Items, including lost items or items out of place, can be located by attaching flickering LED's to them and moving about with a detector that registers the presence of the desired item or items by decoding the flickers. The flickers can substitute for, or augment, ordinary printed bar codes, and can use the same encoding so that the temporal pattern of flickering corresponds to the spatial pattern of black and white stripes in the printed bar code. The flickering items can be registered from a distance and from among a large group of other flickering items.

An image forming method comprises a step of reacting an ink containing a coloring material with a liquid composition containing fine particles reactive to the coloring material on a recording medium, where the reaction between the coloring material and the fine particles occurs in a liquid, the coloring material is adsorbed on the surfaces of the fine particles while keeping the monomolecular state as in the ink, and the fine particles having the coloring material on the surface aggregate each other. This method can provide images of high optical density and high color saturation, with less occurrence of white stripes in the image.

When thinning processing is performed to reduce the occurrence of black stripe caused by an overlap between scanning areas that is designed to prevent an end deviation from causing a white stripe, dots printed in a predetermined region by not only an ejection opening array subjected to the thinning processing but also other ejection opening arrays are counted so as to obtain their respective printing duties. Then, a color gamut is obtained based on the printing duties of the respective ejection opening arrays. Then, a thinning rate of the ejection opening array subjected to thinning processing is obtained by referring to a table corresponding to the color gamut, based on the printing duties of the respective ejection opening arrays obtained as above, and the thinning processing is performed. Accordingly, thinning processing can be performed which accurately reflects an amount of actual end deviation.

The invention discloses a method for carrying out image-text hiding according to an encrypted and converted phase position. The method includes the following steps: a Fresnel diffraction converting method is adopted to carry out encryption and conversion on an image-text to be hidden, so as to obtain a black-and-white stripe pattern namely a phase information pattern which is composed by the encrypted and converted phase position; on the basis of the phase information pattern, the image-text to be hidden is respectively hidden in an encoding card and a decoding card; when the encoding card and the decoding card are overlapped and aligned with each other, the hidden image-text can reappear. As the pattern of image-text information hidden in the cards is stripe-shaped, the overlapping and aligning operations of the encoding card and the decoding card can be easily realized when in reappearing; moreover, as different image-texts have different stripe shapes, the counterfeiting difficulty is enhanced and the anti-counterfeiting strength is enhanced as well. As the image-text information hidden on the decoding card or the encoding card presents the form of grating stripes of the phase information pattern, the effect of optical diffraction is achieved and the image-text hidden on the decoding card and the encoding card can reappear by laser. Anti-counterfeiting logos manufactured by the method for the two cards cannot be easily counterfeited, and the anti-counterfeiting strength is greatly enhanced.

Apparently, according to the MTF test chart card, the test method and the test device provided by the invention, when brightness of a display screen varies, difference between variation of a gray value of the black stripes and variation of the gray value of the white stripes is approximately equal to the difference between variation of the gray value of the black color block and variation of the gray value of the white block and is smaller, thus, a MTF value cannot vary with variation of the brightness of the display screen.

A printer that writes print data to the print buffer and runs the paper feed and printing process while receiving image data from a host computer desirably balances the speed of the paper feed and printing process and the speed of the conversion process to enable continuous printing so that white stripes do not appear in the printout. A print process run command and conversion format information specifying the conversion format for converting color block data in a print buffer 6 are temporarily stored. Based on the conversion format information stored in the receive buffer 4, whether the color block data can be transferred directly to the print buffer 6 and converted is determined (step S12). If direct transfer to the print buffer 6 is possible, the color block data sent after the conversion format information is directly transferred to the print buffer 6 without storing to the receive buffer 4, and the printing process is run according to the print process run command (step S16).
