Muhupenyu hwedu hwezuva nezuva, tinowanzo shandisa makapu akasiyana-siyana epepa anoraswa, uye tinogona kuona kuti makapu mazhinji epepa ane mapatani. Kudhinda mapatani akanaka pamakapu epepa hakungounzi mufaro kune vanonwa chete, asiwo nzira yakanaka yekusimudzira kambani. Asi mapatani acho anodhindwa sei pamakapu epepa?
Kazhinji zvinhu zvakagadzirwa nemakapu emapepa ndeizvi: bepa repasi rehuni rine purasuru yekudya + firimu rePE rine purasuru yekudya, iro rinonzi bepa rakafukidzwa nePE remhando yepamusoro yechikafu. Patani iri pakapu yepepa inodhindwa zvakananga papepa rakaputirwa nePE, uye pepa rakadhindwa rinochekwa kuita mafeni ekapu yepepa akapedzwa, uye pakupedzisira mafeni ekapu yepepa akachekwa anogadziriswa nemuchina wekapu yepepa. Rutivi rwakafukidzwa nePE firimu rusvingo rwemukati rwekapu yepepa, rune mabasa ekusapinda mvura, anodzivirira mafuta uye anodzivirira kupisa. Rutivi rusina firimu rusvingo rwekunze rwekapu yepepa, Unoda chete kudhinda mapatani kurutivi urwu.
Nzira yekudhinda feni yekapu yepepa - Flexographic Printing
Kudhinda kweFlexographic kuri mumhando yeletterpress uye pari zvino ndiyo nzira inonyanya kushandiswa pakudhinda makapu epepa. Kudhinda kweFlexographic kunoshandisa inki dzemvura, inki dzeUV, uye inki dze solvent. Iyi tekinoroji yekudhinda ine girini uye isingakuvadzi nharaunda inoshandiswa zvakanyanya mukurongedza chikafu nekudhinda.
Chinhu chinonyanya kukosha pakudhinda neflexographic ndiro ndiro rekudhinda, iro rinogadzirwa zvakanyanya neplate resin inochinjika kana rabha. Inki inotamisirwa kuchikamu chegrafiki cheplate rekudhinda ne inki fountain rubber roller uye anilox roller kuti iite inki, uye ipapo kumanikidzwa kwekudhinda kunoiswa ne impression cylinder kuti iendese inki iri paplate rekudhinda kune printing paper roll. Pakupedzisira, infrared hot air drying kana UV curing drying inopedzisa kudhinda.
Nanning Paperjoy inonyanya kupa mapepa akadhindwa asina kupedzwa mafeni ekapu yepepa uye mapepa akaputirwa nePE ekapu yepepa. Tine michina yepamusoro yekudhinda ine mavara akawanda uye mainjiniya vane ruzivo. Tibatei kuti muzive kuti Paperjoy ingabatsira sei pakudhinda mafeni emakapu emapepa.
