Iindaba kunye neCofa

Emva kweminyaka engama-40 yophuhliso, i-China iye yaba lelona mvelisi libalaseleyo kunye nomthengi kushishino lweelebhile. Ukusetyenziswa kweelebhile ngonyaka malunga ne-16 yeebhiliyoni zee-square metres, malunga nekota yokusetyenziswa kweelebhile zizonke. Phakathi kwazo, ukusetyenziswa kweelebhile ezincamathelayo kubalelwa ngaphezulu kwesinye kwisithathu sokusetyenziswa kweelebhile zizonke eTshayina, ezizezi 6 billion ukuya kwi-7 yeebhiliyoni zeemitha zesikwere, kwaye ezinye zilayile zamaphepha, iileyibhile zefilimu ezinciphayo, iilebhile ezikwimold. kunye neelebhile zemikhono

Ukuprinta ileyibhile yamaTshayina, ngakumbiadUshicilelo lweleyibhile elukhuni, luphenjelelwa kakhulu yiJapan. Okwangoku, i-letterpress printing accounts imalunga nama-60%, iseyeyona nto iphambili kushishino loshicilelo lwalebhile; Iiakhawunti zoshicilelo ezingasetiyo malunga ne-20% kwaye yeyona ndlela ikhula ngokukhawuleza yoshicilelo; I-akhawunti yokushicilela i-Flexography malunga ne-10%, yeyona ndlela ifanelekileyo yokuprinta, kodwa echaphazelekayo yizinto ezahlukeneyo e-China, okwangoku ifakwe ngobuninzi, i-boot encinci. Enye i-10% yoshicilelo lwedijithali kunye nezinye iindlela zokuprinta ezifana noshicilelo lwesikrini, ushicilelo lwegravure kunye noshicilelo olukhethekileyo.

1. Ukushicilelwa kwedijithali

Ushicilelo lweDijithali yeyona teknoloji ikhawulezayo iphuhlayo kwicandelo loshicilelo lwelebhile. Ngokuqhelekileyo, ushicilelo lwedijithali lusebenzisa i-inkjet, i-toner, i-inki ye-elektroniki kunye neendlela zokudlulisa inkjet.

Eyona nto ibetha kakhulu kushicilelo oludibeneyo, oludibanisa ushicilelo lwedijithali kunye noshicilelo lwemveli.

2. Ushicilelo lwemibala esixhenxe

Ukuprintwa kwemibala esixhenxe, eyaziwa ngokuba yi "high-fidelity printing", yandisa i-gamut yombala kwaye iphucula kakhulu umgangatho wombala wezinto eziprintiweyo. Ukusebenzisa ibala loshicilelo lokwaleka kwamachaphaza endaweni yebala elikhethekileyo loshicilelo lwe-inki yombala, akukho mfuneko yokumisela i-inki yombala okhethekileyo, ukunciphisa ukusetyenziswa kwezinto kunye neendleko; Xa umshicileli eprinta ii-odolo ezininzi, kufuneka kuphela ukutshintsha ipleyiti ngaphandle kokucoca iibhedi kunye nokutshintsha i-inki, ephucula ukusebenza kakuhle kwemveliso.

3. Ukuprintwa kwe-offset engenamanzi

Isebenzisa i-inki yokudlulisa ephantsi, isetyenziswe kwisixhobo sokudlulisa i-inki ye-roller, i-viscosity ye-inki kunye nokwahlukana kombala woshicilelo unokuhlengahlengiswa ngokungenamkhethe, umbala wokuprinta uhambelana, ukuchaneka okuphezulu kokuprinta, ngamaxesha angama-2 ~ 3 ezixhobo zokuprinta iileyibhile eziqhelekileyo.

4. Ushicilelo lweFlexography

I-Flexography luhlobo lokushicilela olusebenzisa iipleyiti ze-flexo kunye nokudlulisa inki nge-anilox roller. Ipleyiti yoshicilelo ye-Flexographic ngokuqhelekileyo isebenzisa ubukhulu be-1-5mm ipleyiti ye-resin ye-photosensitive. I-inki yahlulwe yangamacandelo amathathu, ngokulandelelanayo i-inki esekwe emanzini, i-inki enyibilikayo ngotywala, i-UV. NjengokoI-inki yoshicilelo ye-flexographic iluhlaza, isetyenziswe ngokubanzi ekuprintweni kokupakishwa kokutya kwaye inethemba elibanzi.

