Political signs are made from 4mm corrugated plastic using digital or conventional screen printing as a means to decorate them. Screen Printing is far more durable and superior to digital signs not using laminate. Larger quantities are needed since screen printing requires extra material and labor rescources to setup. Since Screen Printing is ultimately a faster means to get images transfered to surfaces, eventually the price for a superior screen printed sign actully can become cheaper than those digitally printed. Discounts are dependent on variables including sign sizes, color schemes and quantities. Please ask one of our qualified team members, who have over 30 years experienced in the industry, to explain what decoration method is best for you.
