| titleOfInvention | Thermal head printer and process for printing substantially light-insensitive recording materials. |
| abstract | A thermal head printer for printing but not perforating ansubstantially light-insensitive thermographic material, the thermalnprinter comprising: a transport system having a transportndirection, n thermal heads, where n is an integer, each of thenthermal heads comprising an array of substantially rectangularnenergizable heating elements, the heating elements having a lengthnL n in the transport direction and a pitch P n between adjacentnheating elements, and a means for supplying electrical energy toneach of the substantially rectangular energizable heating elementsnin at least one of the thermal heads, the transport system beingncapable of transporting the light-insensitive thermographicnmaterial in contact or proximity with at least one of the thermalnheads, characterized in that at least one of the thermal headsncomprises heating elements for which L n /P n is between 0.25 and 0.88;na first process for printing a substantially light-insensitiventhermographic material with the above-described thermal headnprinter; a second process for printing a substantially light-insensitiventhermographic material at different printing speedsnwith a thermal head comprising heating elements without significantnvariation in image tone, characterized in that the length of thenheating elements in the transport direction of the substantiallynlight-insensitive thermographic material decreases with decreasingnprinting speed; and a third process for printing a substantiallynlight-insensitive thermographic material at different printingnspeeds with a different thermal head at each printing speed withoutnsignificant variation in image tone, characterized in that each ofnsaid different thermal heads comprises heating elements with andifferent length in the transport direction of the substantiallynlight-insensitive thermographic material and the length of thenheating elements in the transport direction of the substantiallynlight-insensitive thermographic material decreases with decreasingnprinting speed. |
