Common Materials for Photo Laser Engraving

The key difference between photo laser engraving and traditional photo printing lies in the materials used. Traditional methods involve printing colored inks onto paper. In contrast, photo engraving lets you etch images into a diverse array of materials – whether it’s a family portrait on a wooden plaque, a cherished memory on a metal keychain, or a beloved pet's image on a stone coaster.

Let’s take a look at some common materials, best suited for photo laser engraving:

Photo Engraving on Wood

Wood, a solid, natural material, is known for its durability and unique aesthetic appeal. It’s ideal for picture engraving. The distinct advantage of wood is its availability in a variety of hues and patterns. Each type of wood brings a different texture to the engraving; there’s a range of shades from light to dark brown.

Laser engraving wood requires careful consideration for power settings. For instance, softwoods burn quicker and thus need lower power settings for a successful engrave. In contrast, hardwoods, known for their smoothness, demand higher power for clear and detailed engravings.

Both diode and CO2 lasers work well for wood, but due to the material’s susceptibility to laser burns, we recommend using Air Assist. You may also apply masking to protect the wood surface from burns.

Metals like stainless steel, brass, and copper are popular choices for photo engraving. The engraving on these metals typically appears as contrasting shades, ranging from subtle grays to deep blacks. Notably, color laser engraving is possible on some metals (a result of oxidation during the engraving process). 

For metal laser engraving, powerful fiber lasers are common in industries. Diode or infrared lasers can also be employed for photo engraving on metals. However, CO2 lasers are generally not suitable for bare metals as their wavelength gets reflected. They can be used on coated metals.

When engraved, glass showcases a mix of white and transparent shades, creating a stunning visual effect. This makes glass an excellent medium for preserving cherished photos elegantly and timelessly.

Not all laser machines are suitable for glass engraving. CO2 lasers are the best choices for this material. However, for optimal results in glass engraving, a high-quality image is essential. You need to properly adjust the brightness and resolution so that the final image has all the critical details.

Suitable Products for Glass Photo Engraving

Stone engraving was once a challenging task with manual tools; now it’s much simpler with laser engravers. Think of creating lasting memorials, decorative pieces, or unique gifts with stones. Marble, slate, and granite are top choices for stone photo engraving.

Given the hardness of stone, powerful lasers are typically required for effective engraving. CO2 lasers are the preferred choices for their efficiency and precision. Diode lasers can also be used, although they might be less effective and may require multiple passes.

For darker stones, like slate or black marble, make sure to invert the image so that the photo appears with the correct contrast and visibility.

Photo Engraving on Scratch Paper

Scratch paper, known for its unique colorful appearance, is another exciting medium for photo engraving. The paper normally has a black or dark surface coating over a brightly colored layer underneath. When engraved, the top layer is scratched off, revealing the vibrant hues beneath.

Since scratch paper is more delicate than materials like wood or metal, a lower power setting is sufficient to achieve the desired engraving effect without damaging the paper. You may use diode or CO2 lasers to engrave it.

How to Laser Engrave a Photo?

Laser engraving photos is slightly different than traditional photo printing. It involves more than just transferring an image; it requires careful preparation and specific settings adjustments.

Here’s a step-by-step guide to ensure successful photo laser engraving:

Step 1: Prepare the Photo for Laser Engraving

Typically, realistic photos are in color formats like PNG or JPG, which are raster formats. However, for laser engraving, a bitmap image (BMP) is needed.

A bitmap image is a pixel-based image format, where each dot (pixel) corresponds to a specific point on the material being engraved. It is more likely a black-and-white image with some grey shades. Darker regions correspond to in-depth engraving while lighter/white indicate less or no engraving.

You can either convert your existing bitmap with online software like Imag R or use laser control software, such as XCS. There we have multiple bitmap modes and settings to make the photo ready for engraving.

Step 2: Laser Engraving Photo Settings

Different laser engravers have varying settings, but there are common features across most machines. Using the xTool F1 as an example, here are the key parameters to set before engraving:

Laser Type: Choose between a diode and an IR laser (for metals), depending on the material you are working with.

Dot Duration: This refers to the time the laser spends at each point, measured in microseconds. It affects the overall processing time and the darkness of the engraving.

Power: This ranges from 1 to 100%, affecting the depth and darkness of the engraving. Higher power results in deeper engravings.

DPI: This indicates the number of image pixels per inch, ranging from 1 to 1270. The higher the DPI, the finer engraving results you will get.

Pass: More passes mean deeper engraving marks.

Bitmap Mode: The xTool F1 offers seven image modes. Jarvis mode is generally recommended for infrared light and grayscale mode for blue light.

For F1, we also have pre-defined material settings, do check that before engraving and choose the appropriate material from the list.

Step 3: The Engraving Process

Once you have prepared your photo and configured the laser engraving settings, begin the engraving process. The time it takes to complete the engraving will depend on the material, your power settings, and design complexity.
