Yes, seed paper can be printed on both sides. However, printing on both sides may affect the texture of the paper and the visibility of the seeds, especially if the ink coverage is heavy. Keeping some of the seeds visible also adds a lovely visual element to the final product. To ensure the best results, it is recommended to use lighter ink coverage and avoid printing large solid areas on both sides of the seed paper. It is also important to consider the drying time for the ink before handling the printed seed paper to avoid smudging or smearing. Overall, printing on both sides of seed paper is possible, but it requires careful consideration of the design and ink coverage to achieve the desired results.
