The addition of colour to this Shell etching by way of a second colour plate has enhanced the image.
Still experimenting, however.
I used a clear Perspex sheet the same size as the etched copper plate for the application of the colour.
I rolled, reduced colour water based Akua ink onto the plastic plate and placed it over the etched shell plate. Because I could see through the reduced colour on the plate, I wiped away the ink, in parts... hence the white areas. That created my colour plate to print first.
Using my registration on the press, I printed the colour plate on dampened paper.
I then inked up the copper etched shell with oil based black ink.
Using the same registration, I printed the black by placing the already printed yellow brown printed paper on top of the face up inked copper shell etched plate.
I think the white sections are too regular so I hope to remedy that if I decide to produce a small edition of this image.
Wiping back will have to be consistent with an edition of course
