how do I make a match SWOP color bar?

I am using CS5. I am supposed to deliver a file to a client with a match SWOP color bar. How do I make this? Thanks a lot.

You are going to have to get more info from the about what they expect. Pure CMYK values in SWOP V2 (what profile defining SWOP?). A G7 certified proof bar?

This may help:

Re: how do I make a match SWOP color bar?

In the absence of any information from the party involved, what SWOP profile would you guess that I am safest using? Project has a tight deadline and all I know is that is going to be printed in a magazine. Would you guess that I should deliver the file as CMYK or a TIFF file although I read this in the document that you attached, Andrew.

Files representing print-ready material should be exchanged only as CMYK data using the TIFF/IT-P1 or PDF/X-1a file formats or their future versions. The use of non-standard, application or native file formats is not permitted.

Thank you for saving my ass.

The last thing you want to do is deliver output ready CMYK for the wrong device. Deadline or not, this is super dangerous. Send tagged RGB (probably something like sRGB or ColorMatch RGB) unless you get specific information, ideally a profile for the process.

when I was printing something on a Lambda, I attached a colour bar by which the printer was set... probably this is what they ask here too.

(when they have the known colours they set their custom profile so it will print with the intended colours)

Probably 8-bit RGB image as AdobeRGB. TIFF (possibly with LZW-compression to chop size in half). If it is not an image file but a regular document (e.g. from Illustrator or InDesign) choose PDF/X-1a (with crop marks, bleed, color bars).

If they need it in CMYK and with some specific color bar they really should give you more information about exactly what they want (what CMYK-profile, exactly what color bar – and where you might acquire it). If not you just have to make a guess... :/

Thank you, Chain and ShadowLight. I sent it off to them as a PSD with an embedded profile just to be safe as they never gave me a CMYK profile.

A flattened TIFF-file would probably be better than the complete PSD due to filesize and compatibility (the PSD might require Photoshop, while a TIFF is accepted by a lot more programs).

That being said, they probably have Photoshop so it might be cool
