Embodiment 1

[0041] Edible, invisible inks can be prepared by performing the following steps. First, a 0.05 molar sulfuric acid aqueous solution was prepared. After transferring this solution to a tube, 18.8 mg of quinine sulfate was added to the acid solution. Finally, 2 ml of ethanol was added to the solution, and the solution was mixed until the quinine sulfate was well dispersed.

Embodiment 2

[0043] Edible, invisible inks can be prepared by first preparing the ink vehicle by combining 8 ml of water, 1.7 ml of ethanol, and 0.3 ml of glycerin. Then, 90 mg of riboflavin phosphate was added to the ink vehicle and mixed until the riboflavin phosphate was well dispersed.

[0044] Typical Implementation and Operation

[0045] Once formed, the edible, invisible ink (260; figure 2 ) can be sprayed on the pharmaceutical product (270; figure 2 ) or other substrate to form the desired image that is invisible to the naked eye under normal white light conditions, but visibly fluoresces and reveals the image when exposed to UV light. Figure 4 Implementation of the present printing system (200; figure 2 ) to use edible, invisible ink (260; figure 2 ) method of labeling a pharmaceutical product. Such as Figure 4 As shown in , the method begins by placing a pharmaceutical product under the ink dispensing system (step 400). Once in place, the ink dispensing system selectivel...

Abstract

An ink, wherein the ink (260) includes a jettable vehicle, and a colorant configured to fluoresce in a visible light range when exposed to an ultraviolet (UV) light (515), wherein the ink (260) is edible, and wherein the ink (260) is invisible when viewed under white light conditions.

Description

Background technique [0001] Pharmaceutical products such as pills and capsules traditionally include some labeling. Marking or printed information on pharmaceutical products typically includes information such as logos, names or barcodes that can be used to identify the type, dose and / or source of the drug. These markings also aid in the dispensing and administration of medicines to patients. [0002] In order to label or otherwise label pharmaceutical products such as pills and capsules, methodologies must be approved by the Food and Drug Administration (FDA). FDA maintains lists of approved colorants and labels that may be used to mark or otherwise label pharmaceutical products. [0003] Traditional methods of marking pharmaceutical products such as pills and capsules include coloring the drug product with FDA-approved colorants, changing the surface appearance of the drug product by engraving, using labels on the surface of the drug product, or coloring the drug product. ...
