    That’s what happens with thermal printheads that you heat up.
    To get short runs well, replace all printheads and run 5-10 feet ahead of your wrap job.

    My printheads haven't done a lot of work at all. I thought about changing printheads but literally they are less than few months old

    First problem is your assumption that what you see on the screen is what will print. Unless you have your printer and monitor calibrated perfectly together, and even then, you will never get them to appear exactly the same. That being said, it's all down to the profile and settings on your printer, the material, temperature, humidity, etc. Books could be written (and have been) on color management.
