Oh, I definitely underexpose my cyanotypes then... Thanks for the tip.
Will try it in the weekend...

I also tried to double coat in order to get deeper blues. I got deeper
blues indeed but also much more grain (showing itself only in double
coated sections of the paper - looking like extreme flaking). Does this
phenomenon indicates that the paper suffers from bad sensitizer
reception? What can be done to make the paper more receptive and prevent
the emulsion disperse in the developer?

AFAIK, this is the paper that Demachy was using for his gum prints.
Thank you,
Loris.
