p.20 Magnani Revere: Sadly it seems that the mill that made this paper has gone out of business. Hopefully this paper will be reintroduced by the new owners, but for now only the last remaining stocks are available.
p.50 The last paragraph of Section 5.4 is missing:

You can add restrainer directly to your sensitiser, for example when using NA2. Simply add a few drops to your sensitiser before coating the paper. I keep three small bottles of 10%, 5% and 2% Potassium Dichromate as a sensitiser additive.

p.61 Towards the bottom of the page when talking about Citric Acid clearing agent I wrote:

3% to 15% solutions should be sufficient for most papers.

I should have written:

1% to 3% solutions should be sufficient for most papers.

It is better to be overly cautious with clearing than to risk damage emerging in the future. I use a 3% solution for tough papers like COT320. But 3% is too strong for Buxton and damages the paper fibres, so for this I use 1.5% wbv. Work prints get 5 minutes in each of the three clearing baths. Fine prints get 10 minutes per bath (just to be on the safe side).

p.72 Instead of “60% room humidity (RH)” there should be “60% RH room humidity”.
p.74 Column 2 in Table 4 should be entitled: Relative Humidity (RH) at 20°C.

Noticed a mistake?

Despite an exhaustive review of The Platinum Printing Workshop, some ambiguities and errors slipped through into the final text.  I apologise for any confusion this may have caused.

If you have seen a mistake, or anything is unclear, then please let me know using my email address at the bottom of this page. I will publish relevant corrections and clarifications on this page.
