Damiano,

I think you mean if this happens after a warm soaking, like for resinotype. 
I don't believe agar swells like gelatin, because you need to rise the 
temperature up to 90°C to dissolve it. However, I will check these days. 
> is it yellowish or it has other "nuances"?
I have a yellowish agar, given me by a biologist, and a perfectly white 
(edible) agar bought in a grocery. But also the yellowish one, once brushed 
on the paper and air dried, is only barely visible but for the shine of the 
sheet.
