Subject: [Gimp-user] Question about RGB to CMYK conversion and print work

I'm helping a friend of mine create a business card for a new business. I created the card in GIMP and it looks great! The plan is to order cards through VistaPrint. Anyway, according to the VistaPrint website, they recommend uploading designs in a CMYK mode. Since I created my card in GIMP, it's in RGB mode.

Would it be safe to convert my image from RGB to CMYK, using ImageMagick for example, or should I recreate it using a different tool, like Scribus? I'm a Linux user. Alternatively, I could send the image to a friend who has PhotoShop and have her convert the image to CYMK mode for me.

Any thoughts or suggestions?

Thanks!

Peace...

I dont know.
But RGB2CMYK is a hell of a lot easier to use and for that reason it will probably work better. Just upload your file and its done.

Im a graphic designer/photographer not a geek (not any more, anyway). I like things that work right out of the box and this online conversion worked for me.

Thanks for the link. Would this service do a better conversion than ImageMagick?

Thanks!

Peace...

I'd recommend to not fiddle with it now. Vistaprint will do their own conversion, which is likely to be better than your conversion, since they do know their own processes.

In fact I had lots of "fun" some time ago, where I absolutely sent them a CMYK PDF file and they still fiddled with it, adding a little bit of black to my vibrant yellow, resulting in quite dull colors...

Thanks to both you, Simon, and Rick Strong for your comments. I opted to "roll the bones" with the RGB PNG I created, using the VistaPrint template, and the site seemed happy with the resolution of the image. The previews on the site looked good so I'm keeping my fingers crossed that the image prints well.

Thanks again!

Tom

Well, the business cards have been printed and they look fan-flippin-tastic!!!! They actually came out much, much better than I expected and my friend *loves* them! Thanks again for the help and Thanks to the GIMP developers for producing such awesome software! :)
