A lot of people think Leonardo ai is very difficult to learn but believe me when I say it’s one of the easiest and accurate ai image generators out there. In this article, I’ll share with you the perfect prompt format that you can use to create trendy t-shirt designs with Leonardo ai.
The prompt I will be showing you is very simple, but I will show you how you can use it to create many different t-shirt design styles.
So, the t-shirt design prompt format is:
Style, text color, words, font, element or image, isolated on a white, black or any other color of background you want,
That’s pretty much it. Now, let me show you how to properly write the prompt in Leonardo ai.
Create the set-up
- First things first, you need to login to the website. If you don’t have an account, you can click here to create one.
- Go to the image generation panel.
- Click on “preset” and choose “Leonardo phoenix”.
- Move to the “prompt enhance” option and turn it off.
- The last setting is not necessary, but I like to change the “image dimension” to 4:5 so it fits the t-shirt print area.
Ai t-shirt design prompt
Using the prompt format, I’ll create a grumpy cat t-shirt design which is very popular at the moment.
Here is the prompt:
Retro groovy style, black text “I hate Mondays”, Bold tall font, a grumpy black cat holding a white mug, isolated on a white background,
One thing you have to remember about making text designs with any ai tool is that you’re not going to get the perfect results all the time. So, you have to generate a couple of times and see what the ai gives you just like a slot machine game.
