Patent Searching and Data


Title:
擬似汚れ付着パターン生成方法および光検査用ディスク
Document Type and Number:
Japanese Patent JP5427413
Kind Code:
B2
Abstract:
There is provided a technique for generating a pseudo modification state pattern wherein a printing dot is reliably present in a BD spot with a stable total area ratio, and the transmissivity can be adjusted. A distribution pattern for printing is generated by processors (102a, 102b, 102c). The processor (102a) uses a computer (100) to draw a predetermined number of dot images in an area having a preset size assumed on a disk. The processor (102b) searches an area where no dot images are distributed. The processor (102c) adds and draws the dot images in the detected area where no dot images are distributed. This distribution pattern (200) is used for forming a printing master of a printing machine (140), and a pseudo fingerprint pattern (20a), which is a type of the pseudo modification state pattern, is printed on the surface area (11) of a disk (10), thereby forming the disk (10) for testing.
