Abstract: Method and device to improve the printing quality and thereby the readability of the print of electrographic printers. An information carrier is brought into electric cooperation with at least one screen grid shaped electrode matrix, which by control in accordnace to the configuration desired pattern at least partly opens and closes passages through the matrix by galvanic connection to this to at at least one voltage source. Through thus opened passages electrical fields are exposed for attraction of pigment particles against the information carrier. This is locateable between said electrode matrix and a background electrode. This contains counter electrodes (8,8') in the form of galvanically separated sections, which are suibstantially symmetrically located above respective line of passages in the electrode matrix.

Abstract: In a construction of a ski having patterns visible on the bottom, the sole board is made up of a transparent polyethylene resin sheet and a thermoplastic synthetic resin composite sheet sandwiched between the polyethylene resin sheet and the main body of the ski, the patterns being formed on the mating surface of the composite sheet with the polyethylene resin sheet. In manufacturing, a composite film having patterns printed thereon is successively combined with a polyethylene resin sheet by pressure fusion at high temperature. Reduced thickness of the sole board with high masking effect, omission of the wet system painting conventionally used for masking layer formation, and employment of the economically advantageous photogravure printing of the patterns can be expected.
