Abstract
Sposób przygotowania form do druku offsetowego, w którym to sposobie odczytuje się obraz wielotonalny, dla którego generuje się obraz rastra modulowanego amplitudowo z wieloklastrowymi punktami rastrowymi, po czym obraz rastra utrwala się na formie drukowej, polega na tym, że generuje się obraz rastra modulowanego amplitudowo w ten sposób, że: określa się (301) parametry punktu rastrowego; określa się (302) rozmieszczenie sub-komórek w obrębie punktu rastrowego; dla każdej sub-komórki określa się (303) funkcję tej sub-komórki, która to funkcja określa sekwencję pikseli, wskazującą na kolejność aktywacji pikseli urządzenia w obrębie danej sub-komórki; określa się (304) dla punktu rastrowego funkcję punktu, która to funkcja określa sekwencję sub-komórek, wskazującą na kolejność sub-komórek; po czym dla co najmniej jednej wartości tonalnej z obrazu wielotonalnego generuje się (305) zestaw danych reprezentujących obraz wieloklastrowego punktu rastrowego, określając które piksele urządzenia są aktywowane dla danej wartości tonalnej, zgodnie z funkcjami sub-komórek i funkcją punktu; a następnie generuje się sygnał reprezentujący obraz rastra modulowanego amplitudowo, w którym co najmniej część punktów jest reprezentowana za pomocą wspomnianych obrazów wieloklastrowych punktów rastrowych i utrwala się obraz rastra reprezentowany tym sygnałem na formie drukowej poprzez naświetlenie płyty drukowej promieniem lasera i odzwierciedlenie na płycie obrazu rastra.
