A biocidal film-forming composition, preferably a paint, is disclosed, comprising hydrated lime, alkaline potassium salt, and a non-ionic polyolefinic latex resistant to hydrated-lime induced coagulation and phase separation. The ferroelectric liquid crystal cell includes a reflective portion and a transmissive portion. The algorithm is based on inverting the program data for data being programmed to a cell grouping when a defective cell is detected in the cell grouping. The respective planes to the dot merger unit may include three contone color planes and a bi-level spot plane and the color mask register may be loaded with bits that are selected to split a K plane into C, M, and Y channels for output to a print head without K. Other systems and methods are also provided. Sufficient purge gas is flowed from within the generally enclosed space into the subspace discourage atmospheric contaminates from entering into the subspace.
