A combination to minimize moiré can be determined theoretically or empirically in four-color printing, but it is very difficult to find a combination to minimize moiré in printing using five or more colors. To solve this problem, image data is color-separated into image data corresponding to plural colorant. Multilevel dither processing is performed to the image data corresponding to the plural colorant. At this time, dither matrices having the same screen angle, the same screen ruling, and different threshold setting methods are applied to the respective image data corresponding to dark colorant and light colorant having the same hue and different lightness values.

An optical arrangement for illuminating a surface of a biosensor is described. The biosensor is preferably a sensor having periodic surface grating structure. The arrangement includes a light source generating light, collimating optics for collimating the light from the light source, and first reflecting surface receiving light from the collimating optics and directing incident light onto a surface of the biosensor and a second spatially separated reflecting surface receiving light reflected from the surface of the biosensor.
