ダースプレー法等が知られている。(Prior art) Conventionally, this type of set-off prevention device includes a powder spray method in which powder (fine powder particles) is attached to the paper surface using an air flow, and a powder spray method in which the powder is charged by corona discharge from an electrostatic powder spray device. An electrostatic powder spray method is known, in which the powder is applied to the paper surface.

一に付着しない。(Problems to be Solved by the Invention) In the powder spray method, the powder is attached to the paper surface by air flow, so the powder scatters to surrounding areas other than the printed matter and contaminates parts of the printing machine. In addition, in the same powder spray method, if the powder is not sufficiently dry, it will drip from the spray nozzle onto the paper and will not adhere uniformly to the paper.

着量が限度以上になると３紙面等に脱落するという問題
があった。In addition, in the electrostatic powder spray method, the powder is charged by corona discharge, but since the powder is fine powder particles and the amount of charge is small, the Coulomb force for coating one paper surface is small, and it is not possible to reliably adhere to nine paper surfaces. 2) It separates from the paper surface and scatters around 1. Since this powder is electrically charged, it tends to adhere to parts of a printing machine made of metal, and if the amount of adhesion exceeds a limit, it will fall off onto the paper surface.

A solution obtained by adding 5 wt % of powder particles whose main component is polymethyl methacrylate to water is sent to a dry fog nozzle (two-fluid nozzle) (3), and is made into an aerosol by pressurized air from a near compressor (6). is supplied from the mist chamber (2) to the printing paper (1) as a mist with a liquid particle size of about 30 μm,
After adhering to the same printing paper (1) to a state of about 0.067 mg/n, it is dried by the heater part (8), and the printing paper (
1) A powder fine particle layer of about 0.007 mg/rd is formed. Printing paper (1) coated with 44 of these fine powder particles was stacked on a printed surface of 1 ink film of 2 mtm using a sheet-fed printing machine,
When we tested the set-off property by giving the sheet a misalignment of It has been reduced to about 1/100 compared to the conventional one.

の飛散が減少して、印刷紙（１）に効率よく付着する。Next, the above action will be explained in more detail. The aerosol obtained by the dry fog nozzle (two-fluid nozzle) (3) consists of fine powder particles and droplets covering the fine powder particles, and the diameter of the aerosol is larger than the diameter of the fine powder particles. . Along with this, the mass of the aerosol (liquid particles) also increases, the scattering of one particle decreases, and the aerosol (liquid particles) is efficiently attached to the printing paper (1).

Of this attached aerosol, the liquid evaporates and disappears due to the heating of the heater section (8), so only the fine powder particles remain on the printing paper (
1) remains and is fixed.

Further, the fine powder particles are subjected to surface treatment as necessary in order to improve their dispersibility in liquid. Note that if the particle size is too large, printing quality will deteriorate and fine powder particles will not adhere properly.