5. Ukuprintwa kwepleyiti yePS

I-PS ipleyiti yokushicilela i-self-adhesive ilebula ineendleko eziphantsi zokwenza i-offset plate kunye nesiphumo esihle sokushicilela, umatshini weleyibhile we-offset lukhetho lokuqala lwamashishini oshicilelo lwelebhile ngaphezu komatshini we-letterpress wendabuko. Ushicilelo lwe-Offset lwenza iziphene zemizobo ye-letterpress, ixabiso lokwenza iipleyiti liphantsi, lilungele zonke iintlobo zee-odolo, zamkelwe ngamashishini oshicilelo lwelebhile.

6. Ushicilelo lwe-Letterpress

Olona phawu lukhulu lweletterpress lufutshane, lucaba, lukhawuleza, amashishini aprintayo anokwenza ipleyiti yawo, i-inki yokushicilela, isiphumo esihle seshelufu, ukusebenza okulula, ukulungelelaniswa lula, kukulungele zonke iintlobo zeemveliso zeelebhile eziphakathi.

Umatshini we-Letterpress wahlulwe kakhulu ngokweendidi ezimbini: omnye ngumatshini ojikelezayo wesiqingatha, owaziwa ngokuba ngumatshini we-letterpress intermittent; Enye yi-rotary letterpress epheleleyo. Nangona ushicilelo lwelebhile ye-letterpress lungakhange lubonwe kumashishini oshicilelo lweleyibhile ephezulu eTshayina, isengamandla aphambili oshicilelo lwelebhile yokuncamathelisa kumashishini amancinci naphakathi oshicilelo lweleyibhile, ebalelwa malunga ne-60%, kwaye le meko ayisayi kutshintsha. kwixesha elifutshane.

7. UShicilelo oludityanisiweyo

Ushicilelo oludityanisiweyo kukuphumeza iindlela ezininzi ezahlukeneyo zoshicilelo kwisixhobo esinye, esinokuthi siphunyezwe ngokubanzi koomatshini bokushicilela be-flexography,

Ukuprintwa kokudibanisa kwendabuko ngokuqhelekileyo kusekelwe kwinhlanganisela yokushicilela i-flexography, ukuba kuyimfuneko, yongeza isitampu esibandayo, ukuprintwa kwesikrini, inyathelo elinye lokugqiba ukuprinta. Ushicilelo oludityanisiweyo ngokwengqiqo yanamhlanje ludibaniso loshicilelo lwedijithali kunye noshicilelo lwemveli, oko kukuthi, ileyibhile inezoshicilelo zemveli kunye noshicilelo lwedijithali olunomxholo oguquguqukayo, lwenza umgca wokuvelisa idatha oguquguqukayo.

8. CTP : computer-to-plate

Umkhombandlela wophuhliso lwetekhnoloji yoshicilelo yidijithali, kwaye idijithali iqala kushicilelo lwangaphambili. Ishishini leleyibhile liye laqaphela ngokusisiseko i-CTP plate yenza kwi-flexography kunye nokushicilela i-offset, kodwa izinga lokungena kwe-CTP ipleyiti yokwenza kwi-letterpress kuphela malunga ne-10%, kwaye imboni yeleyibhile yaseChina ubukhulu becala yi-letterpress, ngoko ke ukwenza ipleyiti ye-CTP kunemarike enkulu enokubakho kwi-letterpress. ishishini laleyibhile.

9. Imathiriyeli yeleyibhile ekwimold

Ileyibhile ekwimold yenye yezona mveliso zikhawulezayo eziphuhlayo kwikhonkco loshishino lweleyibhile ekhaya naphesheya. Inembali ephantse ibe yi-30 iminyaka e-China. Ineempawu ezimbini: okokuqala, inefuthe elihle lokuhombisa kwaye i-caviar kwi-general kwi-label family; Okwesibini, ngenxa yokuba akukho phepha lesiseko, kuphela umaleko wefilimu, ileyibhile inokuphinda isetyenziswe kunye nesitya, ngoko ke iimpawu zokukhusela indalo zilungile. Ileyibhile ekwimold ikwayindlela yokuhombisa ekhuthazwa lishishini lokupakisha kunye noshicilelo lwamazwe ngamazwe. Yahlulwe yangamacandelo amabini: ukubumba ukuvuthela kunye nokubumba inaliti.
