For the most part about all I have ever used was IPI, I think. I have read posts over time about the pros and cons of each. The problems I have may be with both companies but just wondering. The biggest problems I have had are as follows. When lasering, the residue builds up on the nose cone so bad that on some jobs I have to pause the machine to clean the build up off to keep it from scratching the plastic. Another thing is the flatness. I even bought a full case of blue/white that was very wavy so it's not just from buying single sheets. I store it all flat but this will not even out even with added weight. Another, when I peel the plastic protective off, I can see ghosting from the film still on the sheet. Not so bad doing nametags but not so good making larger signage. Anyways, just wondering if it was just me or I need to try a different brand. Thanks for any guidance.
