Adobe Photoshop/spot colour

Question
QUESTION: Hi there

IM a painter, ive done some paintings i'd like to screen print onto tshirts.

The printers suggest separating the colours into separate layers

this painting in particular (red/yellow) (top second right) on this website:

http://www.davidrusbatch.com/paintings-2013141.html

The idea being 3 screens -  one screen for the red, one for the yellow and one for the black.

What would be the best way to do this in Photoshop?...a method to preserve as much of the painted looks as possible (half tones?)

Many Thanks

DAvid

ANSWER: Good question David. But I need more information from the printer. I would suggest breaking out the channels from a CMYK conversion as separate grayscale files. I'm somewhat curious why they are asking you to do it, as this is usually part of their job. Did they send you specific requirements, such as color mode (CMYK possibly?) and file format? Also color profile (I presume a Euro type).


With best regards,

P.S. correction: I may have submitted this as a final answer on accident. Sorry. If you need to resend as a new question, please do so.

QUESTION: yes i think cmyk conversion was mentioned (and spot colour).

They suggested i do it to save money..

How do i go about it?

Ive read about "bitmap" too for half tones....would that be helpful too?

Thanks

David

Answer
Can you send me more specifics? It's very hard to help you without knowing what they need exactly. Spot color and CMYK are different printing processes. Bitmap can be a file format or a fancy word for photos. To convert to CMYK, you need their preferred color profile. What version of Photoshop are you using. I can tell you how to convert (in PS5 it's menu Edit=Convert to Profile).
