摘要： Regular-size white cells are expanded in advance to adjust a boundary between black cells and the white cells before a printing operation is performed. Shrinkage of black cells occurs in the region where the expanded white cells overhang over the neighboring black cells. No shrinkage of the black cells occurs in the boundary between two black cells which are located next to each other. A region where one white cell overhangs over another white cell remains white. This is simply realized by outputting 0 for the region where the white dot (0) and the black dot (1) are overlapped and by outputting 0 for the region where two white dots (0) are overlapped. By shrinking the black cells beforehand in this manner, the overhang of the black cells over the while cells is reduced or completely eliminated when they grow fat through the data reading performed by facsimile or copying machines.

摘要翻译： 在执行打印操作之前，预先扩展规则尺寸的白色单元以调整黑色单元和白色单元之间的边界。 黑色细胞的收缩发生在扩张的白细胞突出在相邻黑细胞上的区域中。 在彼此相邻的两个黑色电池之间的边界处不发生黑色电池的收缩。 一个白色细胞悬挂在另一个白色细胞上的区域保持白色。 这通过对于白点（0）和黑点（1）重叠的区域输出0而简单地实现，并且对于两个白点（0）重叠的区域输出0。 通过以这种方式预先收缩黑色细胞，当通过传真机或复印机进行的数据读取，黑色细胞在同时细胞上的突出被减少或完全消除。
