Received my product but it was 3 days late due to weather, etc.. But the main point I want to stress here is often times we will receive vinyl shipments from vendors and for some reason or other the vinyl is rolled super tight. I don't understand the logic behind this besides maybe saving a little bit on shipping for smaller package size, not weight. Problem is when I unroll the vinyl tunnels form throughout the length of the sheet (tunnels are when the vinyl separates from the backer causing vertical speed bumps or lines). Rendering the material useless as I need to run it through my plotter and now I cannot. Vinyl stock comes on a 3in core from the manufacturer and should remain on a 3in core through its entire journey. I spent close to $50 on 1 yard of material I can barely use. This must addressed asap. I cannot be the only one having this problem as well. If the vinyl does not need to be die-cut on a plotter its fine but if it does its a definite problem. I have pics to upload but don;t see a place to do that here.. Pls Advise.
