GRAPHO METRONIC Product Lines We Repair
Our engineers are trained on the full GRAPHO METRONIC product range. Below are the major product families we service.
ColourControl Series
Real-time colour management and spectrophotometric measurement systems for print quality assurance. Common repairs include sensor calibration drift, display failures, and communication module faults that affect colour matching accuracy.
InkControl Dosing Systems
Automated ink dispensing and viscosity control electronics for flexographic and offset presses. Typical repairs address pump controller failures, pressure transducer malfunctions, and solenoid valve driver board faults.
ProcessControl Modules
Embedded industrial controllers managing print line parameters, speed regulation, and material tension. Repairs commonly involve firmware updates, relay board degradation, and sensor interface card failures.
Spectral Measurement Systems
Precision optical measurement instruments for colour density and gamut verification. Typical faults include lamp degradation, CCD array sensor failures, and optical calibration errors.
Display and HMI Terminals
Industrial touchscreen and operator interface panels for Grapho Metronic systems. Common repairs address LCD panel failures, resistive touch unresponsiveness, and communication daughterboard faults.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GRAPHO METRONIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRAPHO METRONIC equipment arriving at our workshop.
- ✓Colour sensor drift and calibration failure — Optical contamination, LED lamp aging, or internal reference standards degradation in Grapho Metronic spectrophotometric probes. Extended operation without maintenance accelerates sensor offset.
- ✓Ink pump controller not responding — Failed driver relay modules or corroded solenoid valve connectors in Grapho Metronic dosing systems, especially in humid Indian packaging plants. Power supply ripple can also degrade controller boards.
- ✓Display screen goes black or shows garbled text — Backlight inverter failure or LCD panel degradation in Grapho Metronic HMI terminals exposed to high-temperature print floors. Communication cable intermittency also causes display corruption.
- ✓Process controller loses communication with sensors — Damaged RS485 interface cards or corroded M12 sensor connectors in Grapho Metronic process controllers. EMI from adjacent press motors can corrupt serial data buses in poorly shielded installations.
- ✓Density readings fluctuate or show zero output — CCD photodiode array degradation or aperture plate misalignment in Grapho Metronic measurement heads. Calibration drift without proper reference standards also causes incorrect readings.
- ✓Firmware update failure or bootloader corruption — Power loss during firmware upload to Grapho Metronic controllers or defective flash memory cells. SD card read errors during configuration restoration cause boot sequence failures.

Frequently Asked Questions — GRAPHO METRONIC Repairs
Do you repair Grapho Metronic equipment anywhere in India?+
Yes. Synchronics repairs the full Grapho Metronic product range including colour controllers, ink dosing systems, process modules, and spectral measurement instruments. We offer PAN India door pickup from Mumbai, Delhi, Pune, Ahmedabad, Hyderabad, Chennai, Bangalore, Kolkata and all industrial cities. Repairs are completed at our factory in Vadodara, Gujarat within 7-10 working days.
What is the typical turnaround time for Grapho Metronic colour control system repair?+
Standard repairs take 5-7 working days from receipt. Sensor recalibration and module replacement are completed within this window. Urgent repairs with expedited testing are available on request. Synchronics provides daily repair status updates and arranges express courier return at customer cost if needed.
How do you ensure Grapho Metronic sensor accuracy after repair?+
Synchronics uses NIST-traceable Grapho Metronic calibration plates and verification standards. All colour sensors are calibrated to original factory specifications (typically +/- 0.5 dE accuracy). We provide calibration certificates and sensor response curves with every repair. Post-repair testing on known print samples ensures colour matching performance is restored.
Can you repair Grapho Metronic boards that have water or chemical damage?+
Yes. Synchronics is experienced in chemical cleaning and board restoration for printing plant environments. We use ultrasonic cleaning with precision solvents, replace corroded connectors, and reflow damaged solder joints. Water-damaged boards undergo drying and component replacement. However, severe damage may require board replacement depending on component availability.
Do you supply spare parts for Grapho Metronic systems?+
Synchronics maintains a stock of common Grapho Metronic spare parts including sensor modules, relay boards, display panels, and connector assemblies. We source original components through authorized distributors and also supply equivalent quality alternatives for obsolete parts. Custom harnesses and interface cables are fabricated in-house for damaged wiring.
How do I send my GRAPHO METRONIC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a GRAPHO METRONIC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on GRAPHO METRONIC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your GRAPHO METRONIC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
