When thinking about the design of a professional poster for an advertisement, billboard or announcement, you need to know the basics of this procedure. Posters require a special approach both in design and in print because of their unique nature. People will only catch a glimpse of it as they walk by, so you need to come up with a good design and print it correctly for the poster to catch the eye. While the poster layout may vary depending on the value set, here are some of the fundamentals for designing and printing any kind of poster.
Steps

Step 1. Choose images and colors that attract attention
Your poster should have both brighter colors and a "strong" image that will catch the eye of passers-by. The poster text should contrast with the background so that it is easy to read. If you use more than one color, be consistent. For example, use one color for the heading and another for the body text. It doesn't matter how many images you use, as long as they are captivating and relevant to the text itself. The first thing people pay attention to are images. Therefore, the images you use should arouse interest in people or certain emotions that make them read the text.

Step 2. Create a worthy variation that replicates the qualities listed below
A bold headline, a readable font, and a unique message are three key aspects to creating a memorable experience for your readers. Make the title the largest font used in the poster, usually at least 34 sizes. If you want to use an interesting font, make sure it's easy to read. If your message says the same thing as others, people simply won't pay attention to it and won't remember it. Therefore, your message must be unique, engaging, and emotional in order to create a lasting impression.

Step 3. Keep your design simple
Limit the number of colors, fonts, images and information used so as not to overwhelm the reader. The intricate design will distract him from the message itself. Typically, posters use 2-3 colors and 2-3 fonts and styles. The number of images varies from poster to poster, from one image to an illustration of each section (for example, in a briefing poster). Provide only the most relevant information, usually a title, a description of the event (if applicable), and basic contact information. Basically, the poster should create an impression, not try to cram as much information into people as possible.

Step 4. Connect the professional printing aspects
Borderless four-color printing, good picture resolution and format are essential elements for professional poster printing. Borderless printing means that the poster uses the entire paper space on which it is printed. Four-color printing is used in professional printing to create high-quality print tones, so try to find a company that will print your poster with maximum color depth. … All of your images must be 300 dpi or higher to be pixel-free for use in your poster. When it comes to format, you need to choose a poster size suitable for the placement, suitable for weather conditions or for transportation, and a glossy finish to brighten the images.
