The laser engraving technique has taken the front row in delivering personalized engraved items as per requirement. As the laser engraving process involves permanently carving the desired text or image on a material’s surface with precise focusing of a high-powered laser beam, it requires proper setup.

Any desired design or photo can be laser engraved onto a material using graphic design software compatible with the laser engraver. I denne forbindelse, Lightburn is considered a layout, redigering, and control software that works seamlessly with a diverse range of laser engravers.

ComMarker offers the most premium quality laser engravers which allow easy connectivity with Lightburn resulting in high-quality engraving results. derimot, the outcome of the project also heavily relies on the speed, makt, and mode set for the laser engraver.

These determine engraving depth, detail, teksturer, visual effects, and reduction of material damage. To elaborate on how different speeds and modes affect the photo engraving on a material, we have conducted an experiment where a ComMarker B4 fiber laser markeringsmaskin is set up.

There is Lightburn software installed that gauges the working of the laser engraver. The purpose of the experiment is to explore how different modes of the Lightburn programvare affect the engraving of a photo on a material. To gain more details, refer to our detailed article below.

The Experiment Setup

Within the arrangement, the laser engraver used is the ComMarker B4, which is one of the leading fiber laser engravers offered by the firm. The materials compatible with the lasergraver are aluminum, rustfritt stål, gull, sølv, titan, some acrylics, cowhide leather, painted wood, and plastics.

The laser engraver is placed on a flat desk and plugged into a power source in this setup. The parameters of the ComMarker B4 in place for the experiment are the speed set at 1000mm/sec, and the max power of 30% applied. The Line Interval is set at 0.06 with the Dither sample at 0.020.

The software used for the experiment is Lightburn to create and edit vector graphics from within the software directly. Various formats like AI, DXF, PDF, SVG, and image files can be imported into the software. Import any desired picture from the files of your desktop on the software.

The next step is to adjust the size of the picture according to the engraving that needs to be done. In the set-up, the image is set with a height of 32.25 mm and a width of 40.963mm. Etter det, the mode needs to be chosen which will determine the texture, details, and the overall loom of the picture created on the material.

Modes Explored

Now let’s talk about the modes that can be used for the picture marking in the ComMarker B4 fiber lasergraver and how they affect the overall result of the image produced. Here are some we would like to mention below.

1. Threshold Mode

The images with clear contrast, for simple black and white lines this mode is used. Two-colored images, like the one used in the experiment, logoer, and texts can be made with this mode of the Lightburn.

Apart from this to create outlines of certain images, this mode can also be applied. At the set power level, pixels darker than the threshold mode set are engraved. Choose the Threshold mode from the mode option within the software.

The engraving depth is the same in this mode, and it cannot be varied. With the experiment, a picture is created with only the outline and black and white lines visible, but the details are not clear. This mode is not ideal for grayscale images.

2. Ordered Mode

Neste, we have the ordered mode chosen for the experiment, mostly used for the grayscale effect. To engrave cartoons, unshaded images, and a structured picture, ordered dithering mode is a potent mode. A predefined grid or pattern like the Bayer matrix, or Stucki matrix is used in this mode.

If the partitioning is visible in the image provided, then the shading done on the image comes out in good quality. In the experiment, the image created with this effect is balanced and every detail is visible.

3. Atkinson Mode

Another mode that can be used for picture marking through Lightburn is Atkinson Mode. Images with subtle details like illustrations or photographs can be created by selecting this mode. This is a mid-way option and a standard approach for solid colors and smoothly shaded images. It preserves more details of the photo and reduces noise. derimot, this works slower than threshold mode and takes more time to create all the details of the image precisely.

Within this mode, in the B4 jpt fiber laser engraver different error diffusion levels should be considered. This is to adjust the balance between the detail and processing speed. In the experiment conducted, the image created with this mode is precise, with the lines and details visible and in balance with the lighter parts of the image.

4. Theard Mode (Floyd Steinberg Diffusion Dithering)

This is a common dithering algorithm used in grayscale engraving from a laser engraver. For photorealistic image creation, this is ideal. This engraving method uses a pattern of engraved and non-engraved pixels to create the illusion of continuous tones in grayscale.

