SH-K100 Paper Punching Machine & Inline Flexo Printing System

SH-K100 is a standalone paper punching machine. SH-K100B combines 3-color flexo printing with inline punching. SH-K100D combines 4-color flexo printing with inline punching and includes corona treatment for double-side coated paper applications.

The SH-K100B and SH-K100D are integrated printing and punching machines. Therefore, the printing speed must be synchronized with the punching speed. Although the punching speed itself is relatively fast, the overall printing speed is still slower compared with a dedicated high-speed printing machine. The printing speed is approximately 25 meters per minute.

SH-K100, SH-K100B and SH-K100D support paper widths up to 1000 mm.

Yes. SH-K100D is specified for both single- and double-side coated paper and includes a corona surface-treatment system to support adhesion on double-side coated material. If you require higher-quality printing, we recommend using a system such as the WSGP1000, where the printing and punching processes are separated. Printing quality is directly related to the printing speed and printing method. If the cup design requires heavy gradients, fine color transitions, or more sophisticated graphic quality, the SH-K100D may not be the most suitable choice. For this type of high-quality design, we recommend using a separate printing machine such as the WSGP1700, or another machine with a similarly high printing speed and more stable printing performance. In short, the SH-K100D is suitable for standard paper cup printing, while designs requiring more advanced gradients or higher visual quality are better produced with a dedicated high-speed printing system.

The SH-K100B is designed exclusively for single-side coated paper. The printing surface must not be coated. In addition, the printing quality is limited to standard paper cup printing quality. If your cup design contains a large amount of gradients, fine color transitions, or detailed graphics, we recommend using a separate high-speed printing machine such as the WSM-1000. Printing speed has a direct influence on printing quality. High-speed printing makes it possible to use high-LPI (Lines Per Inch) ceramic anilox rollers, which can provide a finer and more uniform ink transfer surface. It also allows the use of high-resolution photopolymer printing plates suitable for finer image reproduction. In low-speed printing, however, it is difficult to properly use very high-LPI ceramic anilox rollers and high-resolution printing plates. If excessively high-LPI components are used at low printing speeds, stable ink transfer may become difficult, and the result may not be sufficiently sharp or clear. Therefore, for designs requiring fine gradients, high-resolution graphics, and superior printing quality, a dedicated high-speed printing machine is recommended. The machine supports a maximum of 3-color printing

The paper material we recommend most is 100% virgin pulp paper. Recently, as raw material costs have increased, some paper manufacturers have tried to reduce production costs by mixing fillers such as calcium carbonate (limestone powder) or using bamboo pulp. A moderate amount of calcium carbonate may not cause a serious problem. However, when the amount is excessive, it can create a large quantity of fine white dust during paper cutting and forming. This dust can accumulate inside the paper cup machine and can also accelerate wear of the cutting blades in the punching machine. When fine white paper dust enters the clearance between the female and male cutting blades, it can act like an abrasive material. Over time, this may reduce the sharpness of the cutting edge, resulting in a rough or uneven cut instead of a clean and smooth cutting surface. In severe cases, the blades may need to be re-ground or reconditioned to restore their sharpness. We also do not recommend paper containing a high proportion of bamboo pulp. Bamboo-pulp paper generally has a rougher fiber structure and surface compared with high-quality virgin pulp paper. This rough surface can also act abrasively against machine parts and cutting blades, potentially shortening their service life. If a large amount of white powder or dust is produced after the paper is cut, this may indicate that the paper contains an excessive amount of mineral filler. In such a case, we recommend checking the paper quality and considering replacement with a better-grade material. One simple way to compare paper quality is to hold the paper against a strong light. High-quality 100% pulp paper usually appears relatively uniform, smooth, and slightly ivory in color. Paper containing a high proportion of bamboo pulp may appear darker, less uniform, and visibly rougher in fiber structure. For stable machine operation, clean cutting, and longer blade life, we recommend avoiding excessively dusty paper, heavily filled paper, and paper with a very rough fiber structure.
