1.Mugumisiro wepepa pane ruvara
Kufurirwa kwebepa paruvara rweinki layer kunonyanya kuratidzwa muzvikamu zvitatu.
(1) Kuchena kwepepa: Pepa rine kuchena kwakasiyana (kana kuti rine rumwe ruvara) rine mhedzisiro yakasiyana pakuonekwa kweruvara rwekudhinda inki layer. Naizvozvo, mukugadzirwa chaiko, bepa rine kuchena kwakafanana kunofanirwa kusarudzwa kusvika pazvinogoneka kuti kuderedze pesvedzero yekuchena kwepepa pakudhinda ruvara.
(2) Absorbency: Kana iyo inki inodhindwa papepa ine absorbency yakasiyana pasi pemamiriro akafanana, ichava nekudhinda kwakasiyana-siyana. Kana ichienzaniswa nebepa rakavharwa, iyo inki dema yebepa risina kuvharwa ichaita grey uye matt, uye iyo inki layer inodonha. Ruvara rwakagadzirwa necyan ink uye magenta inki ndiyo inonyanya kuoneka.
(3) Kupenya uye kutsvedzerera: Kupenya kwechinhu chakadhindwa kunoenderana nekupenya uye kutsvedzerera kwepepa. Pamusoro pepepa rekudhinda isemi-glossy, kunyanya mapepa akavharidzirwa.
2.Effect yekurapa kwepamusoro pane ruvara
Iyo nzira dzepamusoro dzekurapa dzekurongedza zvigadzirwa dzinonyanya kusanganisira firimu rinofukidza (inopenya firimu, matt firimu), glazing (kuvhara mafuta anopenya, matt mafuta, uv varnish), etc. Mushure mekurapa kwepamusoro uku, iyo yakadhindwa ichava nemadhigirii akasiyana ekuchinja kwemavara uye kushanduka kwemavara. Kana iyo firimu yechiedza, mafuta akareruka uye uv mafuta akaputirwa, kusimba kwemavara kunowedzera; Kana yakaputirwa nematt firimu uye matt mafuta, density yemavara inoderera. Iko kushanduka kwemakemikari kunonyanya kubva kune akasiyana organic solvents ari mufirimu rinovhara adhesive, UV primer uye UV mafuta, iyo inoshandura ruvara rwekudhinda inki layer.
3.Impact yekusiyana kwehurongwa
Maitiro ekugadzira makadhi emavara ane inki leveler uye inki spreader inzira yakaoma yekudhinda, pasina kubatanidzwa kwemvura, nepo kudhinda kuri kunyorova kudhinda, nekubatanidzwa kwemvura yekunyorovesa mukudhinda, saka iyo inki inofanirwa kupinda mafuta- mu-mvura emulsification mu offset kudhinda. Iyo emulsified ingi ichaita zvisingadzivisiki kuburitsa mutsauko weruvara nekuti inoshandura kugoverwa kwepigment zvidimbu muinki layer, uye zvigadzirwa zvakadhindwa zvichaonekwawo zvakasviba uye zvisina kujeka.
Pamusoro pezvo, kugadzikana kweinki inoshandiswa kusanganisa mavara emavara, ukobvu hweinki layer, kunyatsoyera kuyera ingi, mutsauko pakati penzvimbo dzekare uye itsva dzekugovera inki yemuchina wekudhinda, kumhanya kwemuchina wekudhinda, uye huwandu hwemvura hunowedzerwa panguva yekudhinda huchavawo nemigumisiro yakasiyana pamusiyano wemavara.
4.Kudhinda kuzvidzora
Panguva yekudhinda, printa inodzora ukobvu hweiyo mavara inki layer neprinting yakajairwa kadhi reruvara, uye inobatsira mukuyera iyo huru density kukosha uye bk kukosha kweruvara ne densimeter kukunda mutsauko pakati pekuoma uye kunyorova kwemavara ingi.
