Flattening paper is a technique used in fine arts to flatten watercolor papers that have buckled or become distorted due to the application of water-borne media, such as watercolors or acrylics. The process typically involves creating a "paper press" using blotting paper, paper towels, and weights to absorb moisture and apply pressure to the paper. The goal is to flatten the paper without damaging the artwork. The technique is relevant to Golden Artist Colors as it can be applied to papers used with their products, such as Qor Watercolors.

It's worth noting that the technique may not completely eliminate the possibility of future buckling, as paper can respond to ambient moisture. Additionally, the process might reduce the surface texture visible on certain watercolor papers. (Source ID: 5)
It's also important to test the paper and the technique before applying it to an actual artwork, and to be careful when handling the paper to avoid damaging it. (Source IDs: 2, 6)
Overall, flattening paper is a useful technique for fine artists working with water-borne media, and can help to achieve a smooth and flat surface for their artwork.
