STYLES OR TECHNIQUES OF PRINTING
The manner in which printing pattern is produced is referred to as the style of printing. It can be mechanical or chemical operation. The printing techniques:
The choice of printing technique is dependent on the type of fibre/s used in making fabric and the type of dye stuff that works well with the fabric. This is done so that costs are optimised, appearance of design is as best as possible and time taken is as less as possible. Examples,….
- For Cotton fibre tobe dyed with Naphthol dyes, discharge printing is used.
- For Cotton fibre dyed with Reactive dyes, resist printing is used
- For Polyester fibre dyed with Disperse dyes, discharge or resist printing is used.
METHODS OF PRINTING
Methods refer to the equipment used for producing the print. The difference between the methods is the speed with which a design is transferred to the fabric. Each method has its inherent advantages and disadvantages. A careful choice of method to use for printing needs to be made. Methods of Printing:
• Screen – Manual
• Screen – Automatic Flat Bed
• Screen – Rotary
