PDF Issue: jpg colour not matching bg

[Leprakawn]

I have experienced this before, but do not remember how I fixed the issue!

I am making a .pdf with text, vector files and photos, and I am using Freehand to set everything up, whereas InDesign is used to create the PDF.

Issue:
I edited the photos with PS, and put a bg colour to match the surrounding area, which looks fine in Freehand and InDesign; however, after the PDF is created, the bg colour (within the photos themselves) is slightly off.

I thought that if I snagged the surrounding area's bg colour in the final pdf version and used that colour as the bg for the photos, it would work... but I was wrong.

BTW, I just started experiencing this again after I tweaked InDesign's pdf settings, which was because one of the images was coming out a little crummy.

Do you have any idea what I need to do to fix this? Muchas gracias!!

Maybe use PNG or Tiff instead of JPEGs?

I did not think of that! Thanks for the suggestion; I will try it out and post a response with the results!

When you were in Photoshop was the image edited as a RGB or indexed color? As an example when editing gifs you have to convert back to RGB to do a lot of the editing. Photoshop a a fairly decent "save for Web" feature where you can moidify the number of colors, the type of dithering, etc.

Can you save the image as a gif? If not play with the level of compression as a jpeg file. I highly reccomend using PS over some of the non-industrial strenght software programs that tend to make unwanted modifications to your graphics.

Actually, I got really lucky with the printers from CopyMax; they did not print the colours like my printer. Next time I encounter this issue, I will do as you suggest. Thanks!
