"processing conditions manipulated printing films force molecules to adopt different structures, ink evaporates depending on printing speed locking assembly into different stages... slow forces polymers assemble into liquid crystals before film forms, for better stability/ efficiency distinguished from cells random aggregation pathways... further manipulation for either achiral, which is an improvement, or chiral, which is best"
