When we think of alternatives to contact (or proximity) printing, laser direct imaging (LOI) comes to mind. However. there are many alternative approaches being looked at. Some are commercial, some were developmental or commercial bUl faded away, and others are altlle conceptual or lab development stage. Laser direct imaging itself offers a variety of different technical approaches.
