Hi, I'm new to Photoshop and I'm trying to take a screen shot image and save it to a PDF file that a professional printer can use to create a postcard.

I created the the original image as a 6" x 4.25" 16 bit RPG at a resolution of 128 ppi and saved it in high quality JPEG compression format as a PDF file. I sent this file to the printer who called me back and stated the resolution needed to be at least 300 ppi. (He said dpi but I know that refers to what a printer uses vs ppi for screen resloution.) He also stated the file needed to be saved in the CMYK format.

I could sure use some help to get this right before I resubmit it. What I have so far is this:

1) Opened the original saved PDF file and changed the resolution to 300 ppi.

2) Changed the Image Mode to CMYK color.


What I am confussed about is how best to save it?

1) Should I check the "Use Proof Setup Working CMYK" or leave it unchecked as the default suggests?

2) Should I stick with the High Quality Print (Modified) setting or use High Quality Print, Press Quality, or some other setting?

3) In the original file, I used JPEG High Quality compression. Should I change that compression setting to "None?"

4) I also think I selected the "Do not Downsample" for the original file and unless that was a mistake, should I continue to use that compresion setting as well?

Please keep in mind I am only interested in the quality of the printed product and I do not care how large the file size turns out to be. 50 - 100 MB is no problem, as I will save it on a CD-ROM.

Thanks in advance to anyone who has experience in making files suitable for professional printing. I have used other photo imaging software in the past for website creations, jpegs, etc. but this type of formatting is new to me.

Do you mean that you reworked the original picture, or just upsampled the one you had originally saved for him? only the first one is the good solution, provided that the image is large enough.

Normally, the printer should have recommended you one particular CYMK. It can mean many things, like when you say red, some will think burgundy, others bright red.

I'd think press as it is going to a press, but I'd recommand looking in the manual to know what each setting means exactly.

I'd set it to none, as some very old rips have trouble with JPEG encoded images, and you stated that filesize is not an issue.

Yes, you do not want any downsampling.
