- This week, Mike will demonstrate some tips and tricks on engraving a photograph onto our 3mm TroGlass Clear cast acrylic using our Speedy 300 laser engraving machine.
He will use CorelDraw as a design program with the following techniques: contrasting the brightness, sharpening the image and converting it to a dotted black and white pattern.

Very nice explanation of an elusive subject. Way too many people putting out half baked info on laser engraving, but you my friend, are born of patience. Thanks
THANK YOU SOOOOO MUCH! This video is EXACTLY what I've been looking for. You guys are the BEST!! 👏💯😄
Thanks we appreciate the support! :)
Gracias really helpful.
Thanks Lauren!
At last have to change to halftone?
BEST INSTRUCTION TILL DATE
pankajraj parmar thanks!
Great video. Is there a correlation between the dpi you chose (for the acrylic print) and the resolution of the photo you started with? What dictates you choosing a 600 dpi vs, say, 1000dpi?
What's the reason for turning off the air assist during acrylic engraving?
Hey Trotec, thanks for the good videos.. Just want to present some kind of help for any photos to be engraved
Even if it is in very low quality
I can still retouch it and make it ready for engraving in bmp format
Keep the good work up
Thanks Karim, much appreciated!
Nice and detailed tutorial sir. Please show us the final result of engraving too as that will help a lot.
Thanks Maninder, you can see the final result in the first few seconds of the video.
Hi will a diode laser do this or does it have to be a co2?
This engraving is beautiful! I have a Glowforge and I know the settings would need to be different. Any advice you can give me on how to get the correct settings with mine to get this same result? Or would I just convert the image exactly the same and use the same settings that I'd normally use on my Glowforge? Also, I use Inkscape to convert my photo the way you did? Or would I need to use another software? Thanks!
So I have a glowforge as well. I only successfully was able to engrave to where the picture was very clear once. I don’t know what I did. The issue I’m running across is actually getting it to convert to whatever first not necessarily the settings on glowforge. Just select the acrylic option that setting seems fine but it’s the converting the picture properly is the issue for me; I’m working on it today so if i figure it out I will let you know.
Hello, can I use P7 M30 Engraving Machine to engrave acrylic?
I just followed Mike's directions, and OMG I just amazed how well this just turned out, thank you so much for sharing, Is there an updated website for MIke? this link which is posted is broken :(
Thanks!! The engrave.ca is broken?
Trotec Canada, yes sorry should of stated that.
Can i do same steps for engrave on acrylic if i have CO2 40w ?
Why do you run it at 600 DPI when the image is 300 DPI? Telling it to increase the DPI is not going to increase your detail - it will instead make your dots overlap each other more than they are in the original and reduce the amount of white space.
Another question I have always wondered about is when you select "automatic", what does the software use to determine an optimal PPI? Is it a percentage of other factors? Is it based on the level of light and dark detail? I assume Trotec is defining PPI as PULSE per inch rather than PIXELS per inch?
Regarding running the laser at 600 DPI when the image is 300 DPI, the reason for this is to improve the quality of the engraving. When the laser is set to 600 DPI, it is able to produce more intricate details by firing the laser at smaller intervals, resulting in a higher resolution image. While it is true that simply increasing the DPI will not add additional detail to an image, it can improve the clarity and sharpness of the details that are already present.
When selecting the "automatic" option in our software, the PPI is determined based on a variety of factors including the material being engraved, the speed of the laser, and the complexity of the design. Our software uses an algorithm to analyze these factors and determine the optimal PPI for each project. This allows for a more efficient and effective engraving process.
And yes, Trotec defines PPI as pulses per inch, rather than pixels per inch. PPI refers to the number of laser pulses that are fired per inch of travel by the laser head. This measurement is used to determine the resolution of the engraving and can be adjusted to achieve the desired level of detail for each project.
I hope this information helps! Please let us know if you have any additional questions or concerns.
@@TrotecLaserCanada This is interesting info - thank you. So, if the image has no detail (white) for a given pixel, does the PPI number still ignore the white pixels regardless of the PPI? Or will an increase in PPI at some point produce overlapping pixels (and produce less detail, darker) if the setting is increased more than the number of distinct individual dots the laser is capable of producing per inch? Does the automatic setting avoid overlapping dots or will that still happen?
I’m new to this laser engraving and I would like if you can advise me here. You used 45% with 100 speed with your 80w laser. If I’m using a 20w = to about 5.5-6w laser, what % and speed I would have to use.
where to buy the machines?
Hello
What about the optimized photo mode for engraving in job control?
Does It work?
Hi Miguel, yes that would work but we still advise to touch up the photo in your design program. Every photo will be different.
Do you see machine in india?
Yes. If you would like pricing please visit our website www.troteclaser.com and go to the CONTACT page. Contact your local Trotec rep and they will provide pricing.
What are the settings
The website link to the tutorials isnt working... has it been decommissioned?
I would like to do this on a scooter windshield would you be able to do that please comment back thank you for this video
Is your scooter windshield curved? That makes a big difference on the ability of a laser to engrave.
You may want to consider using sand blasting an image.
@@DJ-73 It does have a little curve to wait
@@martinneps9387 I know an AP laser can do it. Some laser machines will only engrave on a flat surface and then there is the fact that the bed area doesn't adjust down. Look at AP laser on RUclips. Its an awesome laser
I had a questions can you use regmarks and engraving to engrave Certain parts of your image??
No unfortunately the reg marks are only for cutting - for now at least.
I am using black akralic material what should I change
Invert the colours so it looks like a colour negative. The rest is the same.
What color acrylic was this done on? Was the back painted black?
Hi Jennifer, this was on clear acrylic, we just placed it on a black background.
What version of corel is used here?
May be X6 or X8
UMM... THE RESULT?
Thanks but when you don't see the actual product result it remains abstract and theoretical.
sir please more tutorials for clear acrylic and wood engraving please
Thanks we'll try our best! :)
@@TrotecLaserCanada Wich laser module is used? CO2?
@@mikekiske Yes CO2
@@TrotecLaserCanada Thank you very much.
Im planning to buy a K40 unit do you think I can get the same result?
So if these were done by a professional photographer, did you have copyright permission to use his photo?
If you plan on selling these images then yes you have to have permission from the photographer.
I 2nd Darius' question - about the photographer's copyright. They make most of their money on the prints and usually not as much on the sittings. Clearly your client originally brought in a photographer's proof (low res). Printing from that would violate the photog's copyright. That's why they give clients low res files. Copying from the original print is also a violation of the photog's copyright. The client was sold that single print. It's not a "negative" the client owns to make as many duplicates as possible - unless the photographer provided a writtten release to treat it as such...
Hi Cindy, are you talking about in general or in this particular video? In general, engravers who do photographs usually do them for weddings and special events. In which case we always suggest to double check with the photographer about re-making the photo onto a piece of wood or acrylic.
Lol give me a break
uh-gayn
If this was done on a 300, what settings would you recommend for the 100 series
Hi Darrell, we made a special video to find out your own laser settings: ruclips.net/video/3-NW9uwwrFI/видео.html
