Title: Forming method for halftone
Inventor: SUZUKI YUZURU
IPC: B41J2/52
Filed: 1986-09-25
Abstract: PURPOSE:To obtain the picture of a high quality with a halftone by arranging a threshold so as to obtain the gradations of more than the number of dots constituting a matrix. CONSTITUTION:The pattern of a threshold matrix is selected so that a characteristic lies on the straight line of 45 degree and besides, so that the more number of effective gradations is available. In this case, the number of the effective gradations after gamma correction come to 24 gradations. After the pattern of the threshold matrix is substituted by the information of '0' or '1', it is stored in a pattern memory 2. In this case, because a signal, quantized into 24+1=25 levels in an inputting device 1, said value being left as it is and as the address of the pattern memory 2, the contents of the memory is transferred to an outputting buffer memory 3. Thus, even in the case of the matrix of 4 X 4, the gradations of more than the number of the dots (16) are available through a device with a prescribed recording density.
