I work in a prepress dept and I have a customer who has sent me a PDF of their file for printing. I need to place it into InDesign to set it up for output. The black text in the pdf is 100% Black, which is what I want it to be, but when I place the pdf into InDesign, for some unknown reason the black text is changed into a CMYK black with color coming out on all four plates. I am very confused why it would be doing this. Can anyone tell me what can I do to have the black stay 100% black like it is in the pdf and not break out into 4 colors when I place it in InDesign?
