Kunzwisisa Tekinoroji Kuseri kweOffset Printing Machines

Nhanganyaya:

Michina yekudhinda yeoffset inoita basa rakakosha mukugadzirwa kwakawanda kwezvinhu zvemhando yepamusoro zvinodhinda. Kubva mumapepanhau nemagazini kusvika kumabhurocha uye kurongedza, kudhinda kweoffset yave nzira inosarudzika yekudhinda kwekutengesa. Asi michina iyi inoshanda sei? Ndeipi tekinoroji iri seri kwekushanda kwavo? Muchinyorwa chino, tichanyura mukati mekuoma kunzwisisa kwemichina yekudhinda yeoffset, tichiongorora zvikamu zvayo, magadzirirwo ayo, uye maitiro. Ungave uri shasha yekudhinda kana kuti unongoda kuziva nezve tekinoroji inoita kuti zvinhu zvakadhindwa zvipenyu, chinyorwa chino chinokupa kunzwisisa kwakadzama kwekushanda kwemukati memichina yekuprinda yeoffset.

Izvo zvakakosha zveOffset Printing:

Kudhinda kweoffset inzira ine mukurumbira inoshandiswa kugadzira mifananidzo uye zvinyorwa panzvimbo dzakasiyana siyana, kazhinji bepa. Izwi rekuti "offset" rinoreva kutamiswa kwechifananidzo kubva mundiro yekudhinda kuenda kune substrate. Kusiyana nenzira dzekudhinda dzakananga, dzakadai seletterpress kana flexography, kudhinda kweoffset kunoshandisa murevereri - gumbeze rerabha - kuendesa chifananidzo pane substrate. Iyi nzira inopa akawanda mabhenefiti, anosanganisira epamusoro emhando yemifananidzo, chaiyo kubereka kwemavara, uye kugona kudhinda pane zvakasiyana siyana zvezvinhu.

Izvo Zvikamu zveOffset Printing Machine:

Michina yekuprinda yeOffset masisitimu akaomarara anoumbwa nezvikamu zvakakosha zvakati wandei zvinoshanda pamwechete zvakabatana. Kunzwisisa kushanda kwechikamu chimwe nechimwe chinhu chakakosha pakunzwisisa tekinoroji iri kumashure kwemichina yekudhinda yeoffset. Ngationgororei zvikamu izvi zvakadzama:

The Printing Plate:

Pamwoyo wemuchina wega wega wekudhinda pane ndiro yekutsikirira - pepa resimbi kana ndiro yealuminium inotakura mufananidzo kuti udhindwe. Mufananidzo uri mundiro unogadzirwa kuburikidza ne prepress process, apo ndiro inotaridzirwa kune UV chiedza kana chemakemikari mhinduro, kushandura nzvimbo dzakasarudzwa kuita kuti dzigamuchire inki. Iyo ndiro inobva yanamirwa kune cylinder yeplate yemuchina wekudhinda, ichibvumira kunyatsoita uye kuwirirana kwemufananidzo kubereka.

Inking System:

Iyo inking system ine basa rekuisa inki kune inodhinda ndiro. Iyo ine nhevedzano yema rollers, anosanganisira tsime roller, inki roller, uye distributor roller. The fountain roller, yakanyura mutsime reinki, inounganidza ingi uye inoendesa kune inki roller. Iyo inki roller, zvakare, inotamisa ingi kune distributor roller, iyo yakaenzana kuparadzira ingi pane inodhinda ndiro. Iyo inking sisitimu yakanyatso kucheneswa kuti ive nechokwadi chekugadzirwa kwemavara kwakaringana uye kugovera inki kunoenderana.

Iyo Blanket Cylinder:

Mushure mekunge chifananidzo chacho chaendeswa mundiro yekudhinda, inoda kuendeswa mberi kune yekupedzisira substrate. Apa ndipo panopinda gumbeze rerabha. Humburumbira yegumbeze inotakura gumbeze rerabha, rinotsikirirwa pandiro yekutsikirira kuti rigamuchire mufananidzo weinki. Kubatsira kwekushandisa gumbeze rerubha ndiko kushanduka kwayo, kuchibvumira kuti ienderane nemakona e substrate. Sezvo humburumbira yegumbeze inotenderera, mufananidzo weinki unoiswa pagumbeze, wakagadzirira nhano inotevera yegadziriro yacho.

The Impression Cylinder:

Kuti uendese chifananidzo kubva mugumbeze kuenda kune substrate, gumbeze uye substrate zvinoda kusangana nemumwe. Izvi zvinowanikwa kuburikidza neiyo impression cylinder. Iyo silinda yekufungidzira inotsikirira substrate pagumbeze, ichibvumira iyo inki mufananidzo kutamiswa. Dzvinyiriro inoshandiswa inofanira kunyatsodzorwa kuti ive nechokwadi chekudhinda mhando uye kudzivirira kukanganisa kune substrate. Iyo impression cylinder inogona kugadziridzwa kuti igadzirise ma substrates ehukobvu hwakasiyana, ichiita kuti kudhindwa kwe offset kuenderane kune akasiyana maapplication.

