Claim:
1. A system for depositing substances onto a deposition surface, comprising: a first contact spotter comprising multiple spotting orifices fed by multiple fluid inlet conduits such that the first contact spotter is capable of depositing multiple spots of different substances onto the deposition surface simultaneously; a second contact spotter comprising a second spotting orifice fed by a second fluid inlet conduit; and a positioning device adapted to alternatively position and seal the first contact spotter and second contact spotter on the deposition surface at an overlapping location, wherein each contact spotter is a continuous flow microspotter, comprising: wherein each continuous flow microspotter is adapted so that fluid flowing through the first conduit and the second conduit is communicated among the first opening, the second opening, and a deposition surface when the spotting orifice is sealed against the deposition surface to form a deposition spot on the deposition surface.
