What is the difference between laser engraving and imprinting?
Engraving is a method of marking a promotional product by a computer laser beam. This laser beam will typically remove ("burn off") the outer coating on a product, such as a pen, and hence expose the under color of a product. For example: A pen may have a blue barrel. A laser will remove the blue coating where your logo is marked, and expose a gold or silver tube underneath. No ink is used in the process. This is the longest lasting marking type.
Imprinting is a method of applying your marking (ie your logo) to a product in color using ink. Screen and pad printing are the most common types. This allows the customer to choose the color they want on a product.
Imprinting by Pad printing: is a method of imprinting in which a recessed surface is covered with ink. When the plate is wiped clean, ink remains in the recessed area. A silicone pad then presses against the plate, pulls the ink out of the recesses and is pressed directly against the product.
Imprinting by Screen Printing: is a method in which the image is transferred to the printed surface by ink squeegeed through a stenciled screen stretched over a frame. Screens are treated with a light-sensitive emulsion, then film positives are put in contact with the screens and exposed to light. The light hardens the emulsion not covered by the film, leaving a soft area on the screen for the squeegee to force ink through. Also called silkscreening.
Full color digital printing allows for a full color imprint without extra cost per color.
