According embodiments of the present disclosure, a water-based ink set for ink-jet recording is provided. The ink set may contain a black ink, a cyan ink, a magenta ink and a yellow ink. Each ink may contain a polyoxyethylene alkyl ether sulfonate.

A printing apparatus and a printing method are provided by which information printed on a printing medium can be used to appropriately control an image printing while allowing the entire printing apparatus to have a simpler and smaller configuration. An image is printed on a conveyed sheet by yellow, black, cyan, and magenta inks ejected from printing heads. The yellow ink ejected from the printing head is used to print an image in which information for sensing a sheet conveying amount is embedded by an electronic watermark. The information is read by a sensor unit. Based on the reading result, a printing control is performed. The printing head to eject yellow ink is positioned at an upstream side in a sheet conveying direction than the sensor unit. The printing head to eject black ink is positioned at a downstream side in the sheet conveying direction than the sensor unit.

The invention provides an LED color adjusting lamp which comprises a circuit board, a current controller arranged on the circuit board and a plurality of LED light-emitting modules, wherein the plurality of LED light-emitting modules are electrically connected to the current controller through the circuit board; each of the plurality of LED light-emitting modules comprises a yellow LED light emitting unit, a carmine LED light emitting unit and a cyan LED light emitting unit. A color adjusting effect of the color mixing unit is achieved by controlling the intensity of yellow light, carmine light and cyan light sent by the yellow LED light emitting units, the carmine LED light emitting units and the cyan LED light emitting units by means of the current controller. The LED color adjusting lamp is low in power consumption and has a relatively good color adjusting effect while saving the energy consumption.
