Are you looking for batch-by-batch approval? Or is this your initial 'color approval' to ensure that YOU understand what 'THEY' are looking for.

The first (batch by batch) isn't likely to happen. The second is the norm, and the 'how to do it' will vary by customer.

Hi

I want to do this activity for every batch (batch to batch), not a single time.
Our customer also insists the same. But I’m not sure how to do this.

Actually my requirement is what are the basic test we need to do and how to do(like color values)

Thanks
Vivkrish

Is your customer planning to come on-site to review and approve each batch? Or are they looking to approve YOUR METHOD of evaluating the color?

I suspect it is the latter - to evaluate color match, you need a spectrophotometer (measures color values), as well as a properly illuminated inspection table (visual inspection/evaluation is always critical).

Hi,

Our customer required our evaluation method.

Currently we are ensuring with spectrometer.

I would strongly recommend that you also evaluate your inspectors for color vision - there is a test kit available (a Munsell kit) that can show your inspectors ability to visually discriminate between shades of color, etc.

YOu will also want to do a GR&R on your spectrophotomoter, to ensure that your inspectors/operators are using it correctly.
