When I created an InDesign document (career survey for students to take), then exported as PDF, the PDF shows the document shrunk -- the print and pictures are smaller. This does not happen for my other InDesign documents exported to PDF format.
What is happening? How can I fix this? I need the PDF the same size as the document because the students need the larger print to read.
When you export a pdf out from InDesign it will never change the size (dimensions). But what might happen is that they are resized upon printing. Take care that in the print dialog from Acrobat is scaling set to None.
You might want to set the print setting in the pdf file properties so that no one will print it accidently scaled.
