Abstract

PURPOSE:To obtain a high-quality, clear printing by using a system in which an interpolation using one or plural black dots is made for between adjacent black dots in a letter matrix, but not for the inside corner of the 90 deg. crossing portion of black dot rows. CONSTITUTION:When making an interpolation using black dots for between two black dots adjacent in the direction of line (row), black dot interpolation is performed except for the case where 4 dots adjacent to the two dots in the direction of line (row) are all black dots. For dot K(0,0) between black dot K(-1,-1) and K(+1,+1) adjacent in the slant direction, interpolation is made for the case where two dots between dots K(-1,+1) and K(+1,-1) of equal pitches from the two dots are all white dots, and in case where any (K(-1,+1) for example) alone of the dots K is black dot, interpolation is made except for the case where two dots between the dots K(-1,-3) and K(+3,+1) are all black dots. Also, in case where all of the dots K are black dots, no interpolation is made.
