To guide papermakers to forumulate the best performing, but cost effective coatings for their applications, two very large D-optimal designs of experiments have been conducted on a Cylindrical Laboratory Coater on two different LWC basestocks; 6 formulations variables (namely, day/GCC ratio, latex/starch ratio, binder volume, GCC polydispersity, clay platiness and coat weight) and 2 calendering variables (namely, calendering load and temperature) have been varied and more than 50 different resulting formulation and paper end-use properties measured (such as Hercules nad Brookfield viscosities, etc....
