Ukuphrinta, njengoba kuhlukaniswa nokudaya, inqubo lapho udayi noma i-coating isetshenziselwa indwangu ukuze wenze iphethini.

Ngo-1784, amaFulentshi amathathu asungula imboni yokuqala yokunyathelisa ukotini emhlabeni.

Eminyakeni engu-230 edlule, ubuchwepheshe bokunyathelisa buye bathuthuka ngezindlela ezihlukahlukene.Namuhla, i-encyclopedia xiaobian izohlola izinhlobo zokuphrinta

I. Ukuhlukaniswa ngokwenqubo yokuphrinta:

1. Ukuphrinta okuqondile (Ukuphrinta ngaphezulu, ukuphrinta okumanzi)

Ukuphrinta okuqondile kuwuhlobo lokuphrinta ngokuqondile endwangu emhlophe noma endwangu edayiwe ngaphambili.Lokhu kokugcina kubizwa ngokuthi i-overprint (eyaziwa nangokuthi ukuphrinta okuphansi), futhi vele ukuphrinta kumnyama kakhulu kunombala ongezansi.Cishe i-80% yezindwangu eziphrintiwe emakethe ziphrintiwe ngokuqondile.(Lapha ukuphrinta okuqondile ngokuvamile kubhekisela ekunyathelisweni kodayi, okusetshenziselwa ukuhlukanisa kusukela ekuphrintiwe ngopende ngezansi)

Umbuzo: Ungahlukanisa kanjani ukuphrinta okumhlophe kokuphrinta kodayi?

Uma umbala wangemuva wendwangu ungumthunzi ofanayo ezinhlangothini zombili (ngenxa yodayi wesiqeshana) futhi ukuphrinta kumnyama kakhulu kunombala wangemuva, khona-ke kuwukuphrinta kwekhava, ngaphandle kwalokho kuwukuphrinta okumhlophe.

2. Khipha ukuphrinta

Khetha ukuthi ungafaki odayi ukuze udayi isisekelo sokunamathisela okukhiphayo, ukumelana nokomisa, sebenzisa okokugeza okuqukethe i-ejenti yokukhipha noma ukumelana nokukhipha ngesikhathi esifanayo umklamo nombala wokuphrinta kokunamathisela okuphrinta udayi, ukucubungula, ukuphrinta emhlabathini kuyabhujiswa futhi i-decolorization kadayi, umbala womhlaba wakha iphethini emhlophe (okuthiwa ukukhishwa okumhlophe) noma iphethini yombala eyakhiwe umklamo nombala odayi wokudaya (okuthiwa ukuphrinta kombala).Kwaziwa nangokuthi ukudonsa okumhlophe noma ukudonsa umbala.

Ngokuphambene nokunyathelisa okuqondile, izindleko zokukhiqiza izindwangu eziphrintiwe ziphakeme, futhi ukunakekelwa okukhulu nokunemba kufanele kuthathwe ukulawula ukusetshenziswa kwe-ejenti yokunciphisa edingekayo.

Umbuzo: Ungahlukanisa kanjani ukuthi indwangu iyiphrinta yokukhipha?

Uma indwangu inombala ofanayo ezinhlangothini zombili zangemuva (ngoba idayi yesiqephu), futhi iphethini imhlophe noma ihluke ngemuva, futhi ingemuva imnyama, ingaqinisekiswa njengendwangu yokunyathelisa yokukhishwa.

Ukuhlola ngokucophelela uhlangothi olungemuva lwephethini kuveza imikhondo yombala wangemuva wangempela (lokhu kwenzeka ngoba amakhemikhali abhubhisa udayi awangeni ngokugcwele endwangu).

3, anti-daying ukuphrinta

Ikhemikhali noma i-waxy resin ephrintwe endwangu emhlophe evimbela noma evimbela ukungena kukadayi endwangu.Inhloso ukunikeza umbala wesisekelo ozobonisa iphethini emhlophe.Qaphela ukuthi umphumela uyafana nokunyathelisa kokukhipha, nokho indlela esetshenziselwa ukufeza lo mphumela iphambene nokunyathelisa kokukhipha.

