I am a digital artist new to etching and I have been having one problem, chronically, over the past couple months. Inside my etched lines there are bubbles, and sometimes the lines look almost completely hollow. I am self taught, so it is definitely something I am doing. Can anyone help?
Attached are some pics of the issue, under a magnifying glass.
The bubbles/hollows are in different places each print, so it seems to be an issue not with my plates, but with applying the ink or wetting the paper or with the way I press.
My process is as follows:
prepare the plate. I don't think I need to go into this because i dont think the problem is here.
Ink the plate. I use oil based ink specifically for etching. I work the ink for a while before I use it, apply with a card or a roller, remove all I can with the card, and remove more with circular motions with tarlatan. I have tried both linseed to loosen ink and magcarb to stiffen it and neither helps. What does help is if I leave a TON of ink on, more than I want, but it still happens in places.
I use newsprint for preliminary proofs, and arches 88 specifically for printmaking....weirdly, it comes out better on the newsprint. I soak the newsprint no longer than 5 minutes, or it will tear. I soak arches 88 for about an hour. squeegee, and blot with paper and a rolling pin.
I use presses specifically for printing. Two are automatic and one is manual, same problem on all. I put the plate face up and lay wet, blotted, paper over it. I always go pretty much as tight as I can. Two thick blankets and one thin one.
Thanks for taking the time to read this.
