Abstract
An image recording system and method for smoothing printed characters, in particular, for low resolution printers. The image recording system includes a font decoding device, a font generating device and a font sizing device. The font decoding device decodes first font data including first character size information and first luminance (optical density) information. The first luminance information has two gradation levels for printing image data. The font generating device generates second font data including second character size information, which is larger than the first character size, based on the first font data. The font sizing device reduces the font of the second font data to the size of the first character and at the same time converts the first luminance (optical density) information using spatial filters into multiple gradations to reduce printed character jaggedness. Alteratively, the image recording system can use a pattern recognition spatial filter on the first font data to convert the first luminance information into multiple gradations to reduce printed character jaggedness.
