How do you like to use Ilford Cooltone paper?

...I don't think my browser can display their information correctly. I signed up, but the chart is so compressed it is unreadable. Nor do I see the download .pdf option.

Does the information say about how long until there is a visible difference?

I'm not sure what browser you're using. I've had no trouble with that page using Firefox or Edge. In any case, select "all" in the "entries" drop down, then scroll to IDs 285 through 289 for the fiber based tests. Click on the "+" for each individual test. A link to the complete PDF report will appear. Light exposure before unacceptable changes ranged from 21 to <100 megalux hours depending on toning (if any).

Please let me know where I can purchase some new Kodak paper of that type.

I was referring to the old Kodak Polymax in the previous paragraph. Unfortunately, there is no Polymax anymore.
