Even if clothing accessories have the same color name, there may be slight differences in color, gloss, and texture depending on the production lot and time of receipt. For items that require repeated production and many additional orders, leaving lot information is the starting point for quality control.
Color names alone are not enough
Familiar colors such as black, navy, and beige can appear significantly different depending on the combination of lighting and outer material. Decisions can be made faster when color names, color chips, and actual roll cutting samples are managed together.
Separate lot and quantity upon receipt.
By distinguishing the lot number, receipt date, color, width, and quantity of incoming rolls, you can reduce mix-up during production. Even if it is the same product number, if different lots are mixed in one product, it is better to have separate approval criteria.
Compare the exterior material and lighting.
The difference between the lining and tape is revealed when they overlap with the outer material rather than when they are used alone. Samples are compared under natural light, indoor lighting, and workplace lighting, and transparency and gloss are also checked.
Check baseline samples before reordering
Reproduction involves a side-by-side comparison of previously approved samples and new stock. If the color deviation exceeds the acceptable range, a decision must be made to separate alternative lots or batches prior to cutting.
We use the same notation system as our partners.
Sharing the part number, color code, lot, production order, and approval date in the same format speeds up response to inquiries and claims. It is safer to actually cut and record the information rather than just sending photos.
Practical checklist
- For each roll received, we record the product number, color, lot, and arrival date.
- Overlap with the outer material and compare under natural and indoor lighting.
- Approved for mixing different lots of the same product.
- Compare with existing approved cuts before re-issuing.
- In case of color deviation, separate usage areas and quantities.

FAQ
Can I skip comparing lots if they have the same color code?
Not recommended. Visual deviations may occur due to differences in dyeing and production time, so comparison of actual samples is necessary.
If the lots are different, can I definitely use them?
It depends on product characteristics, placement location, and acceptance criteria. After comparison, if acceptable, there is also a method of separating usage areas within the same product.
