I enlarged one of these drawings from my blog at Reproductions. Gonzalo then put the large drawing under the frame, so that he could copy the image with monoprint ink on the silk screen frame. Some of the ink passed through and stained the large Xerox copy:

Some of the waterbased ink dried, making a "mask," and thus prevented ink from passing through, rather than printing. Thus white lines surfaced instead of black lines. Is this a happy accident?
