Solution Overview
Problem
Existing methods for creating transferrable decorations with pre-spaced graphic elements are time-consuming, difficult to apply to complex or rough surfaces, and require manual cutting and scrap removal, making them inefficient and prone to adhesion issues on surfaces like wall plaster or wood.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cutting and scrap removal steps are used to create pre-spaced graphic elements, then the decoration can be made with separated graphic elements, but the production time increases significantly and the process becomes complex
Solution Approach 1:
The patent replaces manual mechanical cutting and scrap removal operations with a digital printing system that directly deposits adhesive material in the precise locations where graphic elements will be placed. The printing head moves across the support sheet and deposits adhesive only in the areas corresponding to future graphic element positions, eliminating the need for physical cutting and manual scrap removal entirely.
Solution Approach 2:
The patent performs the adhesive deposition action in advance, before the graphic elements are actually applied. By pre-positioning the adhesive material on the support sheet in the exact locations where graphic elements will be placed, the system prepares the substrate beforehand, so that when graphic elements are applied, they automatically adhere to the correct positions without requiring subsequent alignment or positioning operations.
2Adaptability or versatility
If traditional adhesive methods are used on rough surfaces like wall plaster or wood, then the decoration can be applied to various surfaces, but adhesion reliability decreases and elements may detach
Solution Approach 1:
The patent applies adhesive material locally only in the specific areas where graphic elements will be placed, rather than covering the entire support sheet. This localized adhesive application ensures that each graphic element receives adequate adhesive coverage precisely where needed, while avoiding excess adhesive that could interfere with adhesion on rough surfaces. The adhesive is deposited in controlled patterns that match the underlying surface topology.
Solution Approach 2:
The patent employs digital printing technology that can precisely control adhesive deposition parameters such as drop size, spacing, and distribution density. By adjusting these parameters, the system optimizes adhesive application for different surface types - using smaller, more precisely spaced adhesive drops for rough surfaces like plaster or wood, and larger drops for smoother surfaces, thereby maintaining reliable adhesion across diverse substrates.
3Manufacturing precision
If cutting plotters and manual scrap removal are used, then graphic elements can be precisely separated, but the device complexity and operational difficulty increase
Solution Approach 1:
The patent replaces complex mechanical cutting equipment (cutting plotters) with a digital printing system that uses a printing head to deposit adhesive material. Instead of physically cutting the support sheet to separate graphic elements, the system uses controlled adhesive deposition to define element boundaries and positions, eliminating the need for mechanical cutting tools, blades, and associated complex mechanisms.
Solution Approach 2:
The patent uses digital printing technology to create a copy or representation of the desired graphic element layout by depositing adhesive material in the exact patterns and positions where elements will be placed. The printing system reads digital design data and reproduces the adhesive pattern as a precise copy of the intended element arrangement, achieving accurate separation and positioning without physical contact or mechanical cutting.
4Ease of operation
If application tape is used to transfer graphic elements, then the decoration can be applied to surfaces, but the process requires additional materials and steps increasing complexity
Solution Approach 1:
The patent extracts or removes the application tape intermediary from the traditional transfer process. Instead of using application tape to pick up and transfer graphic elements from one surface to another, the system allows graphic elements to be applied directly to the target surface through controlled adhesive deposition on the support sheet, eliminating the need for application tape and the associated pick-up and transfer operations.
Solution Approach 2:
The patent merges the adhesive application function with the support sheet itself. Rather than using separate components (application tape, support sheet, then removal), the adhesive is integrated directly onto the support sheet in the precise locations needed, combining multiple functions into a single integrated system that simplifies the overall application process.

AI summary
The present invention regards a process for making, by means of digital printing, transferrable decorations with pre-spaced graphic elements. More in detail, such process comprises the following operative steps: a step for arranging a sheet-like medium (2); a step for printing a graphic element (7) on the sheet-like medium (2), in which a digital printer deposits an ink layer (9) on the sheet-like medium (2) in order to make the graphic element (7) on a corresponding print area (10); a step for making an adhesive surface (11) aligned with the border (7') of the graphic element (7), such adhesive surface (11) extended on the print area (10) above the corresponding ink layer (9) and delimited by an edge (B2) coinciding with the edge (B1) of the print area (10) itself. Also forming an object of the present invention is a transferrable decoration with pre-spaced elements, in particular obtained by means of the aforesaid process.
