A graphic arts die assembly includes a die carrier plate, a die, and a die adjuster. The die is adjustably supported on the die carrier plate. The die presents an outer margin and an engraved surface within the outer margin. The die further presents an adjuster surface that extends transversely relative to the engraved surface. The die adjuster shiftably engages the adjuster surface, with shifting movement of the die adjuster causing relative movement between the die and the die carrier plate.

A manual craft cutting machine comprises a housing, a template, a press roller, a retainer, a backing plate, and a drive mechanism. The press roller is composed of a first press roller and a second press roller. The press roller is rotated under restriction of the retainer. The retainer comprises a positioning retainer and a sliding retainer. The positioning retainer is provided with a slide groove. The sliding retainer is inserted in the slide groove and movable along the slide groove. The sliding retainer comprises a first sliding retainer rotatably connected with the first press roller and a second sliding retainer rotatably connected with the second press roller. The manual craft cutting machine further comprises a press roller spacing adjustment mechanism. The press roller spacing adjustment mechanism comprises a shift adjusting mechanism for adjusting a large spacing between the press rollers and a fine adjustment mechanism for adjusting a fine spacing between the press rollers. The shift adjustment mechanism drives the first sliding retainer to move along the slide groove, and the fine adjustment mechanism drives the second sliding retainer to move along the slide groove, so that the spacing between the press rollers can be quickly and largely adjusted according to the needs, and a fine spacing adjustment can be achieved according to the needs.

A graphic arts support assembly is operable to be used with a graphic arts plate assembly in a press. The graphic arts support assembly and the plate assembly are configured for removable association with a lift mechanism including a shiftable lift element. The support assembly includes a graphic arts magnetic support structure operable to removably support the graphic arts plate assembly. The magnetic support structure includes a support plate, a magnet fixed relative to the plate, and an alignment element projecting from the support plate. The support assembly is operable to be mounted on the lift mechanism so that the lift element is aligned with a lift opening of the support plate, with the lift element shiftable through the lift opening to locate at least part of the graphic arts plate assembly away from the support plate.
