Abstract: Certain examples described herein relate to color calibration. In certain cases, a plurality of test patches are printed with a printing system, the test patches corresponding to a set of initial color sample points and a set of test colors. Color properties of the printed test patches are measured. In certain examples, a gamut descriptor is identified from a plurality of gamut descriptors using the color properties of the test colors. Each gamut descriptor defines a set of up-sampling parameters for a particular color gamut. Measured color properties for the initial color sample points are up-sampled using the set of up-sampling parameters for the identified gamut descriptor to generate up-sampled data. In certain cases, the up-sampled data is used to generate a color mapping to be applied to print job data received by the printing system.

Abstract: A method of calibrating a printing system. Data defining a color mapping that maps a first set of n-dimensional color Input points to a corresponding second set of n-dimensional color output points, the color mapping representing a measured behavior of the printing system, is obtained. A smoothed mapping function of color input points that satisfies a predetermined optimization condition based on a mapping error between the smoothed mapping function and the color mapping is determined. The mapping error is a function of individual errors between outputs of the smoothed mapping function as applied to respective color input points in the first set of color input points and corresponding color output points from the second set of color output points as mapped from the respective color input points by the color mapping. The smoothed mapping function is used to calibrate the printing system.

Abstract: A method of obtaining a calibration factor for color calibration of a printing system. The method includes printing, using the printing system, a plurality of Neugebauer primaries (NPs) each defined by a respective Neugebauer primary area coverage (NPac) vector. For each of the NPs, an area coverage change of the NP is determined from a measurement of a visual property for the NP and a measurement of the visual property for a corresponding reference NP corresponding to the respective NPac vector. The calibration N factor for the printing system is obtained based on the area coverage change for respective NPs of the plurality of NPs.

Abstract: A method of detecting printing fluid mixing is provided. A test pattern for at least one printing fluid is printed with a printing device. The test pattern for the at least one printing fluid is scanned with a scanning device. Colorimetric data of the test pattern for the at least one printing fluid are obtained. Metric values are determined from the colorimetric data. A statistical analysis is performed on the determined metric values. Based on the statistical analysis, it is determined whether printing fluid mixing has occurred and where printing fluid mixing has occurred.

Abstract: A method is described in which sets of corresponding colorimetric values are obtained. In a set, a colorimetric value is associated with a device color. A number of device colors are selected according to the color differences between colorimetric values associated with the same device color. A color calibration pattern is elaborated for a printer to be calibrated using the selected device colors and calibration is performed using the sets of colorimetric values.

In one embodiment the method for sterilizing the dermal filler or injectable collagen material that is sensitive to radiation contains the steps of protecting the filler or material from radiation, and irradiating the filler or material with a suitable dose of radiation for a time and at a rate effective to sterilize the filler or injectable material. In a preferred embodiment the method for sterilizing the dermal filler or injectable collagen material that is sensitive to radiation includes the steps of a) freezing the filler or material at a temperature below its freezing temperature, which is generally below 0° C.

Abstract: A new and improved texture solution composition is disclosed that would be applied to decorative rock, concrete, lithocrete, and tile. Applying the texture solution to decorative rock, concrete, lithocrete and tile surfaces would add a distinct “glow-in-the-dark” characteristic to them. These surfaces with this texture solution applied would have the quality of phosphorescence, and would glow minutes after being exposed to bright light. In addition, the solution would glow when “black light” is shown on it.
