Signlab exporting pdf and white turns to pink dots

Im having issues when exporting pdf and when they print the whites sometimes have pink dots that fill the white. Signlab 9.1. Had this happen a few years ago and cant remember what the deal was.

Figured it out. The white color I was printing in signlab was 255 255 255 and when I did one profile it would make pink dots. Easy fix just changed it to 0 0 0 0
