In this spec, you create a multi-page PDF/X-4A file that contains your entire process from start to finish (dip—including research, planning, ideation, and iteration) concluding with the presentation of your proposed design solution(s). Design thinking should be included at the beginning and asset citation should be included at the end of your combo PDF. The A2ZCpdf file name should use the CFN spec with “-COMBO_MMDDYYb.pdf” at the end of the file name (using the MMDDYYb versioning spec).
TIP: Use Adobe Acrobat Pro’s “Combine Files” feature to merge multiple PDFs/files into one.
