Embodiments of the invention are directed to a system, method, or computer program product for individual application flow isotope tagging within a network infrastructure. In this regard, the invention is configured to construct a robotic process automation application structured to determine data flow associated with a first technology application within a myriad of data transmission flows between a plurality of network nodes of the network infrastructure. The invention configures a robotic process automation application for inserting a unique isotope tag string in data packets associated with first technology activity performed by the first technology application, prior to transmission from a source network node. The invention is configured to track, in real time, the current locations of the data packets among the multitude of data packets being transmitted in the network, based on the first unique isotope tag string.

A single plasma nozzle of a plasma treatment station is used to treat the card surface prior to performing drop-on-demand printing on the card surface. The single plasma nozzle has a plasma discharge width that is less than the width of the card. The card and the plasma nozzle are moved relative to one another using a two direction control scheme during plasma treatment in order to be able to plasma treat a desired area of the card surface. The card and the plasma nozzle may also be moveable toward or away from one another to change the distance therebetween.

Methods and systems are disclosed for printing vibrant grey color(s) on plastic cards. The following features, which can be used individually or in any combination thereof, can be implemented to achieve the vibrant grey color(s): 1) use of CMYK pigment inks to achieve CMYK printing; 2) a pixel extraction process and/or a print trapping process; 3) two separate print commands including a CMY (or CMYK)+blending print command and a K+blending print command; and 4) proper card set-up.

Disclosed herein is a method for encoding an illustration on a target surface, where the illustration may be visible when light is shone on the surface from a light source with a predetermined position. The method may include converting the illustration into a grayscale illustration, specifying the position of the light source; generating a three dimensional surface having a grid of smaller surfaces thereon, where each smaller surface may represent a corresponding pixel of the grayscale illustration. Each smaller surface may be oriented with respect to the light source such that reflected light from each smaller surface has a reflection intensity equal to the light intensity of the corresponding pixel of the greyscale illustration; and making the target surface out of a material using the generated three dimensional surface as a template.
