Paul, With the Multihead BO 1.5 picoliter printing there should be more influence of dotgain by changing paper coating batches and air humidity. First of all its ratio between dot surface and total dot circumference shows changes faster and the black ink has little transparency so its dotgain will have a high density while the spots from where there ink migrated will not become more transparent either. Quite a difference to large dots with diluted inks where the lower dotgain and more ink transparency dampens dotgain influences (but affects detail contrast). I thought way back when we discussed this in theory that it could be a problem. I wonder what it is in practice. At the same time the small black dots give the graphic qualities Clayton liked: paper color less filtered overall, ink color hardly visible, high detail contrast. An interesting advantage could be the very low use of ink and by that of inkmedia so reducing outgassing to a minimum when framed.
