Lab Dip or Lab Dye is a small piece of fabric or swatch which is taken from an apparel style, colored to a particular shade. Before bulk production of fabric and garment manufacturing, lab dip approval from the buyer is very essential. There are different types of lab dip shade matching method in garments lab such as tube light matching, sunlight matching, ultraviolet matching, sodium light matching etc. Those methods give different results in different time. Normally merchandisers are follow up this process and lab dip methods are applied as per buyer requirement.
Importance of Lab Dip Approval in Garments:
We all know that the fabric is the main raw material in a garment, therefore; fabric color matching with buyer desired garment is an important task before bulk manufacturing process of garments. 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.
Lab Dip Approval Process in Apparel Industry:
The lab dip is usually made on a small swatch of fabric, which length and width should be 6”X 6″. The apparel lab test unit uses their sample color, particular reference number or Pantone number for every lab swatch to define the color standard. Generally, garments use their color shade as section wise. An example, shade A, B, C, D in 3 to 6 options of a color shade, but lab approval will be better if use minimum four options, therefore, buyers can find an accurate color which is closer to standard with sample color. Some buyers can be recommended for spectrometer and light box to match color. Spectrometer machine finds out of all electrical data and similar color, tone or hue. But this process is very expensive and not user-friendly. On the other hands, light box has special light sources which provide the right environment with options of viewing angles for color matching and comparing with the sample. There are different types of light box in the market, but most of the buyer recommends D-65 and TL-84 light box for shade matching.
