We can make a large variety of posters in many different colors. We use a ProImage XL 3000 Thermal PosterPrinter by Varitronics. This machine can produce a 44″ x 58″ single color banner from one single sheet of 8.5 x 11 paper. The most common size we do is 23″ x 31″. We have a variety of colors to chose from including: Black, Blue, Red, and Neon Pink (this is for outdoor use only). This is best used with text files, images tend to look to blurry.
