Iwo Mechanics eOffset Printing Machines: Kunzwisisa Maitiro

Kuprinda kwave kure zvikuru kubvira pakwakavambwa, nemitoo yakasiana-siana yokudhinda iri kuvandudzwa nokuvandudzwa mumakore apfuura. Pakati pemitoo iyi, kudhinda kweoffset kwakabuda seimwe yenzira dzakakurumbira uye dzinoshandiswa nevakawanda. Michina yokudhinda yeoffset yakachinja magadzirirwo akawanda, zvichiita kuti zvikwanisike kudhinda mavhoriyamu makuru emhando yepamusoro nekukurumidza uye nenzira inobudirira. Muchinyorwa chino, tichaongorora magadzirirwo emichina yekudhinda yeoffset, tichiongorora maitiro akaomarara anoitika kuseri kwezviitiko.

Iwo Nheyo dzeOffset Printing Machines

Kuprinda kweoffset inzira inosanganisira kutamisa mufananidzo kubva mundiro kuenda kugumbeze rerabha usati waendeswa panzvimbo inodhinda. Iyo yakavakirwa pamusimboti wekuramba pakati pemafuta nemvura, nenzvimbo dzemufananidzo dzinokwezva inki uye nzvimbo dzisiri dzemufananidzo dzinoidzinga. Michina yekudhinda yeOffset inoshandisa nhevedzano yemaitiro akaoma kunzwisisa uye zvikamu kuita izvi.

Zvinhu zvakakosha zvemuchina wekuprinda we offset zvinosanganisira silinda yeplate, silinda yegumbeze, uye silinda ye impression. Aya masilinda anoshanda pamwechete kuti ave nechokwadi chekufambisa inki chaiyo uye kuburitswa kwemifananidzo. Silinda yeplate inobata ndiro yekutsikirira, iyo ine mufananidzo unofanirwa kudhindwa. Gumbeze humburumbira rine gumbeze rerabha rakaipoteredza, iro rinogamuchira ingi kubva mundiro uye inoendesa kune pepa kana imwe substrate yekudhinda. Pakupedzisira, iyo silinda yekufungidzira inoshandisa kumanikidza kune bepa kana substrate, kuve nechokwadi chekuenderana uye kunyange kutamiswa kwemufananidzo.

Iyo Inking System

Chimwe chezvinhu zvinonyanya kukosha pamuchina wokudhinda weoffset iinking system yayo. Iyo inking system ine nhevedzano yema rollers, imwe neimwe iine basa chairo. Aya ma roller ane basa rekutamisa ingi kubva pachisipiti cheinki ichiendesa mundiro uyezve pagumbeze.

Tsime reinki ndiro dhamu rinochengeta ingi, iyo inobva yaendeswa kune ingi rollers. Iyo inki rollers inosangana zvakananga ne fountain roller, inotora ingi uye ichiendesa kune ductor roller. Kubva kune ductor roller, inki inotamirwa kune cylinder yeplate, iyo inoshandiswa kune nzvimbo dzemufananidzo. Iyo inki yakawandisa inobviswa neakatevedzana oscillating rollers, kuve nechokwadi chekuti chaiyo uye inodzorwa huwandu hweinki inoshandiswa kune ndiro.

Iyo Plate neBlanket Cylinder

Silinda yeplate negumbeze humburumbira zvinotamba mabasa akakosha mukugadzirisa kudhinda. Silinda yeplate inobata ndiro yekudhinda, iyo inowanzogadzirwa nealuminium kana polyester. Mumichina yemazuva ano yekudhinda yeoffset, marata acho anowanzo kuve mahwendefa e-computer-to-plate (CTP), ayo anofananidzwa zvakananga achishandisa lasers kana inkjet tekinoroji.

Silinda yeplate inotenderera, ichibvumira ndiro yacho kuti ibatane neinki rollers uye kuendesa ingi kune cylinder yegumbeze. Sezvo silinda yeplate inotenderera, inki inokwezvwa kunzvimbo dzechifananidzo pandiro, iyo yakabatwa sehydrophilic kana inki-inogamuchira. Nzvimbo dzisiri dzemufananidzo, kune rumwe rutivi, dzine hydrophobic kana ink-repellent, kuve nechokwadi kuti mufananidzo unodiwa chete unotamiswa.

