqala ngokubeka isisekelo sefilimu yesihlakala esimbozwe ngezinto ezithinta ukukhanya etafuleni lokusebenza ifilimu ethinta ukukhanya ibheke phezulu, ubeke uhlaka lwe-wrist mesh olululiwe phansi esisekelweni sefilimu, bese ubeka i-slurry ethinta ukukhanya ohlakeni lwe-mesh bese ulufaka ngaphansi kwengcindezi ngesikrufu esithambile, ususe isisekelo sefilimu yepulasitiki ngemva kokoma ngokwanele, bese unamathisela i-wrist mesh yefilimu ethinta ukukhanya kuyo ukuze kunyatheliswe ipuleti, engasetshenziswa ngemva kokuthuthukiswa. Ngemva kokomiswa, kwenziwa ukuphrinta kwesikrini sesilika.

Ukugeleza kwenqubo:

i-Net enwetshiwe – ukususa amafutha – ukomisa – ukususa isisekelo sefilimu – ukuvezwa – Intuthuko – ukomisa – Ukubuyekezwa – ukuvalwa kwesikrini

isimiso sokusebenza:

Ukuphrinta kwesikrini kuqukethe izinto ezinhlanu: ipuleti lokuphrinta kwesikrini, i-scraper yokuklwebha, uyinki, ithebula lokuphrinta kanye ne-substrate.

Isimiso esiyisisekelo sokuphrinta isikrini ukusebenzisa isimiso esiyisisekelo sokuthi i-mesh yengxenye yesithombe sepuleti lokuphrinta isikrini ingangena ngoyinki kanti i-mesh yengxenye engeyona i-graphic ingangeni ngoyinki.

Uma uphrinta, thela uyinki kolunye uhlangothi lwepuleti lokuphrinta isikrini, ufake ingcindezi ethile engxenyeni yeyinki yepuleti lokuphrinta isikrini ngesikrufu sokuklwebha, bese udlulela kolunye uhlangothi lwepuleti lokuphrinta isikrini ngesikhathi esifanayo. Uyinki ucindezelwa kusukela ku-mesh yengxenye yesithombe kuya ku-substrate yi-scraper ngesikhathi sokunyakaza. Ngenxa ye-viscosity yeyinki, uphawu luqiniswa ngaphakathi kobubanzi obuthile. Ngesikhathi senqubo yokuphrinta, isikrufu sihlala sixhumene nepuleti lokuphrinta isikrini kanye ne-substrate, futhi umugqa wokuxhumana uhamba nokunyakaza kwesikrufu. Ngenxa yesikhala esithile phakathi kwepuleti lokuphrinta isikrini kanye ne-substrate, ipuleti lokuphrinta isikrini likhiqiza amandla okusabela kusikrufu ngokusebenzisa ukucindezeleka kwalo, Lokhu kusabela kubizwa ngokuthi ukuqina. Ngenxa yendima yokuqina, ipuleti lokuphrinta isikrini kanye ne-substrate kuxhumene kuphela nomugqa weselula, kuyilapho ezinye izingxenye zepuleti lokuphrinta isikrini zihlukaniswe ne-substrate. Yenza uyinki nesikrini ziqhekeke, qinisekisa ukunemba kobukhulu bokuphrinta futhi ugweme ukuhlikihla i-substrate. Uma i-scraper iklwebha yonke indlela, iyaphakama, futhi ipuleti lokuphrinta isikrini nalo liyaphakama, bese liklwebha ngobumnene uyinki libuyele endaweni yalo yokuqala. Lolu uhambo lokuphrinta.

Izinzuzo zokuphrinta isikrini:

(1) Akukhawulelwe ngobukhulu kanye nesimo se-substrate

Ukuphrinta kwesikrini akugcini nje ngokuphrinta endaweni, kodwa futhi nokuphrinta entweni ebunjiwe enesimo esikhethekile, njengobuso obuyindilinga. Noma yini enesimo ingaphrintwa ngokuphrinta kwesikrini. Ukuphrinta kwesikrini ezinkomishini kuvamile kakhulu

(9) Kungaba ukuphrinta kwesikrini sikasilika ngesandla noma ukuphrinta ngomshini

(10) Ifanele ukuboniswa isikhathi eside, futhi izikhangiso ezingaphandle ziveza imizwa yazo

Umqondo onamandla onezinhlangothi ezintathu:

