Abstract:
1. A method for tactile printing on a first output medium, the method comprising: moving, with a motor in a printer, the first output medium at a first speed; depositing, with an ink print head in the printer, a visible ink on the first output medium; providing a clear liquid adhesive in an uncured form, the clear liquid adhesive including clear fluorescent pigments; adjusting the first speed of the motor to a second speed, the second speed being lower than the first speed and being sufficient for moving the first output medium to complete deposition and cure the clear liquid adhesive on the first output medium; depositing the clear liquid adhesive as droplets of about 0.25-0.75mm high on top of at least a portion of the visible ink to a predefined area on the first output medium, the clear liquid adhesive capable of retaining a tactile shape; curing, with a curing source in the printer, the clear liquid adhesive to form tactile regions on the first output medium; scanning, with a black light scanner, the first output medium to detect fluorescent pigments in the clear liquid adhesive; identifying input information from the fluorescent pigments for creating tactile regions; and depositing the clear liquid adhesive on a second output medium to create a copy of the input information on the second output medium.
