Abstract

Printing a graphic media product is described. The media product has an indicia marked on a media substrate. An installation of a supply of the media substrate is detected. A sensor is activated based on the detection of the installation. The activated sensor measures a width of the installed media substrate. A center position of the media substrate is computed based on the measured width. The marking of the indicia upon the media substrate is aligned relative to the computed center position of the media substrate.

Claims

a total of six hundred gaps between the marks;

activating a sensor, based on the detection of the installation;

measuring a width of the installed media substrate with the activated sensor;

computing a center position of the media substrate based on the measured width; and

marking the indicia upon the media substrate wherein the marking of the indicia is aligned relative to the computed center position of the media substrate.

2. The method as described in claim 1, further comprising the step of feeding the media substrate to a print head along a direction of the feeding and the printing of the graphic media product.

6. The method as described in claim 1 wherein the step of computing a center position of the media substrate based on the measured width comprises tracking a number of setting adjustments inputted in relation to configuring a setting corresponding to the measured width.

7. The method as described in claim 1 wherein the gaps comprise one or more of a shade or a brightness at least approximating a shade or a brightness of the media substrate, wherein the marks comprise one or more of a shade or a brightness darker than that of the gaps.

8. The method as described in claim 7 wherein one or more of the measuring the width of the installed media substrate with the activated sensor, or the computing the center position of the media substrate based on the measured width comprises counting at least one of the gaps or the marks.
