Glossary Of Terms

The SGIA Glossary of Terms serves as an excellent industry terminology resource. It is the language by which we all communicate, without it universal understanding would be impossible. Language and our ideas about how it is interpreted change rapidly. SGIA is aware of this and continues its effort to keep our constituents well informed about changes to the increasingly complex industry terminology. The definitions are for general reference only. Usage may vary between companies, individuals, or national and country customs. The information presented is as accurate as the authors and editors can ascertain and SGIA assumes no responsibility for the use of information presented herein.

  • Inks and Matched Component Systems

    Matched Components

    Solvent and UV curable inks will generally have about the same life span for a vehicle or fleet application, when you use a matched over laminate protection system. The company 3M does make inks for solvent, latex and UV curable inkjet printers that are known as MCS, or Matched Component System inks. When products are manufactured using 3M media, inks and over laminates, they are then eligible to be covered under the 3M™ MCS™ Warranty for up to 5 years of coverage. You can look up the specifics of the program at the 3M graphics site. And yes, there are clients that specify jobs that must be covered by this program, so you must have all of the necessary ingredients to be able to bid on these projects.