Select the “Floyd-Steinberg” pattern from the Ordered Dithering option in the Lightburn software to enable this specific dithering method. In this experiment, it is not considered the best choice for picture marking in this experiment, as it creates a light image with the darker details not entirely visible.

5. Stucki Mode

For high-quality dithering, Stucki mode is mostly chosen to create photo images during laser engraving. To compare pixel brightness against other thresholds, use a predefined grid or pattern for better results, like Stucki 16×16, Stucki 4×4.

Compared to other methods, this mode provides precise control over grayscale transitions within the photo. This mode is also comparatively faster than others, creating better results. You have to adjust the dithering level to control the size of the dithering pattern and processing speed in Stucki mode.

A well-balanced picture is created in this experiment with this mode and all the depths, linjer, and minor details are easily visible. This makes it a viable option for grayscale image engraving on different materials, creating some of the top selling laser engraved products.

6. Jarvis Mode

A superior mode among all these used through the Lightburn software for precise image creation is the Jarvis mode. It offers excellent details and the transitioning between different shades provided through this mode is seamless, making it a popular option.

It can be selected from the image mode in the software and applied to the desired material. With reduced noise in the picture and relatively faster processing speed than other dithering modes, Jarvis is considered one of the most prominent modes. It is a valuable tool providing high visual quality for smooth-shaded photos.

The most outstanding image is created as a result of this mode in the experiment conducted, which is the closest resemblance to the image provided for engraving. The colors are balanced with all lines visible.

7. Newsprint Mode

The halftone effect of printed newspapers can be created by choosing the newsprint mode through Lightburn. To achieve this effect, it uses a pattern of dots of varied sizes to represent the image’s various grayscale tones.

When you are trying to achieve a vintage newspaper printing style on a material, then the dot pattern created by this mode is ideal. Simple image creation can be done through this mode. The outcome of using this mode in the experiment performed is accurate and visually of top-notch quality. This mode is highly effective as it works at a high engraving speed.

8. Halftone Mode

The next mode we want to mention used in the experiment is the halftone mode, which provides various engraving depths depending on the image brightness. When the image that needs to be engraved is of moderate to high detail quality, then halftone mode comes in use.

This is a step ahead of the newspaper mode, where the noise can be visible in the picture, making it appear with grains. Instead of fixed-size dots, Halftone Mode utilizes cells of varying sizes to represent different shades. In the experiment, the use of Halftone mode creates better brightness for the darker areas by reducing the contrast levels.

9. Sketch Mode

Sometimes there is a requirement to engrave line drawings and handwriting on a specific material. The sketch mode comes into play in this retard, this mode within Lightburn is specifically used for handwriting. It detects the edges of the image and only prints that.

In the experiment, this creates a poor-quality image, as only edges and lines are printed on the material. The image is not visible and with no shading, the image is not complete. This mode has limitations in its use and is only useful for certain types of images.

10. Grayscale Mode

Endelig, we have the grayscale mode, which allows 3D engraving easily, but with specific laser types like CO2. Using LightBurn’s Grayscale Mode,  3D engraving can be achieved.

The engraving depth is adjusted according to the image’s brightness, resulting in realistic grayscale effects. In comparison to other modes, such as dithering, it provides the most degree of detail and makes the cleanest transitions.

Photos, portretter, artwork with delicate coloring, and elaborate patterns all perform well in this engraving technique. A fine image with all depth and details visible is created with this mode in the experiment. It is highly compatible with fiber laser machines like ComMarker B4.

Results and Analysis,

Alt i alt, de ComMarker B4 MOPA Fiber Laser engraver is a perfect tool for creating grayscale and colored images according to the provided picture. With our findings in the experiment, Jarvis mode create the most detailed and clear images of the material under similar settings.

The rest of the modes require adjustments to create an ideal result. The final product and image engraved as a result of using this mode are marketable and of high quality. This will directly result in high sales for the firm as it is precise to create custom designs for the customers.

