Buyers usually compare a blended package instead of one isolated product.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>L'impression est un \u00e9l\u00e9ment important pour garantir l'uniformit\u00e9 de la couleur de l'encre, mais c'est aussi un processus qui pr\u00e9sente de fortes exigences techniques. L'op\u00e9rateur doit non seulement poss\u00e9der un certain degr\u00e9 de connaissances et de comp\u00e9tences professionnelles pour r\u00e9gler la machine, mais aussi une grande exp\u00e9rience. Pour garantir l'uniformit\u00e9 de la couleur de l'encre de s\u00e9chage UV, il convient d'examiner les aspects suivants.<\/p>\n<p>1) Pression d'impression<\/p>\n<p>L'impression ne peut \u00eatre s\u00e9par\u00e9e de la pression, dans l'impression offset, la source de sa pression est le blanchet \u00e9lastique, suivi par la pression entre les trois cylindres d'impression, entre les rouleaux encreurs et les rouleaux encreurs, les rouleaux encreurs et les plaques d'impression, les rouleaux d'eau et les rouleaux d'eau, les rouleaux d'eau et les plaques d'impression entre la pression. Ils s'influencent mutuellement et d\u00e9terminent ensemble la quantit\u00e9 d'encre \u00e0 s\u00e9chage UV transf\u00e9r\u00e9e de la plaque d'impression \u00e0 l'impression et la qualit\u00e9 de l'impression.<\/p>\n<p>\u2460 Les rouleaux encreurs et les rouleaux encreurs, les rouleaux encreurs et la pression entre la plaque d'impression sont g\u00e9n\u00e9ralement utilis\u00e9s pour r\u00e9gler l'\u00e9paisseur de la jauge, avec la barre d'encre pour v\u00e9rifier si le contact entre les rouleaux encreurs et la plaque d'impression est appropri\u00e9. Si le r\u00e9glage n'est pas correct ou si le temps d'encrage du rouleau encreur n'est pas adapt\u00e9, il y aura une barre d'encre, un front l\u00e9ger puis profond ou un front profond puis l\u00e9ger, une ombre lourde, une plaque fleurie et d'autres ph\u00e9nom\u00e8nes. Les rouleaux en caoutchouc sont sujets au vieillissement thermique, ce qui entra\u00eene un durcissement de la surface, des craquelures, un d\u00e9collement, et affecte le transfert de l'encre UV sur la plaque d'impression. Par cons\u00e9quent, au cours du processus d'impression, il convient de remplacer en temps utile les rouleaux d'encre vieillis, durcis, fissur\u00e9s, d\u00e9coll\u00e9s et non droits, afin que le transfert de l'encre \u00e0 s\u00e9chage UV soit bon et que l'uniformit\u00e9 de la couleur de l'encre soit garantie.<\/p>\n<p>\u2461 Le rouleau d'eau et le rouleau d'eau, le rouleau d'eau et la pression entre la plaque d'impression d\u00e9pendent \u00e9galement de l'\u00e9paisseur de la jauge n'est pas ajust\u00e9e, le r\u00e9glage de la pression entre eux est bon ou mauvais affecte \u00e9galement directement l'uniformit\u00e9 de la couleur de l'encre du produit. Un mauvais r\u00e9glage entra\u00eenera \u00e9galement l'apparition de barres d'eau, de plaques de p\u00e2te, de salissures, de plaques de fleurs, d'\u00e9mulsion d'encre \u00e0 s\u00e9chage UV et d'autres ph\u00e9nom\u00e8nes. Un rouleau d'eau bien r\u00e9gl\u00e9 ne doit pas renvoyer d'encre de s\u00e9chage UV \u00e0 la surface du rouleau d'eau, maintenir une bonne hydrophilie, un bon transfert d'eau, une alimentation en eau stable et uniforme de la plaque d'impression.<\/p>\n<p>Le blanchet \u2462 dans le processus de reproduction de l'image joue un r\u00f4le dans l'acceptation et le transfert d'une certaine \u00e9paisseur de film d'encre, tous deux exigent qu'il soit facile \u00e0 encrer, mais aussi un bon transfert d'encre. Le tissu en caoutchouc devient collant, dur, \u00e9lastique et ses propri\u00e9t\u00e9s m\u00e9caniques se d\u00e9gradent, ce qui affecte ses performances d'impression en mati\u00e8re de lipophilie et de transfert d'encre \u00e0 s\u00e9chage UV. Par cons\u00e9quent, dans le processus d'utilisation, il convient de choisir une bonne performance du tissu en caoutchouc et de l'utiliser correctement, de pr\u00eater attention \u00e0 l'entretien du tissu en caoutchouc, de prolonger sa dur\u00e9e de vie, de s'assurer de l'uniformit\u00e9 du transfert de l'encre \u00e0 s\u00e9chage UV.