For Acrylic print the Max size is 96 inches by 60 inches.
Yes our Acrylic print is waterproof, we are using UV cured ink technology and this process is water resistant. The only thing you have to note is that the Back Frame mounting option is based on wood and is not guaranteed to last long on a humid environment, we would suggest to use metal pieces stand off as a mounting option or the acrylic sheet only.
For the most vibrant impact, our acrylic prints comes with a glossy finished and has glare. Based on customer feedback, the test we have done on non-glare acrylic support didn't render justice to most images. due to a lack of color gammut and rendering. We suggest to look for our White Metal Print! It will absorb light and will have no glare and provide a very detailed print and same mounting options as acrylic.
