Rationale: Screen printing has created a niche by its wide range of applications including packaging and label design, large format printing and special applications. The process also requires less capital for upcoming entrepreneurs. After undergoing the practicals of this course, the student would be able to perform – Multi-colour printing with proper registration; understanding the cloth type, mesh count, calendaring; different types of image carriers & their preparations; printing on different surfaces; etc.
