The blotter itself could react with most of these reagents. (The why is that most of them are 85%+ Sulfuric Acid - which reacts with almost everything)
Ehrlich doesn't react with paper, but you'd need to check all of the others by extraction / drying / testing rather than applying directly to the blotter.
Edit: This is my testing dish of choice, all you need is a piece of printer paper or a white paper towel underneath for contrast.
