Par rapport \u00e0 la technologie d'impression offset traditionnelle, l'impression offset sans eau pr\u00e9sente les avantages d'un excellent effet d'impression, d'une plus grande efficacit\u00e9 d'impression et de la protection de l'environnement.<\/p>\n<p>3.4.4.1 Caract\u00e9ristiques de la technologie d'impression offset sans eau<br \/>\n(1) Bon effet d'impression<br \/>\n\u2460 Haute saturation des couleurs. Il n'y a pas d'intervention d'eau dans l'impression, l'image imprim\u00e9e n'est pas dilu\u00e9e et l'encre \u00e9mulsionn\u00e9e et plus lumineuse, vive, la saturation des couleurs de l'impression augment\u00e9e, peut d\u00e9passer l'impression traditionnelle de 20%.<\/p>\n<p>\u2461 Bonne reproduction du point. La plaque d'impression est une plaque plate concave, le transfert de gaufrage sur tous les c\u00f4t\u00e9s du degr\u00e9 de diffusion est faible, le taux d'augmentation du point est r\u00e9duit de 50%, et n'utilisez pas de solution de mouillage, le point est plus clair.<\/p>\n<p>\u2462 Haute densit\u00e9 d'impression. Le taux d'engraissement des points \u00e9tant faible, la densit\u00e9 d'impression peut \u00eatre augment\u00e9e de mani\u00e8re appropri\u00e9e pour produire des tons de couleur clairs, des images haute r\u00e9solution et haute luminosit\u00e9, des textes fins et des images de pr\u00e9cision.<\/p>\n<p>\u2463 Comme aucune eau n'est utilis\u00e9e, il n'est pas n\u00e9cessaire d'ajuster l'\u00e9quilibre entre l'eau et l'encre, et davantage de substrats peuvent \u00eatre s\u00e9lectionn\u00e9s, comme les performances exceptionnelles sur les feuilles m\u00e9talliques, les plastiques et les films qui ne peuvent pas \u00eatre imprim\u00e9s par l'impression offset conventionnelle.<\/p>\n<p>\u2464 L'absence de solution de mouillage permet \u00e9galement une surimpression pr\u00e9cise sur les presses recto-verso, en particulier pour l'impression de papier fin.<\/p>\n<p>(2) Vitesse d'impression et productivit\u00e9 \u00e9lev\u00e9es<br \/>\nL'impression offset sans eau ne n\u00e9cessitant pas d'ajuster l'\u00e9quilibre eau-encre lors de l'impression, le temps de pr\u00e9presse est 40% plus court que celui de l'impression offset traditionnelle, la consommation de papier de surimpression est r\u00e9duite de 30% \u00e0 40%, et aucune solution de fontaine d'impression n'est utilis\u00e9e. Cela permet non seulement d'\u00e9conomiser du temps et des co\u00fbts de pr\u00e9paration de l'impression, mais aussi d'obtenir une production de haute qualit\u00e9 et de haute efficacit\u00e9.<\/p>\n<p>(3) Favorable \u00e0 la protection de l'environnement<br \/>\nLe proc\u00e9d\u00e9 d'impression offset sans eau n'utilise pas de solution de mouillage offset traditionnelle contenant des solvants volatils tels que des produits chimiques, n'\u00e9met pas de compos\u00e9s organiques volatils dans l'air, r\u00e9duit la pollution de l'environnement et \u00e9conomise l'eau.<\/p>\n<p>Bien entendu, l'impression offset sans eau pr\u00e9sente \u00e9galement des inconv\u00e9nients, tels que la viscosit\u00e9 de l'encre, les exigences en mati\u00e8re de qualit\u00e9 du papier ; et pour garantir que la viscosit\u00e9 de l'encre n'est pas affect\u00e9e par la temp\u00e9rature, il est n\u00e9cessaire de configurer le syst\u00e8me de contr\u00f4le de la temp\u00e9rature, ce qui entra\u00eene une augmentation de certains co\u00fbts.<\/p>\n<p>\u00c0 l'heure actuelle, l'utilisation g\u00e9n\u00e9rale de la plaque d'impression offset sans eau photosensible traditionnelle diff\u00e8re d'une entreprise \u00e0 l'autre et d'une p\u00e9riode de d\u00e9veloppement \u00e0 l'autre, mais la structure g\u00e9n\u00e9rale de la plaque d'impression est g\u00e9n\u00e9ralement divis\u00e9e en cinq couches (de l'int\u00e9rieur vers l'ext\u00e9rieur) : la base de la plaque, la couche inf\u00e9rieure (couche adh\u00e9sive), la couche photographique pro-encre (couche photosensible), la couche de caoutchouc silicone hydrofuge et la couche protectrice.<\/p>\n<p>3.4.4.2 Composition structurelle des plaques d'impression offset sans eau<br \/>\n(1) Socle de la plaque<br \/>\nLa base de la plaque est le support de la plaque d'impression, qui doit pr\u00e9senter un certain degr\u00e9 de r\u00e9sistance et de flexibilit\u00e9. Les plaques minces en aluminium sont principalement utilis\u00e9es, mais aussi le papier couch\u00e9, les plaques en alliage d'aluminium, les plaques en caoutchouc et les plaques en plastique ou une combinaison de plusieurs mat\u00e9riaux.<\/p>\n<p>(2) Sous-couche<br \/>\nLe rev\u00eatement inf\u00e9rieur est la base de la plaque et la couche photographique coll\u00e9es ensemble dans la couche adh\u00e9sive, outre le r\u00f4le d'adh\u00e9rence, il joue \u00e9galement un r\u00f4le d'isolation thermique et de tampon de la pression d'impression.<\/p>\n<p>(3) Couche photographique<br \/>\nLa couche de photopolym\u00e9risation, \u00e9galement connue sous le nom de couche de conversion de la lumi\u00e8re et de la chaleur, avec l'encre pro, est le support de l'image imprim\u00e9e, c'est la composition de base de la plaque d'impression offset sans eau, la couche de photopolym\u00e9risation est divis\u00e9e en deux types : le type n\u00e9gatif et le type positif.<\/p>\n<p>(4) Couche de caoutchouc silicon\u00e9<br \/>\nLa tension superficielle du caoutchouc de silicone et de l'encre est sup\u00e9rieure \u00e0 la coh\u00e9sion de l'encre, de sorte que la couche de caoutchouc de silicone peut \u00eatre utilis\u00e9e comme couche r\u00e9pulsive pour l'encre des plaques d'impression. Le caoutchouc de silicone est g\u00e9n\u00e9r\u00e9 par la r\u00e9action du polysiloxane dialkyl\u00e9 et de l'agent de r\u00e9ticulation.<\/p>\n<p>(5) Couche protectrice<br \/>\nLa couche de caoutchouc de silicone est parfois recouverte d'une couche de film de polyester ou de polypropyl\u00e8ne avec une bonne transmission de la lumi\u00e8re, ce qui peut emp\u00eacher la plaque de se rayer et am\u00e9liorer le vide pendant l'exposition.<\/p>\n<p>&nbsp;<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>A practical selection route for photoinitiator-related projects<\/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\/fr\/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\/fr\/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\/fr\/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\/fr\/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.
