Le processus d'impression de la tampographie consiste \u00e0 alimenter en encre la plaque d'impression par le dispositif d'alimentation en encre, le dispositif de raclage pour racler l'encre de l'espace vierge de la plaque d'impression, la pointe de tampographie est press\u00e9e sur la plaque d'impression, tremp\u00e9e dans l'encre dans la zone graphique, formant un graphique invers\u00e9 sur la surface de la pointe, puis la pointe d'impression multiple est emboss\u00e9e sur le substrat pour transf\u00e9rer l'encre sur le substrat afin de terminer l'impression.<\/p>\n<p>&nbsp;<\/p>\n<p>La tampographie et la s\u00e9rigraphie pr\u00e9sentent de nombreuses similitudes, telles que l'applicabilit\u00e9 d'une large gamme de substrats ; une large gamme d'encres, l'encre de tampographie et l'encre de s\u00e9rigraphie peuvent fondamentalement \u00eatre communes ; en rempla\u00e7ant le dispositif et la plaque d'impression, il est tr\u00e8s pratique d'achever l'impression de diff\u00e9rents produits et ainsi de suite. Par cons\u00e9quent, dans de nombreuses occasions d'impression, la tampographie et la s\u00e9rigraphie sont comme une paire de s\u0153urs jumelles aussi proches, jouant un r\u00f4le important dans la technologie d'impression sp\u00e9ciale.<\/p>\n<p>Cependant, les caract\u00e9ristiques de la tampographie et de la s\u00e9rigraphie et l'utilisation de la technologie pr\u00e9sentent certaines diff\u00e9rences. Tout d'abord, \u00e0 partir du processus de transfert d'encre, la tampographie et la s\u00e9rigraphie pr\u00e9sentent des diff\u00e9rences \u00e9videntes ; ensuite, la structure de la machine de tampographie et de la machine de s\u00e9rigraphie n'est pas la m\u00eame ; en outre, la technologie de la tampographie pour les cat\u00e9gories de produits et la s\u00e9rigraphie sont \u00e9galement tr\u00e8s diff\u00e9rentes. Objectivement, les diff\u00e9rences entre la tampographie et la s\u00e9rigraphie sont bien plus importantes que leurs similitudes. La raison pour laquelle on a l'habitude de les regrouper est que la tampographie et la s\u00e9rigraphie sont confront\u00e9es \u00e0 un march\u00e9 commun et que, dans ce march\u00e9 commun, la s\u00e9rigraphie ne peut pas \u00eatre s\u00e9par\u00e9e de la tampographie.<\/p>\n<p>Les caract\u00e9ristiques de la tampographie sont principalement les suivantes<\/p>\n<p>\u2460 Peut \u00eatre imprim\u00e9 sur des surfaces concaves et convexes de forme irr\u00e9guli\u00e8re.

