The last but not least element of your poster design is the use of images and graphics. Images and graphics can add visual interest, support your message, and create impact for your poster. Images can be photos, illustrations, or icons that represent your topic, theme, or brand. Graphics can be shapes, lines, or patterns that add texture, movement, or direction to your poster. When using images and graphics, you need to consider the following factors: quality, size, alignment, and copyright. Quality will make your images and graphics sharp and clear. Size will make your images and graphics fit your poster and avoid distortion. Alignment will make your images and graphics align with your text and grid. Copyright will make your images and graphics legal and ethical.
By following these key design elements, you can create a poster that will stand out from the crowd and achieve your desired results. Remember to keep your poster simple, clear, and focused on your main message. And don't forget to have fun and be creative!
