Intermediate vinyls have certainly improved from when they were introduced into the sign industry back in the 1980's. Now, most intermediates are glossier and last longer, but this doesn't mean they have replaced high performance vinyls. We continue to sell a lot of high performance vinyls because they are more conformable to uneven surfaces; they shrink less and don't fade as fast. Also, there are usually a lot more colors available in high performance vinyl because the manufacturer can run smaller batches of cast high performance vinyls vs calendered intermediate vinyls. If you want to offer your customer a high quality sign with the longest vinyl life possible, it is important to choose high performance vinyl instead of intermediate vinyl.
