Having issues of parts of my designs "disappearing" when toggling from Normal to Preview Screen Modes. Everything is intact when in Normal Screen Mode. However, certain shapes/lines/type/images will not be visible in Preview Screen Mode or exporting of any kind.
Please help if you have any insight - this is driving me crazy!
Sounds most likely that they are on a non-printing layer or have been set not to print at the object level in the Attributes panel. The other possibility is they are using a blending mode that would cause them to disappear against a background, or they might be white objects created in Illustrator which allows the overprinting of White if the color was changed from something else set to overprint (ID is smart enough not to do that).
