SUMIMARK® III Marking System

SumiMark® III is a high performance, high speed thermal transfer marking system designed to print on continuous spools of a wide variety of SumiMark® tubing materials and sizes (Tubing diameters from 1/16" to 2"). The SumiMark® III produces a dry, permanent mark that can be handled as soon as it is printed. After recovery, our printing meets the demanding mark permanence requirements of SAEAS81531 for both abrasion and solvent resistance.

The 300 dpi print head produces crisp, high quality text, barcodes and graphic images. The capability to print on continuous spools of a large range of tubing materials such as polyolefin, fluoropolymer, and dual wall adhesive lined, allows the end user the ability to design a marker tag, which can be used in the most demanding and severe environments.

Creating custom markers or retrieving wire lists from a database is a simple step by step menu-driven process.

COMPANY PROFILE

Origins of Sumitomo

Masatomo Sumitomo The Sumitomo business was started in Kyoto, the historic capital city of Japan, nearly 400 years ago by Masatomo Sumitomo (1585-1652) and Riemon Soga (1572-1636). Masatomo is regarded as the spiritual founder of the Sumitomo Group. Following an early career in the Buddhist priesthood, he established a shop in Kyoto that sold medicines and books. In accordance with custom of the time, Masatomo produced written teachings for his household and disciples. One volume of these, which provided advice on conduct of commercial activity, has been come to be known as the "Founder's Precepts" and is the basis of the code of conduct for the Sumitomo Group of companies.

Riemon, who was a disciple and brother-in-law of Masatomo, was the technological pioneer who set the Sumitomo business on the path to commercial success. Having studied copper refining, Riemon established the Izumiya copper business in Kyoto in 1590. Until the late 16th century, Japanese copper merchants did not possess the technology to extract the silver contained in copper ore, which compelled them to export the ore with silver intact. By learning and perfecting western smelting methods, Riemon engineered a revolution in Japanese copper refining. The Sumitomo business was continued by Riemon's eldest son, Tomomochi (1607-1662), who entered the Sumitomo family through his marriage to Masatomo's daughter. Tomomochi moved the copper smelting business to Osaka, Japan's commercial capital at the time.

Copper Refining Process

One of the epoch-making events in the early days of the Sumitomo family was the 1690 opening of the Besshi Copper Mine on the island of Shikoku, across the Seto Inland Sea from Osaka. The Besshi Copper Mine was extremely productive and profitable right up to the early 20th century. Consequently, it played a pivotal role in the birth of many core companies of the Sumitomo Group today.

In 1891, Sumitomo formulated its Business Principles, which are based upon the "Founder's Precepts" by Masatomo. Article 1 explains the necessity of acting in good faith in order to maintain the other party's trust. Article 2 urges that social trends should be studied in order to meet social changes with active responses. Article 3 advises against being attracted to easy profits or hastily drawing to the promise of profits before fully investigating the commercial viability of ventures.

The emblem of Riemon Soga's original business, Izumiya (izumi "spring" and ya "shop"), and many Sumitomo companies today is an igeta, a frame placed around a well in premodern Japan. The igeta symbolizes sparkling water gushing constantly from a fountainhead, which forms a mighty river before flowing into a vast ocean.
