Em compara\u00e7\u00e3o com a tecnologia de impress\u00e3o offset tradicional, a impress\u00e3o offset sem \u00e1gua tem as vantagens de um excelente efeito de impress\u00e3o, maior efici\u00eancia de impress\u00e3o e prote\u00e7\u00e3o ambiental.<\/p>\n<p>3.4.4.1 Caracter\u00edsticas da tecnologia de impress\u00e3o offset sem \u00e1gua<br \/>\n(1) Bom efeito de impress\u00e3o<br \/>\n\u2460 Alta satura\u00e7\u00e3o de cores.

Como a taxa de ganho de pontos \u00e9 pequena, a densidade de impress\u00e3o pode ser aumentada adequadamente para produzir tons de cores n\u00edtidos, imagens de alta resolu\u00e7\u00e3o e alto brilho, texto fino e imagens de precis\u00e3o.<\/p>\n<p>\u2463 Como n\u00e3o \u00e9 usada \u00e1gua, n\u00e3o h\u00e1 necessidade de ajustar o equil\u00edbrio entre \u00e1gua e tinta, e mais substratos podem ser selecionados, como o excelente desempenho em folhas met\u00e1licas, pl\u00e1sticos e filmes que n\u00e3o podem ser impressos pela impress\u00e3o offset convencional.<\/p>\n<p>\u2464 A aus\u00eancia de solu\u00e7\u00e3o de fonte tamb\u00e9m permite a impress\u00e3o sobreposta precisa em impressoras de dupla face, especialmente para impress\u00e3o em papel fino.<\/p>\n<p>(2) Alta velocidade de impress\u00e3o e produtividade<br \/>\nComo a impress\u00e3o offset sem \u00e1gua n\u00e3o precisa ajustar o equil\u00edbrio entre \u00e1gua e tinta durante a impress\u00e3o, o tempo de pr\u00e9-impress\u00e3o \u00e9 40% menor do que o da impress\u00e3o offset tradicional, o consumo de papel de sobreimpress\u00e3o \u00e9 reduzido de 30% a 40% e n\u00e3o \u00e9 usada nenhuma solu\u00e7\u00e3o de fonte de impress\u00e3o. Isso n\u00e3o s\u00f3 economiza tempo e custo de prepara\u00e7\u00e3o da impress\u00e3o, mas tamb\u00e9m permite obter uma produ\u00e7\u00e3o de alta qualidade e alta efici\u00eancia.<\/p>\n<p>(3) Favor\u00e1vel \u00e0 prote\u00e7\u00e3o ambiental<br \/>\nO processo de impress\u00e3o offset sem \u00e1gua n\u00e3o usa a solu\u00e7\u00e3o de fonte offset tradicional que cont\u00e9m solventes vol\u00e1teis, como produtos qu\u00edmicos, e n\u00e3o emite compostos org\u00e2nicos vol\u00e1teis no ar, reduzindo a polui\u00e7\u00e3o ambiental e economizando \u00e1gua.<\/p>\n<p>\u00c9 claro que a impress\u00e3o offset sem \u00e1gua tamb\u00e9m tem suas defici\u00eancias, como a viscosidade da tinta, os requisitos de qualidade do papel e, para garantir que a viscosidade da tinta n\u00e3o seja afetada pela temperatura, \u00e9 necess\u00e1rio configurar o sistema de controle de temperatura, o que aumenta alguns custos.<\/p>\n<p>Atualmente, o uso geral da chapa de impress\u00e3o offset sem \u00e1gua fotossens\u00edvel tradicional, diferentes empresas, diferentes per\u00edodos de desenvolvimento da estrutura da chapa de impress\u00e3o n\u00e3o \u00e9 o mesmo, mas a estrutura geral \u00e9 geralmente dividida em 5 camadas (de dentro para fora): base da chapa, camada inferior (camada adesiva), camada fotogr\u00e1fica pr\u00f3-tinta (camada fotossens\u00edvel), camada de borracha de silicone repelente de tinta e camada protetora.<\/p>\n<p>3.4.4.2 Composi\u00e7\u00e3o estrutural das chapas de impress\u00e3o offset sem \u00e1gua<br \/>\n(1) Base da placa<br \/>\nA base da chapa \u00e9 o corpo de suporte da chapa de impress\u00e3o, que deve ter um certo grau de resist\u00eancia e flexibilidade. A chapa fina de alum\u00ednio \u00e9 usada principalmente; al\u00e9m disso, tamb\u00e9m s\u00e3o usados papel revestido, chapa de liga de alum\u00ednio, chapa de borracha e chapa de pl\u00e1stico ou uma combina\u00e7\u00e3o de v\u00e1rios materiais.<\/p>\n<p>(2) Revestimento inferior<br \/>\nO revestimento inferior \u00e9 a base da placa e a camada fotogr\u00e1fica unidas na camada adesiva, al\u00e9m da fun\u00e7\u00e3o de ades\u00e3o, mas tamb\u00e9m desempenha um papel no isolamento t\u00e9rmico e na press\u00e3o de impress\u00e3o do buffer.<\/p>\n<p>(3) Camada fotogr\u00e1fica<br \/>\nA camada de fotopolimeriza\u00e7\u00e3o, tamb\u00e9m conhecida como camada de convers\u00e3o de luz e calor, com pr\u00f3-tinta, \u00e9 a portadora da imagem impressa, \u00e9 a composi\u00e7\u00e3o central da chapa de impress\u00e3o offset sem \u00e1gua, a camada de fotopolimeriza\u00e7\u00e3o \u00e9 dividida em dois tipos: negativo e positivo.<\/p>\n<p>(4) Camada de borracha de silicone<br \/>\nA tens\u00e3o superficial da borracha de silicone e da tinta \u00e9 maior do que a coes\u00e3o da tinta, portanto, a camada de borracha de silicone pode ser usada como uma camada repelente de tinta da chapa de impress\u00e3o. A borracha de silicone \u00e9 gerada pela rea\u00e7\u00e3o de dialquil polissiloxano e agente de reticula\u00e7\u00e3o.<\/p>\n<p>(5) Camada protetora<br \/>\n\u00c0s vezes, a camada de borracha de silicone \u00e9 revestida com uma camada de filme de poli\u00e9ster ou polipropileno com boa camada protetora de transmiss\u00e3o de luz, o que pode evitar que a placa seja arranhada e melhorar o v\u00e1cuo durante a exposi\u00e7\u00e3o.<\/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>Refer\u00eancias de produtos recomendadas<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/pt\/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\/pt\/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\/pt\/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\/pt\/product\/photoinitiator-cq\/\">CHLUMINIT CQ<\/a>:<\/strong> A direct reference for visible-light and color-sensitive curing discussions.<\/li>\n<\/ul>\n<h3>FAQ para compradores e formuladores<\/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.
