Aadhaar & Voter ID (EPIC) PVC Card Printing: Legal Standards & Technical Alignment

A technical breakdown of ISO 7810 ID-1 card dimensions, photo DPI scaling, and UIDAI security guidelines for printing citizen identity cards.

Target: KeralaTarget: Pan-India

Printing durable PVC smart cards for citizen documents like Aadhaar, Election Voter ID (EPIC), Ayushman Bharat (PM-JAY), and Driving Licenses is a core daily revenue generator for citizen service centers across India.

Standard Dimensional Specifications (ISO 7810 CR80)

Standard PVC cards must strictly adhere to the CR80 form factor: Width: 85.60 mm (3.370 in), Height: 53.98 mm (2.125 in), Corner Radius: 3.18 mm (0.125 in), Thickness: 0.76 mm (30 mil / 300 micron).

Resolution & DPI Scaling

Aadhaar e-PDFs contain vector text alongside compressed JPEG citizen photos. Printing directly without proper DPI scaling results in jagged QR codes and unreadable ghost photos. Pre-processing the document to 300 DPI or 600 DPI ensures that QR verification scanners read the encoded digital signature without lag.

Automated Layout vs Manual Photoshop

Manual Photoshop editing takes 5 to 10 minutes per customer and carries the risk of accidental aspect ratio distortion. Automated cropping software like Bolco PVC Card Auto Crop performs AI boundary extraction and margin alignment in under two seconds.
