Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は主に銀行券、パスポート、証券類、カード類な
どの偽造防止、変造防止が、要求されるものに利用され
ている印刷方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to a printing method which is used for banknotes, passports, securities, cards and the like for which forgery prevention and alteration prevention are required. It is a thing.

と真券との判別が容易となり、偽造防止策として有効で
ある。[Prior Art] Banknotes, passports, securities, cards, etc. are required to be resistant to forgery or alteration due to their uses and properties. Known visual forgery prevention measures include a latent image pattern, a pattern utilizing the density of halftone dots, and a moire pattern. A printed matter incorporating these patterns makes it easy to distinguish between a forged ticket and a genuine ticket, and is effective as a forgery prevention measure.

な点又は線からなる模様として潜像模様を刷込んで施し
た印刷物である。The above-mentioned printed matter is a printed matter obtained by imprinting a latent image pattern as a pattern composed of fine dots or lines such as halftone dots, parallel lines, and other tint block patterns.

を、同一の印刷物に印刷する場合に、精巧な模様の刷り
合せを完全に行うとは不可能であった。The printed matter incorporating the anti-counterfeiting measures described in the related art requires a high plate surface mounting accuracy, and thus the printing operation becomes very difficult. Also, when printing intaglio printing, which requires very high printing pressure, and offset printing, which can be printed with low printing pressure, on the same printed matter, it was impossible to perfectly perform delicate pattern matching. .

る。The present invention is a completely different method from the method for obtaining these prints, and enables intaglio printing that requires a very high printing pressure and offset printing that can be printed at a low printing pressure on the same substrate, and complete printing of delicate patterns. It is an object of the present invention to provide a new printing method capable of performing precise printing.

刷方法である。The present invention uses a combination printing machine of offset and intaglio printing machine or a printing machine in which an intaglio printing unit is installed in a part of the offset printing machine, and after dry offset or wet offset printing a tint block pattern consisting of halftone dots or fine lines, the ink A combination that immediately prints a solid or continuous pattern on the tint block pattern by the intaglio printing method that requires very high printing pressure, while the ink is not yet dried, and immediately uses an intaglio ink containing a hydrophilic solvent such as ethylene glycol ester. The printing method.

表面のみ凹版インキが転移するので、非常に高い印刷圧
力を要求される凹版印刷と、低い印刷圧力で印刷できる
オフセット印刷を同一の被印刷体に、精巧な模様の刷り
合わせを完全に行うことができる。According to the printing method of the present invention, the intaglio ink does not transfer onto the tint block pattern consisting of halftone dots or fine lines, and the intaglio ink transfers only to the other surface of the printing medium, so a very high printing pressure is required. It is possible to completely perform delicate printing of delicate patterns on the same substrate to be subjected to intaglio printing and offset printing which can be printed with a low printing pressure.

刷体から離れる際にこの溶剤層がただちに分離し、結果
として凹版インキが先刷りの印刷画線（未乾燥インキ）
の上に転移しないという現象によるものである。This is because when post-printing intaglio printing is performed immediately after pre-printing dry offset or wet offset printing, the post-printing intaglio ink is completely transferred to the non-image area of the pre-printing, whereas the pre-printing printing On the image line (undried ink), the hydrophilic solvent component in the intaglio ink is deposited, and a solvent layer is formed between the offset ink and the intaglio ink, and this solvent is used when the intaglio plate surface separates from the printing medium. Immediate layer separation, resulting in preprinted streak ink (undried ink)
It is due to the phenomenon that it does not transfer to the top.

いようにすることが良い。In order to make perfect printing of delicate patterns on the same substrate, intaglio printing that requires very high printing pressure and offset printing that can be printed at low printing pressure are usually offset inks. It is preferable that the amount of ink is printed in excess of the normal printing conditions so that the intaglio ink printed later is not transferred onto it.
