And this is why we experiment. The only way I have ever printed on a large scale is by hand with a baren (circular tool used to smooth the paper over the inked linoleum). This time I wanted to see if I could print on an actual printing machine (an old type printer) and see if I could get a better print...
Print of first color layer
As you can see, it was not as successful as I had hoped, mostly due to the large size. If I had done this by hand, there would not be any areas than did not get the proper amount of pressure. You can see this on the bottom half of the print (unfortunately on all of them). The good news is that this is the first layer. When I print the second layer, I will do this by hand, and most of the "bad" areas will be covered my the new color. It will likely need to be a two person job, since the print is not perfectly square when I line up the paper.
The linoleum block with very stubborn ink still covering it.
This is how a print should look. Crisp edges and even color.
Not enough pressure on the edge and middle.
Drying prints (with this ink it takes 24 hours)
