<p>A method, apparatus, and computer program product, for forming an addressable array (10) of chemical moieties on a substrate. The method may include, for each of multiple locations (16) on the substrate, depositing a reagent drop set during a cycle so as to attach a corresponding moiety for that location. This may be repeated as required, until the addressable array (10) is formed. Test location (250) are also formed by depositing drops from dispensers in a manner which can facilitate detection of dispenser errors. <IMAGE></p> |