Iyo Pepa Nzira:

Padivi pezvinhu zvakakosha, muchina wekudhinda weoffset unewo nzira yepepa yakanyatsogadzirwa kuti itungamire substrate kuburikidza nekudhinda. Iyo nzira yemapepa ine akati wandei ma roller uye macylinders anobvumira kushanda uye kwakaringana substrate kubata. Kubva pachikwata chekudyisa kusvika kune chikwata chekuendesa, nzira yepepa inochengetedza kufamba kwakanaka kwe substrate, kuchengetedza kunyoresa uye kuderedza dambudziko rejamu remapepa. Nzira yepepa chaiyo yakakosha pakuwana mibairo yekudhinda yehunyanzvi.

Iyo Offset Printing process:

Zvino zvataongorora mativi makuru omuchina wokudhinda weoffset, ngatimbonyatsoongororai danho nedanho rinobatanidzwa mukugadzira zvinhu zvakadhindwa.

Prepress:

Kudhinda kusati kwatanga, ndiro yokudhindira inofanira kugadzirirwa. Izvi zvinosanganisira kuisa pachena ndiro kune UV chiedza kana kemikari zvinogadzirisa, izvo zvinosandura zvimiro zvayo zvepasi kuti zvigamuchire inki. Kana ndiro yagadzirira, inosungirirwa kune silinda yeplate, yakagadzirira kugamuchira inki.

Ink Application:

Sezvo ndiro yekudhinda ichitenderera pahumburumbira yeplate, iyo inking system inoshandisa inki kumusoro kwayo. The fountain roller inounganidza ingi kubva muchitubu cheinki, inozoendeswa kune inki roller yogovaniswa zvakaenzana pandiro yekudhinda. Nzvimbo dzisiri dzemufananidzo weplate, dzinodzinga mvura, dzinochengetedza inki, nepo nzvimbo dzemufananidzo dzinogamuchira inki nekuda kwekurapa kwavo panguva yeprepress.

Kuendesa Ink kuBlanket:

Mushure mekunge ingi yaiswa mundiro yekudhinda, mufananidzo wacho unobviswa pagumbeze rerabha sezvo humburumbira yegumbeze inosangana nendiro. Gumbeze rinogashira mufananidzo weinki, uyo zvino wadzoserwa kumashure uye wagadzirira kuendeswa kune substrate.

Kuchinjisa mufananidzo kune Substrate:

Nemufananidzo weinki unogara pagumbeze, iyo substrate inounzwa. Silinda yekufungidzira inodzvanya substrate pagumbeze, ichiendesa mufananidzo weinki pamusoro payo. Dzvinyiriro inoiswa inovimbisa yemhando yepamusoro fungidziro pasina kukuvadza iyo substrate.

Kuomesa uye Kupedza:

Kamwe iyo substrate yagamuchira iyo inki mufananidzo, inopfuurira kuburikidza nekuomesa muitiro kubvisa chero hunyoro hwasara uye nekumhanyisa inki kurapa. Nzira dzakasiyana dzekuomesa, dzakadai semarambi ekupisa kana ma air dryer, dzinoshandiswa kukurumidza danho iri. Pashure pokuwomeswa, zvakadhindwa zvingaitwa mamwe magadzirirwo okupedzisa, zvakadai sokucheka, kupeta, kana kuti kusunga, kuti zviwane fomu rokupedzisira raunoda.

Mhedziso:

Michina yekudhinda yeOffset musanganiswa unoshamisa weinjiniya chaiyo uye tekinoroji yepamusoro. Iko kusanganiswa kwezvikamu zvakasiyana-siyana, kubva mundiro yekudhindisa uye inking system kusvika kugumbeze nemasilinda ekufungidzira, inobvumira kugadzirwa kwemhando yepamusoro yekudhinda zvinhu zvine ruvara rwemhando yepamusoro uye kugadziriswa. Kunzwisisa tekinoroji iri kumashure kwemichina iyi kunopa nzwisiso yakakosha mukuoma kwemaitiro ekudhinda uye nhanho dzehungwaru dzinobatanidzwa mukugadzira zvinhu zvehunyanzvi zvekudhinda. Kunyangwe iwe uri anoshuvira printa kana kungonakidzwa nenyika yeoffset kudhinda, kuongorora mukati mehunyanzvi hwetekinoroji yemuchina wekudhinda weoffset inopa tarisiro inonakidza muhunyanzvi nesainzi yekugadzirwa kwekudhinda.
