I recently purchased a UCJV300 for the purpose of being able to print white ink. I have been very disappointed so far. Printing other colors has been fine, but when I do a layered print with white, it cracks on application. We have used the "approved vinyl" to make sure that isn't the issue. I had the tech here yesterday and he agrees that the white is not as conformable for some reason. They are looking into whether it may be a bad batch of ink. Waiting on the results of their investigation. The ink literally flakes off of the media if it has any type of bend in the media. Anyone else had this type of issue?
