The ZIG Opaque Pens are specialty markers that contain dark red opaque ink which will absorb ultraviolet light and prevent it from being exposed from a negative image.
Perfect for re-touching film negatives or plates when there is a flaw to be fixed or transparent areas to cover that you donít want to be seen in the actual print. The ink will not crack or peel after drying. Also suitable for use on plastic, glass, and metal.
Great for use in fields like screen printing, photography, and publishing!
