摘要： PROBLEM TO BE SOLVED: To obtain a clear printing image by suppressing change of a pattern line width due to outer diameter difference of materials to be printed with continuously changing outer diameters like a truncated conical container by using an offset blanket having surface hardness and roughness of surface rubber of specific ranges. SOLUTION: The offset blanket 1 for printing a curved surface comprises a surface rubber 2 and pressure-sensitive adhesive 22. A truncated conical container applied by this invention has 20mm or less of a difference between a maximum outer diameter part and minimum outer diameter part of a region where the blanket is brought into contact with the container. A line width A of a pattern printed on a printing central part, a line width B1 of a pattern printed on a maximum outer periphery and a line width B2 of a pattern printed on a minimum outer periphery are measured, its ratio B1 /A and B2 /A are obtained, and they are used as an index of line width change. When surface hardness (JIS A) of the rubber is set to a range of 30 to 65 and surface roughness (Rz) is set to a range of 3 to 7μm, a value of the index of line width change can be fallen within a range of 1.0 to 1.2.

摘要： PROBLEM TO BE SOLVED: To provide a blanket for printing which reduces the accumulation of ink on a surface printed layer and prevents print flaw such as the edge blur of a printed pattern by making the part which does not come into contact with an object to be printed thinner in thickness than the part which comes into contact with the object to be printed. SOLUTION: A blanket 30 for printing is formed by making the part 6 which does not come into contact with an object to be printed thinner in thickness than that of the part 5 which comes into contact with the object to be printed. Consequently, it is possible to divert ink emulsified in wetting water in the part 5 which comes into contact with the object to be printed at the time of printing to the part of smaller thickness. Specifically, the blanket 30 for printing has the part 6 which does not come into contact with the object to be printed, formed to have a thickness t1 smaller than the thickness t2 of the part 5 which comes into contact with the object. In order to reduce the thickness t1 of the part 6 which does not come into contact with the object, a means ca be used which reduces the thickness of the end part of the blanket 30 by adjusting the width of each of the layers of the blanket 30 at the time of its manufacture.
