Abstract

Abstract In printing apparatus of the type which includes a ribbon having a backing layer and an ink donor layer supported on the backing layer, wherein the apparatus includes a first thermal printhead for transfer printing a first ink pattern from the ink donor layer to the backing layer at a first printing station, a second thermal printhead for transfer printing a second ink pattern from the ink donor layer to a workpiece at a second printing station, there is provided a process including the steps of: sensing a letter being fed to the second printing station; starting feeding the ribbon; starting printing at the first printing station; moving the second printhead from a non-printing position to a printing position; starting printing at the second printing station; stopping printing at the first and second printing stations; stopping feeding the ribbon; and moving the second printhead from the printing position to the non-printing position.

Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 157 words
In printing apparatus of the type which includes a ribbon having a backing layer and an ink donor layer supported on the backing layer, wherein the apparatus includes a first thermal printhead for transfer printing a first ink pattern from the ink donor layer to the backing layer at a first printing station, a second thermal printhead for transfer printing a second ink pattern from the ink donor layer to a workpiece at a second printing station, a process comprising the steps of: a. sensing a letter being fed to the second printing station; b. starting feeding the ribbon; c. starting printing at the first printing station; d. moving the second printhead from a non-printing position to a printing position; e. starting printing at the second printing station; f. stopping printing at the first and second printing stations; g. stopping feeding the ribbon; and h. moving the second printhead from the printing position to the non-printing position.
Claim 2
Dependent Claim 157 words
In printing apparatus of the type which includes a ribbon having a backing layer and an ink donor layer supported on the backing layer, wherein the apparatus includes a first thermal printhead for transfer printing a first ink pattern from the ink donor layer to the backing layer at a first printing station, a second thermal printhead for transfer printing a second ink pattern from the ink donor layer to a workpiece at a second printing station, a process comprising the steps of: a. sensing a letter being fed to the second printing station; b. starting feeding the ribbon; c. starting printing at the first printing station; d. moving the second printhead from a non-printing position to a printing position; e. starting printing at the second printing station; f. stopping printing at the first and second printing stations; g. stopping feeding the ribbon; and h. moving the second printhead from the printing position to the non-printing position.
Claim 3
Dependent Claim 31 words
The process according to claim 1, wherein step (b) includes the step of starting a printing cycle count, and wherein step (h) includes the step of stopping the printing cycle count.
Claim 4
Dependent Claim 12 words
The process according to claim 1, wherein step (d) follows step (c).
Claim 5
Dependent Claim 28 words
The process according to claim 1, wherein step (d) follows step (c) after a time delay during which the ribbon is fed between the first and second printheads.
Claim 6
Dependent Claim 21 words
The process according to claim 1, wherein step (d), follows step (c) when the ribbon is at the second printing station.
Claim 7
Dependent Claim 19 words
The process according to claim 1, wherein step (d) follows step (c) upon lapse of a predetermined time interval.
Claim 8
Dependent Claim 20 words
The process according to claim 2, wherein step (d) follows step (c) upon lapse of a predetermined printing cycle count.
Claim 9
Dependent Claim 12 words
The process according to claim 2, wherein step (d) follows step (c).
Claim 10
Dependent Claim 26 words
The process according to claim 1, wherein step (c) includes the step of printing an ink pattern in the form of an outline of an indicia.
Claim 11
Dependent Claim 23 words
The process according to claim 1, wherein step (c) includes the step of printing an ink pattern in the form of an indicia.
Claim 12
Dependent Claim 26 words
The process according to claim 1, wherein step (e) includes the step of printing an ink pattern in the form of an outline of an indicia.
Claim 13
Dependent Claim 23 words
The process according to claim 1, wherein step (e) includes the step of printing an ink pattern in the form of an indicia.
Claim 14
Dependent Claim 43 words
The process according to claim 9, wherein step (e) includes the step of transfer printing to the workpiece all ink remaining on the backing layer of the ribbon whereby the ink pattern printed on the workpiece is in the form of the indicia.
Claim 15
Dependent Claim 46 words
The process according to claim 10, wherein step (e) includes the step of transfer printing to the workpiece all ink remaining on the backing layer of the ribbon, whereby the ink pattern printed on the workpiece is in the form of an outline of the indicia.
Claim 16
Dependent Claim 25 words
