Cmyk alternatives, bambu has sold out

Hi, I was wanting to try my first lithophane prints (my mum had a massive stroke in April now in a nursing home so i hope to get some lithophanes of the dogs shes had over the years) but i went to order the filament and bambu doesnt have any left

Having never done a priny like that I'm looking for something thats as close to bambus default settings or a recommended set of filaments and settings
