How do I create a Hairline outline in ai? I am printing to a laser that only accepts colour as raster to engrave and a hairline RGB Red as vector to cut along. The 0.1mm stroke does not work.

The pathfinder "Outline" creates strokes of 0 Pt, which are in fact Hairlines. Create a graphic style out of this and apply to your stroke.

Wouldn't it be just great if Adobe fixed this. I guess its simply not possible.

None of this works for me and I simply can not cut with Adobe and the universal Laser system. Hopeless, thanks

Hello @umututkus,

Thanks for reaching out. Would you mind sharing some more details, like the exact version of the OS/Illustrator, details about your workflow, and a screen recording of the problem (https://adobe.ly/4aprck2), so we can investigate this further?

Looking forward to hearing from you.

Thanks,

Anubhav

PostScript doesn't define hairlines. If the stroke is smaller than a device dependent

limit or zero, then the stroked path is drawn by the smallest rasterized(!) line which

the device is able to draw. That's much more than a device pixel. For rasterizers

with raster cells one may get about two lines per raster cell (cell width= 1/Lpi).

Some tests, mainly p.13:

Help text from PSAlter (PostScript editor by Quite):

setlinewidth operator
width setlinewidth -
...
A width of zero is accepted. The effect of this is implementation dependent, and means 'draw the
thinnest possible line'. The use of this is discouraged, because on some devices, such as high-resoution typesetters, single pixel wide lines are effectively invisible.

The last statement is wrong. The thinnest possible line is much thicker than a single pixel.
