Quality Assurance & Lab Testing Standards
Eliminating press downtime, blanket dusting, and ink smudging through rigorous batch sampling, calibrated digital micrometer audits, and standardized laboratory verification.
ISO Calibrated Digital Micrometer & Spectrophotometer
Four-Stage Quality Control Protocol
Every imported shipment undergoes four distinct inspection phases before release to clients or warehouse buffer bays:
Factory QA certificates cross-checked with L/C specs.
Container seal integrity, humidity levels, and roll core check.
GSM tolerance, Cobb 60 absorption, tear & burst indexes.
High-speed test prints to confirm zero blanket dusting.
Physical & Substance Calibration
- GSM & Caliper Uniformity: Digital micrometer verification ensuring strict adherence to ±2 g/m² tolerance.
- Moisture Content Calibration: Controlled strictly between 4.0% - 6.0% to prevent curl and edge-waving during humidity fluctuations.
- Tensile & Tear Resistance: High Machine Direction (MD) & Cross Direction (CD) ratings guaranteeing non-stop high-speed rotary printing.
Surface & Optical Properties
- ISO Brightness Spectrometry: Verified spectrophotometer readings up to 104% whiteness on office papers.
- Cobb Sizing (Water Absorption): Controlled liquid penetration for razor-sharp multi-color offset dot reproduction.
- Bendtsen Roughness & Smoothness: Calibrated micro-finish preventing linting and blanket buildup.
Our In-House Testing Equipment & Calibrated Devices
Digital Micrometer Caliper
Measures exact paper thickness (micron) & caliper density.
Spectrophotometer
