    Re: margins for alt process prints?

    I will try dampening the paper and using some Tween 20. Thanks. I hope I can get this figured out. I thought glass rod would be the way to go for very even results, and I'm surprised by how...

    I was finding that I could only do one pass. And if that one pass didn't cover evenly across, it was failed. Every time I tried to turn it around and do a second pass, the second pass would be...

    Re: margins for alt process prints?

    I had the paper taped directly to glass. I avoid anything under the paper that might have a texture, as I found this causes unevenness with brush coating.

    Re: margins for alt process prints?

    Re: margins for alt process prints?

    Now that I think about it, I think 11x14 is a good size to go for if you want to stock up and not have to get several sizes. 1/2 of an 11x14 works really well for 5x7 and 1/4 is good for 4x5; so,...

    I prefer to print an 8x10 on 11x14, 5x7 on 8x10, etc... I agree that it makes it much easier to handle and work with, and also less chance of uneven coating in the image area. My experience (always...
