Description
SMART-31D Dual Side ID Card Printer
The ID Card Printer SMART-31D (Dual Side Printer) is a professional automatic duplex card printer designed for businesses, schools, universities, hospitals, membership organisations and security departments that need to print information on both sides of PVC ID cards.
Manufactured by IDP, the SMART-31D uses dye-sublimation printing, automatic card feeding and an integrated card-flipping mechanism to print the front and back of a card without requiring the operator to turn it manually. The printer supports standard ISO CR80 cards, including PVC, PET and composite PVC media.
Its current published specification includes 300 dpi full-colour printing, higher-resolution 600/1200 dpi monochrome modes, edge-to-edge output, an 80-card input hopper, 25-card output hopper, USB connectivity and optional Ethernet.
For full-colour front printing with black printing on the reverse using a YMCKOK ribbon, the SMART-31D is rated at approximately 29 seconds per card, or up to 124 cards per hour.
What Is the SMART-31D?
The SMART-31D is the dual-sided model in IDP’s SMART-31 card-printer family.
It is designed to create cards such as:
- Employee ID cards
- Student ID cards
- University cards
- Membership cards
- Healthcare ID cards
- Visitor cards
- Access-control cards
- Loyalty cards
- Transport passes
- Event identification cards
IDP’s current product catalogue continues to list the SMART-31D as part of its card-printer portfolio for small and mid-sized organisations.
The major difference between the SMART-31D and a basic single-sided printer is its built-in duplex mechanism: after printing one side, the printer automatically flips the card and processes the reverse side.

Why Should You Buy the SMART-31D?
The SMART-31D is most useful when an organisation regularly needs professionally printed ID cards with different information on the front and back.
A typical employee card, for example, might use:
Front side
- Employee photograph
- Name
- Employee number
- Department
- Company logo
Back side
- Barcode
- QR code
- Emergency information
- Return instructions
- Terms of use
- Access information
Because the SMART-31D flips the card automatically, the operator does not need to manually feed each card twice.
Key advantages include:
- Automatic dual-sided printing
- Full-colour ID production
- 300 dpi photo and text output
- Edge-to-edge printing
- CR80 PVC-card compatibility
- Automatic card feeding
- 80-card input capacity
- USB connectivity
- Optional network connectivity
- Optional card-encoding modules
- Colour and monochrome ribbon choices
- Compact desktop operation
How Does Automatic Dual-Sided Printing Work?
The SMART-31D contains an integrated card-flipping mechanism.
A simplified workflow is:
- A blank card enters from the input hopper.
- The printer processes the first side.
- The flipper mechanism receives the card.
- The card is automatically turned over.
- The second side is printed.
- The finished card is moved to the output hopper.
The user does not have to remove the card halfway through the job.
This is especially useful when printing batches of:
- Employee IDs
- Student cards
- Membership cards
- Access cards
- Visitor credentials
The SMART-31 user manual specifically provides driver controls for selecting one-side or both-side printing when a duplex mechanism is installed.
How Fast Does the SMART-31D Print?
Current SMART-31D specifications publish different speeds depending on the ribbon and printing method.
| Printing mode | Published speed |
|---|---|
| Monochrome | Approx. 5 sec/card |
| Monochrome throughput | Up to 720 cards/hour |
| YMCKO | Max. approx. 23 sec/card |
| YMCKO throughput | Up to 156 cards/hour |
| YMCKOK duplex | Approx. 29 sec/card |
| YMCKOK throughput | Up to 124 cards/hour |
For a true dual-sided colour/black ID workflow, 124 cards per hour using YMCKOK is the more relevant throughput figure.
Actual production may be slower because of:
- Image processing
- Database loading
- Card encoding
- Application workflow
- High-resolution monochrome printing
- Network communication
- Card cleaning
- Operator intervention
Is the SMART-31D Really a 1200 dpi Printer?
Yes, but this requires an important qualification.
IDP lists:
- 300 dpi for colour
- 600 dpi monochrome
- 1200 dpi monochrome
The higher-resolution modes do not mean that full-colour photographs are printed at 1200 dpi.
For accurate product marketing, GS Systemz should use:
300 dpi full-colour printing with up to 1200 dpi monochrome capability.
This is more precise than simply advertising “1200 dpi printing.”
Does the SMART-31D Print Edge to Edge?
Yes. IDP specifies edge-to-edge printing for the SMART-31 series.
This helps create professional cards where artwork can extend close to the card boundaries.
Edge-to-edge printing is useful for:
- Corporate branding
- University identity cards
- Membership designs
- Full-card backgrounds
- Security graphics
- Colour-coded departments
Minor unprinted borders can still occur because of card tolerances, mechanical alignment and artwork positioning.
Which Cards Does the SMART-31D Support?
The SMART-31D is designed for standard ISO CR80 cards.
CR80 is the familiar bank-card-sized format used for most:
- Employee badges
- Student IDs
- Membership cards
- Access-control cards
- Loyalty cards
Supported card materials include:
- PVC
- PET
- Composite PVC
Published thickness support ranges from approximately:
0.38mm / 15 mil to 0.76mm / 30 mil.
Before purchasing speciality cards, confirm compatibility for:
- Adhesive-backed cards
- Smart cards
- Contactless cards
- Magnetic-stripe cards
- Pre-punched cards
- Unusual surface coatings
What Size Is a CR80 ID Card?
Standard CR80 cards measure approximately:
54 × 86mm, or roughly 2.12 × 3.38 inches.
The Pakistan SMART-31D distributor specifies this standard directly.
This is approximately the same footprint as a standard credit or debit card.
How Many Cards Does the SMART-31D Hold?
