Map Drawing Line issue

[heyskull]

I have a file that was originally made for a pen plotter with multiple coloured lines.
I would like to bolden the lines so I can print it.
At the moment it is making them all hairlines and are hardy distinguishable.
This file has been created from an ordenance survey map and is highly detailed so I cannot select each colour to change the stroke width.
Is there a simpler way to do this?

Thanks

Is the problem that the file is not CAD or vector in anyway - but a bitmap?
My first thought would be to use photoshop select by color, copy and past into it's own later, then add the stroke there. Rinse and repeat for each color. If I understand correctly.

What software are you using?

If using Illustrator, you can Select>Same>Stroke Color to select all of each color at a time.

That's what I was going to say - but after I looked up - ordinance survey map, I started thinking maybe he's working with a bitmap image.

aaand I just re-read the OP - and he said the file was created for a plotter..... so now I'm confused why he couldn't just open it in Illy or something and select same stroke colors.....

I'm thinking it's hilariously complex...
I'm afraid you'll have to find a way to open it, at least in corel, there is a find feature, set it to given color, change width of outlines, done. Or select the whole set and give them all a bump.
One sloppy af way would be to export into a png at 1/5 scale, then scale that up. It will also pixelate everything else, and while the lines would be 'thicker', they'd be pixely too.

It must be complex - in my head it seems like it would be really simple in illustrator, but I guess I'm missing something.

Hi

I am using Signlab. Can it be done in Signlab. I also have corel suite and Adobe illustrator. I mainly use Signlab and the other ones are there if Signlab struggles to import a customers file.

Thanks

You haven't verified whether you're working with a raster file or vector.
