A DOVID applicator uses controlled heat, pressure, feed and registration to position a diffractive optical security feature on a document or substrate. Dimuken offers configurations for sheet-fed, continuous-web and polycarbonate workflows.
Where these systems fit
Dimuken’s official range addresses registered hologram, OVD and Kinegram application for security printing and document-finishing operations.
- Passports, visas and identity documents
- Certificates, cheques and other secure documents
- Tickets, vouchers and scratch cards
- Security and product-authentication labels
- Polycarbonate sheets used in plastic card production
Feed format and registration are central decisions
Machine selection depends on whether material is sheet-fed, pin-fed, pinless web-fed or supplied as polycarbonate rolls or sheets. Registered optical images require controlled positioning; random-pattern and conventional hot-foil work create different requirements.
- DC-1603
- Configurable for sheet-fed or continuous-web registered application
- DC-1605
- Developed for synthetic laminates such as polycarbonate
- PC Line
- Integrated polycarbonate unwind, application and sheeting workflow
- Variable data
- Separate DC-9740 inkjet equipment within Dimuken’s official range
What to provide for line evaluation
Send the document or substrate dimensions, material, feed format, foil/security feature information, required positions, throughput target, upstream/downstream process and sample material. Final specifications must be confirmed against the selected model’s current Dimuken documentation.
Technical application example · Polycarbonate documents
Registered DOVID application on polycarbonate security documents
For ID, passport and other high-security documents, the optical device must not only be present; it must be positioned repeatably without compromising the polycarbonate structure or downstream lamination process.
The evaluated configuration combines controlled polycarbonate handling with precision hot-stamping of registered DOVID or holographic images. Final configuration depends on material thickness, image layout, required registration tolerance and downstream lamination.
- Surface / substrate
- Polycarbonate sheet or laminate and material thickness
- Process
- Controlled feed and registered hot-stamping
- Critical validation
- Image layout, registration and downstream lamination
Technical application example · Security printing
Registered hologram application for sheet-fed or continuous-web production
The engineering challenge in security finishing is not simply applying a hologram but transferring each registered foil image repeatedly to the intended position. The configuration therefore depends on sheet/web handling, registration logic and the number of foil streams required.
Evaluation should cover substrate, feed mode, image repeat, print-mark logic, foil direction and stamping parameters as one integrated process.
- Surface / substrate
- Security document, label stock or defined web material
- Process
- Sheet-fed, pin-fed or pinless continuous-web handling
- Critical validation
- Image repeat, print mark, foil direction and registration
Frequently asked questions
What does DOVID mean?
DOVID stands for diffractive optically variable image device: an optical security feature whose appearance changes with viewing angle or illumination.
Can one machine handle sheets and continuous web?
The Dimuken DC-1603 can be configured for sheet-fed and continuous-feed operating modes. The correct configuration depends on the substrate and registration workflow.
Is there a system for polycarbonate?
Dimuken publishes the DC-1605 for synthetic laminates and a dedicated PC Line for applying registered DOVIDs or holograms in polycarbonate workflows.
