PS ipleyiti

Ipleyiti ye-PS intsingiselo yipleyiti eyenziwe ngaphambili esetyenziswa kushicilelo lweoffset. Kushicilelo lweoffset, umfanekiso oza kuprintwa uvela kwiphepha eligqunyiweyo lealuminiyam, elibekwe malunga nesilinda sokushicilela. I-aluminium iphathwa ukuze indawo yayo ibe yi-hydrophilic (iheha amanzi), ngelixa i-PS plate ephuhlisiwe yokugubungela i-hydrophobic.
Ipleyiti ye-PS ineendidi ezimbini: ipleyiti ye-PS ene-positive kunye ne-negative PS plate. Kuzo, ipleyiti ye-PS ithatha isabelo esikhulu, esisetyenziswa kuninzi lwemisebenzi yoshicilelo oluphakathi ukuya kolukhulu namhlanje. Itekhnoloji yokwenza kwayo nayo ivuthiwe.
Ipleyiti ye-PS yenziwe nge-substrate kunye ne-PS yokugqoka ipleyiti, oko kukuthi, i-photosensitive layer. I-substrate ubukhulu becala yi-aluminiyam base plate. Umaleko wefotosensitive ngumaleko owenziwe ngokugquma i-photosensitive liquid kwi-base plate.
Amacandelo ayo aphambili yi-photosensitizer, i-agent-forming agent kunye ne-agent encedisayo. I-photosensitizer edla ngokusetyenziswa kwiipleyiti ze-PS ezinyibilikayo idiazonaphthoquinone yohlobo lwe-photosensitive resin ngelixa kwipleyiti ye-PS engalunganga ayinyibiliki i-azide-based photosensitive resins.
Ipleyiti ye-PS e-positve ineenzuzo zobunzima bokukhanya, ukusebenza okuzinzileyo, imifanekiso ecacileyo, iileya ezityebileyo, kunye nomgangatho ophezulu wokushicilela. Ukwenziwa nokusetyenziswa kwayo kulutshintsho olukhulu kushishino lokushicilela. Okwangoku, ipleyiti ye-PS iye yadityaniswa nokusetwa kohlobo lwe-elektroniki, ukwahlulwa kwemibala nge-elektroniki, kunye noshicilelo lwe-multicolor offset, oluye lwaba yeyona nkqubo iphambili yokwenziwa kweeplate namhlanje.