<\/p>\n<p>\u2463 La pression entre les trois rouleaux est mesur\u00e9e par un microm\u00e8tre apr\u00e8s avoir appuy\u00e9 sur le fusible. Un mauvais r\u00e9glage entra\u00eenera le glissement du cylindre, augmentant ainsi la friction de la plaque d'impression, ce qui entra\u00eenera l'apparition d'images fant\u00f4mes, d'un vide d'impression trop petit et d'autres ph\u00e9nom\u00e8nes.<\/p>\n<p>2) l'\u00e9quilibre entre l'eau et l'encre<\/p>\n<p>L'impression offset ne peut \u00eatre s\u00e9par\u00e9e de l'eau et de l'huile, trop ou trop peu des deux entra\u00eenera des probl\u00e8mes pour la production, seuls les deux maintiennent un \u00e9quilibre relatif, afin de faire en sorte que l'encre \u00e0 s\u00e9chage UV dans l'impression maintienne une stabilit\u00e9 relative. Les facteurs suivants influencent le d\u00e9s\u00e9quilibre entre l'eau et l'encre.<\/p>\n<p>\u2460 la vitesse d'impression. Les imprimeurs savent que l'augmentation de la vitesse entra\u00eene une augmentation du transfert d'eau et une diminution du taux de transfert de l'encre de s\u00e9chage UV ; la diminution de la vitesse entra\u00eene une augmentation du temps de transfert de l'encre de s\u00e9chage UV et une augmentation du volume de l'encre de s\u00e9chage UV. Il est n\u00e9cessaire d'imprimer plusieurs centaines de feuilles de papier pour atteindre un nouvel \u00e9quilibre, c'est pourquoi le processus d'impression doit \u00eatre maintenu dans la vitesse d'impression de l'\u00e9quilibre.<\/p>\n<p>\u2461 Additifs d'encre de s\u00e9chage UV. Dans le processus d'impression, afin de faciliter l'impression de la force lisse \u00e0 r\u00e9aliser, ajouter une certaine quantit\u00e9 d'additifs d'encre de s\u00e9chage UV pour surmonter les probl\u00e8mes d\u00e9coulant de la viscosit\u00e9 de l'encre de s\u00e9chage UV est trop grande, ajouter des additifs d'encre de s\u00e9chage UV affectera \u00e9galement l'uniformit\u00e9 de la couleur de l'encre. Plus il y a d'additifs, plus l'encre \u00e0 s\u00e9chage UV est fine, le transfert vers la plaque d'impression et la quantit\u00e9 d'encre sur le papier sont insuffisants ; inversement, plus il y a de transfert d'encre. Aujourd'hui, la plupart des projets doivent \u00eatre r\u00e9alis\u00e9s par plusieurs machines, chaque machine devant ajouter la m\u00eame proportion d'additifs, de sorte que la quantit\u00e9 d'additifs pour l'encre \u00e0 s\u00e9chage UV ajout\u00e9e aux donn\u00e9es.<\/p>\n<p>\u2462 machine d'impression \u00e0 l'arr\u00eat. L'arr\u00eat temporaire du processus d'impression se produit souvent, g\u00e9n\u00e9ralement c'est la livraison du papier arr\u00eat\u00e9, avec le rouleau d'eau est toujours en cours d'ex\u00e9cution, avec le rouleau d'eau continue de passer la solution de seau d'eau \u00e0 la plaque d'impression, mais le rouleau de transfert d'eau en raison de la livraison du papier arr\u00eat\u00e9 et automatiquement arr\u00eater, avec le rouleau d'eau sur l'eau est \u00e9galement r\u00e9duite en cons\u00e9quence, UV viscosit\u00e9 de l'encre de s\u00e9chage UV dans le processus de marche \u00e0 vide, mais une augmentation correspondante. \u00c0 ce moment-l\u00e0 et apr\u00e8s l'impression, le recto de quelques feuilles de papier s'assombrit, l'impression d'une douzaine de feuilles de papier s'assombrit et la couleur de l'encre devient lisse. Par cons\u00e9quent, le travail de pr\u00e9paration avant l'impression doit \u00eatre effectu\u00e9 pour minimiser le nombre d'arr\u00eats.