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.
