Begin by creating the poster design using graphic design software or specialized design tools. Consider the size, orientation, and overall aesthetic of the poster. Incorporate the desired visuals, text, and branding elements.

Ensure that the design has a suitable resolution for printing, typically 300 dots per inch (DPI) or higher, to ensure crisp and clear imagery. Convert the design file to the appropriate file format, such as PDF or TIFF, with the required color profile.

Choose the appropriate paper type for your poster. Consider factors such as durability, finish (glossy, matte, or satin), thickness, and weight. Select a paper that complements your design and aligns with the intended purpose and budget.
