I am guessing that there is an easy way to convert a tonal image to spot colors. I’ve heard about people/pros doing stuff like this with Channels. Is this possible?

Here is my logo: <http://dininfo.com/logo.htm> that needs to be converted to spot color. I need to print this on an orange shirt. So the only colors that need to print are the white & black.

Again, is this possible?
REALLY appreciate ANY suggestions!

Respectfully,

Here’s < http://graphicspalmbeach.com/forum/ChannelHelp/channels.html> a link to a quick tutorial I did for another user a while back. It will work for yours too.

Thanks for the tutorial LRK, but it doesn’t indicate that you can save the white highlight to its own spot color.

Select the white highlight, paste it into the orange channel and delete it from your orange and black channels. As I see it, you only need two channels, orange and black. When you paste into one you delete from the other. You need to so this in the order that the image is built. At the end you will just select the white areas by clicking on the later to be copied, and do Option-Return. While you have this selection, paste it into the orange channel and delete it from the black channel.

Note: Corrections have been made to above instructions. Sorry Scott… I’ve got too many things going at one time and not thinking this through. 🙂

Maybe I’m not on the same page with you…
I need to print this on orange t-shirts. I don’t want to print the orange on orange, so I was hoping I could print the shadow and the highlight that make up the shape (3D look) of the icon.

Possible???

Oh, okay. You will just be printing the white and black? I think that can work. i’ll work on something and send it to you. It’s easier than explaining. 🙂

Okay… You are using white and black on an orange tee shirt. I’ve got it.

I’ll post what I have and you tell me what you think.

WHY YES!!! That’s PERFECT!!!
On my screen this looks a little blurry. Is that just my screen?

My boo boo. I forgot to delete the edges after selecting the original image.

Select your image outline and invert the seletion. Then delete this from both channels. I’ll post a new image shortly.

I’m waiting patiently. I’ve read over the tutorial, tried to do it myself, and it STILL doesn’t make sense.

Take the RGB file and do a mode change to multichannel. Throw out the green and blue channel.

Convert to grayscale.

You need to do a LOT of clean up due to the jpg artifacts is this is actually your production file.

Nothing… but you will need to be able to do this. You will need the channels saved as a DCS2 file. Are you going ot try or shall I send you my file?

Also, I used Cool Gray 1 as it’s the closest pantone color to white. Your printer can change the channels.

I’d rather use your file. Seeing the file and reading over the tutorial should help me better understand what is going on.

And you’re right, I need to learn this!

Thanks TONS for your help!

Scott, You should print a negative of your Blue channel (for the White ink) and a positive of the Red (for Black).

I am not an expert on printing to fabric… so it would be wise to listen to Todie for the rest…

Also not sure about size but if you are printing it the size it is, the resolution is low. If you will be shrinking it at least 50% it should be okay for a tee shirt.

Thanks! 🙂 I’ve received a lot of help lately with photography so I’m just giving back a little.

I just sent a stuffit file containing the PS work file with all layers and channels, a PS file with just the two channels, and a folder containing printer DCS2 file. I also sent the following note. If anyone has anything to add please do… It’s time for me to fix dinner. 🙂

Scott,

Please make sure your printer tests this DCS2 file first and you see the first shirt from the test run to approve it.

Printer can change the spot channel colors if needed.

Resolution is low but file size is big enough to compensate.

Just for a disclaimer, I absolve myself from any responsibility if you use file as it is. Make sure it is right when you take it to the printer. If there is a problem you have the original #1 file to work from.

Thanks,

Linda

Oh, I just love this industry.

I absolve any responsibility and let the next guy eat it…..

The software manufactures do it.

The photographers do it.

The designers do it.

and guess who eats it?
