Today I made a fairly large print (50x61cm) doing crackle intaglio type on one of the three plates.
It's been a long, long time since I tried crackle intaglio type, but for this print I needed one of the plates to look old. I did a test on a small plate which didn't work really well, so I just went ahead and made the large one:)
I exposed my image and developed it, then I brushed on gum arabic. My plate was on a hot plate and when the gum arabic dries quickly it crackles. Then I put it back in the developer. I left it in for 11 minutes - which could have been all right, but note to self: have enough gum arabic on the actual image or you will end up with open bite areas.
Now, since I needed an "old" plate, it worked great with the open bite:)

The plate looks pretty bad
The petg plate got all bulky from being on the hot plate