For a more detailed demonstration of the photo engraving process using LightBurn with the ComMarker B4 laser engraver, you can view our video here: https://youtu.be/UAq0SaKYz4I?feature=shared

Due to still being a modern technique, it requires a particular method to be followed for excellent results. For the desired image, use a photo editor to edit it according to your choice and convert it into grayscale. This photo has different gradients, which the laser beam scans later on.

The high-beam laser removes the top layer of the material used where the picture is pre-determined to be. Colored engravings with fine details can also be made through photo engraving now. Due to being high in demand, different industries such as home decor, smykker, interior design, and product production make use of it.

If we talk about which materials are compatible with lasergraver in terms of photo engraving are generally wood, akryl, glass, and metals. This is seen as a fast-evolving industry, with the photo engraving market size reaching over 2 Billion in 2023.

In this aspect, manufacturers and startup founders look for reliable lasergraveringsmaskin that offer bulk production of products. ComMarker is a leading provider of laser engraving machines in this aspect, with its machines showing an accuracy of 0.01mm.

The materials mentioned for laser engraving have properties that show affinity with the engraver. They create high-definition images and provide durability. Our article focuses on how effective photo laser engraving can be made possible with a range of materials and tips to care for the product later on.

Choosing the Right Photo for Engraving

The characteristics of the material on which the photo is to be engraved need to be considered before starting work on it. It helps us determine which photo will go perfectly with a certain material. In photo selection, choose a photo with a high resolution for crisp results.

Not one power of the laser engraving machine can be used on various materials. For each one of them, the power, hastighet, Frekvens, and line interval need to be adjusted accordingly for each of them. Another factor to be considered is that while choosing the photo, select one that has a plain or simple background with no distractions in the back.

Different materials showcase different strengths during laser engraving. For metaller, photos that have patterns and details should be considered. The next material is acrylics and most people opt for high-contrast photos with these. Acrylics show transparency, so a high-contrast image or photos with bold graphics will mesh well with the background. derimot, sculpting acrylic requires a certain amount of professional technology, so to a certain extent, acrylic engraving is a test for non-professionals. ComMarker B4 MOPA fiberlaser Engraver works ideally well for all these materials and should be considered for your next project.

Editing Tips to Make Photos Suitable for Engraving

Adjusting the photos so they adapt well with the material and final results might also require some editing on the editing apps. For a smooth experience while editing photos, here are a few tips you can follow.

• First and foremost, the Adobe editing app and other tools need to be installed. These apps not only offer different formats after editing that will be compatible with the laser engraver’s software but also are easier to use.
• With a proper editing tool, you can sharpen the photo to be engraved. På denne måten, the details of the photo are not blurred and remain crisp.
• Another great tip is to increase the contrast of the photo. It creates a great balance between the image’s engraved area and its non-engraved background.
• There are also features in the editing tools where you can remove unnecessary things from the photo of your choice. If you want an object or extra details removed from the background, use the tool, which then helps the laser engraver to create detailed images.
• Fix overexposed areas of the image by adjusting the brightness level from the editing app. This creates a more uniform appearance for the photo.
• To create personalized effects on the images, name initials or dates can be edited on the photo. This will create a personal style and feel of the image.

Laser Engraving on Wood

To create photo artwork, hjemmeinnredning, and other items, wood is generally used. derimot, this can be challenging due to wood being sensitive to the high beam of laser and the risk of burning. The first and foremost step is to find the right type of wood.

Maple, poplar, and birch are popular choices in wood for getting photos engraved as these are highly durable and have smooth surfaces. Fine-grit sandpaper can be used to remove any excess on the surface, which can create uneven engraving designs.

Due to compatibility with wood, ComMarker’s QI Diode lasergraver can be used with an engraving accuracy of 0.05mm.Before starting your work, it’s beneficial to conduct a grid test, as this can help you save time by finding the optimal parameters for your task. Start with a low power setting on the laser and then gradually increase the power as needed. Select a suitable mode as it works well on wood. Når graveringen er fullført, apply a clear sealant on the wood and add paint to customize the engraving further.

Laser Engraving on Acrylic

Keychains, dalbaner, and other products can get a frosted effect using laser engraving. To create high-quality images, higher resolution is opted for in photos for better engravings. Clarity and optical quality should be considered while choosing the acrylic material for the engraving.

