Single Press Plate for Authentic Wood-Look Laminates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of producing press plates and the complexity of image processing techniques make it difficult to create laminates that mimic natural materials like wood or stone using a single press plate, resulting in a lack of authenticity in the finished product.
Innovation Solution
A method involving scanning a template to generate image and relief data sets, which are used to produce multiple decorative papers that match the press plate's surface structure, allowing for the creation of various laminates with a lifelike appearance using a single press plate. This involves scanning a template, processing and scanning multiple layers, and generating image data sets that accurately represent different processing methods, such as sanding or oiling, to produce resin-impregnated decorative papers that are then pressed with a base plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a press plate is produced to match a specific decorative paper, then the laminate appearance becomes natural and authentic, but the cost increases due to the need for multiple press plates for different decors
Solution Approach 1:
The invention creates a master press plate with a relief structure that copies the essential surface features (knots, pores, grain patterns) of natural wood. This master copy can then be used to produce multiple decorative papers through printing, and the same press plate can press all these different decors, achieving both authenticity and versatility
Solution Approach 2:
The press plate is designed with a universal relief structure that captures the fundamental wood anatomy features rather than being specific to one wood species. This allows a single press plate to work with multiple decorative papers depicting different wood types, making the press plate multi-functional and reducing the need for multiple specialized plates
2Adaptability or versatility
If image processing techniques are used to adapt decorations to a pressed structure, then a single press plate can be used for various decors, but the complexity of the process increases and the natural appearance is compromised
Solution Approach 1:
The relief structure of the press plate is pre-designed to include all necessary wood anatomical features (knots, pores, grain patterns) before the decorative paper production. This preliminary preparation of the press plate eliminates the need for complex post-processing image adaptation, as the structural matching is already built into the press plate itself
3Adaptability or versatility
If image processing is used to process wood decors, then a single press plate can be used, but the lifelike appearance deteriorates because distribution and expression of knots and pores differ greatly between wood types
Solution Approach 1:
The press plate relief structure incorporates locally varied features that represent different wood anatomical characteristics (knots in some areas, pores in others, grain patterns in between). This local differentiation in the relief structure allows the single press plate to accurately reproduce the specific features of different wood types when pressing different decorative papers, maintaining lifelike appearance across various decors

AI summary
A method for producing various laminates (Lo to Ln) with a press plate (P), wherein each laminate comprises a base plate (G) and a decorative paper (Dn), characterized by the following process steps: - scanning a template (V) to generate a first image data set (B0) and a relief data set (R); - removing n layers (S1 to Sn) from the template (V); - processing each layer (S1 to Sn) with different processing methods and scanning each differently processed layer to generate n image data sets (B1 to Bn); - producing various decorative papers (Do to Dn) from the first image data set (B0) and the n image data sets (B1 to Bn); - producing the press plate (P) from the relief data set (R); - producing various laminates (Lo to Ln) from the various decorative papers (Do to Dn) by pressing the respective decorative paper with a base plate (G) using the press plate (P).
