Hey! Here's my letterpress card about celebrating Summer and Holidays! (something that doesn't has greeting card perse but it should!)
Anyway I'll probably make some Christmas greeting cards, Tom, yours are sooo beautiful and original! Love the Christmas tree one =D
I've a little experience with risograph printing and this is similar but I've learnt that letterpress only understands black or white, doesn't have grey values as riso does.
Tom do you know if letterpress allows the use of fluor inks like riso?
EDIT: I printed it in riso! So here's how it came out.
I used fluor pink and yellow inks (the orange is an overlay of both)
