jpeg to tiff

Is there a good technique for converting a jpeg file, presuming you have the resolution, to a CMYK tiff image to be used in a printed piece?

You dont really want to use a jpg for print. You can change the rgb to cmyk under ....image-->mode-->cmyk, then save it as a .tiff, but
jpg's will be in 72ppi, which will result in a fuzzy image if you print it. You could increase the resolution and size to what you need, but then you are making something out of thin air to compensate for the increase in resolution.

werd. :D

I have been getting some images taken with digital cameras, that often have a size of 18 inches by 22inches at 72 dpi. I resample the image down to the required size, usually a 3 x 2, and in doing so the image then comes up with an acceptable DPI range. If it is over 300, I change it back down to 200. This is where I need to convert it to a tiff image. The procedure we have used in the past, with psd images, is to select auto levels, then do an unsharp mask, and then convert to CMYK, and save as a tiff. The problem I am seeing is that I am getting a radical color shift from the JPG image to the CMYK image. Any good ideas on how to prevent this shift?

Well if you are getting the images in 72 pixels, then your printout will look best at 72 pixels (which would be your monitor) if you run that thru a professional printer your gonna see some blurring, even if you resample the image so that you have it set to like 300 pixels.
You are seeing the change in color because you are converting an rgb to a cmyk. You are no longer seeing those same colors in red green and blue, but cyan magenta yellow and black. So there will be a slight shift in color. I cant think of anyway to get away from the shift. Have you tried saving the image as a psd before you convert to cmyk? Not sure if that will make a difference. Someone with more print experience than me might know what to do. I remember running across that same problem and not finding a method of fixing it.

Hope this helped a little.

oh yeah an werd up! hehe

Jpg should only be used for the web....
