A method for measuring Side 1 to Side 2 image on paper misregistration includes using a series of lines printed on both sides of a substrate, such as, paper. The paper is passed in front of an in-line spectrophotometer or densitometer. The amount of image 'show through' is measured and correlated to an amount of misregistration.

Method of correlating image misregistration

An apparatus () having a peripheral interface port hub and secure thumb device enclosure is disclosed. The apparatus can include a frame () and an external peripheral interface upstream port () coupled to the frame. The external peripheral interface upstream port can be configured to couple the apparatus to a host external peripheral interface port, where the host external peripheral interface port can be configured to couple a host device to a peripheral external to the host device. The apparatus can include a plurality of external peripheral interface downstream ports (-) coupled to the frame, where each external peripheral interface downstream port can be configured to couple the apparatus to an external peripheral interface thumb device, where the external peripheral interface thumb device can be configured to be coupled to a printing apparatus. The apparatus can include a cover () configured to cover external peripheral interface thumb devices coupled to the plurality of external peripheral interface downstream ports.

A printing system includes a first image applying component configured for applying one or more primary colorants to print media for rendering an image. A second image applying component is configured for applying a second colorant, such as black colorant, to print media for rendering an image. A first pathway conveys print media between the first image applying component and the second image applying component. A second pathway bypasses the first image applying component for conveying print media which is printed by the second image applying component. Where an image is to be rendered with the primary colorants and optionally also black, the print media is directed on the first pathway to both the first and second image applying components. Where an image is to be rendered only with black colorant, the print media may be directed to the second image applying component via the bypass pathway. In this way, during black printing, the first image applying component can be placed in a standby mode.
