Paper for greetings cards
That's correct - I am in Australia Red River would be expensive to import. I was hoping there would be a more international brand like Epson, Canon etc who had an appropriate paper.
Are there any other suggestions?
Any C1S (coated one side), non-RC (resin coated, read plastic coated) paper should work fine, as long as it is smooth enough to write on. Most standard glossy and semi-glossy (lustre, satin, pearl) papers are resin coated and very difficult to write on. You would have much more luck with fine art papers.
I have seen some Museo papers available in Aus, and they do prescored cards.
I have used Inkpress Duo 80 Matte 80 (215 gsm), which also comes in prescored cards. It is a bit flimsy, but even though it is C2S, writing on it hasn't been a problem - I don't know about Aus availability.
Both Canson and Hahnemühle do smooth matte fine art papers in the 220 gsm range, but I haven’t tried them for card stock.
I think, if you look, there will be a lot available in matte (mat, matt), but you will be lucky to find something with a gloss or semi-glossy surface on one side, except for Red River. Red River must get their stock from somewhere, because they don't make paper.
