Light sources andmetamerism

1.1 Standard colors in SWS color card

D65 is our implied light source, generally refers to the outside light in the shade in a sunny day. Also can use other light source like TL84 CWF, etc.according to clients' requirements.
There is color difference between sample fabric and bulk fabric, we recommend customer toprovide bulk fabric to dye bulk zipper tape, and the color swatch should be at least 4cm.
Please try to use TCX rather than TPX and don't use glisten fabrics or change color's fabrics.

1.2 The way to Minimize the Color Difference problem due to Metamerism

Please use D65 light source for all the standard colors selected from SWS Color Card; When light sources other than D65 (such as CWF, TL84, U3000, INCA.etc.) is used, please specify for DM (Dye-to-match) under the specific light source for color approval.
(Note: For DTM (Dye-to-match) processing, customers are advised to submit fabrics with size over 3cm x3cm for high accuracy on color searching and assessment.)
