A method for quality assessment in imprint lithography which is based on analyzing the quality of an imprintable layer based on indirect detection of its viscosity. The method comprises imprinting a dedicated test pattern comprising multiple pattern sections, comprising pattern indentations of differing widths and/or depths. The viscosity of the imprintable layer affects how it flows to fill the lithographic imprint pattern, and higher viscosity results in uneven (at a micro or nano scale) layer geometry (i.e. curved or bowed) in each groove or on each ridge of the indentation pattern. This unevenness is detectable upon optical inspection, due to a thin-film interference pattern caused by the passage of light through the uneven imprintable layer surface, and back-reflection from an underlying substrate, this being detectable in captured optical image data. Thus, the viscosity of the imprintable layer is indirectly detectable via capturing optical image data of the test pattern. By using multiple different pattern sections of differing width and depth, a precise quantitative measure of viscosity-related quality can be identified.
