We use the versatile technique of Grazing incidence small angle X‐ray scattering (GISAXS) to investigate the ordering of colloidal polymer films deposited on Silicon substrate by airbrush‐spray coating. A lateral ordering of the polymer colloids is highly desirable as it would open a promising route to generate laterally structured templates and scaffold for the fabrication of ultra‐high density media. The study shows a strong dependency of the film homogeneity on the number of spray cycles and a strong influence of the solvent choice on the film lateral ordering.
