While state-of-the-art methods for predicting the appearance of inkjet-printed objects assume a perfect grid, the printed patterns have an irregular material distribution due to complex spreading behavior. This i rregularity leads to imprecise appearance predictive tools. Here, we\nprop ose a fully differentiable method that models the material spreading behav ior of inkjet printing. We use a differentiable simulator along with a dif ferentiable volume renderer. Then, using an image of only one printed cali bration pattern, we obtain a generalizable material spreading transformati on that can be applied to an input, nominal grid of materials and produce the effective material grid. By taking into account the dynamics of the pr inting process, our method significantly outperforms state of the art 3D p rinting appearance prediction models.\n\nRegistration Category: Full Acces s, Full Access Supporter\n\nLanguage Format: English Language\n\nSession C hair: Lin Lu (Shandong University) URL:https://asia.siggraph.org/2024/program/?id=papers_398&sess=sess127 END:VEVENT END:VCALENDAR
