Ink rollers are tools used primarily in printing and crafting. They consist of a cylindrical roller covered in a soft material that absorbs ink. When rolled over a surface, they evenly distribute ink, making them ideal for creating clean prints or applying ink to stamps. These rollers are commonly used in various applications, including block printing, rubber stamping, and screen printing. They come in different sizes and materials, allowing users to choose the best option for their specific project. Ink rollers are essential for achieving consistent and professional-looking results in any ink-based endeavor.
