Munyaya yekudhinda mapurasitiki, michina yekudhinda ine mavara mana/6/8 ndiyo michina mikuru yekuwana kudhinda kwakanaka kwemavara akawanda. "Dhizaini yedhiramu repakati" (inozivikanwawo seCentral Impression, kana kuti CI, chimiro), nekuda kwekugadzirisa kwayo zvakanangana nezvinodiwa zvekudhinda kwemavara akawanda kwemichina yakadaro yeflexographic, yave mhinduro huru yehunyanzvi.
Sedhizaini yechimiro chakagadzirirwa kudhinda kwe4/6/8-color flexographic, Ci Type Flexo Printing Machine inoenderana nezvinodiwa zvekudhinda kwemavara akawanda. Inoratidza mabhenefiti akakosha asina kutsiviwa muzvikamu zvitatu zvakakosha: kutonga kwakarurama kwe multi-color pattern overlay, kuvandudza kushanda zvakanaka mukugadzirwa kunoramba kuripo, uye kuenderana ne substrates dzakasiyana - kupa rutsigiro rwepakati rwekugadzirwa kwepamusoro-soro, kwakasimba mukudhinda kwe multi-color flexographic.
Muchina wekudhinda weCentral Impression Ci Flexo une ruvara rwe8

I. Nzvimbo Yakajeka: Maitiro Ekushandisa Pakati Pemagadzirirwo Edhiramu Repakati
Kugadzirwa kwemidziyo yekudhinda kunoenderana nezvinodiwa zvekugadzirwa. Pakudhinda kwe4/6/8-color flexo, uko kuenderana kwemavara akawanda uye kunyatsojeka zviri izvo zvinodiwa, pfungwa yekugadzira dhizaini yedhiramu repakati inoita kuti pave nekuenderana kwakanangana.
Kubva pamaonero echimiro chepakati, muchina weCi Type Flexo Printing Machine unotarisa pa silinda imwe chete yakakura, ine dhayamita refu, ine mavara mana kusvika masere akarongwa mudenderedzwa. Munguva yekudhinda, nzvimbo dzese dzemavara dzinopedzisa maitiro ekudhinda nedhiramu iri repakati sereferensi yakabatana. Dhizaini iyi ye "centralized reference" inogadzirisa zvakanyanya dambudziko guru re "dispersed references" zvichiita kuti zvive nyore kutsauka mukudhinda kwemavara akawanda, zvichishanda serutsigiro rukuru rwekuburitsa kudhinda kwemavara akawanda mumichina yeflexographic ine mavara akawanda.

