Genellikle lazer m\u00fcrekkebi olarak bilinen UV yans\u0131t\u0131c\u0131 m\u00fcrekkep, yans\u0131t\u0131c\u0131 (lazer) bask\u0131 i\u00e7in kullan\u0131lan \u00f6zel bir m\u00fcrekkeptir.

Reflektif bask\u0131, \u00f6zel dekoratif etkisini elde etmek i\u00e7in \u0131\u015f\u0131k yans\u0131mas\u0131 prensibini kullan\u0131r. Alt tabaka olarak genellikle alt\u0131n ve g\u00fcm\u00fc\u015f karton, al\u00fcminize film veya ayna paslanmaz \u00e7elik gibi y\u00fcksek \u0131\u015f\u0131k yans\u0131tma \u00f6zelli\u011fine sahip malzemeler kullan\u0131r.<\/p>\n

Mekanik k\u0131r\u0131lma, d\u00f6ner veya d\u00fcz presleme kullan\u0131larak elde edilebilir. D\u00f6ner presleme geni\u015f alanl\u0131, y\u00fcksek hacimli bask\u0131 i\u015fleri i\u00e7in uygunken, d\u00fcz presleme k\u00fc\u00e7\u00fck alanl\u0131, d\u00fc\u015f\u00fck hacimli bask\u0131 i\u015fleri i\u00e7in uygundur.<\/p>\n

Lazer k\u0131r\u0131lma mekanik k\u0131r\u0131lmaya benzer, ancak k\u0131r\u0131lma plakas\u0131 dokusunun olu\u015fumu \u00e7ok daha karma\u015f\u0131kt\u0131r. \u0130lk olarak, bir lazer k\u0131r\u0131lma deseni bilgilerini holografik bir kay\u0131t malzemesine kaydeder ve daha sonra k\u0131r\u0131lma dokusu, insan g\u00f6z\u00fcyle g\u00f6r\u00fclemeyen \u00e7ok yo\u011fun bir tarama olu\u015fturmak i\u00e7in elektroform kullan\u0131larak sert bir metal \u015fablon \u00fczerine \u00e7o\u011falt\u0131l\u0131r ve k\u0131r\u0131lma dokusu deseni alt tabakan\u0131n y\u00fczeyine aktar\u0131l\u0131r ve bas\u0131l\u0131r.

A practical selection route for photoinitiator-related projects<\/h2>\n

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