Silinda yegumbeze, sezita raro rinoratidza, yakafukidzwa negumbeze rerabha. Gumbeze rinoshanda semurevereri pakati peplate nebepa kana imwe substrate yekudhinda. Iyo inogamuchira inki kubva mundiro cylinder uye inoendesa kune bepa, kuve nechokwadi chekuchenesa uye kunoenderana kuchinjisa mufananidzo.

The Impression Cylinder

Iyo impression cylinder ine basa rekuisa kumanikidza kune bepa kana substrate, kuve nechokwadi chekuti chifananidzo chafambiswa nemazvo. Inoshanda pamwe chete negumbeze cylinder, ichigadzira sandwich-yakafanana nekugadzirisa. Sezvo humburumbira yegumbeze ichiendesa ingi pabepa, silinda yechiratidzo inoshandisa dzvinyiriro, zvichiita kuti ingi ipinde neshinda dzepepa.

Iyo silinda yekufungidzira inowanzo gadzirwa nesimbi kana chimwe chinhu chakasimba kutsungirira kudzvanywa uye kupa ratidziro inowirirana. Izvo zvakakosha kuti cylinder yekufungidzira ishandise huwandu hwakakodzera hwekumanikidza kuti ive nechokwadi chekufambisa kwemufananidzo pasina kukuvadza bepa kana substrate.

The Printing Process

Kunzwisisa magadzirirwo emuchina wekuprinda weoffset hakuna kukwana pasina kunzvera mukati memaitiro ekudhinda pachawo. Kana iyo ingi yaiswa kune cylinder yegumbeze, yakagadzirira kuendeswa kune pepa kana substrate.

Sezvo bepa richipfuura nemuchina wokudhinda, rinosangana negumbeze humburumbira. Mufananidzo wacho unotamirwa kune bepa kuburikidza nekubatanidzwa kwekumanikidza, inki, uye absorbency yepepa pachayo. Iyo silinda yegumbeze inotenderera mukuwirirana nebepa, kuve nechokwadi chekuti nzvimbo yese yakafukidzwa nemufananidzo.

Kudhinda kweoffset kunogadzira madhindi akapinza uye akachena, nekuda kwekugona kwayo kuchengetedza inki inopindirana panguva yese yekudhinda. Izvi zvinoguma nemavara anoyevedza, mashoko akanaka, uye mashoko akapinza, zvichiita kuti kudhinda kweoffset kuve sarudzo inodiwa pakushandisa kwakasiyana-siyana, kusanganisira magazini, mabhurocha, uye zvokurongedza.

Muchidimbu

Michina yekuprinda yeOffset yakasandura indasitiri yekudhinda, zvichiita kuti kudhindwe kwakawanda kwemhando yepamusoro nekururama kunoshamisa uye nemazvo. Iwo makanika ari kuseri kwemichina iyi anosanganisira kupindirana kwakaoma kunzwisisa pakati pezvinhu zvakasiyana, kusanganisira silinda yeplate, silinda yegumbeze, uye silinda yekufungidzira. Iyo inking system inogonesa kuendeswa kweinki mundiro uye gumbeze, nepo kudhinda pachayo kunovimbisa kuchena uye kunoenderana kubereka kwemifananidzo.

Kunzwisisa magadzirirwo emichina yekuprinda yeoffset kunopa ruzivo rwakakosha mumaitiro ekudhinda, zvichiita kuti vese nyanzvi nevanofarira vafarire hunyanzvi nesainzi kuseri kweiyi tekinoroji inoshamisa. Sezvo tekinoroji yekudhinda ichiramba ichishanduka, kudhinda kweoffset kunoramba kuri nzira yakatsiga uye yakavimbika, inotsigira maindasitiri akasiyana pasi rose.
