Ngokusetyenziswa kwezixhobo zokuprinta ezingenakufunxa ezifana nekhadibhodi yegolide kunye nesilivere kunye nephepha lokudluliselwa kwelaser kwiipakethe zecuba, itekhnoloji yoshicilelo ye-UV offset nayo isetyenziswa kakhulu ekushicileleni ipakethe yesigarethi.Nangona kunjalo, ulawulo lwenkqubo yoshicilelo ye-UV ye-offset nayo inzima kakhulu, kwaye iingxaki ezininzi zomgangatho zilula ukwenzeka kwinkqubo yokuvelisa.
I-inki roller glaze
Kwinkqubo yoshicilelo lwe-UV ye-offset, i-glossy glaze phenomenon iya kwenzeka xa i-inki roller ibaleka ngesantya esiphezulu ixesha elide, okukhokelela kwi-inking embi, kwaye ibhalansi ye-inki kunye namanzi kunzima ukuqinisekiswa.
Kufunyaniswa kwimveliso eyiyo ukuba ibhetshi yeerola ezintsha aziyi kuvelisa iglaze ekhazimlayo kwinyanga yokuqala yokusetyenziswa, ngoko ke ukuntywiliselwa iirola zeinki kwi-inki roller yokunciphisa intlama kangangeeyure ezi-4 ukuya kwezi-5 nyanga nganye kunokubuyisela ngokupheleleyo ukusebenza kwe-inki. iirola ze-inki, ngaloo ndlela kunciphisa ukuveliswa kweglaze ekhazimlayo yeerola ze-inki.
Ukwandiswa kwerola ye-inki
Njengoko sonke sisazi, i-inki ye-UV igqwesa kakhulu, ngoko ke i-roller ye-inki ejikelezwe yi-inki ye-UV offset nayo iya kwanda.
Xa i-inki roller isanda, amanyathelo afanelekileyo onyango kufuneka athathwe ngexesha lokuphepha imiphumo emibi.Eyona nto ibaluleke kakhulu kukuthintela ukwanda kubangele uxinzelelo olugqithisileyo kwi-roller ye-inki, kungenjalo kuya kubangela amaqamza, ukuphuka kwejel kunye nezinye izinto, kwaye kubangele umonakalo obulalayo kwi-UV kwisixhobo sokushicilela kwi-UV kwiimeko ezinzima.
Ushicilelo lobuxoki
Ukungachaneki koshicilelo kwi-UV offset yoshicilelo lweepakethi zecuba kunokwahlulwa ngokwezi ntlobo zimbini zilandelayo.
(1) Ushicilelo lwedekhi yokunyanga i-UV ayiqinanga.
Kule meko, ukulandelelana kombala kufuneka kucwangciswe ngokufanelekileyo, kwaye isibane se-UV phakathi kombala wemibala kufuneka sigwenywe ngokusemandleni.Ngokuqhelekileyo, umaleko we-inki emhlophe yoshicilelo lokuqala uqina kwaye unyango lwe-UV luyenziwa;Xa uprinta i-inki emhlophe okwesihlandlo sesibini, umaleko we-inki uya kucuthwa ngaphandle kokunyangwa kwe-UV.Emva kokushicilela ngokugqithisileyo kunye nezinye iidekhi zombala, umphumo osicaba nawo unokufezekiswa.
(2) Indawo enkulu yokushicilela intsimi asiyonyaniso.
Zininzi izinto ezichaphazela ummandla omkhulu woshicilelo lwasentsimini.Ukuze ugweme indawo enkulu yokushicilela kwintsimi, jonga kuqala ukuba i-inki yoxinzelelo lwe-inki ichanekile ukuqinisekisa ukuba i-inki roller ayinayo i-glaze;Qinisekisa ukuba iiparamitha zenkqubo yesisombululo somthombo zichanekile;Umphezulu wengubo awuyi kuba nokungcola, imingxuma, njl njl. Ukongeza, uvavanyo lubonakalise ukuba ukunyanzeliswa komoya kweqela emva kokuprintwa kwendawo enkulu kuya kuba nefuthe elikhawulezayo ekuphuculeni ukunyanzeliswa kwendawo enkulu yoshicilelo.
