Re: 3rd layer of gum

That was my guess...but have you found that you have to compensate for this? Longer exposure? More dichromate for that layer?
Or maybe you haven't experienced this on paper...

Because hardened gum is slicker than rough paper?

Hi all...
Why does the 3rd layer of a gum print always develop so quickly, or is subject to washing off so much more quickly than the other layers, whether with sized paper or not...? (regardless of printing order, as well...and these are all the same exposure time, too)
This has happened on several tricolors I've done now...
