I had a customer recently run a job with a ghosting issue. The job has a heavy amount of 4 color process with with a 877 silver boxes in it. The job was also coated with a soft touch coating. The only areas that ghosted was the silver areas. The customer is trying to say it was the four color inks. What could cause this problem. And what could help this from being an issue? The process inks are a VOC of about 15%.
