Marker-Guided EIR Registration for Laminated Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of matching digitally printed images with embossed in register (EIR) layers on substrates is hindered by material contraction, leading to curling and reduced image clarity, and alignment errors are common.
Innovation Solution
A laminated article is designed with a printed image having identifiers that align with an EIR layer, using optical or non-optical capturable markers to ensure precise matching of patterns along the longitudinal and transverse axes, and employing UV-curable inks and adhesives for bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If liquid material is deposited onto the substrate to form an EIR layer, then texture and aesthetic appearance are improved, but material contraction causes the board to curl and reduces image clarity
Solution Approach 1:
The patent applies identifiers to the printed image before the EIR layer is applied. This preliminary marking allows the alignment system to detect and compensate for material contraction and curling that occurs during the deposition and curing processes, enabling precise registration between the printed image and embossed pattern without requiring excessive liquid material
Solution Approach 2:
The patent replaces manual or mechanical alignment methods with an optical detection system that reads identifiers (such as barcodes, QR codes, or optical markers) on the printed image. This optical system automatically determines the position of the EIR layer relative to the printed image and adjusts the embossing process accordingly, eliminating the need for mechanical registration marks and reducing the liquid material required for EIR layer formation
2Ease of manufacture
If traditional alignment methods are used to match the EIR layer with the digitally printed image, then the process is simple, but alignment is difficult and prone to error
Solution Approach 1:
The patent replaces mechanical or visual alignment methods with an automated optical detection system. Identifiers such as barcodes, QR codes, or optical markers are printed on the printed image and detected by optical sensors during the embossing process. This optical system automatically calculates the position of the EIR layer relative to the printed image and adjusts the embossing parameters to achieve precise alignment, eliminating human error and improving consistency
Solution Approach 2:
The patent implements a feedback mechanism where the optical detection system continuously monitors the position of identifiers on the printed image during the embossing process. The system uses this feedback information to dynamically adjust the embossing head position and EIR layer application parameters in real-time, ensuring accurate alignment between the printed image and embossed pattern even when material contraction or substrate deformation occurs
