Etched signs 

It is considered a special type of sign that is often very popular for use in decorating places, rooms, and buildings.

Etching and UV printing are two techniques used to create signs or printed media, with the following differences:

  • It is the use of acid to etch patterns onto materials such as metal, glass or plastic.
  • Gives a deep feeling to the material, can be touched with hands.
  • The resulting patterns are usually sharp and suitable for work that requires high resolution.
  • Environmentally durable, suitable for signs that require permanence.
  • Color can be applied to the etched grooves to enhance their beauty.
  • The production process takes a long time and is more expensive than UV printing.
  • Suitable for detailed and high quality work.

    • UV ( Ultraviolet Light) printed signs

    A type of digital printing process that uses special inks that dry and harden quickly when exposed to UV light.

  • It is the use of acid to etch patterns onto materials such as metal, glass or plastic.
  • Gives a deep feeling to the material, can be touched with hands.
  • The resulting pattern is usually sharp and clear, suitable for work that requires high resolution.
  • Environmentally durable, suitable for signs that require permanence.
  • Color can be applied to the etched grooves to enhance their beauty.
  • The production process takes a long time and is more expensive than UV printing.
  • Suitable for detailed and high quality work such as logo signs, table nameplates, engraved award plaques.

    • Therefore, acid-etched signs have a pattern embedded in the material, while UV printed signs have brightly colored patterns on the surface of the material.
