20080211866 | Uv Inkjet Printing of Vision Control Panels - This invention concerns vision control panels and a method of UV inkjet printing vision control panels. A substantially imperforate light permeable material is partially printed with a ‘print pattern’ comprising a base layer and a design layer comprising a design colour layer. The method is limited to digital UV inkjet printing of all the superimposed layers required to make such panels. Optionally, the method uses a novel printhead array with a novel order of ink colour supply and/or novel software to enable the required build-up of ink layers, for example of black, optional silver, white, cyan, magenta, yellow and process black colours. Printing is preferably arranged so that the base layer and design colour layer are printed in the minimum number of passes of the printhead assembly of the digital UV inkjet printer to achieve the desired effect, preferably in one pass of the printhead assembly. | 09-04-2008 |

An acid value of the pigment dispersing resin is 160 or more and 240 or less. The inkjet recording liquid is discharged from a recording head of the inkjet recording device. Even when nozzles of the recording head become clogged due to drying or thickening of the inkjet recording liquid, the nozzle clogging can be easily resolved with a purge operation and wiping operation of the recording head by a wipe unit. Thus, it is possible to reduce an overconsumption of the recording liquid due to the foregoing purge operation. | 01-26-2012 |
