The person responsible for reviewing lab dips will then give comments such as “too dark, too red, make lighter, greener” until the standard is achieved.

What are strike offs and lab dips?

A small sample, usually taken from existing fabric, is called a swatch, whilst a larger sample, made as a trial to test print production methods, is called a strike off. For plain-dyed fabrics it is called a lab-dip, and for yarn-dyed fabrics (like stripes and checks), it is called a handloom.

Why we need to develop lab dip sample for bulk production process?

Fabric manufacturers normally give lab dip samples to the buyers for approval before the bulk production of fabric. Generally, lab dip will help to visualize the total fabric color after bulk production. Therefore, lab dip approval from a buyer is essential for an order execution.

What is the main purpose of taking lab dip approval?

The purpose of a lab dip is to give a designer an idea of what the fabric color will look like for manufacturing. That is why a designer’s approval is necessary before bulk manufacturing takes place.
