I-cylinder lining kanye nokulungiswa kwengcindezi
Isilinda sepuleti elimpunga eliphindwe kabili nebanga lesikhungo serabha alishintshile, kudingeka kuphela ukulungisa indawo emaphakathi yesilinda esibonakalayo nesilinda senjoloba, ekuphrinteni kwephepha elimpunga elingu-250-450g/m2 lingadonselwa phezulu ibanga lesikhungo lesilinda elingu-0.20- I-0.4mm, ngenxa yephepha elimpunga eliphindwe kabili elibushelelezi elibushelelezi limpofu, lilukhuni, ukuminyana kwephepha nakho kuncane kakhulu kunephepha le-Copperplate, ukuphrinta iphepha elimpunga eliphindwe kabili, kodwa futhi unake ingcindezi yokunyathelisa ngokuhambisanayo yanda kancane.
Okufana nokuphrinta i-400g / m2 yephepha elimpunga eliphindwe kabili, isilinda sepuleti lokuphrinta kanye negebe lesilinda lerabha elingu-3.95mm, isilinda senjoloba kanye negebe le-cylinder embossing lika-3.40mm, idolobhana lephakeji lepuleti lokuphrinta elingu-0.65-0.75mm, isamba se-rubber cylinder 15. -3.35mm (kukalwa nge-micrometer), uma Iphepha lisuka eliwugqinsi liye elincanyana, kufanele lincishiswe ubukhulu, ukushuba komugqa wephakeji kusuka kumugqa wokuphrinta wepuleti ukuze wengeze kusilinda senjoloba, uma iphepha lokuphrinta lisuka elincanyana liye koqweqwedi. , bese kusuka ku-liner yerabha yesilinda ukuze kuncishiswe ukujiya kokuthile, kanye nogqinsi oluhambisanayo kuya ku-liner yesilinda sepuleti lokuphrinta okufanele uhambe.
Ingxenye yokuphrinta ye-offset yokulungiswa kokulethwa kwephepha
1, ukuphrinta kwephepha elimpunga okuphindwe kabili engxenyeni yokulethwa kwephepha yenozi yokumunca kanye nevolumu yomoya yenozi yephepha ngokufanele ukuze ulungise enkulu.
2, umlomo wombhobho wokuhlukanisa iphepha, umbhobho wokuphakelayo wephepha esikhundleni sobubanzi obukhudlwana nobukhulu bendandatho yenjoloba, ukudonsa i-gauge compression spring kungashintshwa ngobubanzi be-1.5mm yensimbi yensimbi;ngokususa iphinikhodi yokuhlanganisa phakathi kwekhamera ye-feed roller kanye ne-shaft yayo, noma ukususa i-roller ku-pendulum ukuze kuzuzwe inhloso ye-feed roller yephepha ayishwibi, iphepha elibushelelezi.
3, Lapho uphrinta iphepha elimpunga eliphindwe kabili, igebe phakathi kokulawula okuphindwe kabili noma umshini wokunyathelisa we-offset kufanele likhuphuke ngokufanele;ibanga phakathi kwe-gauge eseceleni kanye ne-front gauge yolimi lwephepha lokucindezela kanye nokulethwa kwe-paperboard, kanye nebanga phakathi kwebha yokuphepha kanye nokulethwa kwe-paperboard kufanele kwandiswe okunye.
4, ukunikeza iphedi lezinyo lephepha kanye nobuso besilinda sombono futhi unikeze iphedi lezinyo lephepha kanye nebanga phakathi kwebhodi lephepha kufanele linyuswe, futhi ugcine ibanga elilingana nobukhulu bephepha lihlanganisa.
Ukuphrinta uhlelo lokulandelana kombala
1, imikhiqizo yokuphrinta yephepha empunga kabili inenguqulo yasensimini yaseHong Kong, nombhalo, imigqa, amaphethini.Isibonelo: izimvilophu ezikhethekile zemboni yeposi, amabhokisi ewayini, amabhokisi kagwayi amaphakheji angaphandle (amabhokisi e-strip) neminye imikhiqizo yokuphrinta, ukulandelana kombala wokuphrinta kungcono kakhulu ukuphrinta umbhalo, imigqa, amaphethini, bese kuba inguqulo egcwele yenkundla ekugcineni. ukuphrinta komshini, ukuze ukwazi ukugwema ukujiya kwephepha elimpunga eliphindwe kabili, ukuphrinta akomi lapho iphepha lishayisana ngenxa yokuthinta okungcolile ukuhlikihla okubi, okunamathelayo okungcolile emuva.
2, umbala omnyama ngaphambili kokuphrintiwe, umbala okhanyayo ngemuva kokuphrintiwe, ngenxa yokumbozwa kweyinki yombala omnyama, ukunamathela okuqinile, okubekwe ngaphambi kokuphrinta kokuqala, kulula ukuphrinta ngokunembile;Ukufakwa kwe-inki yombala okhanyayo kubuthakathaka, kufakwa ngemuva kwenani lokuphrinta eliphrintiwe umthetho wokugijima kancane akulula ukuwubona, umphumela wokuphrinta ungcono kakhulu.
I-3, ngokuvamile emkhiqizweni ophrintiwe, kukhona amaphuzu kagesi we-half-tone enemibala emine yenethiwekhi, namaphethini ethoni aqhubekayo, umbhalo, imigqa.Amaphuzu kagesi emibala emine wechashazi kufanele aphrintwe kuqala, okulungele ukuphrinta okunembile futhi kunciphise umthelela wokwelula iphepha.Bese uphrinta amaphethini ethoni aqhubekayo, umbhalo, imigqa, ilungiselelo lokulandelana kombala wokuphrinta kufanele kuqashelwe njengokubalulekile okuyinhloko, okokuqala kube nzima ngemva kokufaneleka kakhudlwana.
4, njengesimo sezulu esishisayo, iphepha elimpunga eliphindwe kabili eliphrintiwe i-monochrome lapho uhlangabezana namanzi angalingani ephepheni, ukungalingani okushwabene, ukuqina kwephepha eliphansi, njll. okubangelwa ukuwa kwempushana, izinwele, njll., kungaphinda kushaye kuqala ukuphrinta okungenalutho emanzini, ingaxazulula lesi simo.
