Abstract: A printed substrate is provided. The printed substrate includes a plurality of color bars printed on a substrate, a space between each of the plurality of color bars and an image printed in the space between at least two of the color bars. An embedded color bar and a method of printing an embedded color bar are also provided.

Abstract: An annular cold plate with reflexive channels, and systems having such cold plates, are described herein.

Abstract: A printing sleeve in combination with a support device includes a printing sleeve having, a first end, a second end and an interior surface, and an inflation device acting on the interior surface of the printing sleeve when the printing sleeve is removed from a printing press. The combination advantageously permits the inflation device to act at both ends of the printing sleeve and also to make the combination portable.

Abstract: A method for embossing a cylindrical object such as a paint roller cover, especially using an apparatus that includes a shuttle and a rotatable shaft on the shuttle. The rotatable shaft includes two ends, with one end accepting a paint roller cover and with the other end being toothed for engagement with a gear rack. As the rotatable shaft is drawn in one direction by the shuttle, the toothed end engages the gear rack and rotates the rotatable shaft, thereby also rotating the paint roller cover. As the paint roller cover rotates, it is drawn by the shuttle over a die transfer plate having a design formed therein, and such design is transferred to the paint roller cover. The die transfer plate is heated to the desired temperature, and the speed of the shuttle is controllable so that time and temperature is controlled. Another controlled parameter is pressure.
