Default Change greyscale to 'line drawing'

Hi guys,

I'm getting my company logo printed on the outside of some cardboard boxes which will be used to send our goods to customers. The logo is currently in greyscale but I need to give them more of a 'line drawing' kind of image because the printing technology they use can't cope very well with shades.

My question is, what's the best way of converting this image into something more suitable using Photoshop?

Reps for any help as usual

I'm not quite sure what you mean... Like this? If so, then that's just the posterize feature.

tell em "*******s" and send them a CYMK image and let them sort it out - do you have the original image to work with? was it a colour image to sort with? - in short give us the original image

Hi dudes,

I have the original image but it's a massive PSD. All I need to do is convert the image so it can be printed in true black and white, i.e. no grey or shades, just black ink. That one you have done Carpo is close but not quite close enough - I'm sure there's an easy way in PS but I can't find it anywhere! What did you use Carpo?

Just to check before I start going mad here - You just want a binary image version of that? e.g. black or white, nothing else?

Edit: Nevermind I failed at life, tried using some industrial machine vision image processing software that I used for one of my modules, and it proved too gay - the bottles always came out looking horrific

i used your image and two filters in photoshop - i can easily make it black if you want, at college atm so cant do it yet - you could do it yourself using colour replace tool if you want the lines in black on the image i made

Brilliant guys, thanks. I followed that tutorial then turned the image into a 1-bit bitmap using 50% threshold and I think it'll be fine.

I've attached it to show you.

Thanks!
