It’s important to consider your target audience. When service companies print a report or presentation for customers, that is usually the only “physical evidence” of the work they charge for, which often runs into hundreds of euros per hour for solicitors, accountants or lawyers.
The cost of the paper itself is just a tiny fraction of the global printing cost, yet the recipient forms a good subconscious impression of the report, simply from the quality of the paper: how much value can you place on that? It is very likely that a more expensive paper will be cheaper in the long run, even without taking into account the positive subliminal messages it sends.
