Abstract

The present ink proofer arrangement (100) generates consistent and reliable ink draw downs irrespective of the size of the substrate or the user preparing the ink sample. In one example embodiment, an ink proofer arrangement is adapted to be used with an ink proofer tool (1), the ink proofer tool including an ink transfer roller. The ink proofer arrangement further includes a cylindrical rollern (106) and a drive motor (222) adapted to rotate the roller. In addition, a first movable mounting assembly is included that retains the ink proofer tool adjacent to and in a non-contact position with the roller. The proofer arrangement further includes a first variable pressure assembly coupled to the mounting assembly and adapted to move the ink proofer tool into a contact with pressure position with the roller and further adapted to move the ink proofer tool into the non-contact position, wherein the transfer roller is adapted to transfer ink to a substrate that is inserted between the roller and the transfer roll of the ink proofer tool when the drive motor is engaged.

Claims (20)

1. An ink proofer arrangement adapted to be used with an ink proofer tool, the ink proofer tool including an ink transfer roller, comprising:
a cylindrical roller;
a drive motor adapted to rotate the roller;
a first movable mounting assembly adapted to retain the ink proofer tool adjacent to and in a non-contact position with the roller; and a first variable pressure assembly coupled to the mounting assembly and adapted to move the ink proofer tool into a contact with pressure position with the roller and further adapted to move the ink proofer tool into the non-contact position, wherein the transfer roller is adapted to transfer ink to a substrate that is inserted between the roller and the transfer roll of the ink proofer tool when the drive motor is engaged.
2. An ink proofer arrangement as in claim 1, further comprising:
a second movable mounting assembly adapted to support the roller; and a second variable pressure assembly coupled to the second mounting assembly and adapted to move the roller into a contact position with the ink proofer tool and to move the roller to a non-contact position with the ink proofer tool.
3. The ink proofer arrangement of claim 1, wherein the first variable pressure assembly is adapted to move the ink proofer tool into the contact with pressure position with the roller when the drive motor is engaged and to move the ink proofer tool into the non-contact position when the drive motor is disengaged.
4. The ink proofer arrangement of claim 2, wherein the second variable pressure assembly is adapted to move the roller into a contact position with the ink proofer tool when the drive motor is engaged and to move the roller to a non-contact position with the ink proofer tool when the drive motor is disengaged.

12. An ink proofer arrangement of claim 11, wherein the mounting assembly is configured to be movable, the arrangement further comprising a second variable pressure assembly coupled to the mounting assembly and adapted to move the ink proofer tool into a contact position with the roller when the drive motor is engaged and to move the ink proofer tool into the non-contact position with the roller when the drive motor is disengaged.
13. The ink proofer arrangement of claim 11, wherein the first variable pressure assembly coupled to the movable support assembly and adapted to move the roller into the contact position with the ink proofer when the drive motor is engaged and to move the roller into a non-contact position with the ink proofer tool when the drive motor is disengaged.
14. The ink proofer arrangement of claim 12, wherein the second variable pressure assembly is adapted to move the ink proofer tool into the contact position with the roller when the drive motor is engaged and to move the ink proofer tool into the non-contact position with the roller when the drive motor is disengaged.
15. The ink proofer arrangement of claim 11, wherein the drive motor is further adapted to rotate the roller at variable speeds.
16. The ink proofer arrangement of claim 15, wherein speed reduction for the drive motor is selected from the group consisting of a belt and pulley arrangement, direct or indirect gear reduction and a variable speed mechanical drive.
17. The ink proofer arrangement of claim 11, wherein the first mounting assembly actuates the drive motor when pressure is applied to thereto.
18. The ink proofer arrangement of claim 11, wherein the first variable pressure assembly is actuated via a lever.
19. The ink proofer arrangement of claim 11, wherein the mounting assembly further comprises a universal ink proofer holder having a channel and notch therein for retaining the ink proofer tool.
20 20. The ink proofer arrangement of claim 11, further comprising a substrate roll support assembly mounted adjacent the mounting assembly.
