Hey Diogo, any 100lb smooth Bristol paper will work just fine for the the inking coursework. Once you get to know how the 100lb paper responds to various inking techniques you can experiment with heavier weight papers, and different surfaces to achieve different results.

I have an affiliate link below for Strathmore 300 Bristol 100lb paper, 11x17 is standard comic art size, tape bound or board bound option doesn’t matter much, tape bound is cheaper, David Finch seems to prefer Smooth, Jim Lee prefers Vellum texture, all available below. https://amzn.to/3rwHDJm No worries, I got you man. You don’t need 300lb, which does exist but it’s overkill for this , especially at this stage. Strathmore “300 series” Bristol will be perfect this. It’s 100lb/260gsm, it loves ink, and it’s affordable. If you want to splurge on 300lb paper that is out there like Arches, Legion, Canson, and Strathmore all make 300lb variants. They cost more, and just aren’t necessary, I don’t know why Stan is recommending at this point other than it is technically much stronger paper. Maybe if you absolutely flooded your 100lb with ink there could be an issue, but very unlikely. Any other questions just ask.
