I've been given several envelopes of unknown double weight glossy B+W paper. No external packaging, no instruction sheets inside the envelopes. Three foil envelopes, two plastic envelopes, two fold overs - I'm guessing the last two are Orwo. My plan is to use a small strip to find max black, then print a 21 step tablet and count how many steps to try and guess the paper grade. Is there a better way, and how may steps should I expect for say a grade 3 or a grade 2?
