• Complex vector objects must be simplified or flattened (as bitmap)
• InDesign effects such as drop-shadows, glow, special strokes, or transparency may not be fully supported
• Important: Please take note that some colors on the printed version might differ slightly from the online version due to the physical composition of the paper.

• Text should be intact & vector
• No outlines or bitmaps. (You should be able to highlight & copy the text on the PDF file)
