DiPaMat LI Wh04 : benefits
Different print technology, same quality (legibility, adhesion, pencil hardness, ….)
Agfa Materials: for the PCB Industry
BUT

Cheaper
• Less production steps
• No phototool needed

Short cycle time
• From CAD / CAM directly to printer
• No screen needed

Can print variable data
• Design changes & variable data per panel, per board
• Better positioning and panel distortion compensation

Ecology
• No screen cleaning

DiPaMat LI WH04: adhesion
Agfa Materials: for the PCB Industry

Print on solder mask:
• Adhesion is excellent to good depending on:
- Brand and type of solder mask
- Semi - or fully cured
- UV bump (after printing)
- Thermal baking process

Print on copper:
• Limited. Do the test to find out whether it fits your needs.

Print on substrate (FR4, polyimide, …..)
• Limited. Do the test to find out whether it fits your needs.

DiPaMat LI WH04: scratch resistance
Agfa Materials: for the PCB Industry

Print on solder mask:
• Scratch resistance depending on:
- Brand and type of solder mask
- Semi - or fully cured
- UV bump (after printing)
- Thermal baking process

Print on copper:
• Limited. Do the test to find out whether it fits your needs.

Print on substrate (FR4, polyimide, …..)

DiPaMat LI WH04: sedimentation &
recovery
Agfa Materials: for the PCB Industry
Sedimentation results in clogging the printing head
Confirmed by printer manufactures:
- Wh04 shows no sedimentation,
even after several days
-Wh04 needs very little purging
before a start up after the weekend

DiPaMat LI Cleaning solution
Agfa Materials: for the PCB Industry

Legend ink cleaning solution is used:
• To clean a system at start up
• To clean a system when switching ink type
• To clean a system prior to a long stand still

Remark: Legend ink cleaning solution
•
•
•

all printer heads can be cleaned using this one product
all Agfa legend inks can be cleaned using this one product
only Agfa legend inks can be cleaned using this product
When converting from a different ink type to Agfa:
• Flush the printer with the designated cleaning solution of the used
ink
• Clean with Agfa legend ink cleaning solution
• And vice versa.
