Na belichting met een negatief beeld valt het belichte deel van het siliconenrubber er na ontwikkeling af, waardoor de pro-inktlaag (grafisch) wordt belicht, en het onbelichte deel (blanco) van het siliconenrubber blijft behouden; het belichte deel van de lichtgevoelige laag daarentegen kruist zich met de siliconenrubberlaag om een afstotende inktlaag te worden na de ontwikkeling van de belichting met een positief beeld, en het onbelichte deel van de siliconenrubberlaag wordt verwijderd, wat resulteert in de vorming van een pro-inktlaag. Afbeelding 3-12 negatieve beeldbelichting als voorbeeld om het proces van het maken van waterloze offsetplaten te illustreren.<\/p>\n<p>Schematisch diagram van het proces voor het maken van negatieve beeldplaten voor waterloos offsetdrukken<\/p>\n<p>Waterloos offsetdrukken is vooral geschikt voor hoogwaardige, kleine oplagen en korte levertijden, zoals verpakkingen met toegevoegde waarde, plastic kaarten, zelfklevende etiketten, 3D-toepassingen, bolle spiegelvormen, cd's\/dvd's, plastic afdichtingen voor houtproducten, enzovoort. Het is vooral de moeite waard om te worden toegepast in sommige extreme drukgebieden.<\/p>\n<p>Omdat het blanco gedeelte van de waterloze offsetplaat niet beschermd wordt door een waterlaag en afhankelijk is van de afstoting van de inkt door de lage oppervlaktespanning van de siliconenrubberlaag, moeten waterloze offsetinkten een hoge cohesie hebben, d.w.z. er is een hoge viscositeit nodig om ervoor te zorgen dat de plaat niet vuil wordt (het blanco gedeelte van de plaat draagt geen inkt).<\/p>\n<p>Bij waterloos offsetdrukken is geen vuloplossing nodig, maar slechts \u00e9\u00e9n inktproces. Daarom is het vereist dat het grafische gedeelte van het inktproces de inkt goed absorbeert en het blanco gedeelte de inkt afstoot.<\/p>\n<p>Volgens de parameters van de oppervlakte-energie van de inkt, zolang de oppervlakte-energie van het grafische gedeelte hoger is dan de inkt, en de oppervlakte-energie van het blanco gedeelte lager is dan de inkt. In de keuze van het materiaal, om te voorkomen dat de inkt op het blanco gedeelte van de kleverige vuil, meestal het blanco gedeelte van de oppervlakte-energie ver onder de oppervlakte-energie van de inkt. Tegenwoordig is de meer volwassen niveau-vrije versie, waarvan het blanco gedeelte is samengesteld uit siliconenrubber, heeft een zeer lage oppervlakte-energie. Het grafische gedeelte is geselecteerd uit polyester met goede lipofiele inktoverdrachtseigenschappen.<\/p>\n<p>Waterloos offsetdrukken in het drukproces, als gevolg van de aanwezigheid van inktrollen en andere zachte rubberen rollen (rubberen materialen) hysteresiscirkel, zal de warmte die wordt gegenereerd door intern verbruik de inkttemperatuur doen stijgen en leiden tot een afname van de oppervlakte-energie. Wanneer de oppervlakte-energie tot op zekere hoogte afneemt, is het mogelijk om de normale oppervlakte-energierelatie tussen het blanco deel en de inkt te vernietigen, zodat het blanco deel van de inkt vuil wordt. Daarom moeten er verbeteringen worden aangebracht in de constructie van de drukpers. Kan tussen de zachte rubberrol holle de inktrol van het metaalkoord, aan de de inktrol van het metaalkoord door de lucht of het water en ander koelmiddel worden opgenomen, om de temperatuur van de inkt te controleren.<\/p>\n<p>Waterloze offsetdruk met behulp van een speciale inkt, de basissamenstelling en de traditionele offsetdruk inkt is vergelijkbaar met de keuze van de kleur is geen verschil, het belangrijkste verschil is de inkt die wordt gebruikt in de hars die is aangesloten op het materi\u00eble deel. Waterloze offsetdrukinkt en traditionele offsetdrukinkt vergeleken met de volgende speciale eigenschappen.<\/p>\n<p>\u2460 Het moet een hogere viscositeit en viscositeit hebben dan de traditionele offsetinkt, om een relatief grote inktcohesie te bieden, genoeg om groter te zijn dan de kracht tussen de inkt en de siliconenlaag, zodat de siliconenlaag oleofoob is, zodat de inkt en het niet-grafische deel van de siliconenrubberlaag afstoten, om waterloos drukken te bereiken.<\/p>\n<p>\u2461 moet zich aanpassen aan de speciale reologische eigenschappen van waterloos offsetdrukken. Omdat de waterloze offsetinkt een hoge viscositeit heeft, is het moeilijker om te circuleren tussen de inktrol en de drukplaat, waardoor de inkt een speciaal ontwerp moet hebben, zodat deze betere reologische eigenschappen heeft.<\/p>\n<p>\u2462 Vanwege de speciale invloed van temperatuur in waterloos offsetdrukken is het ook wenselijk om een breder temperatuuraanpassingsbereik te hebben.<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>How formulators usually evaluate this photoinitiator topic<\/h2>\n<p>When technical buyers or formulators screen photoinitiators, the most useful decision frame is usually cure quality plus application fit: which package cures reliably, keeps appearance acceptable, and still works under the lamp, film thickness, and substrate conditions of the actual process.<\/p>\n<ul>\n<li><strong>Match the package to the lamp first:<\/strong> mercury lamps, UV LEDs, and visible-light systems can rank the same photoinitiators very differently.<\/li>\n<li><strong>Check depth cure and surface cure separately:<\/strong> a film that feels dry on top can still be weak underneath.<\/li>\n<li><strong>Balance yellowing with reactivity:<\/strong> the strongest deep-cure route is not always the best commercial choice if color or migration risk becomes unacceptable.<\/li>\n<li><strong>Use the final formula as the benchmark:<\/strong> pigment load, monomer package, and film thickness can all change the apparent ranking of the same initiator.<\/li>\n<\/ul>\n<h3>Recommended product references<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/nl\/product\/photoinitiator-819-irgacure-819-cas-162881-26-7\/\">CHLUMINIT 819<\/a>:<\/strong> Useful when a formulation needs stronger absorption and deeper cure support.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/nl\/product\/irgacure-1173-cas-7473-98-5\/\">CHLUMINIT 1173<\/a>:<\/strong> A practical comparison point for classic short-wave UV initiation.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/nl\/product\/photoinitiator-itx-cas-5495-84-1\/\">CHLUMINIT ITX<\/a>:<\/strong> A useful long-wave support route in many printing-ink packages.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/nl\/product\/photoinitiator-cq\/\">CHLUMINIT CQ<\/a>:<\/strong> A direct reference for visible-light and color-sensitive curing discussions.<\/li>\n<\/ul>\n<h3>FAQ for buyers and formulators<\/h3>\n<p><strong>Why are blended photoinitiator packages so common?<\/strong><br \/>Because one product may control yellowing or lamp fit well while another improves cure depth or line-speed performance, so the full package is often stronger than any single grade.<\/p>\n<p><strong>Should incomplete cure always be solved by adding more initiator?<\/strong><br \/>Not automatically.
