Contact coding type
These machines print or mark on products by contacting the product surface. They mostly use some letters made up of metal or rubber and ink media like liquid ink or a ribbon or solid ink etc. to make an impression. The letters are made offset, so while printing they give mirror image and straight print is obtained.Non contact coding type
These machine do not comes in contact in any way while printing or marking on products. Normally these machine uses beams/spray to mark. These beams may be emanating from laser, or the spray of ink as with a continuous inkjet printer, the most important factor is that the product or machine should be moving at constant speed.The moving product are sensed by a sensor and give a signal to the machine which responds immediately with the printing.
These machine also work as online machines. A few machines in this category are Inkjet printer, Laser printer, industrial Inkjet coding machine, laser marking systems.
