Web1 mei 2024 · While traditional printmaking techniques include woodcut, etching, engraving, lithography, and screen printing (Serigraphy); modern techniques have extended to include spray painting, encaustic and gelatin printmaking. Printmaking is utilized by numerous artists today. Printing performance depends on how you prepare the prototype/grid (or matrix). Webetching time is 2 min. Figure 2 shows the SEM images of the etching profiles corresponding to various mask materials. The depths of the trenches were 3.9, 3.8, 3.7 and 3.5 μm, the widths at the half depth were ≈ 185, 200, 190 and 205 nm, for polymer, Cr, SiO 2 and Cr-on-polymer masks, respectively. The slightly
