Design Development:
Buyers give a design for printing to print department. Designer develops a design of color wise according to print design sheet. Different colored design print in different film paper.
Screen Preparation:
At first mesh fabric tight with frame and then attach photo emulsion coating and drying. After drying film paper add with screen by light and pressure.
Color Preparation:
All printing pastes whether containing colouring matter or not are known technically as colours.
Colours vary considerably in composition. All printing colours require thickening, for the two-fold object of enabling them to be transferred from colour-box to cloth without loss and to prevent them from running or spreading beyond the limits of the pattern.
