Described herein are printing ink compositions suitable for printing of microwavable flexible packaging. The printed black ink exhibits low microwave energy absorption, thus minimizing the risk of charring, arcing, ignition, distortion or burning during microwave heating processes. Nitrocellulose resin, a solvent, a polyurethane resin, and a carbon black pigment having at least one of an imaginary permittivity of ≤3, preferably ≤2, and a surface oxygen content of 1 wt % to 3 wt %, preferably 1.5 wt % to 2.5 wt % are among the components of the printing ink compositions. Also described is packaging suitable for exposure to microwave energy upon which the inks have been printed.

A method of forming solder paste on an object is provided. The method includes providing a multilayered stencil, each stencil layer having an aperture formed therethrough from a top surface of the respective stencil layer to a bottom surface of the stencil layer. The method also includes applying the stencil to a surface of the object. The method also includes filling a void space formed by a combination of the apertures in the stencil layers with solder paste. The method also includes removing the stencil layers in a sequential manner to leave the solder paste.

A method of producing a solid soap containing at least one image embedded within the solid soap includes printing a printed image on a base layer of solid soap, applying molten soap to the printed base layer, and allowing the soap to harden so as to embed the image within the solid soap. The image can be a high-resolution image and can be printed on the base layer of solid soap using a flatbed printer. The soap can include a background layer against which the image is visible.

Provided in one example herein is a method of printing. The method includes disposing onto a transfer paper an ink composition to form thereon an image, the ink composition including pigments and latex particulates. The method includes transferring the image from the imaged transfer paper onto a substrate comprising fabric by a lamination process. The lamination process includes: laminating together the substrate, the imaged transfer paper, and a release paper, whereby the image is transferred from the transfer paper onto the substrate.