<\/p>\n<p>\u2463 Le nettoyage de la plaque d'impression. En frottant la plaque d'impression, la disposition de la plus grande quantit\u00e9 d'eau, la viscosit\u00e9 de l'encre de s\u00e9chage UV affect\u00e9e par l'eau, coupl\u00e9e au nettoyage du blanchet, la quantit\u00e9 d'encre de s\u00e9chage UV augmente lentement, jusqu'\u00e0 ce que des douzaines de feuilles atteignent un \u00e9quilibre plus tard. Par cons\u00e9quent, lorsque la presse \u00e0 imprimer d\u00e9marre, il ne faut pas arroser excessivement la plaque d'impression pour la mouiller, et il faut r\u00e9duire le nombre de fois o\u00f9 l'on lave le blanchet.<\/p>\n<p>\u2464 au cours du processus d'impression, le rouleau d'eau devient de plus en plus sale, s'attache de plus en plus \u00e0 l'encre de s\u00e9chage UV, de mani\u00e8re \u00e0 r\u00e9duire l'eau re\u00e7ue du rouleau de transfert d'eau, ce qui entra\u00eene un d\u00e9s\u00e9quilibre entre l'eau et l'encre. Basse temp\u00e9rature et encre de s\u00e9chage UV \"dure\", difficult\u00e9s de transfert de l'encre de s\u00e9chage UV, la machine doit fonctionner pendant un certain temps apr\u00e8s le s\u00e9chage UV pour \u00e9quilibrer l'encre de s\u00e9chage UV.<\/p>\n<p>3) Autres<\/p>\n<p>\u2460 Avant l'impression, il faut identifier l'\u00e9chantillon, afin de s'assurer que l'uniformit\u00e9 de la couleur de l'encre d'impression et d'autres indicateurs de qualit\u00e9 sont conformes aux exigences de la cl\u00e9, il n'y a pas d'\u00e9chantillon de chaque machine ne peut pas commencer l'impression. Au cours du processus d'impression, il faut faire preuve de trois diligences, \u00e0 savoir un contr\u00f4le diligent de l'\u00e9chantillon, un brassage diligent de l'encre et un contr\u00f4le diligent de l'eau. La couleur de l'encre du lot reste uniforme et stable.<\/p>\n<p>\u2461 dans le processus d'impression, pour des raisons m\u00e9caniques, l'encre de s\u00e9chage UV n'est pas uniforme, par exemple apr\u00e8s les dents du rouleau, les dents de la cha\u00eene mordent de mani\u00e8re in\u00e9gale, l'angle de d\u00e9versement du papier est caus\u00e9 par des images fant\u00f4mes, etc.<\/p>\n<p>\u2462 rencontrer des graphiques c\u00f4te \u00e0 c\u00f4te cette version du livre, le nombre d'impressions est moins, le nombre de feuilles et plus, pour garder chaque impression et entre la feuille d'impression et la feuille d'impression UV l'uniformit\u00e9 de la couleur de l'encre de s\u00e9chage UV ou plus d'op\u00e9rateurs de test. En raison de l'emplacement diff\u00e9rent du motif, il y a un motif d'endroits qui n\u00e9cessitent des quantit\u00e9s d'encre diff\u00e9rentes, souvent juste les dents d'encre ouvertes \u00e0 plat un papier d'impression est termin\u00e9e. Pour maintenir la stabilit\u00e9 de la couleur de l'encre, il convient tout d'abord de classer la plaque d'impression, de placer le motif dans la m\u00eame position, afin d'\u00e9viter de r\u00e9p\u00e9ter constamment le r\u00e9glage des dents de l'encre ; ensuite, la plaque d'impression sur la machine doit \u00eatre r\u00e9gl\u00e9e en fonction du motif au d\u00e9but de l'ouverture des dents de l'encre, tout en jouant la jauge en fonction de l'\u00e9chantillon pour ajuster la quantit\u00e9 d'encre, ce processus sur la plaque de papier pour mettre un peu plus, pour jouer une bonne jauge, la couleur de l'encre sur elle-m\u00eame il n'y a pas de changement ; enfin, ajuster l'encre de s\u00e9chage UV lors de l'ouverture des petites dents, jouer un grand fichier.<\/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.
