Hi all, I have a few images that I want to engrave and these images are already digitized. What mode i.e. Jarvis or other methods I am not sure, but they are digitized when looking at the image. So, I am just wondering if wish to engrave this image, what image mode do I select? Maybe grayscale? I thought if I selected Jarvis it might duplicate whatever is already there in the image. Just need a little help. Also, I have never done this before but I understand that I can take an image and assign a dithering mode to that image and export it. Is this true? I did engrave a photo of my granddaughter and used jarvis and it really turned out well, so this is when I found this image/drawing that I want to engrave but these unanswered questions I need to solve. Any help would be much appreciated. One more question. Would a grayscale image for engraving be the only type of image that would be affected by min and max power settings? I would not think a dithered image would be logical nor would it actually work.
Laser everything has the following video on setting up your dpi/lpi on any laser for any material… Might be worthwhile for you to take the time and some of these questions will be answered.
What do you mean?
Did you run it through something like imag-r to preprocess the image?
Images that have been preprocessed need to have the Pass-Through feature enabled on the cut layer or Lightburn will dither it based on the setting.
Anything you see on a computer screen is already digitized, so you might have to be more specific about what you mean.
The grayscale mode with a co2 is for 3d engraving and is difficult to get good results. Most of us use one of the dither patters. I believe I get the best results with Stucki, but you will have to pick which one you wish to use.
Use the preview to see where the laser is firing.
You did pick the most difficult operation for a laser… engraving photographs…
Hi Jack thanks for the reply. Well, I bought the image from a site on etsy GF5BUCKS. You can look at this guys art on etsy but here is the description for each of his images below:::
- You will receive (3) PNG images and they may burn differently!
- PS=highest resolution-highest quality, LB=file is processed in LightBurn using Jarvis, AI=dithered in Adobe Illustrator
This design will work with any laser engraver providing you know your machine settings.
So, I opened the LB file and you can see the dots everywhere on this drawing (Jarvis) then I opened the AI (Adobe illustrator) image and it also is dithered, then I opened the PS (PhotoShop) image, but this one has no dots whatsoever and is just grayscale only for a lack of a better term. So, back to my questions about the state of each of the images and how that brought the question of the “Image Mode” selection in Lightburn. Just a little confusing to me.
Did you watch the video? It should have answered these questions…?
If they have a pre dither done by something like AI, then you should use the pass though option in the layer to prevent Lightburn from dithering the already dithered photo.
Hi Jack, sorry for the late reply. Yes I finished the video late last night and it was very informative, thank you so much!! I did use the pass-thru and all is well. Some were having issues with the pass-thru, needing to reload and de-select options. Not sure if that was older versions of LB or what. Anyway, thanks again for your help it is much appreciated.
