A printing apparatus configured to print a can body includes: a plurality of printing plates; a blanket; a blanket transfer device configured to transfer inks on the plurality of printing plates to the blanket; and a can body transfer device configured to transfer the inks transferred to the blanket to the can body. The blanket transfer device transfers the inks such that at least part of an ink transferred from one printing plate is superimposed onto at least part of inks in other colors transferred from other printing plates.

A redundantly printed security-enhanced document, printing method and system ensure the meaning of the information imparted by variable indicia printed by redundant printing on the document with removable scratch-off coatings. By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved. Additionally, inverted color indicia countermeasures to pinprick attacks are also disclosed. The redundantly printed document, methods and systems enhance the overall appearance of the redundantly printed document, and reduce possible consequences resulting from misprinted variable indicia. The resultant printed process color indicia maintains a grayscale equivalent level of a process color greater than or equal to the measured grayscale equivalent level of the substrate surface plus an additional contrast delta of 15%.

A printing apparatus configured to print an image on a can body includes: a blanket transfer device configured to transfer ink on a plurality of printing plates to a blanket; and a can body transfer device configured to transfer the ink having been transferred on the blanket to the can body to print the image on the can body. The plurality of printing plates include a first printing plate and a second printing plate to print a specified image of the image. The first printing plate is configured to print a border image which is a border part of the specified image, and the second printing plate is configured to print a vicinity of the border image in the specified image.

An adhesive gel nail includes: an adhesive layer; a color base layer formed on a top of the adhesive layer; a color printing layer formed on a top of the color base layer; a gel coating layer formed on a top of the color printing layer; and a decorative layer formed on a top of the gel coating layer, wherein a lower surface of the decorative layer is disposed on the color base layer.

A substrate is printed with front side and back side markings in a first color ink. The front side when viewed with reflected light includes a first marking printed in a first saturation and a first symbol printed in the first saturation. The back side when viewed with reflected light includes: a second marking printed in a second saturation; a second symbol printed in the second saturation; a third marking printed in the first saturation; and a third symbol printed in the first saturation. The first marking, the second marking, and the third marking are printed to provide an interlocking pattern of low saturation color and high saturation color when viewed with transmitted light. The second symbol is visible, and the first symbol and the second symbol are not distinguishably visible, when viewed with transmitted light.

A substrate is printed with front side and back side markings. The front side when viewed with reflected light includes: a first marking printed with a first gradient of two colors; a second marking printed with a second gradient of two colors; a first symbol printed with a third gradient of two colors; a second symbol printed with a fourth gradient of two colors; a third symbol printed with a fifth gradient of two colors; and a fourth symbol printed with a sixth gradient of two colors. The back side when viewed with reflected light includes: a third marking printed with the fourth gradient; a fourth marking printed with the third gradient; a fifth symbol printed with the second gradient; a sixth symbol printed with the first gradient; a seventh symbol printed with the sixth gradient; and an eighth symbol printed with the fifth gradient.

Examples are directed toward a substrate offset printed with front side markings on a first side and back side markings on a second side. The front side markings and the back side markings have dimensions in a micrometer range. The front side when viewed with reflected light comprises first portions of a plurality of characters. The back side when viewed with reflected light comprises second portions of the plurality of characters. The first portions and the second portions are printed, when viewed with transmitted light, to show the plurality of characters as whole characters having dimensions in the micrometer range.
