Laser Engraving A Photograph
Fiber laser technology has evolved significantly in the past few years, with its potential applications expanding beyond purely practical uses in manufacturing and research. This includes aesthetic and artistic deployments which allow for new means of expression to be achieved.
Laser engraving falls into this category, specifically because it can be harnessed to recreate photographs using different materials than are traditionally associated with pictographic printing.
Here is a look at how laser engraving a photograph works and what benefits this approach offers compared with the alternatives.
Laser engraving a photograph is a process which operates in the same way as any other kind of laser engraving. A fiber laser is applied to the surface of the material on which the design is to be etched, with the high powered beam removing a portion of the surface matter to create a distinctive mark.
This is effectively identical to the kinds of classic engraving techniques used by human artisans, although through the use of computer-guided fiber laser systems it is possible to create far more intricate designs with the utmost accuracy and precision. In many cases this means that laser engraving is used to apply text, logos and other graphics to objects.
When it comes to engraving a photograph, there is a little more going on behind the scenes, since of course it is necessary to translate the pixels of the original digital image into something that can be interpreted by the engraving machine. This is relevant because it is not possible to replicate colour elements of a photo through engraving. There are also limitations in terms of DPI, although this is relevant in any printing context.
The material options
Fiber laser engraving is a very flexible process in that it can accommodate different types of materials and also produce different end results depending on the materials chosen.
You can engrave photographs onto metal, wood, plastic and even ceramic surfaces through the process. The extent of the precision and control on offer is evidenced by the fact that fiber lasers can even be used to restore artwork, as well as create it.
The use cases
There are ample instances in which laser engraving a photograph makes sense. For example, you might want to commemorate a special occasion or treat a loved one to a gift that they can treasure that is a little out of the ordinary. Turning a photo into an engraving that will act as a permanent token of your appreciation for them could be just the sort of solution that will stand the test of time.
This is also something that businesses can use for the purposes of brand-building, corporate gifting and even office interior decoration. There are literally trillions of photographs printed out on paper, which can fade over time. If you engrave an image into a more durable material, it will not only be eye-catching but also manage to remain intact for longer.