The printer’s automatic feeding system provides:
- 80-card input hopper
- 25-card output hopper
This allows moderate batches to be printed without inserting every card manually.
For example, an HR department could load employee records into its card application, place blank cards into the hopper and allow the printer to process a batch automatically.
Which Ribbon Does the SMART-31D Use for Dual-Sided Cards?
For the most common dual-sided workflow, the important ribbon is YMCKOK.
YMCKOK represents:
- Y — Yellow
- M — Magenta
- C — Cyan
- K — Resin black
- O — Clear overlay
- K — Additional resin black for the reverse side
IDP lists ribbon 659376 YMCKOK, rated for approximately 200 cards per roll.
This ribbon is useful where:
- Front = full colour
- Back = black text/barcode
That combination is common for employee, student and membership ID cards.
Which SMART-31 Ribbons Are Available?
Common SMART-31 consumables include:
| Ribbon | Typical purpose | Published yield |
|---|---|---|
| YMCKOK 659376 | Colour front + black reverse | Approx. 200 cards |
| YMCKO 659366 | Full colour + black + overlay | Approx. 250 prints |
| YMCKO 659863 | Alternate YMCKO roll | Approx. 100 prints |
| K Resin Black | Monochrome black | Approx. 1200 prints |
Additional speciality ribbons may be available for:
- UV printing
- White printing
- Blue
- Red
- Metallic colours
- Scratch-off applications
Always check ribbon compatibility with the exact SMART-31 printer and intended card design.
What Does the Overlay Panel Do?
The O in YMCKO and YMCKOK is a clear overlay panel.
It is applied over the printed colour area to provide some added surface protection.
The overlay can help protect against normal handling, but it is not equivalent to full card lamination.
For cards exposed to heavy wear, harsh environments or multi-year use, a dedicated laminating card-printer system may be more suitable.
Can the SMART-31D Print UV Security Features?
The SMART-31 platform supports speciality ribbon options that can be used for UV-related security printing. Current SMART-31D product material specifically highlights low-cost security using UV printing.
UV printing can help add a security element that is less obvious under normal viewing conditions.
Possible applications include:
- Employee badges
- University IDs
- Membership cards
- Access cards
It should not be marketed as making a card counterfeit-proof.
Can the SMART-31D Encode Magnetic Stripe Cards?
Yes, with the appropriate optional encoder.
Published magnetic encoding support includes:
- ISO 7811
- Track I
- Track II
- Track III
- HiCo
- LoCo
- JIS II
A standard printer without the magnetic encoder cannot gain magnetic encoding merely through software.
Confirm the exact printer part number before promising this capability.
Can the SMART-31D Encode Contact Smart Cards?
Yes, when fitted with the appropriate optional contact encoder.
Current specifications include ISO 7816 smart-card support.
This can be relevant for specialised:
- Employee credentials
- Membership cards
- Authentication systems
- Access-control applications
Software integration must also support the card technology.
Can the SMART-31D Encode Contactless Cards?
Optional contactless encoding configurations are available.
Published technologies include combinations of:
- ISO 14443 Type A/B
- MIFARE
- DESFire
- iCLASS
- NFC-related standards
- FeliCa on current configurations
Encoding capabilities are hardware options, not standard features on every SMART-31D.
When selling an encoding version, GS Systemz should publish the complete part number and installed encoder.
Does the SMART-31D Support USB?
Yes.
USB is the standard communication method in the current SMART-31D specification.
USB is appropriate when:
- One computer controls the printer.
- The printer sits close to the workstation.
- Network access is unnecessary.
- Simple deployment is preferred.
Does the SMART-31D Have Ethernet?
Ethernet is listed as an optional upgrade, not a standard interface on every SMART-31D.
Ethernet is useful when:
- The printer needs to be placed away from the main PC.
- IT staff want network access.
- Several authorised users need controlled access.
- A permanent TCP/IP printer connection is preferred.
Before advertising Ethernet, verify the rear ports and complete printer SKU.
Does the SMART-31D Have Wi-Fi?
Wi-Fi should be treated as an optional/configuration-dependent capability rather than a standard SMART-31D interface.
Current standard specifications identify USB and optional Ethernet. Separate SMART Wi-Fi hardware has also existed for the SMART-31 platform.
GS Systemz should confirm that the exact unit contains the required wireless module before publishing Wi-Fi as included.
Does the SMART-31D Work With Windows 11?
The current SMART-31D product specification lists:
- Microsoft Windows 10/11
- macOS
- Linux
as supported platforms.
For Windows deployment:
- Install the current IDP printer driver.
- Connect through USB or configured Ethernet.
- Add the SMART-31 printer.
- Set the CR80 card format.
- Select single- or double-sided printing.
- Configure ribbon and colour settings.
- Print a test card.
Older documentation may list Windows 7/8/10 because it was created before Windows 11. Current driver compatibility should take priority over older reseller listings.
Does the SMART-31D Work With macOS or Linux?
Current product specifications list both macOS and Linux support.
However, card-design software is a separate consideration.
The printer driver may support an operating system while a particular card-design application does not.
Before deployment, verify:
- Operating-system version
- Printer driver
- ID-card design software
- Database connectivity
- Camera integration
- Encoding software
- Network configuration
Is ID Card Design Software Included?
Software inclusion depends on the package sold.
Some international SMART-31D bundles include card-design software, cards and ribbons, while printer-only packages may not.
GS Systemz should clearly specify whether its package contains:
- Printer only
- Printer driver
- ID design software
- Camera
- PVC cards
- Ribbon
- Cleaning kit
Do not copy another retailer’s bundle contents onto a printer-only SKU.
