Why did I create this poster-design LoRA? Because I needed the following:

1.Train it on high-quality commercial posters to make the output more polished and creative.

2.Ensure consistent visuals when using the same style prompts—perfect for creating a series of posters or PPT backgrounds.

3.Maintain the model’s text-generation capabilities while achieving the above two goals.

You may feel that some images lack contrast. That’s because I’m using the Dev or Fast version of the HIdream model, and the CFG value I use is 1. You can increase the contrast by increasing the CFG value, or use the Full model.

Now, anytime I’m working on posters or illustrations, I think of this LoRA.
