I strongly suggest that you use the speedball water soluble block printing ink, the homemade glycerin and gelatin printing plate and sulphite drawing paper.
These supplies allow from the easiest learning. They do take some practice and getting used to if you have not used them before. These 3 supplies create a good transfer of ink from brayer, to plate to stencils and to paper.
I hope that you will use these supplies to gain printmaking skills that will last a lifetime.
Once you have developed a deep understanding of the factors that are affecting your impressions, then it is a good time to experiment with other inks, paints, paper, substrates, and plate.
