Als Punktzuwachs\/T\u00f3nus\u00e9rt\u00e9k n\u00f6veked\u00e9s<\/a> (engl. Dotgain oder Tonal Value Increase) bezeichnet man den Unterschied zwischen den Rastertonwerten in der Vorlage und den Rastertonwerten im Druck. Dieser Unterschied ist Drucktechnisch bedingt.<\/p>\n

A t\u00f3nus\u00e9rt\u00e9k-n\u00f6vel\u00e9s vagy t\u00f3nus\u00e9rt\u00e9k-n\u00f6vel\u00e9s<\/a> (TWZ) a nyomdatechnik\u00e1ban haszn\u00e1lt kifejez\u00e9s, amely a nyomtat\u00e1si folyamat sor\u00e1n a nyomtat\u00e1si sablon t\u00f3nus\u00e9rt\u00e9keinek v\u00e1ltoz\u00e1s\u00e1t \u00edrja le. A nyomtatott k\u00e9pet alkot\u00f3 f\u00e9lt\u00f3nuspontok a nyomtat\u00e1si folyamat sor\u00e1n megnagyobbodnak, ami s\u00f6t\u00e9tebb nyomtatott k\u00e9pet eredm\u00e9nyez.<\/p>\n

A pontszer\u0171 er\u0151s\u00f6d\u00e9s m\u00e9rt\u00e9ke k\u00fcl\u00f6nb\u00f6z\u0151 t\u00e9nyez\u0151kt\u0151l f\u00fcgg, p\u00e9ld\u00e1ul az alkalmazott nyomtat\u00e1si elj\u00e1r\u00e1st\u00f3l, a pap\u00edrt\u00edpust\u00f3l \u00e9s a hordoz\u00f3 vastags\u00e1g\u00e1t\u00f3l. \u00c1ltal\u00e1ban a ponter\u0151s\u00edt\u00e9s 10 \u00e9s 20 % k\u00f6z\u00f6tt van. Ezt pr\u00f3banyomatokkal \u00e9s kalibr\u00e1l\u00e1ssal lehet meghat\u00e1rozni a lehet\u0151 legpontosabb t\u00f3nus\u00e9rt\u00e9k-reprodukci\u00f3 biztos\u00edt\u00e1sa \u00e9rdek\u00e9ben.<\/p>\n

A t\u00f3nus\u00e9rt\u00e9kek helyes be\u00e1ll\u00edt\u00e1sa biztos\u00edtja, hogy a nyomtatott k\u00e9p a k\u00edv\u00e1nt sz\u00ednt\u00f3nus\u00fa \u00e9s f\u00e9nyerej\u0171 legyen.<\/p>\n

P\u00e9ld\u00e1ul a 18% t\u00f3nus\u00e9rt\u00e9k-n\u00f6veked\u00e9s azt jelenti, hogy a nyomtatott k\u00e9p t\u00f3nus\u00e9rt\u00e9kei 18%-vel n\u0151nek az eredeti k\u00e9phez k\u00e9pest. Ez az \u00e9rt\u00e9k azt jelzi, hogy mennyivel s\u00f6t\u00e9tebbek a t\u00f3nus\u00e9rt\u00e9kek a nyomtat\u00e1sban a k\u00e9p digit\u00e1lis v\u00e1ltozat\u00e1hoz k\u00e9pest.<\/p>\n