Ukutsalwa kwe-inki ngasemva
Kushicilelo lwe-UV offset, ukutsalwa kwe-inki ngasemva kukusilela okuqhelekileyo, ngakumbi ngenxa yokuba i-inki yoshicilelo ye-UV ayinyangekanga ngokupheleleyo emva kokukhanya kwe-UV, kwaye ayincanyathiselwa ngokuqinileyo kwi-substrate.Ngaphantsi kwefuthe loxinzelelo loshicilelo lweedekhi zombala ezilandelayo, i-inki itsalwa kwaye inamathele kwingubo yeminye imibala yombala.
Xa ukutsalwa kwe-inki ngasemva kwenzeka, ngokuqhelekileyo kunokusombulula ngokunciphisa umthamo wamanzi weqela le-UV lokunyanga umbala, ukwandisa umthamo wamanzi weqela lombala we-inki lomzobo, kunye nokunciphisa uxinzelelo lokushicilela lweqela lombala we-inki;Ukuba ingxaki ayikasonjululwa, yinyange ngeUV
Le ngxaki inokuphuculwa ngokongeza inani elifanelekileyo le-arhente yokuqina kwi-inki yedekhi yombala.Ukongeza, ukuguga kwengubo yerabha kukwasisizathu esibalulekileyo se-inki yokutsala umva.
Ushicilelo lwebhakhowudi embi
Ukuprintwa kwe-UV offset yeepakethe zecuba, umgangatho wokuprintwa kwebhakhowudi luphawu oluphambili.Ngaphezu koko, ngenxa yokubonakaliswa okunamandla kwekhadibhodi yegolide kunye nesilivere ekukhanyeni, kulula ukubangela ukuba ukubonwa kwekhowudi yebha kungazinzi okanye kuphantsi.Ngokubanzi, kukho iimeko ezimbini eziphambili xa i-UV offset barcode yepakethe yecuba isilela ukuhlangabezana nomgangatho: idigri yesiphene kunye nedigri ye-decoding.Xa idigri yesiphene ingekho kumgangatho, khangela ukuba i-inki emhlophe yoshicilelo isicaba kwaye ingaba iphepha ligqunywe ngokupheleleyo;Xa i-decodeability ingekho kumgangatho, jonga i-inki emulsification yedekhi yombala woshicilelo lwebhakhowudi nokuba ibarcode ineghosting.
Iinki zokuprinta ze-UV ezinezigaba ezahlukeneyo zemibala zinokugqithisela okwahlukileyo kwi-UV.Ngokubanzi, i-UV kulula ukungena etyheli kunye ne-magenta ye-UV yokuprinta i-offset, kodwa kunzima ukungena kwii-inks zokuprinta ezimnyama ze-UV, ngakumbi ii-inks zokushicilela ezimnyama ze-UV.Ke ngoko, kushicilelo lwe-UV ye-offset, ukuba ubukhulu be-inki ye-UV emnyama bonyusiwe ukuphucula isiphumo soshicilelo lwebhakhowudi, oko kuya kukhokelela ekomisweni kakubi kwe-inki, ukuncamathela okulambathayo komaleko we-inki, kulula ukuwa, kwaye nokuba kubi. ukuncamathela.
Ke ngoko, ingqwalasela eyodwa kufuneka ihlawulwe kubunzima bomaleko we-inki emnyama ekushicileleni kwe-UV ukuthintela ibhakhowudi ukuba ingancamatheli.
Ukugcinwa kwe-inki yokushicilela ye-UV offset
I-inki yokuprinta ye-UV kufuneka igcinwe kwindawo emnyama engaphantsi kwama-25 ℃.Ukuba igcinwe kubushushu obuphezulu, i-inki yoshicilelo ye-UV iya komelela kwaye ibe lukhuni.Ngokukodwa, i-Ink ye-UV yegolide kunye nesilivere ithanda ukuqiniswa kunye neglosi engalunganga kune-inki ye-UV ye-offset, ke kungcono ungayigcini ixesha elide.
Ngamafutshane, inkqubo yoshicilelo ye-UV offset kunzima ukuyilawula.Amagcisa amashishini oshicilelo lwepakethe yesigarethi kufuneka aqwalasele ngononophelo kwaye ashwankathele imveliso yoshicilelo.Ngokwesiseko sobuchule bolwazi oluyimfuneko lwethiyori, ukudibanisa ithiyori namava kulungele ngakumbi ukusombulula iingxaki ekuhlangatyenwe nazo kushicilelo lwe-UV offset.
