1. What Is a Visual Positioning System (VPS)?

A VPS integrates a camera/CCD module to capture registration marks on the substrate, processes the image to determine positional, rotational, and scaling offsets, and feeds corrections back to the printer’s motion controller in real time.

2.Advantages

Reduced Setup Time — Automatic mark detection replaces manual jigging and test prints, accelerating job changeovers.

Improved Yield — Minimizes waste from misaligned prints, saving ink and substrates.

Versatility on Irregular Surfaces — Enables precise printing on curved or shaped objects like phone cases and bottles.

3.Disadvantages

Higher Equipment Cost — Adds cameras, lighting, and proprietary software, increasing printer price by 10–25%.

Additional Maintenance — Cameras and optics must remain clean; calibration and firmware updates are required regularly.

Limited Mark Visibility — Darkt substrates may hinder mark detection, requiring special contrast inks or preprinted marks.

4. Selection Guide

Detection Speed & Accuracy — Check minimum detectable mark size (e.g., 1 × 1 mm), detection rate (>99%), and realtime correction capability.

Optics & Lighting — HighCRI LED illumination and antiglare lenses compatible with flat and curved surfaces.

Software Flexibility — Customizable fiducial mark design, support for scalin and perspective distortion correction.

Material Compatibility — Ensure support for your substrates: clear acrylic, dark plastics, textured boards, etc.

RIP Integration — Seamless integration with RIPs like Photoprint or Maintop, with builtin autocalibration features.

Optional AddOns — Rotary attachments for cylindrical printing, autofeed modules for cards/labels, and multicamera arrays for large beds.

5. MYJET Models with VPS

MYJET6090C VPS: 60 × 90 cm flatbed with singlecamera positioning—ideal for smallrun, multilayer precision jobs.

MYJETCCD085 VPS: 2.5 × 1.3 m industrial flatbed with dualcamera array—highspeed, largeformat production.

6. Conclusion

A VPS elevates UV printing from “good” to “perfect” in multilayer, variable, and irregularshape applications. When selecting a VPSequipped printer, balance accuracy requirements, material types, and budget for optimal results.
