Abstract
A method for substantially removing “roll-set curl” in a rolled print medium. Roll-set curl, as the name implies, may be defined as the “memory” a print medium has which causes the print medium to tend to return to the shape it had while on the core, once the print medium is unrolled. Additionally, a method for printing on both sides of a print medium in which a roll-set curl has been substantially removed. In one respect, according to a preferred embodiment, a take-up reel is utilized to substantially remove the roll-set curl.
Claims4
A method of removing roll-set curl from a print medium rolled on a core utilizing a large format printer equipped with a take up reel (“TUR”), the method comprising:
- activating a TUR having a first core;
- loading the rolled print medium into the large format printer;
- advancing the rolled print medium through the large format printer until a front edge of the rolled print medium is adjacent to the TUR;
- attaching the front edge of the rolled print medium to the first core of the TUR;
- substantially removing roll-set curl from the rolled print medium by rotating the first core of the TUR in a direction substantially opposite a direction of the print medium roll to substantially wind the rolled print medium on to the first core of the TUR without printing on the rolled print medium;
- removing the first core of the TUR and the print medium wound on the first core;
- placing the first core of the TUR and the wound print medium onto a spindle of the large format printer, such that a first side of the rolled print medium is positioned to be printed upon by the large format printer;
- sending a first plot stream to the large format printer;
- placing a second core into the TUR;
- winding the wound print medium from the first core to the second core;
- and
- printing an image corresponding to the first plot stream on the first side of the rolled print medium while winding the wound print medium from the first core to the second core.

- placing a third TUR core into the TUR;
- attaching the front edge of the print medium to the third TUR core;
- sending a second plot stream to the large format printer;
- winding the print medium onto the third TUR core;
- and
- printing an image corresponding to the second plot stream on a second side of the rolled print medium while winding the wound print medium from the second core to the third core.
