Type of printing

œRelief printing
A method to do the part which wants to leave ink in one of the print methods using the irregularity of the version in a convex, and to touch ink on the convex part, and to copy on paper.
The type printing is this plate type. On the letter which paper could roughen it, and was printed by pressure in the print than a fact I have characteristic such as the merge null zone where a letter becomes big being born.
The type printing goes out of fashion by a version being made of lead or the development of the offset printing in the present age.
Performed Toppan Printing is flexography mainly now.
With the flexography in substitution for printing using a version made of rubber and the photosensitive resin, I use the roller called the older brother locks roller for the part which supplies ink to a printing block.
There is little negative pressure (called the kiss touch); save it and is used for the print such as corrugated cardboard or the packing film.
In addition, the woodcut performed in school education in time for art hits this.
Seemingly the woodcuts seem to be classified in an intaglio, but after sharpening it, (recess) is white, Because a place (salient) that I did not sharpen is printed with a color of the ink, this is Toppan Printing.

œIntaglio

A method to copy the ink which leaves ink only for the recess of the version in one of the print methods using the irregularity of the version, and remained in the recess on paper.
board using the cylinder of the electronic engraved copper sheet is often used and turns to large quantities print now because a durability degree is high.
Because I can express a delicate level and a small level, it is adopted to paper money and a revenue stamp for the purpose of forged prevention.
The copper sheet sculpture using etching is a kind of the intaglio print, too, and this is also performed by a class of the art of the school education.

œPlanography

The place that wants to leave ink by giving chemical processing on the flat board hydrophobicity, After having made the place that I do not want to have hydrophilic, I soak it with water,
A method that water resists ink as for the hydrophilic part by riding ink after having moistened a hydrophilic part and leaves ink only for a hydrophobic part.
Generally, I am apt to be confused with offset printing, Because the offset printing refers to copying ink from an original version to rubber versions once; the name that is official surface printing.
The lithographs are kinds of the monotonous print, too.
Most of modern Japanese printed matter are printed by planography offset printing.
Because an image on the board does not turn over unlike intaglio relief printing of the character cloth with splashed pattern, confirmation is easy.
In addition, I am suitable for high-speed mass printings.

œMimeograph

A method to copy the ink which opens a lot of minute holes on the printing block which does not let ink go through, and passed there by pressure on paper.
‚o‚q‚h‚m‚s‚f‚n‚j‚j‚n which RISO KAGAKU CORP. sells hits this.
The silkscreen used for a reproduction picture is a kind of the mimeographs.
