Mais la technologie traditionnelle de l'h\u00e9liogravure contient peu d'encre solide, la volatilisation des solvants est importante, de sorte que le point imprim\u00e9 n'est pas plein, l'effet de r\u00e9duction du point n'est pas aussi bon que l'impression offset ; en m\u00eame temps, en raison de la volatilisation des solvants, la concentration de l'encre change, ce qui affecte l'uniformit\u00e9 de la couleur de la mati\u00e8re imprim\u00e9e. Apr\u00e8s l'utilisation de l'impression UV, ces probl\u00e8mes ont \u00e9t\u00e9 compl\u00e8tement r\u00e9solus et l'effet de r\u00e9duction du point est sup\u00e9rieur \u00e0 celui de l'impression offset.<\/p>\n<p>Les \u00e9missions de compos\u00e9s organiques volatils (COV) provenant des encres provoquent une pollution de l'air, l'h\u00e9liogravure \u00e9tant le probl\u00e8me le plus grave. L'industrie mondiale de l'imprimerie est actuellement confront\u00e9e \u00e0 la question de savoir comment r\u00e9soudre compl\u00e8tement le probl\u00e8me des \u00e9missions de compos\u00e9s organiques volatils (COV) de l'h\u00e9liogravure.<\/p>\n<p>Les pays du monde entier d\u00e9veloppent et utilisent des encres d'h\u00e9liogravure \u00e0 base d'eau. Dans une certaine mesure, les encres d'h\u00e9liogravure \u00e0 base d'eau permettent de r\u00e9duire les \u00e9missions de compos\u00e9s organiques volatils (COV). Toutefois, l'effet d'impression de l'encre d'h\u00e9liogravure \u00e0 base d'eau, le sens de la hi\u00e9rarchie, l'\u00e9paisseur de la couche d'encre, l'uniformit\u00e9 de la couleur de l'encre, la clart\u00e9, la saturation, la vivacit\u00e9 de la couleur, etc. ne sont pas aussi bons que ceux de l'encre \u00e0 base de solvant. L'impression d'encres \u00e0 base d'eau doit s\u00e9cher \u00e0 des temp\u00e9ratures \u00e9lev\u00e9es, ce qui pose certaines difficult\u00e9s pour l'impression d'emballages souples en plastique pour les produits alimentaires, chimiques et pharmaceutiques quotidiens.<\/p>\n<p>L'h\u00e9liogravure et les autres m\u00e9thodes d'impression sont diff\u00e9rentes de la plaque d'impression apr\u00e8s la corrosion ou la gravure, la formation de nombreux trous d'encrage sous la surface de la plaque d'impression avec un volume diff\u00e9rent, ces trous d'encrage forment les graphiques de la plaque d'impression h\u00e9liogravure. Lors du processus d'impression, la surface du rouleau taille-douce est immerg\u00e9e dans le r\u00e9servoir d'encre, la surface des trous d'encrage est remplie d'encre, le racleur enl\u00e8ve l'exc\u00e9dent d'encre, seuls les trous d'encrage sont remplis d'encre, le rouleau taille-douce continue de tourner, le rouleau taille-douce encr\u00e9 est en contact avec le substrat et le rouleau d'impression, sous l'action de la pression, les trous d'encrage de l'encre sont en contact avec le substrat, l'encre est transf\u00e9r\u00e9e sur le substrat en raison de l'adsorbant du substrat. Le rouleau h\u00e9lio continuant \u00e0 tourner, la plaque d'encrage et le support se s\u00e9parent, une partie de l'encre est transf\u00e9r\u00e9e sur le support, une partie de l'encre retourne dans le trou d'encrage, ce qui termine le processus d'impression.<\/p>\n<p>&nbsp;<\/p>\n<p>Dans le processus d'impression, l'h\u00e9liogravure est plus simple que l'impression offset, il n'y a pas d'encre offset et d'\u00e9quilibre de l'eau, et elle est directement imprim\u00e9e, sa reproduction des couleurs et la coh\u00e9rence des couleurs sont meilleures, et le taux de rebut est faible, le gaspillage de substrat est moindre, en particulier la r\u00e9sistance de l'impression est beaucoup plus \u00e9lev\u00e9e que l'impression offset, le nombre d'impressions g\u00e9n\u00e9ralement jusqu'\u00e0 plus de 500 000 impressions, tr\u00e8s appropri\u00e9 pour l'impression d'emballages de tabac et de vin de haute qualit\u00e9. L'h\u00e9liogravure est la caract\u00e9ristique la plus importante de la couche d'encre de l'impression est plus \u00e9paisse, g\u00e9n\u00e9ralement dans les 9 ~ 20\u03bcm, presque deux fois plus \u00e9paisse que la couche d'encre de l'impression flexographique, l'impression a un fort sens de la tridimensionnalit\u00e9, des niveaux clairs, la couleur et l'\u00e9clat sont brillants et pleins.<\/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\/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\/photoinitiator-184-cas-947-19-3\/\">CHLUMINIT 184<\/a>:<\/strong> A classic free-radical benchmark for fast surface cure in many UV systems.<\/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<\/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.
