Removing ink from clothes can be a tricky task, because it is a pigment-based stain, which means that the ink particles bond with the fibers of the fabric. In addition, many inks are water-resistant, which means they do not dissolve in water and can be difficult to remove with traditional laundry detergents.
Another reason that ink is difficult to remove is that it can quickly spread and penetrate deep into the fibers of the fabric. This makes it hard to target and remove the stain completely. But there are a few methods that may help:

One method is to use a solution of equal parts water and rubbing alcohol. Apply the solution to the affected area and then blot it with a clean white cloth. Repeat this process until the ink is removed.
Another method is to use hairspray. Spray the hairspray directly onto the ink stain and then blot it with a clean white cloth. Repeat this process until the ink is removed.
A third method is to use a mixture of baking soda and water. Mix a paste using baking soda and water and apply it to the ink stain. Let it sit for a few minutes, then scrub the area with a brush and rinse the clothes with water. Repeat this process until the ink is removed.
It’s important to note that when trying any of these methods, it’s always a good idea to test a small, inconspicuous area of the fabric first to ensure that the method will not cause any damage or discoloration to the fabric. It’s also best to work on the stain as soon as possible as fresh stains are easier to remove than set-in stains.
