DJ771 Epoxy Doming for Mixed-Layout Paper Stickers

The DJ771 applies epoxy resin to multiple small stickers with different shapes and sizes on a mixed-layout printed paper sheet. This demonstration uses one needle and a program execution time of 23 seconds.

Mixed designs can also support multiple needles when the same complete sheet layout is repeated at precise relative positions. The placement of corresponding stickers must match the needle arrangement.

The sheet dimensions describe the whole printed sheet. Program execution and resin curing are separate stages; include handling, curing and inspection when planning production.

Watch the dispensing needle move between the different sticker outlines on the printed sheet. The demonstration combines small labels with varied shapes in one saved layout.

Resin and curing: epoxy resin, with full cure in 15–24 hours at approximately 25°C room temperature.

A sheet can contain different sticker shapes and still be suitable for a multi-needle setup. Repeat the complete sheet layout so that each needle works on the corresponding design on its assigned sheet.

1. Repeat the same sheet layout. Corresponding stickers must have matching shapes, sizes, orientations and dispensing requirements.
2. Maintain precise relative placement. The spacing and alignment between sheets must match the physical needle positions.
3. Keep the sheets flat and stable. Reproduce their placement each time the program is run.
4. Check every needle position on actual samples. Verify the dispensing path, resin amount and edge coverage across the full arrangement.

This option suits recurring batches with repeatable sheet placement. The video above demonstrates the single-needle configuration.

DJ771 is a suitable option when the sticker-sheet layout and placement can be reproduced for a saved dispensing program. Mixed shapes alone do not require camera positioning.

If sheets or individual pieces are placed at varying positions or angles, compare the SJ4060 vision-guided setup. Choose the positioning method around your loading process, layout repeatability and sample results.

• Send the complete layout: an actual printed sheet or a dimensioned drawing showing every sticker outline and its position.
• Describe the surface: paper type, printing and any additional finish or coating.
• Show the intended arrangement: sheet spacing, orientation and loading method, especially for multiple needles.
• Specify the required finish: epoxy resin details, desired dome appearance and acceptance criteria.
• Share your production target: batch quantity and available curing space.

Test the actual printed paper with the selected resin to check edge coverage, surface appearance and adhesion after full curing.

Does 12 × 14 cm refer to each small sticker?

It is the size of the whole printed sheet. The small stickers within that sheet have different shapes and sizes.

Does the 23-second execution time include curing?

No. It describes program execution. The epoxy resin used for these samples reaches full cure in 15–24 hours at approximately 25°C.

Can different sheet layouts share one multi-needle program?

A shared multi-needle movement requires matching sticker positions and dispensing requirements at the corresponding needle offsets. Repeat the same complete layout within a needle group, or evaluate a separate program or single-needle setup for a different layout.