One more factor that should be considered while choosing acrylics is the thickness of the materials. For engraving photos of decorative pieces, thin sheets of acrylic (2-3mm) should be chosen. While thicker sheets (5-8mm) are suitable for keychains and other items of regular use.

Then choose the photo with a high contrast by editing it on the editor app. Select the right laser engraver for this, which can be ComMarker’s B4 JPT LP laser engraving machine. This is compatible with acrylics and creates deep markings with 110x110mm field lens. To avoid cracking of acrylic, conduct a grid test before engraving to help select the optimal parameters.

Small line interval can be used to create fine details. With a microfiber cloth, you can polish the engraved area after engraving. This also avoids any scratches.

Laser Engraving on Metal

Being highly reflective, metals are the most challenging to engrave photos on but provide the most longevity. Stainless steel., anodized aluminum, and titanium are the most popular choices for laser engraving photos due to their polished surfaces and weather resistance. Clear carvings can be created on these.

The thickness of the metal sheet is an important factor to consider when choosing materials for laser engraving. Thicker sheets, typically 2-3mm, are better suited for intricate engraving of detailed designs, as they are less prone to warping from the heat generated during the engraving process. På den andre siden, thinner sheets, around 0.5-1mm, are suitable for engraving smaller images or for post-engraving shaping using laser cutting to create unique designs. Choose the best suitable resolution of photos and for this purpose, a minimum of 600 dpi should be chosen. This is for creating more precise and crisp results.

Edit the photos accordingly, and use a laser engraver such as ComMarker B4 JPT fiberlaser at low setting. For titanium use higher power and for stainless steel use low power to create a better-quality image. Etter gravering, use a soft cloth to lightly polish the engraved area. Clear coat sealant should be applied on this to prevent the metal from getting oxidized with time.

Laser Engraving on Glass

Drinkware and tableware are made by engraving on glass easily, and it is another material that is popular for photo engraving. Glass has different properties such as thermal fracture and the ability to burn. This makes it a challenging material to engrave on.

With the help of this, customized presents and artistic decorations can be created easily. For dette formålet, the ComMarker UV Laser Engraver is the proper tool as it is engraved on different glass finishes without any hindrance. For different finishes different results are created at the end if we look at glass types people prefer, Borosilicate glass, tempered and frosted glass for photo engraving.

As with other materials, high-resolution photos of at least 300 dpi should be chosen. Photo inversion during editing can be done for a white-on-black effect, which is unique. Post engraving, apply a sealant on the engraved area for long-lasting results.

Post-Engraving Tips

To keep the results of photo engraving for longer periods, you need to maintain it after the engraving process. Cleaning the area along with polishing and sealing it is necessary. To get more tips regarding keeping the photo engraving looking fresh for a long, follow the tips below.

• Laser engraving can leave debris on the material, which can result in not so smooth a finish. To remove this and not hinder the outcome, you can make use of a gentle brush to clean that area.
• Compressed air can is also used for sensitive materials to remove any debris.
• Another cleaning tip is to use a moist cloth to wipe any residue from the edges of the area engraved to not ruin the whole image.
• Etter rengjøring, use a microfiber cloth to polish the area before applying a sealant. Merk: In theory, items that have been laser engraved do not require a sealant to last a long time, but using a sealant can better prevent oxidation or discoloration of your work.
• If we look at sealing the engraved area, then a sealant like varnish should be applied to the respective area. The material characteristics and compatibility with the sealant should be considered for ideal results. This helps the results not oxidize or change color by interacting with the sealant.
• Another great tip is the use of UV protectant spray, which reduces the effect of sunlight on the engraved area. This helps the image not fade out or look worn after some time.

Konklusjon

The photo engraving industry has seen a tremendous increase in recent years due to social media networks becoming a common means of staying connected. People prefer giving each other personalized gifts, which has given a chance to laser engraving industries to utilize the full potential of this.

derimot, choosing different materials such as metals, akryl, tre, and glass to laser engrave photos with fine details is a meticulous process. We hope this article helped you understand how to laser engrave photos on different materials effectively.
