According to GlobalData’s company profile on Fujifilm, AI-assisted medical imaging was a key innovation area identified from patents. Fujifilm's grant share as of June 2024 was 44%. Grant share is based on the ratio of number of grants to total number of patents.
The granted patent US12044972B2 outlines a method for manufacturing flexographic printing plates, which are essential in the printing industry for producing high-quality images. The method involves several key steps: an exposure step where a photosensitive layer in a flexographic printing plate precursor is imagewise exposed, followed by a development step using an aqueous developer. This developer contains a surfactant with a molecular weight of 1000 or more and water, which aids in forming distinct non-image and image areas on the plate. After development, a rinsing step is performed to wash the non-image and image areas with water, ensuring clarity and precision in the final product.
The claims further specify that the surfactant can be an anionic type and should be present in a concentration ranging from 0.005% to 5% by mass. Additionally, the aqueous developer may include components such as alkali metal carbonates or hydroxides to enhance its effectiveness. The patent also details specific structural formulas for the surfactant, indicating a focus on polymers with particular repeating units. This method aims to improve the efficiency and quality of flexographic printing plates, which are crucial for various printing applications.