II. Zvinhu Zvina Zvikuru: Kuchinjana Kwedhiramu Repakati Kunoenderana Nezvinodiwa Zvekudhinda Nemavara Akawanda
1. Kunyoresa Kwakarurama: "Simba Rinovimbisa" Kuenderana Kwemavara Akawanda
Kudhinda kwemavara mana/6/8 kunoda kufukidza kwakanyatsojeka kwemavara akasiyana-siyana, uye Muchina wekudhinda weFlexo unovimbisa kunyatsojeka uku kubva panobva chinhu kuburikidza nedhiramu rawo repakati:
● Substrate inonamatira zvakanyanya kudhiramu repakati rakagadzika mukati menguva yese, ichideredza kushanduka kwekumanikidzwa mukudhindwa kwemavara akawanda uye ichidzivirira kuunganidzwa kwekutsauka kwenzvimbo;
● Nzvimbo dzese dzemavara dzinoshandisa dhiramu repakati rakafanana nereferensi yekuenzanisa, zvichibvumira kugadziriswa kwakanyatsojeka kwekumanikidzwa kwekubatana nenzvimbo iri pakati peplate yekudhinda ne substrate. Kururama kwerejista kunogona kusvika ±0.1mm, zvichizadzisa zvinodiwa zve overlay yakanaka yemapatani ane mavara akawanda;
● Kune zvinhu zvinotambanudzwa zvakaita semafirimu nepepa rakatetepa, rutsigiro rwakasimba rwedhiramu repakati runoderedza kushanduka kwechinhu, zvichiita kuti chive chakafanana nerejista yemavara akawanda.
2. Kuenderana kweSubstrate: Kuvhara Zvinodiwa Zvakasiyana-siyana zveKudhinda
Kudhinda kwe flexographic kwemavara mana/6/8 kunowanzo shandiswa pakubata zvinhu zvakasiyana-siyana, kusanganisira mapurasitiki (10–150μm), bepa (20–400 gsm), uye aluminium foil. Chimiro chedhiramu chepakati chinowedzera kuenderana nenzira dzinotevera:
●Drum yepakati pemuchina wekudhinda weci flexographic inowanzova nedhayamita ye ≥600-1200mm, ichipa nzvimbo yakakura yekuputira substrate uye kumanikidzwa kwakafanana. Izvi zvinogonesa kugadziriswa kudhindwa kwe substrate yakakora uye kudzivirira matambudziko ekupinda mukati memuchina;
●Inoderedza kusangana kweganda pakati pe substrate nema guide rollers akawanda, ichideredza njodzi yekukwenya nemakwinya pa substrates dzakatetepa (semuenzaniso, mafirimu ePE) uye ichichinja zvinoenderana nezvinodiwa zvekudhinda zvine mavara akasiyana-siyana.
3. Kushanda Nesimba Mukugadzira: "Kiyi Inowedzera Kukurumidza" Yekudhinda Nemavara Akawanda
Kushanda zvakanaka kwe 4/6/8-color printing hinges pa "synchronization" uye "order change flexibility" — zvinhu zviviri zvakagadziriswa nekugadzirwa kwedhiramu repakati:
● Kurongeka kwenzvimbo dzemavara dzakatenderera kunobvumira substrate kupedzisa kudhinda kwemavara akawanda panguva imwe chete, zvichibvisa kudiwa kwekutamiswa kwakatevedzana pakati penzvimbo. Kumhanya kwekugadzira kunogona kusvika 300m/min, kuchienderana nekugadzirwa kwakanaka kwemirairo mikuru yemavara akawanda;
● Munguva yekuchinja kwemavara, nzvimbo yega yega yemavara inogona kugadziriswa yoga yakatenderedza dhiramu repakati, pasina chikonzero chekugadzirisa zvakare nzvimbo iri pakati pemarori akawanda. Izvi zvinoderedza nguva yekuchinja marongero ne40%, zvichiita kuti ive yakakodzera kune zvinodiwa zvekudhinda kwenguva pfupi, zvine mavara akawanda.
4. Kushanda Kwenguva Refu: "Mhinduro Yekugadzirisa" Yemutengo Nekugadzirisa
Kubva pamaonero enguva refu, dhizaini yedhiramu repakati inovandudza mashandiro emuchina wekudhinda we central impression flexo:
●Kunyorwa kwacho kwakanyatsojeka kunoderedza mwero wekurasikirwa kwekudhinda. Pamamita gumi ega ega ekudhinda kwemavara akasiyana-siyana, kunoderedza zvakanyanya mari inoshandiswa netsvina ye substrate, zvichidzora kurasikirwa kwezvinhu zvakabikwa panobva chinhu;
●Kugadzirisa kunotarisa pazvikamu zvepakati pedhiramu repakati, kunoda kuongororwa nguva dzose kwemabheringi uye kutariswa kwereferensi. Kana tichienzanisa nemidziyo ine maroller akawanda akazvimiririra, mari yekugadzirisa yegore negore inoderedzwa ne25%.

III. Kugadziriswa kweIndasitiri: Kurongeka Pakati peDrum Yepakati neMaitiro Ekudhinda neFlexographic Yemavara Akawanda
Sezvo indasitiri yekurongedza ichivandudza kudiwa kwayo kwe "kuchengetedza nharaunda, hunyanzvi hwepamusoro, uye kushanda zvakanaka," michina yekudhinda ye flexo ine mavara mana/6/8 inofanirwa kuchinjika kune zvinhu zvitsva zvinoshandiswa senge inki dzinobva mumvura uye inki dzeUV. Hunhu hwakagadzikana hwedhiramu repakati hunoenderana nekukurumidza kwekuomesa uye mhedzisiro yekudhinda yeinki idzi itsva.
Zvichakadaro, maitiro e "madiki-batch, akawanda-pattern" mukupakata makemikari kwezuva nezuva akaita kuti mukana wekuchinja nekukurumidza kwedhiramu repakati unyanye kukosheswa.
