Explore PowerPoint templates with professionally designed layouts to create polished, modern, and visually cohesive presentations.
AI is truly revolutionizing the design process, turning any fleeting idea into a visual concept in seconds. For poster design, this is a game-changer. Suddenly, brainstorming a hundred different directions and angles for a poster or a motivational print isn’t a week-long struggle; it’s an afternoon of creative play.
But let’s be real: if you’ve tried designing a poster or flyer, you’ve likely experienced a moment of brain fog. Generating an AI illustration is often a brilliant starting point to a graphic, but it’s rarely what you might call a final, print-ready file.
This AI poster design guide is your bridge. We’ll walk through the entire workflow, from generating your core poster art with a tool like ImageGen, to enhancing it with professional assets from Envato, and finally, finessing it to perfection in Adobe Illustrator.
Whether you’re crafting promotional posters, event marketing materials, or creative art prints, this easy approach keeps your creative process smooth while ensuring you stay professional.
How to design a poster for an event
The process of transforming AI-generated art into a print-ready, professional poster begins by using ImageGen to create stunning base artwork. Then we’ll layer on premium Envato fonts, graphics, and mockups. Finally, we’ll refine the color, resolution, and layout in Adobe Illustrator to guarantee a flawless, print-ready result. So let’s begin!
1. Plan your abstract cubist art poster concept
Before opening ImageGen, let’s establish a clear creative direction. Start by identifying your purpose and audience. Are you creating a poster for an event, an exhibition, or as an art print? This clarity will guide every visual choice you make.
For this project, we’ll cover how to design a poster for an event. Let’s create a poster design for a Cubist art exhibition at a modern gallery. It should feel avant-garde and sophisticated, possibly in a portrait format, to balance visual weight while leaving enough space for key details, such as dates and titles.
The audience consists of art enthusiasts and museum-goers, so the design should resonate with those who appreciate intellectual and abstract visuals.
Gather cubist-style art references from artists like Picasso, Juan Gris, and Albert Gleizes, focusing on their signature styles: fragmented forms, multiple perspectives, and a muted color palette of earthy tones such as ochres, greys, and browns.
Use these references to craft a specific AI art prompt with the keywords: “Cubism, fragmented planes, multiple perspectives, earthy color palette.” Your prompt should deconstruct a classic subject, such as a portrait, into a signature Cubist style.
Once you’ve collected cubist art references and outlined your vision, you’re ready to craft your first prompt in ImageGen.

2. Generate the Cubist artwork in ImageGen
Head over to Envato’s GenAI → Image Gen, which features over 40 selected styles. These built-in styles cover a wide creative spectrum, allowing you to achieve your desired aesthetic in just a few clicks without wrestling with complicated prompts.
To craft Cubist-inspired artwork for the exhibition poster, clarify the composition, style, texture, and atmosphere for your prompt. First, select ‘Auto style’, ‘Portrait orientation’, and the 6-variation set. Then refine and optimize your prompt:
Prompt: “A modern museum illustration inspired by early 20th-century Cubism, an abstract geometric composition featuring fragmented faces, musical instruments, bottles, and architectural forms arranged in a harmonious, balanced layout (Composition) + Rendered with overlapping planes, angular shapes, and multiple perspectives to match Cubist styles (Style) + Add visible brush textures, paper collage effects, and layered transparencies (Texture) + Use a CMYK-friendly palette of muted ochres, terracotta reds, slate blues, grays, ivory, and black, no neon or oversaturated colors. Lighting is soft and diffuse, enhancing the painterly texture. Stylized but sophisticated, ideal for a museum exhibition poster (Atmosphere).”
3. Export the AI image to high resolution
Once you’ve created your perfect poster artwork in ImageGen, export it at a high resolution to maintain sharp print quality. Stay away from low-res web defaults. When your image looks right, tap it and select the Edit icon to open ImageEdit. Then, select Upscale to increase your artwork size by 2× or 4×. After you upgrade, tap “Keep,” then download the final version. Now it’s set for layout and finishing touches in Adobe.
4. Select your Adobe tools for poster design
Select the appropriate Adobe app based on your poster design requirements. For this project, we’ll use Adobe Illustrator, as it excels at creating sharp, scalable graphics. If you’re working with a lot of text and images, then Adobe InDesign is ideal for tidy layouts. If you want to create textures, adjust lighting, or apply photo effects, consider using Adobe Photoshop.
5. Incorporate Envato fonts and graphic assets
Next, find assets from Envato to use in your poster design. For this Cubist-inspired art exhibition design, we’re starting with the Art Exhibition – Flyer & Instagram Set. We can expand the A4 flyer to an A3 poster.
