Zvinyorwa Zvinyorwa Zvokudhinda Zviri kuverenga muChirongwa chekudhinda
Kunyange zvazvo nyika-ye-ye- yebhizimisi yekudhinda makambani ekufambisa ari kuendesa kudijita yekudhinda, vakawanda printers vanoramba vachishandisa nzira yakaedzwa-uye-yechokwadi yokudhinda offset nzira yave iri iyo inowanikwa mune zvekutengesa kwemakore anopfuura zana.
Offset Printing Process
Offset lithography-imwe yenzira yakawanda yekudhinda inki pamashandisi-anoshandisa mahwendefa okudhinda kuendesa mufananidzo kune pepa kana mamwe magasi. Mahwendefa acho anowanzoitwa nesimbi yakapetwa yesimbi, asi mune dzimwe nguva, mahwendefa anogona kunge ari plastiki, rubber kana pepa. Mapepa ematare inodhura kupfuura pepa kana mamwe mahwendefa, asi anogara kwenguva yakareba, anogadzira mifananidzo yakaisvonaka pamapepa uye ane kunyatsorurama kudarika ndiro yakagadzirwa nedzimwe zvinhu.
Mufananidzo unowanikwa pamahwendefa ekudhinda uchishandisa photomechanical kana photochemical process panguva yechikwata chekugadzirwa kunozivikanwa se prepress-imwe yekapu yega imwe yekinyorwa inofanira kudhindwa.
Maipiritsi okudhinda akabatanidzwa pamapuranga eplate pamichina yekudhinda. Inki nemvura zvinoshandiswa kune zvinogadziriswa uye zvadaro zvinoshandiswa kune imwe yemapuranga (blanket) uye ipapo kuvhara, umo inki inonamatira chete kumativi akafungidzirwa eplate. Ipapo inki inoendesa pepa.
Prepress Kugadzira Zvisarudzo
Basa rakadhindwa rinonyora chete muinki yakasviba rinoda ndiro imwe chete. Basa rakadhindwa rinonyora muinki tsvuku uye dema rinoda mahwendefa maviri. Pakati pese, iyo mahwendefa akawanda anodiwa kudhinda basa, iyo yakakwirira mutengo.
Zvinhu zvinowedzera zvakaoma apo mifananidzo yemifananidzo inobatanidzwa. Kugadziriswa kudhindwa kunoda kupatsanurwa kwemifananidzo yakatsvuka muine inki mavara-magenta, magenta, machena uye madema. IWYYK mafaira pakupedzisira ano mahwendefa mana anomhanya pamichina yekudhinda panguva imwechete pamakona mana. CMYK yakasiyana neRGB (tsvuku, ruvara, ruvara rwebhuruu) yemuenzaniso waunowona pakombiyuta yako. Dhijidhi dzefaira dzemabasa ose ekudhinda dzinoongororwa uye dzinogadziriswa kuderedza nhamba yeplateti inoda kudhinda purojekiti uye kuchinja mifananidzo yemifananidzo kana mafaira akaoma kune CYMK chete.
Mune zvimwe zviitiko, pangave pane mahwendefa anopfuura mana-kana chinyorwa chinofanira kuonekwa mune imwe ruvara rwePonone, somuenzaniso, kana kuti inki yesimbi inoshandiswa pakuwedzera kumifananidzo yakazara-mifananidzo.
Zvichienderana nehupamhi hwechopedzi chakadhindwa chigadzirwa, makopi akawanda emafaira angadhindwa papepa guru ndokuzogadzirirwa kusvika pakukura pashure. Apo basa rinonyora kumativi ose maviri epepeti, dhipatimendi rekugadzirira rinogona kuisa mufananidzo wacho kudhinda zvese zvakagadzirirwa pane imwe ndiro uye mushure mimwe kune imwe, kuiswa kunozivikanwa sepa sheetwise, kana nezvose zviri mberi uye kumashure pane imwe tsanda mune basa-uye-kutende kana basa-uye-tumble layout. Pakati peizvi, peji yejasi inowanzo inodhura nokuti inotora kaviri nhamba yeplateti. Zvichienderana nehukuru hweprojekiti, nhamba ye inks uye nekukura kwepepeti, dhipatimendi rekugadzirira rinosarudza nzira yakanakisisa yekuita basa iri pamahwendefa.
Dzimwe Plate Types
Muchikwangwani chinyorwa, chinyorwa chacho chakaenzana nekapu yekudhinda. Inogona kugadzirwa nemunhu kana kuti photochemically uye inowanzove chivara chepurasous kana simbi isina simbi yakasungirirwa pamusoro peforamu.
Mapeplate mapepa anowanzofanirwa chete nekudhindwa kwenguva pfupi pasina kuswedera pedyo kana kugunzva mavara anoda kubatwa . Ronga purogiramu yako kuitira kuti mapepa epombi anogona kushandiswa zvakanaka kana iwe uchida kuchengetedza mari. Havasi vese printers vepanhau vanopa izvi.
