Kertas kerja ini membentangkan kaedah baharu mereka bentuk matriks dither berdasarkan penyepuhlindapan simulasi. Matriks dither yang diperolehi (skrin halftone/topeng) adalah sesuai untuk percetakan akhbar. Disebabkan beberapa sebab fizikal, halftoning untuk percetakan akhbar adalah lebih sukar daripada halftoning untuk paparan elektronik, atau pencetak ink-jet. Walaupun saringan stochastic dispersed-dot (yang dipanggil FM-screening) adalah salah satu penyelesaian terbaik untuk halftoning, itu tidak sesuai untuk percetakan akhbar. Sebaliknya, saringan titik berkelompok berkala klasik (yang dipanggil saringan AM) adalah lebih penting dan digunakan secara meluas walaupun sekarang. Kami mengiktiraf kualiti penapisan AM yang tidak menggalakkan, tetapi kami tidak boleh mengabaikan kestabilan produktifnya dalam bahagian percetakan. Matriks dither halftone yang dicadangkan mempunyai corak titik berkelompok aperiodik, dan saiz kelompok boleh dikawal oleh parameter pemberat fungsi kos. Kami akan memperoleh matriks dither yang terdiri daripada titik-titik berkelompok. Beberapa ciri algoritma reka bentuk dan imej separuh ton disiasat secara terperinci. Akibatnya, fakta bahawa matriks dither yang diperolehi adalah lebih baik daripada skrin AM dan setanding dengan skrin FM dalam kualiti visual, dan matriks adalah setanding dengan skrin AM dan lebih baik daripada skrin FM dalam kebolehcetakan akhbar disahkan.

Abstract: This paper presents a new method of designing a dither matrix based on simulated annealing. An obtained dither matrix (halftone screen/mask) is appropriate for press printing. Because of several physical reasons, halftoning for press printing is more difficult than halftoning for electronic displays, or ink-jet printers. Even if stochastic dispersed-dot screening (so-called FM-screening) is one of the best solutions for halftoning, that is not appropriate for press printing. On the other hand, classical periodic clustered-dot screening (so-called AM-screening) is more important and is widely used even now. We recognize unfavorable quality of AM-screening, but we can not ignore its productive stability in printing section. The proposed halftone dither matrix has aperiodic clustered-dot pattern, and size of cluster can be controlled by a weighting parameter of a cost function. We will obtain a dither matrix which consists of clustered-dots. Some characteristics of the design algorithm and halftoned images are investigated in detail. As a result, the fact that an obtained dither matrix is superior to AM-screen and comparable to FM-screen in visual quality, and the matrix is comparable to AM-screen and superior to FM-screen in press printability is confirmed.
