The bleed of one color into another is detrimental to perceived print quality of color-printed images, and is one of the problems encountered in ink-jet color printing. Rapid absorption of ink dye and vehicle into the paper acts to prevent coalescence of color droplets, but too strong an absorption of the vehicle along the paper fibers causes spreading and feathering of the image boundary. The process is therefore very delicate and sensitive to the physical and chemical characteristics of the paper surface. In this work, color bleed of characters printed on experimental sheets by an HP 500C DeskJet printer was measured quantitatively by image analysis. The effects of variation of internal sizing on color bleed and color optical density were measured, as well as effects resulting from surface treatments with different levels of starch and polymeric surface size. Results were compared with analogous measurements for printing without an adjacent color, and also for black ink printing on the same paper. The level of starch in the surface treatment was most important in controlling color bleed, whereas surface size was most helpful in preventing image spread in black ink printing, and in increasing the optical density of both black and composite black images.
