Operapath is high-definition 200 LPI lenticular sheet that can either switch high-quality images or express depth to an image. Conventional offset lenticular printing couldn't handle less than 1,000 batches, but market needs were growing towards multikind and small quantity production. To fulfill the market needs we added an ink-receiving layer to our lenticular sheet, enabling an inkjet printer to print directly on it. We also developed design and image processing technology to create high quality image switching print and high quality depth image for our lenticular sheet.