La profondeur de la couche d'encre de la plaque d'impression \u00e9tant de 4\/9, l'impression de la couche d'encre est plus fine afin d'obtenir des graphiques plus accrocheurs.<\/p>\n<p>La pointe de l'adh\u00e9sif de tampographie est un proc\u00e9d\u00e9 unique, elle poss\u00e8de une excellente d\u00e9formabilit\u00e9 et r\u00e9silience, la pointe de l'adh\u00e9sif de tampographie dans la pression peut \u00eatre compl\u00e8tement avec la surface du substrat pour r\u00e9aliser l'impression. Cependant, dans le processus de tampographie, d'une part, la pointe adh\u00e9sive de la tampographie est soumise \u00e0 la pression g\u00e9n\u00e9r\u00e9e par la d\u00e9formation pour faire passer l'encre ; d'autre part, la d\u00e9formation de la pointe adh\u00e9sive de la tampographie entra\u00eene \u00e9galement une d\u00e9formation de l'impression et une augmentation du nombre de points. Afin de minimiser cet effet, la thixotropie de l'encre de tampographie est n\u00e9cessaire.<\/p>\n<p>3.8.2 Fabrication de plaques pour la tampographie<br \/>\nActuellement, les plaques d'h\u00e9liogravure utilis\u00e9es pour la tampographie comprennent les plaques d'h\u00e9liogravure en r\u00e9sine photopolym\u00e9ris\u00e9e et les plaques d'h\u00e9liogravure en acier corrosif pour la tampographie. L'application des plaques en r\u00e9sine photopolym\u00e8re au processus de tampographie ne date pas d'hier, mais en raison des nombreuses caract\u00e9ristiques des mat\u00e9riaux polym\u00e8res, telles que l'efficacit\u00e9 \u00e9lev\u00e9e de la fabrication des plaques, la facilit\u00e9 d'utilisation et d'autres avantages, l'industrie s'y int\u00e9resse de plus en plus. La m\u00e9thode de fabrication des plaques d'h\u00e9liogravure en r\u00e9sine photopolym\u00e8re est la m\u00eame que celle des plaques d'impression typographique en photopolym\u00e8re solide, \u00e0 savoir l'utilisation d'une image positive pour fabriquer la plaque. La r\u00e9sine photopolym\u00e8re est principalement du nylon photopolym\u00e8re, qui est coul\u00e9 sur la surface de la plaque de zinc. Le nylon a une tr\u00e8s bonne r\u00e9sistance \u00e0 l'abrasion, la photopolym\u00e9risation peut \u00eatre obtenue apr\u00e8s un point extr\u00eamement fin, en particulier pour la reproduction de petits tirages fins. Toutefois, la plaque d'h\u00e9liogravure en r\u00e9sine photopolym\u00e9ris\u00e9e pr\u00e9sente une faible duret\u00e9 de surface, une courte dur\u00e9e de vie et d'autres d\u00e9fauts, de sorte qu'elle ne convient qu'\u00e0 la production de petits lots.<\/p>\n<p>La tampographie des t\u00f4les d'acier est \u00e9galement connue sous le nom d'h\u00e9liogravure par corrosion des m\u00e9taux ; dans le processus de tampographie, les t\u00f4les d'acier occupent \u00e9galement une position dominante dans l'utilisation du courant. Lors de la gravure des graphiques avant la surface de la plaque d'acier, il convient de proc\u00e9der \u00e0 un meulage m\u00e9canique fin jusqu'\u00e0 l'obtention d'un fini miroir afin de s'assurer que la corrosion du bord des graphiques est nette, puis de garantir l'int\u00e9grit\u00e9 de la structure des points, de sorte que l'impression des graphiques soit la plus nette possible et que la reproduction des couleurs soit optimale, tout en garantissant la propret\u00e9 de l'encre ainsi que la r\u00e9sistance de l'impression. La production de plaques m\u00e9talliques est souvent utilis\u00e9e pour les m\u00e9thodes de gravure et de corrosion, le co\u00fbt de la gravure est relativement \u00e9lev\u00e9, seul un grand nombre de commandes d'impression en h\u00e9liogravure peut \u00eatre utilis\u00e9. La tampographie des t\u00f4les d'acier est principalement utilis\u00e9e dans la m\u00e9thode de corrosion. La raison en est que le co\u00fbt de la tampographie est tr\u00e8s faible et qu'il est difficile de supporter le co\u00fbt \u00e9lev\u00e9 du processus de gravure. La m\u00e9thode de corrosion utilis\u00e9e dans la production de plaques m\u00e9talliques depuis longtemps, en raison de l'agent corrosif qui est essentiellement une solution acide, entra\u00eene une grave pollution de l'environnement et est confront\u00e9e \u00e0 l'\u00e9limination d\u00e9finitive de cette m\u00e9thode.<\/p>\n<p>&nbsp;<\/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-tpo-l-cas-84434-11-7\/\">CHLUMINIT TPO-L<\/a>:<\/strong> A strong low-yellowing reference for LED-oriented UV systems.<\/li>\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<\/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.
