How can I reduce ghosting during the screen-printing process?


One key to minimizing ghost images is to utilize high-tension screens. Lower-tensioned screens will not reclaim as easily. Imagine trying to remove ink from a draped cloth, such as a curtain. When the force of the pressure washer is applied, the curtain simply moves away from the force of the water and has little effect to the ink on the fabric. Now imagine smearing ink onto a steel post and applying the pressure washer. The ink is blown away as the post is a solid object, making the ink easy to remove. The same theory applies to a low-tension screen versus a high-tension screen. High-tension screens also minimize chemical consumption in the reclaiming and degreasing process when used in conjunction with a 2,000-plus PSI pressure washer.
