We are developing an automated solution for lenticular image processing and printing, aimed at streamlining the traditionally labor-intensive process of aligning lenticular lenses and generating print-ready interlaced images. The project involves using a UV flatbed printer, an overhead camera system, and a Python-based web application to automate the alignment, pitch test, and printing process. The goal is to reduce human error, improve efficiency, and provide print shops with a tool that can handle variable LPI (Lines Per Inch) lenses and create precise lenticular prints.
Job Description:
We are looking for an experienced developer to design, implement, and optimize an automated lenticular printing solution. The ideal candidate will have experience in image processing, camera integration, and backend development, with a strong understanding of the printing industry’s needs. You will be responsible for developing a Python backend that communicates with the camera system and UV flatbed printer, automating key tasks such as LPI calculation, lens alignment, and interlacing image frames. Additionally, you will assist in developing a user-friendly web interface for print shop operators to generate and send print jobs to the printer with minimal manual intervention.
Key Responsibilities:
1. LPI Calculation & Pitch Test Automation:
- Develop algorithms to calculate the pitch test LPI (Lines Per Inch) based on the lens dimensions and intended viewer distance.
- Implement a method to measure LPI with high precision, up to the nearest 1/1000th inch, using an overhead camera system.
- Handle multiple LPI variants ranging from 10-100 LPI.
2. Camera Integration & Image Capture:
- Integrate a high-resolution overhead camera to capture the lenticular lens’ orientation and position relative to the printer bed.
Develop software to detect the lens alignment and skew, using registration marks printed on the printer bed for precise calibration.
Ensure the system accurately calculates lens orientation and prepares the print job based on the captured image.
3. Image Interlacing & Frame Alignment:
- Create algorithms to interlace image frames into a single print-ready file that will be applied to the lenticular lens.
- Prevent frame resets in the center of the final lenticular print to ensure smooth transitions.
4. Web Interface & API Development:
- Develop a web-based application with a Python backend that allows print shop operators to upload lenticular images, input lens dimensions, and receive downloadable interlaced images.
- Build an API, webhook, or similar system to communicate between the web app, the camera system, and the printer.
- Automate the process from image generation to job queue submission, allowing operators to initiate printing with a single button press.
5. Testing & Optimization:
- Conduct trial-and-error testing to refine the system and improve measurement accuracy.
- Address challenges related to tolerance and precision in LPI calculations and lens alignment.
6. Collaboration & Documentation:
- Collaborate with the hardware team to ensure seamless integration of the camera and printer systems.
- Document the system architecture, workflows, and codebase for future maintenance and scalability.
Required Skills & Qualifications:
- Strong experience with Python and backend web development.
- Experience with image processing and working with high-resolution cameras for precision measurement.
- Familiarity with printer integration and developing software that communicates with industrial machines (e.g., UV flatbed printers).
- Knowledge of API development and webhooks for system communication.
- Understanding of the printing process, especially for lenticular printing and image interlacing.
- Ability to troubleshoot and optimize precision-critical systems.
- Strong problem-solving skills and ability to work in a trial-and-error environment to refine the solution.
Preferred Qualifications:
- Experience with openCV
- Experience with lenticular printing or related imaging technologies.
- Familiarity with camera calibration and computer vision techniques for accurate lens alignment and measurement.
- Experience with frontend web technologies (HTML, CSS, JavaScript) to assist with the user interface development.
Work Environment:
- This will be a remote position with flexibility in working hours, but regular collaboration is expected.
- We will need a developer who is comfortable with trial and error and can adapt to evolving technical challenges.
