Definitions

  • the present invention generally pertains to a printing system and a method for forming a blouse in a web medium.
  • Printing system for web-based media such as roll-to-roll printers, are known to comprise a buffer region or blouse forming region between the print surface below the image forming unit and the take-up roller for winding the printed web medium onto a roll.
  • the blouse is a free hanging U-shaped curve in the web medium between the print surface and the take-up roller.
  • This blouse provides a buffer decoupling the section of the medium below the image forming unit from the pulling force from the driven take-roller. Thereby, the medium is not displaced while being printed on.
  • the blouse is generally formed under the influence of gravity by basically allowing a section of the web medium to hang free in the buffer region.
  • the blouse Upon feeding additional web medium into the buffer region, while temporarily reducing the amount of medium leaving the buffer region, the blouse is formed to the desired size. This, however, requires sufficient flexibility of the web medium, such that it deforms into the desired blouse shape under the influence of gravity. Certain media types possess a stiffness too great to allow such deformation. These stiff media do in a limited manner curve downwards into the buffer region, but due to their large stiffness, the upstream section of the web medium below the image forming unit is consequently leveraged upward (see Fig. 3 ).
  • a disadvantage of the known web printing system is their inability for forming a blouse in stiff media, limiting the media versatility of these systems.
  • a printing system for web media according to claim 1 comprises:
  • the printing system comprises a buffer region suitable for media of "average” stiffness.
  • the printing system is suitable for stiffer media by application of the pressing device.
  • a stiff medium may be positioned over the buffer region in a commonly applied manner for media of "average” stiffness.
  • the pressing device for example a page-wide roller, is then lowered from the first position above the web medium onto the web medium. Thereby, the stiff web medium is deformed and pressed into the buffer zone.
  • the pressing device moves downward until it engages the locking device on the guide, which prevents the pressing device from moving beyond the second position. In this manner, an initial blouse-shaped curve is formed in the stiff web medium.
  • the transport system is then controlled to feed a desired or predefined amount of the stiff medium into the buffer region.
  • the transport system preferably further limits or reduces the transport of the stiff web medium out of the buffer region.
  • the initial curve expands away from the pressing device in the second position.
  • the initial curve is evolved into a blouse, which hangs freely in the buffer region without contacting the pressing device.
  • the initial curve formed by the pressing device provides sufficient deformation of the web medium to expand into a blouse without affecting the position of the medium upstream of the buffer region. This provides an adequate decoupling of medium being printed on from the forces of the take-up roller.
  • the pressing device allows the buffer region to be positioned near the print surface, resulting in a compact printing system. Additionally, the pressing device increases the media versatility, as it allows for printing on stiffer media. Thereby, the object of the present invention is achieved.
  • the printing system according to the present invention further comprises a controller configured for:
  • the printing system according to the present invention further comprises a controller configured for:
  • controller is further configured for:
  • the pressing device is further moveable to a third position positioned in the lower zone in the buffer region below the second position.
  • the printing system comprises an actuatable transport roll upstream of the print surface for controllably pushing the web medium over the print surface.
  • Certain flexible or weak media type do not allow for such "pushing" transport.
  • the weak media are generally transported under continuous tension from the take-out roller to the take-up roller, such that these media are pulled through the printing system.
  • the pressing device is configured as a tensioning device for forming a U-shaped curve in the weak medium.
  • the guide is configured for free vertical movement of the roller in the third position during printing. The pressing device then under the influence of gravity provides a tensioning force on the weak medium. No locking device is then required at the third position. By allowing the guide to extend over the height of the buffer region, the media versatility can thus be increased further.
  • the guide comprises translating means for allowing the pressing device to translate substantially unimpeded or freely along the guide under the influence of gravity. This allows the pressing device to move downwards under the influence of gravity. No additional actuator is then required, reducing the costs of the printing system.
  • the translating means may e.g. comprise sliders or vertically extending racks, wherein the roller comprises a pair of corresponding pinions.
  • the translating means are configured for maintaining the pressing device in a horizontal orientation during its vertical movement. It will be appreciated that dampening means may be provided to reduce the speed or acceleration of the unimpeded or free descend of the pressing device for reasons of safety.
  • the locking device when engaged, limits the movement of the pressing device along the guide between the first and second position.
  • the locking device is preferably configured to rotatably secure the pressing roller in the second position.
  • the pressing device may freely travel over the full length of the guide, for example to the third position for the tensioning of weak media.
  • the pressing device is a roller provided between a pair of a parallel guides for directing the roller from the first position to the second and/or third position.
  • the locking device is configured to prevent the pressing device from descending below the second position under the influence of gravity.
  • An additional holding device may be provided at the first position to locking device the pressing device above the transport path.
  • the third position does not comprise a holding device such that the pressing device due to gravity exerts a tensioning force on the web medium.
  • the guide is configured such that the pressing device moves is substantially free along the guide with the exception of the second position when the locking device is engaged.
  • the printing system according to the present invention further comprises a controller configured for:
  • the printing system according to the present invention further comprises a locking sensor for detecting engagement of the locking device, wherein the controller is further configured for:
  • the locking sensor detects whether the locking device is engaged with the guide by detecting whether or not the locking device is in its locking position on the guide. In the locking position, the locking device prevents the pressing roller from descending below the second position.
  • the sensor provides information regarding the state of the locking device, such that, in the second print mode wherein the presence of the pressing roller is required, the controller prevents printing from commencing when the locking device is detected to be absent from its locking position. In the third print mode, the pressing roller is required to descend to the third position.
  • the controller starts the print job, when the sensor detects that the locking device is not present at its locking position, such that the pressing device may travel unimpeded to the third position.
  • the printing system according to the present invention further comprises a transport surface plate moveable between:

  • the locking device may be a clamp or insert on which the pressing roller is supported in the second position.
  • the locking device is positioned at its locking position on the guide. In the locking position, the locking device prevents the pressing device from descending below the second position. The blouse is then formed below the pressing device in the second position.
