[MelOnline]

hey guys! im having trouble exporting my one label design to pdf - i impoted the barcode as a eps file - but when i export to pdf the barcode is missing. there are 5 different labels and all the other are perfectly fine when i export them, its just this one label. i dont understand what the problem is.

Is it a vector .eps file, is it embedded in Illustrator?

Layer set to print?
