Barcode readability
Decode standard 1D and 2D barcodes and detect unreadable or missing symbols.
Print, inspect and control in one flow
BLC Print Inspection System
Inspect labels as they leave the industrial printer. BLC captures each configured label, checks print and data rules, responds to nonconformance and keeps evidence for traceability.
- 1D & 2D barcodes
- OCR / OCV
- UDI / GS1
- RFID option
Inlineinspection at the point of printing
Up to 1200 dpiCIS acquisition on the B412 model
2.5 ptminimum OCR/OCV font on the B412 model
Up to 180 mmmaximum label width on the B606 model
How BLC works
Stop label defects before they leave the printer
BLC adds a line-scan inspection path to compatible industrial printing workflows without turning quality control into a separate manual station.
Print
The existing application sends the label job to the industrial printer.
Capture
The CIS module acquires the complete label image as it exits.
Evaluate
Software applies the selected barcode, text, image and data rules.
Respond and record
Configured NG actions can pause, alert or signal equipment while results and images are retained.
Inspection capabilities
Configure the checks that match your label risk
Functions are selected according to label design, compliance requirements and production process.
02
Reference barcode grading
Optional ISO 15415/15416-based dynamic grading for process reference, subject to site calibration.
03
OCR and OCV
Verify printed text content or presence, including dates, lots, part numbers and regulated fields.
04
Defect and template checks
Detect missing print, contamination, ribbon wrinkles, broken lines, position shifts and template differences.
05
Serial and database validation
Check duplicate or missing serials, sequencing rules, reference fields and database records.
06
UDI, GS1, RFID and MES
Validate structured barcode content and extend to RFID consistency or production-system integration when required.

Printer compatibility is assessed before configuration
Existing adaptations include selected Zebra ZT/ZE, TSC MH, SATO CL4NX and Epson ColorWorks/TM models. Exact printer, print mode, label stock, speed and mounting conditions must be confirmed for each project.
Model capabilities shown are selection guidance, not a final configuration. Results depend on label material, ribbon, print quality, speed, barcode size, installation and acceptance criteria.
Application examples
Label control across regulated and high-volume manufacturing
Automotive components
Inline inspection helps prevent unreadable or incorrect labels from moving into customer and traceability processes.
Medical devices
UDI, barcode, OCR and print-defect checks can be combined around the approved label format.
New energy
Serial and data validation supports reliable item-level identification at production scale.
Project questions
BLC FAQ
BLC is designed for inline inspection of each configured label passing through the acquisition path. The project must still validate mounting, print mode, minimum label size, speed and exception handling.
The optional module performs dynamic ISO 15415/15416-based grading for process reference. It should not be represented as a substitute for an independently required certified verification method.
Depending on configuration, BLC can pause the printer, activate an alarm, display a software warning or signal external PLC/IO equipment.
Many Zebra, TSC, SATO and Epson models have been adapted. We confirm the exact model, width, print mode, label path and installation space before proposing reuse.
Yes, database comparison, production-system interfaces and external IO can be included. Data fields, interface method and failure recovery are defined per project.
Yes. Richvoice is based in Shanghai, China and supplies BLC print inspection systems for international projects. Start by sending the printer model, sample label or print file, dimensions, speed, barcode size and required checks so we can confirm a test plan.
BLC APPLICATION REVIEW
Evaluate your label and printer
Share the printer model, sample label, dimensions, speed, barcode sizes, OCR fields, UDI/RFID needs and required NG response. We will map them to a suitable BLC model and test plan.
