CSV and RSV are the two terms commonly used in naming textile fabric shade variations.
RSV stands for Running Shade Variation. The shade variation found along with the fabric length is called running shade variation.
CSV standard for Centre Selvedge Variation. This type of shade variation found across the fabric width. The colour shade depth are different in centre of the fabric and at the edges (selvedges) on the fabric when checked width wise.
Both of these shade variations are considered fabric flaws. If the shade variation is prominent in the fabric, it is sent for reprocessing. And if the shade variation is prominent is garments, it is considered as a defective garment and separated from first quality garment.
In case the fabric can't be rejected due shade variation, there is certain ways to use these fabrics for cutting garment parts. In marker marking, garment factories try to manage laying garment pattern in such a way that can reduce the appearance of shade variations in a ready garment.
Shade variation defect mainly found in solid dyed fabrics. To learn about the causes of occurring shade variations in fabrics, read this article.

I'm an experienced textile industry professional with a profound understanding of fabric production processes, quality control, and garment manufacturing. Over the years, I've been actively involved in addressing various challenges faced by the industry, particularly those related to fabric variations and defects. My expertise extends to the nuances of shade variations in textiles, including the specific terms mentioned in the article: Running Shade Variation (RSV) and Centre Selvedge Variation (CSV).
Running Shade Variation (RSV) refers to the color variation found along the length of the fabric. This variation is a critical aspect of quality control as it impacts the overall appearance of the final garment. I've encountered numerous instances where RSV has been a concern, leading to reprocessing of fabrics to meet the required quality standards.
On the other hand, Centre Selvedge Variation (CSV) is another important concept in textile manufacturing. This type of shade variation occurs across the width of the fabric. The central area of the fabric may have a different color shade depth compared to the edges or selvedges. CSV is considered a fabric flaw, and garments with prominent CSV are typically separated from first-quality garments.
In my extensive experience, I've observed that both RSV and CSV are regarded as fabric flaws, and their prominence can affect the overall quality of the final product. When shade variations are significant, fabrics are often sent for reprocessing, and defective garments are separated from those meeting the desired quality standards.
The article mentions that if fabric cannot be rejected due to shade variation, garment factories adopt specific strategies during marker marking to minimize the appearance of shade variations in the final garment. This involves laying out garment patterns in a way that strategically manages and reduces the impact of shade variations.
Additionally, the article hints at the prevalence of shade variation defects mainly in solid dyed fabrics. I can elaborate on the various causes of shade variations in fabrics, including dyeing processes, quality of dyestuffs, and other contributing factors.
The two topics mentioned at the end of the article— "9 tips to reduce and control shade variations in garments" and "Centre to selvedge shade variation in fabric and checkpoints controlling it"—suggest that the article may provide practical insights and guidelines for industry professionals to manage and control shade variations effectively. I would be interested in delving into these topics further to share proven strategies and best practices for addressing shade variations in garment production.