Ngokuthungwa okucebile, ubukhulu bengqimba yeyinki yokunyathelisa kwe-offset kanye nokunamathisela i-embossing ngokuvamile bungama-microns angu-5, ukunyathelisa kwe-gravure kungaba ngama-microns angu-12, ubukhulu bengqimba yeyinki yokunyathelisa kwe-flexographic (aniline) bungama-microns angu-10, kanti ubukhulu bengqimba yeyinki yokunyathelisa kwesikrini budlula kakhulu ubukhulu bengqimba yeyinki engenhla, ngokuvamile bufinyelela kuma-microns angu-30. Ukunyathelisa kwesikrini okujiyile kwebhodi lesifunda elikhethekile elinyathelisiwe, ngobukhulu bengqimba yeyinki obufika kuma-microns angu-1000. I-Braille ye-Braille inyatheliswa ngoyinki one-foam, kanti ubukhulu bengqimba yeyinki ene-foam bungafinyelela kuma-microns angu-1300. Ukunyathelisa kwesikrini kunengqimba yeyinki ejiyile, ikhwalithi yokunyathelisa ecebile kanye nomuzwa onamandla onezinhlangothi ezintathu, ongenakuqhathaniswa nezinye izindlela zokunyathelisa. Ukunyathelisa kwesikrini akukwazi ukunyathelisa i-monochrome kuphela, kodwa futhi nokunyathelisa nge-chromatic kanye nokunyathelisa kombala wesikrini.

Ukumelana nokukhanya okunamandla:

Ngenxa yokuthi ukuphrinta kwesikrini kunezici zokuphrinta ezingekho, kungasebenzisa zonke izinhlobo zamayinki kanye nopende, hhayi nje kuphela i-slurry, i-glue kanye nemibala ehlukahlukene, kodwa futhi nemibala enezinhlayiya eziqinile. Ngaphezu kwalokho, i-inki yokuphrinta kwesikrini kulula ukuyisebenzisa, isibonelo, i-pigment engamelani nokukhanya ingafakwa ngqo kuyinki, okungenye isici sokuphrinta kwesikrini. Imikhiqizo yokuphrinta kwesikrini inezinzuzo ezinkulu zokumelana nokukhanya okuqinile. Lo mkhuba ubonisa ukuthi ngokwebanga lobuningi obukhulu elilinganiswa ngemva kokuqoshwa okukodwa ephepheni elimboziwe ngoyinki omnyama, ukuphrinta kwe-offset kungu-1.4, ukuphrinta kwe-convex kungu-1.6 kanye nokuphrinta kwe-gravure kungu-1.8, kanti ububanzi bobuningi obukhulu bokuphrinta kwesikrini bungafinyelela ku-2.0. Ngakho-ke, ukumelana kokukhanya kwemikhiqizo yokuphrinta kwesikrini kunamandla kunokwezinye izinhlobo zemikhiqizo yokuphrinta, okulungele kakhulu ukukhangisa kwangaphandle kanye nezimpawu.

Indawo enkulu yokunyathelisa:

Usayizi wendawo ophezulu ophrintiwe ngokuphrinta okujwayelekile kwe-offset, ukunamathisela izithombe kanye nezinye izindlela zokuphrinta usayizi weshidi eligcwele. Uma lidlula usayizi weshidi eligcwele, linqunyelwe imishini yemishini. Ukuphrinta kwesikrini kungasetshenziswa ekuphrinteni endaweni enkulu. Namuhla, ububanzi obukhulu bemikhiqizo yokuphrinta kwesikrini bungafinyelela amamitha angu-3 × 4 noma ngaphezulu.

Amaphuzu amane angenhla umehluko phakathi kokuphrinta kwesikrini nokunye ukuphrinta, kanye nezici nezinzuzo zokuphrinta kwesikrini. Qonda izici zokuphrinta kwesikrini, ekukhetheni izindlela zokuphrinta, singathuthukisa amandla futhi sigweme ubuthakathaka, siqokomise izinzuzo zokuphrinta kwesikrini, ukuze sifinyelele umphumela wokuphrinta ofanele kakhulu.

Ukugqwala kwe-UV:

Ukucwebezela kwe-UV kwendawo kubhekisela ekuphrinteni kwesikrini sesilika sephethini ekuphrinteni kokuqala okumnyama nge-varnish ye-UV. Ngemva kokusebenzisa i-varnish ye-UV, uma kuqhathaniswa nomphumela wokuphrinta ozungezile, iphethini yokupholisha ibonakala ikhanya, ikhanya futhi inobukhulu obuthathu. Ngenxa yokuthi ungqimba lweyinki lokuphrinta kwesikrini sesilika luwugqinsi, luzoqhuma ngemva kokuqina futhi lubukeke njengokufakwa kwembobo. Ukucwebezela kwe-UV kwesikrini sesilika kunamandla kune-UV engaphandle ngokuphakama, ukushelela kanye nobukhulu, ngakho-ke bekulokhu kuthandwa ngabathengisi bangaphandle.

Ukugqwala kwe-UV kwendawo kokunyathelisa isikrini sesilika kuxazulule inkinga yokunamathela efilimini i-Bop noma i-petpopp ngemva kokunyathelisa okumnyama, futhi kungaba yi-convex. Ayikwazi ukuklwebheka, ayigoqeki futhi ayinaphunga eliningi. Lokhu kudala indawo enkulu yemakethe, engasetshenziswa emasimini okunyathelisa njengezinkomishi, izimpawu zokuhweba, izincwadi, ukusakazwa nokunye.
