slice&dice 2,450 Posted March 31, 2015 Are these the lyrics to a song? (sung to the tune of "Oh, Susanna") Or are you a S I G N maker? All vinyl must be applied at surface temps of around 62* or more, from what I understand. The exception to this is when using RapidTac II application fluid. 1 Share this post Link to post Share on other sites
Wildgoose 4,200 Posted March 31, 2015 I use High Tack paper most of the time. Oracal/Orafol 651 is a great product and far superior to the GS material. There are a few peculiarities that you have to get used to but once you do it's as easy as you can find. Probably the biggest issue people who aren't used to run into with 651 is that it tends to be a little harder to get up off the carrier than some other products. This makes for easier cut and weed (in my opinion) but can be trickier sometimes with med tack app tape. You don't need special app tape for it like you do with the 631 indoor but I recommend high tack. There are some video's out there that also have some hints of other techniques (lift the carrier up off the back with the vinyl face down or run the vinyl over a sharp edged shelve just before application) that also help but are not always something you can do in every situation. I use a LOT of 651 and it is a real nice product for flat applications and hold up fantastic. If I do vehicles I step up to the 751 cast vinyl. If it has a lot of uneven surface or tons of rivets then you might even want to go clear up to 951 but I rarely have needed to. I also cut a decent amount of GS vinyl but the quality just isn't there for things I am selling to people. There are specific applications that I am ok with using it on but they are limited. The cost difference between GS and 651 just isn't enough of a savings to justify it to for my customers. I did two or three signs with GS early on for some friends and was surprised by the amount of shrink that happened after they had been up a while in the sun. 651 is a little stiffer and thinner and doesn't seem to shrink as bad.

idahospudgal 4 Posted March 31, 2015 I always use 651 for indoor use and 751 for outdoor use. In the 8 years I have been in business I have never had to replace a sign. I have been so happy with it that I have never shopped around. Share this post Link to post Share on other sites

So the last roll of your year's stock didn't work too well. Is it possible that it was too old? Vinyl does have a shelf life. Maybe you should think about ordering twice a year so that your stock doesn't get old. Share this post Link to post Share on other sites

jeremySI 18 Posted April 3, 2015 I dunno, but in my order I placed last week to start my stock of vinyl getting back into this i ordered white and black in greenstar to try em out. Just did something in black last night and that stuff weeded like crap, lifts from the backing super super easy. I will pay the extra few bucks and stick with my tried and true oracal 651 1 Share this post Link to post Share on other sites
