For best outputs: Sampler: DPM++ 2M Karras Steps: 35, cfg 7, CLIP skip 1. VAE: none required. Pos prompt: this model has two triggers, "T-shirt design" and "Sticker". For t-shirt prints, use "((solid black background))" to make sure the output you get is actually usable to create a print for a tee. for the sticker, "((solid gray background))" so it's guarantee that you can remove the gray area easily to separate it from your sticker. The model is averagely good at creating text and logos in particular, specially about well known pop culture concepts. To achieve, do as follows, for example, "concept art Terminator, Terminator logo". Neg prompt: "painting, drawing, illustration, glitch, deformed, mutated, cross-eyed, ugly, disfigured, text", remove "text" if you plan to create logos. Checkpoint Merge.