For the text, choose font pairings from Envato’s Font Pairs. For this poster, we’re pairing the Groptika font with Host Grotesk. To bring out the Cubist art theme, add angular, abstract shapes from the Man and Woman Fine Art Vector Illustration set. Download the assets and start designing.
How to set a print-ready canvas using Illustrator
After importing your AI-generated artwork and assets from Envato, start by setting up a print-ready canvas. By following these steps, you’ll give your poster a polished look using Illustrator.
1. Open and check the Document Setup
Open the A4 flyer template downloaded from Envato. Go to File > Document Setup and ensure the Bleed is set to 3 mm on all sides. Then, click OK.
2. Resize the Artboard and scale content to A3
Press Shift-O, then Enter to open Artboard Options. Change the preset from A4 to A3, then click OK. Press Command-A to select all. Hold Shift (proportions) and Alt (scale from center) and drag a corner until your design fills the A3 artboard.
Need more help with sizing and setup? Refer to our Print Graphic Guide for guidance on resolution, bleed, and color settings.
3. Confirm CMYK and Raster Quality
Go to File > Document Color Mode and set it to CMYK. Then click Effect > Document Raster Effects Settings and set Resolution to 300 ppi.
How to refine and export the poster design composition
1. Clear space for new elements
Select the Selection Tool (V) and remove any irrelevant graphics, placeholders, or background shapes to create space for the AI-generated image and new cubist art elements.
2. Set up a grid and guides
Go to View > Rulers (Command-R) and enable Smart Guides (Command-U). Drag out guides to establish margins and align text areas. A modular grid—split vertically and horizontally—adds flexible structure. Lock guides via View > Guides > Lock Guides.
3. Add your AI-generated image
Go to File > Place (Shift-Command-P), select your image, and place it. Use the Selection Tool (V); hold Shift to keep proportions and press Alt to scale from the center. Position the image within the grid and send it behind graphics and text via Object > Arrange > Send Backward. Adjust for balance and adequate negative space.
4. Add typography and establish hierarchy
Type your text to establish hierarchy. Use Groptika for a bold headline. For subheaders, use Host Grotesk at a smaller size and semibold weight. Details should be provided in regular weight for items such as date, time, and venue.
These type choices come from the Envato font collection, which offers paired fonts for cohesive, professional design.
5. Character and Paragraph Styles ***
After adding the text, check spelling, adjust sizes, tweak tracking and line spacing, and use Character and Paragraph Styles for consistency.
6. Align to the grid
Align text and graphics along guides or columns. Use the Align panel for even distribution and spacing. Maintain consistent margins and ensure the layout is aligned.
7. Fine-tune spacing and add graphics
Adjust block and text colors for contrast and align everything to the grid. Add geometric shapes using the Rectangle Tool (M) and abstract cubist art graphics from the selected Envato assets to achieve a cubist art style. Balance the composition.
8. Final check and export
Hide guides via View > Guides > Hide Guides (Command-;). Double-check spelling, fonts, and colors. Save your file. Then File > Export > Export As a PDF/X-4 with 3 mm bleed and Trim Marks on. For digital or social, export JPG/PNG, RGB, 72 ppi.
Here’s our exported result:
9. Preview with Envato mockups
Drop your Cubist art style design into real-world poster mockup templates (such as street billboards, gallery walls, etc.). Open in Photoshop, replace the smart object with your poster, and save.
Poster design pro tips
- Generate multiple ImageGen variations — Experiment with different prompts, art styles, and compositions. Then mix and match the strongest elements from each AI render to create a unique, high-impact poster concept.
- Use Envato’s curated font pairings — Typography can make or break your design. Explore professionally matched typefaces from Envato to instantly elevate your poster’s readability and visual hierarchy.
- Run a quick legibility test — Step back about two meters from your screen or print a draft. If your headline and key event details still stand out clearly, your design passes the distance test.
- Double-check every detail before printing — Ensure your dates, names, and contact info are accurate. A flawless design loses its impact if the essential details are off.
- Set up proper bleed and safe zones — Add at least 3–5mm of bleed to prevent trimming issues and keep important text or logos safely inside margins for professional printing results.
- Use licensed, high-quality fonts and assets — Avoid copyright issues and low-res graphics. Envato offers professionally licensed assets that guarantee both quality and peace of mind.
- Don’t rely entirely on AI-generated images — Treat AI art as your creative foundation. Refine textures, adjust colors, and balance composition in Adobe Illustrator or Photoshop to make your poster truly print-ready.