Indlela yokuphrinta yokudaya ayisetshenziswa kakhulu, ngokuvamile ngemuva ayikwazi ukusetshenziswa uma kukhishwe.Ukuphrinta okuningi okuvikela udayi kwenziwa ngezindlela ezifana nobuciko noma ukuphrinta ngesandla (isb. ukuphrinta nge-wax) kunokuba kwenziwe ngokukhiqiza ngobuningi.

Ngoba ukuphrinta kokukhishwa kanye nokuphrinta okulwa nokudaya kukhiqiza umphumela ofanayo wokuphrinta, ngakho-ke ngokujwayelekile ngokubuka ngeso lenyama ngokuvamile akukwazi ukubonakala.

Shisa ukuphrinta (Shisa ukuphrinta)

Ukuphrinta okubolile kuyiphethini ephrintiwe ngamakhemikhali adiliza indwangu.Ngakho ukuxhumana phakathi kwamakhemikhali nendwangu kungaveza izimbobo.Unqenqema lwezimbobo kumaphrinti adabukile ahlala egugile ngaphambi kwesikhathi, ngakho-ke indwangu ayinazo ukumelana nokugqokwa.

Olunye uhlobo lokuphrinta okubolile yindwangu eyenziwe ngezintambo ezihlanganisiwe, izintambo eziphonswe ngomgogodla, noma ingxube yemicu emibili noma ngaphezulu.Amakhemikhali angabhubhisa i-fiber eyodwa (i-cellulose), ashiye eminye iphelele.Le ndlela yokunyathelisa ingakhiqiza izindwangu eziningi zokunyathelisa ezikhethekile nezithakazelisayo.

5, ukushwabana kwembali/ukuphrinta kwegwebu

Ukusebenzisa indlela yokuphrinta endwangu yokusetshenziswa kwendawo kwamakhemikhali kungenza ukunwetshwa kwefayibha noma ukufinyela, ngokwelashwa okufanele, ukuze ingxenye ephrintiwe yefiber kanye nengxenye engaphrintiwe yokwandiswa kwefayibha noma umehluko wokufinyela, ukuze kutholwe. ubuso bephethini evamile ye-concave kanye ne-convex yomkhiqizo.Okufana nokusetshenziswa kwe-ejenti yokukhukhumeza ye-caustic soda ye-seersucker ephrintiwe kakotini emsulwa.Kwaziwa nangokuthi ukuphrinta kwe-convex.

Izinga lokushisa elinegwebu ngokuvamile lingu-110C, isikhathi imizuzwana engu-30, futhi isikrini sokuphrinta singu-80-100 mesh.

6, Ukuphrinta kwe-Coating (Pigment Print)

Ngenxa yokuthi ukugqoka akuyona into enemibala encibilikayo emanzini, akukho ukuhambisana nefayibha, umbala wayo kufanele uncike embotsheni yefilimu eyenza i-polymer compound (i-adhesive) kanye ne-fiber adhesion ukuze uzuze.

Ukuphrinta impahla yokumboza kungasetshenziselwa ukucutshungulwa kwanoma yiziphi izindwangu ze-fiber, futhi kunezinzuzo ezengeziwe ekunyatheliseni ama-blends kanye nama-interweaves, futhi inqubo ilula, i-spectrum ebanzi, uhlaka lwe-flower shape lucacile, kodwa umuzwa awulungile, ukuxubha. ukushesha akuphakeme.

Ukuphrinta upende ukuphrinta okuqondile kopende, okuvame ukubizwa ngokuthi ukuphrinta okomile ukuze ukuhlukanise nokuphrinta okumanzi (noma ukuphrinta kodayi).

Zinokushesha okuhle noma okuhle kakhulu kokukhanya kanye nokushesha kokuhlanza okomile, ngakho-ke zisetshenziswa kabanzi ezindwangu zokuhlobisa, izindwangu zamakhethini nezingubo ezidinga ukuhlanza okomile.
