New to Laser engraving

Post by rodrinat »

Hi i am Rodrigo Natero from Argentina and i am new to laser engraving. I tried to make some photos but the detail i got is very bad. i use a 100 W tube at 100 m/s and 12% power with and interval of 0.086. the material i´m working on is MDF.
I will leave you the photo i´m trying to engrave, the preparetion i made to the photo and the end result. Any advice on how to improve will be well recived.
Thank you very much

when the image is rasterised it is loosing definition due to the algorithm, you will get better results in processing in a graphics package as there is usually a choice of different algorithms to process the image, if you are doing a lot of photos get a specialist software called Photograv. your interval of o.o86 equates to 295 DPI, also MDF is a dark colour so reduces the contrast of the image, try on Birch ply, poplar or a light coloured wood

Hi,

You should look to get more contrast in your dark areas, and use a more detailed resolution to your b&w picture ( At least 200dpi ore higher...)
you may choose an other algorithm to convert the image to b&w. Look for an irregular frequency modulated one. Like most desktop inkjet printers do work with.
Also mind that your power adjusment could be a little bit higher to get more contrast too.
What I can't see is the actual size of the final engraving. so I have to guess it is not enough detailed because the resolution isn't high enough.
Please let us know your improoved results.
Thanks
Reiny
