Factory Routine Record: Shop Floor Quality Inspection & Dispatch Logistics
An inside look at daily operational routines, manual inspection procedures, and secure shipment procedures at Chuangda (Shenzhen) Printing Equipment Group.
Maintaining consistent print production performance requires strict quality assurance at every phase of offset plate manufacturing. At Chuangda (Shenzhen) Printing Equipment Group, routine factory procedures combine standardized manual inspection with disciplined material handling protocols to safeguard prepress consumables prior to dispatch.
Manual Surface Quality Inspection Routine
During daily manufacturing checks, trained operators conduct manual visual inspections under controlled overhead lighting. Each large-format blue CTP sheet is carefully lifted from palletized storage stacks to verify surface integrity.
- Handling Protocol: Operators wear clean protective gloves to prevent fingerprints, grease marks, or surface contamination on sensitive emulsion layers.
- Surface Illumination Check: Plates are angled under bright overhead lighting to detect micro-scratches, pinholes, or uneven photo-coating application.
- Lay-Flat Placement: After visual inspection, plates are flipped smoothly and laid flat onto padded inspection tables to prevent edge bending or physical distortion.

Plate Structure Verification & Edge Identification Marking

Physical verification confirms the structural distinction between the front photosensitive blue emulsion layer and the silver anodized aluminum base plate. Every finished plate includes standardized batch coding along the rear margin.
- Front Coating Layer: Smooth blue emulsion designed for precise laser imaging response and consistent dot reproduction.
- Base Substrate: Rigid silver aluminum alloy sheet providing mechanical stability during high-speed offset press cylinder rotation.
- Batch Traceability Stamping: Clear text jet-printed on the silver backing edge indicates the specific model designation CTP-S alongside production date tracking details.
Warehouse Dispatch & Logistics Handling Operations
Final stage operations involve transferring packed wooden crates and heavy plate pallets from the warehouse facility onto transport cargo trucks.
- Equipment Loading: Forklift operators utilize heavy-duty forklifts, such as unit ID 4-GK000834, to handle palletized plate packages smoothly.
- Precision Alignment: Forklift forks elevate heavy wooden pallets to align precisely with the flatbed cargo truck bed height.
- Coordinated Placement: Ground logistics teams coordinate with deck personnel to guide the pallet placement, preventing sudden shifts or packaging damage during transit.
