| 20150339799 | TECHNIQUES FOR OPTIMIZING STENCIL BUFFERS - One embodiment sets forth a method for associating each stencil value included in a stencil buffer with multiple fragments. Components within a graphics processing pipeline use a set of stencil masks to partition the bits of each stencil value. Each stencil mask selects a different subset of bits, and each fragment is strategically associated with both a stencil value and a stencil mask. Before performing stencil actions associated with a fragment, the raster operations unit performs stencil mask operations on the operands. No fragments are associated with both the same stencil mask and the same stencil value. Consequently, no fragments are associated with the same stencil bits included in the stencil buffer. Advantageously, by reducing the number of stencil bits associated with each fragment, certain classes of software applications may reduce the wasted memory associated with stencil buffers in which each stencil value is associated with a single fragment. | 11-26-2015 |
| 20160039236 | DECAL PRINTING PAPER FOR CERAMICS - A decal printing paper for ceramic surfaces has a base paper coated with a water-soluble release layer, an image transfer layer made of liquid cover coat with glass/ceramic flux added, and a printed image layer. The glass/ceramic flux contains glass frit with a relatively low melting point to provide a one-step printing paper with a glass/ceramic flux that delivers the required adhesion, as well as reducing the firing temperature. The image transfer layer can also include a dye colorant to provide a visual indication of a functional characteristic of the decal printing paper. | 02-11-2016 |
| 20160052254 | METHOD FOR PRODUCING A PATTERNED STEEL PLATE BY USING ROLLER-COATING PRINTING AND SCREEN PRINTING - A method for producing a patterned steel plate by using roller-coating printing and screen printing, and a ground color pattern produced can be more accurate and a thicker and solider printing layer with a stronger stereo perception can also be obtained by using the roller-coating printing and screen printing, meanwhile in roller coating section, a servo control system is further included to control the rotate speed of each roller of the roller coating equipment and the preset time, thus ensuring that the actual roller surface linear velocity is consistent with the process rotation speed, so there is no need to stop the line for adjusting in the production process, thus increasing the production efficiency. | 02-25-2016 |
| 20160052321 | METHOD FOR PRODUCING A PATTERNED INSULATION BOARD USED FOR EXTERIOR WALL OF BUILDING BY USING SCREEN PRINTING - A method for producing a patterned insulation board used for exterior wall of building by using screen printing, and the patterned insulation board including a metal veneer, a substrate an insulation layer between the metal veneer and the substrate, and the method including a step of screen printing the metal veneer, wherein, a flattening device is arranged at a bottom of the printing table, and used to flatten a surface of metal veneer, prior to the screen printing. The flattening device makes the scraper transfer ink by uniform force, which reduces printing difficulties overcome the printing difficulty. | 02-25-2016 |
| 20160068746 | Photochromic Inks - Metal deco ink formulations are improved by the use of fluorescent dyes, UV-absorbing dyes and/or IR-absorbing dyes. These may be premixed with a phenol-formaldehyde resin without microencapsulation to protect the dye from other ink ingredients that have chemistries which are incompatible with that of the dye, in order to obtain photochromic ink formulation with a good shelf life. | 03-10-2016 |
| 20160082714 | METHOD FOR PRODUCING A PATTERNED STEEL PLATE WITH A SINGLE-GROUND COLOR BY USING ROLLER-COATING PRINTING AND SCREEN PRINTING - A method for producing a patterned steel plate with a single-ground color by using roller-coating printing and screen printing, and a ground color pattern produced can be more accurate and a thicker and solider printing layer with a stronger stereo perception can also be obtained by using the roller-coating printing and screen printing, meanwhile in roller coating section, a servo control system is further included to control the rotate speed of each roller of the roller coating equipment components and the present time, thus ensuring that the actual roller surface linear velocity is consistent with the process rotation speed, so there is no need to stop the line for adjusting in the production process, thus increasing the production efficiency. | 03-24-2016 |
