This disclosure describes substrate(s) formed with a three-dimensional (3D) feature thereon, and method(s) of printing the same. One method includes identifying a plurality of locations on a substrate surface where the three-dimensional feature will be formed, determining a height value of the three-dimensional feature at each location, assigning a grayscale value to each location based on the height value, and applying ink to the substrate surface at each location according to the assigned grayscale value.

There is provided a method of manufacturing a glass container that can manufacture a glass container, which includes a bubble formed in a bottom portion and independent of the outside, with high yield by accurately controlling the position and size of the bubble. A method of manufacturing a glass container that includes a mouth portion, a body portion, and a bottom portion, includes: a step of molding a glass container, in which a bubble is not yet formed, from molten glass; a step of forming a bubble-forming passage by pulling out a needle-like member after inserting the needle-like member into a bottom portion of the glass container in which a bubble is not yet formed; a step of injecting air from an inlet of the bubble-forming passage to form a reverse teardrop-shaped internal space, which is widened in the bottom portion from the bubble-forming passage as a starting point, in the bottom portion of the glass container in which a bubble is not yet formed, and to obtain a glass container that includes an internal space communicating with the outside; and a step of closing an inlet side of the reverse teardrop-shaped internal space by flow of not yet cured glass, which is caused by the potential heat of the not yet cured glass, to obtain a glass container that includes a bubble formed in the bottom portion and independent of the outside.

A process for forming coating on an interior surface of a glass container. A glass preform is formed at blank molding station from a gob of molten glass. Thereafter, a glass container is formed at a blow molding station from the glass preform. A coating material comprising a suspension of nanoparticles in a liquid medium is introduced into an interior of the glass preform or the glass container while the glass is still hot from being formed. Heat from the glass is transferred to the liquid medium to vaporize the liquid medium and form a coating on an interior surface of the glass preform or the glass container. Thereafter, the glass container is annealed.

An improved system and method for forming falling hot glass gobs which will be molded into glass containers in an Individual Section (IS) machine is disclosed which controls the weight, length, and shape of such glass gobs as they are produced. The system includes a gob feeder apparatus and a gob shearing mechanism a controller using models being used to correlate the effect of a number of feeder control settings on gob weight, length, and, shape. The controller is configured to adjust various feeder control settings based on a prioritized order of the feeder control settings such that gobs having different physical characteristics for different ones of the individual sections can be produced during a single machine cycle. By implementing the models, a closed loop system has been developed to set up controls to achieve the desired gob forming for each individual section and cavity.
