It is sometimes frustrating when I am printing vinyl stickers because when I go to cut, the lines are a little off due to the warping of the material when drying. I am using an economy calendared vinyl and am wondering if using a cast vinyl would help (although more expensive). Some materials seem to do well and not warp. Others, like a matte poster that we are using, warp quite a bit. Has anyone else experienced this that can offer some insight on how to reduce this?
