Claims
- 1. A thermal transfer printing method comprising the steps of:
- applying a coat of colored material by thermal transfer to the entire surface of a record medium web to form thereon a coating of a specific background color before recording of images thereon is performed;
- superposing the record medium web over a carrier web having a coat of dry ink meltable by heat applied to its surface and pressing them together, with the coating of a specific background color facing the carrier web, as they are fed between a printhead including a plurality of individual thermal elements and a platen roller; and
- selectively energizing the thermal elements to record images on the record medium web by thermal transfer of the coat of dry ink from the carrier web onto selected portions of the record web.
- 2. A thermal transfer printing method as in claim 1, wherein said carrier web bears a plurality of sectors of color image forming material including a yellow sector, a magenta sector and a cyan sector each having a recording capacity for one page and arranged in end-to-end relation in the direction in which the carrier web is fed, and a sector of a background color applying material also having a recording capacity for one page and also arranged in end-to-end relation to the plurality of the sectors of color image forming material, whereby a coat of a background color material can be applied to the entire surface of a portion of the record medium web corresponding to one page, by thermal transfer from said sector of a background color applying material of the carrier web, before color images are formed on said portion by using said sectors of color image forming material.
- 3. A thermal transfer printer comprising:
- means for supplying a transfer sheet having groups of sectors, wherein one of the sectors in a group bears a background material of a specific background color material and the other sectors in the same group bear materials of respective different image colors;
- means for supplying a record medium which comprises a succession of copy area surfaces; and
- means including a thermal head for transferring the specific background color material of one group of sectors by thermal transfer from the transfer sheet to an entire copy surface area of the record medium, and for transferring thereafter selected portions of at least one of the materials of said different image colors of the same group of sectors by thermal transfer from the transfer sheet to the same copy surface area of the record medium.
- 4. A thermal transfer printer as in claim 3 in which the means for transferring comprise means for transferring the background color material from one group of sectors of the transfer sheet to one entire copy surface area of the record medium and transferring a plurality of different color materials from the same group of sectors to the same copy surface area of the record medium.
- 5. A thermal transfer printer as in claim 4 in which the transfer sheet is in the form of a transfer web and the record medium is in the form of a record web.
- 6. A thermal transfer printer comprising:
- means for supplying a record medium having at least one copy surface;
- means for coating the entire copy surface by thermal transfer printing with a coating of a specific background color;
- means for supplying a transfer sheet having a group of sectors each of which comprises a material of a different image color;
- means including a thermal printhead for transfering by thermal printing from the transfer sheet to the copy surface coated with said coating of a specific background color, material of at least one of said image colors to form a color image thereon.
- 7. A thermal transfer printer as in claim 6 in which the group of sectors comprises a sector of a material of said specific background color and the means for coating comprises a part of said means for transferring by thermal printing from the transfer sheet to the copy surface.
