Hi have done it in the past [when kids were tiny!] Couldn't comment on ink - I think we got some from an artsy relative.
we did lino prints for our baby announcement cards with a line drawing of the baby [no-one can really tell if it's "like", can they?!] also a teddy bear a very stylised snowdrop I love looking at other people's landscapes but I know I couldn't do them, they're way too advanced for me!
oh, it's just getting clean lines is not as easy as I'd thought, will take me a couple of goes I'm sure to get the hang of it!
I was just using tempera poster paint as we have some kicking around, will need to get some oil based ink if you can recommend any? and yes, doing it by hand, I have 2 brayers, one for ink, one for the printing
Just buy a basic oil based ink, I did print at uni years ago but couldn't tell you any brands.you will get a much better finish,I would imagine poster paint would spread too much. If you warm the lino on the raidiator or with a hair dryer before cutting it makes it alot easier. Have you looked at Angie Lewin for inspiration,one one my favourites
I use printing ink these inks which are really easy to use, and as they're water-based it's super easy to wash off the lino and rollers. Remember to use really sharp tools, but it is hard work, and tricky getting straight fine lines. Also remember, less ink is best - little bit on the glass/whatever and roll roll roll! If you use too much your lino with slip about, not print evenly, and it will take aaaaages to dry. But when you're up to speed it's so much fun, and so rewarding!
