Approve vegan leather by both physical sample and digital color: use the physical sample as the final reference for surface, grain, hand feel, thickness, and backing, while using digital color for fast screening and production communication. Digital color alone cannot confirm the material’s complete appearance or performance.
Digital color is useful for early selection, color comparison, and communication between buyers, designers, and suppliers. It does not fully represent the physical material. Screen settings, lighting conditions, surface finish, grain structure, and backing can affect the way PVC and PU synthetic leather appears in use.
The physical sample should serve as the approval reference for production. It allows the buyer to assess the material’s actual surface appearance, grain, hand feel, thickness, width, backing, and functional properties. The product specification supports thickness from 0.7 to 1.3 mm, customizable according to requirements, with a width of 54/55 inches and knitted, woven, or non-woven backing options.
For color approval, the digital color should remain attached to the physical sample as a communication reference. The physical sample should identify the approved color, grain, surface finish, thickness, backing, and any requested performance requirements. This combined record reduces ambiguity when color matching and production inspection are performed.
Quality inspection for this sofa upholstery leather includes raw material inspection, color matching confirmation, production process inspection, laboratory testing, finished product inspection, and pre-shipment inspection. Depending on customer requirements, inspection can cover thickness, width, color consistency, surface appearance, abrasion resistance, tensile strength, peeling strength, scratch resistance, and flame-retardant performance.
The approval sequence should be documented as a material control process. Select the initial color digitally, request or review the physical sample, compare the sample with the intended application, confirm the specification, and retain the approved sample for production and shipment inspection. Any later change in color, grain, thickness, surface finish, or backing should be reviewed against the approved reference.

| Approval Method | Best Use | What It Confirms | Limitations |
|---|---|---|---|
| Digital color only | Initial color screening and rapid communication | Approximate color direction and design intent | Does not fully confirm physical appearance, hand feel, grain, thickness, backing, or performance |
| Physical sample only | Final material assessment | Actual surface, color appearance, grain, hand feel, specification, and sample-level performance | Less convenient for rapid remote comparison and early-stage selection |
| Digital color plus physical sample | Production approval for sofa and furniture upholstery | Fast color communication combined with a physical production reference | Requires accurate recordkeeping and sample retention |
| Physical sample plus inspection records | Bulk-order quality control | Approved material reference and documented inspection criteria | Inspection requirements must be agreed before production |
Should the physical sample or digital color control the final approval?
The physical sample should control the final material approval because it represents the actual surface, grain, hand feel, thickness, width, and backing. The digital color should remain as a supporting reference for communication and color matching.
What should be checked on a physical sample of sofa upholstery leather?
Check color consistency, surface appearance, grain, hand feel, thickness, width, backing, abrasion resistance, scratch resistance, waterproofing, stain resistance, easy cleaning, and any requested flame-retardant performance. The required inspection items should be specified before production.
Can digital color be used for a customized PVC or PU leather order?
Yes. Digital color can support initial selection and customized color development, but the final approval should include a physical sample. The approved record should identify color, grain, surface finish, thickness, backing, and applicable performance requirements.
