Print design that are cluttered can be confusing and disorienting. Simple layouts that reflect your message concisely are more likely to catch the viewer's eye - which is the goal of any good printer advertisement.
Its important to keep in mind that large blocks of copy can be difficult for viewers to fully digest and are often ignored. Using single lines of copy or bullet points will encourage readers to read all the important information you are presenting. Copy placement with images is also important. Placing text over busy images can make the text illegible for your audience.
It's also important to keep the message simple while keeping in mind what will appeal to your target customers and remember that ultimately the only reason people are reading your print design material is because they are looking to know what benefits you offer.
Your printed marketing materials are the only remnants of your company that are left behind after a meeting. Make sure they make an impact!
